I've been acquainted with the Drill Dr. for about 25 years. We got one where I worked and at first I thought it was another gimmick. After finally learning to use it and using the proper finesse to fit the bit in the chuck just right, it was a great tool. Sharpened many bits with that little sharpener. I didn't use the split point function very much. 10 years ago I found one on sale on clearance at Lowe's and picked it up for about $70. It's a different model than we had at work but still performs the same functions. Call me an old fuddy-duddy, but I'd rather use the Drill Dr. than the General Tools sharpener. It's much quicker to sharpen a bit with.

Good job on this one Project Farm. I’ve been using a drill doctor 350X for around 15 years now, picked it up for $28 from someone who never bothered to take it out of the box. I’ll freely admit, it does a better job with the bits 1/2 inch and under than I can do by hand. The larger bits are a lot easier to do by hand. Those who watch my channel (equipment and auto repair stuff) know I’m a big fan of Norseman bits. You’ll cry a little the first time you buy a set due to their cost but the quality is excellent. I’ve found that the DD, once mastered, provides finished edges very close to the quality of the factory edge. I have a different model of DD than you, and setup is quicker and easier on mine but it’s not as fancy of a model as the one you are using here. I think you could see a significant improvement on narrowing the gap between factory edge and DD sharpened cutting times with a little more practice and higher quality bits. Keep up the good work man!

[@joakimgrundberg4637]

Thank you for yet another very interesting test. I only recently discovered your vids and I love them! I have the 750X type Drill Dr and a bit takes at most 30s for me and maybe 45-60 if split point. The good doctor always brings my Dormer bits back to new mint condition. It has reduced my spendings on new bits and really worth every penny. But it takes some time to “figure out” the details that really makes the bits sharp. Took me probably 2 hours of testing. Sharpening, drilling, new setting, test drilling again und zu weiter. Different bits requires more or less aggressive setting in the chuck alignment port for example. Then a couple of years more to really fine tune the skills. With that said, my wife can use it and still produce excellent results. One comment on the video (don’t know if it has been covered already or not) is that when sharpening really dull or damaged tips (or always when setting large removal setting) it is also best to reposition the bit in the alignment port one or maybe two times as the large amount of material removal changes the angles relative to the best setting from the alignment port. Then finnish the bit of with one gentle last turn in the grinder after the last reset. This produces the best results imo. Also an experienced user first taught me that the 118 deg in the alignment port referes to the relief angle and not the drill bit point angle (the latter is either 118 or 135 and is set in the grinding port where there is only two settings). In the alignment port of the good Dr the “+” stands for more aggressive relief angle and “-“ for less aggressive but better finnish and 118 is the intermediate. So imo you took a bit and grinded it to a 135 deg point angle with less agressive relief angle i.e. slower but with better finnish. No criticism but just to be clear that the Dr has some potential to tailor your bits to each occasion. I hope I made myself clear but if anyone else has another understanding or explanation please respond. Sorry for any bad English, its my second language.

[@undrtakr2222]

@Joakim Grundberg I agree. The 1 part, that you did leave out, that I did briefly mention, in my own comment is, that it also recommend's to make an equal amount of (2)1/2 turn's(1 full revolution of the drill bit.), to make sure, that the tip, is truly centered to the center of the flute's, as well. Also, it also recommend's, to not turn quickly, or aggressively pressing down on it, or it will cause the drill bit's to "burn" and lose their rigidity. And, when doing the split tip, there is a function to measure how far you have gone with it, so you can go the same distance, on the opposite side, to keep the balance of the drill bit, as well. BTW, I also have the 750X Drill Doctor, as I used to sharpen drill bit's, as well as do the split tip's by eyesight and only my hand's, with a bench grinder, before we got the original Drill Doctor, shortly after they came out, when they cost like $325.00(US). Mainly, because it was so efficient to use it and it kept our 2 bench grinder's free, for other's to use, to grind actual chisel's, prybar's, or whatever needed to be ground, or wirebrushed at the time. It take's me about 2-5 minute's(Depending on the diameter of the drill bit, of course.), per drill bit, to sharpen them. And, before I forget to mention this, again, like I did with my comment above. Do NOT allow the drill bit to turn in reverse, ONLY turn it in a clockwise direction, or you can cause flaw's in the bit, as well as issue's with the machine, as well. Such as, the grinding wheel grabbing the drill bit and ripping it loose from your grip. And, very good point, with the recentering it in the first step, before grinding it, to do the relief grind to the back of the split tip drill bit's. I almost forgot to mention that, as well. I do it without thinking about it, anymore, as I follow a specific sequence, as I sharpen the drill bit's, only thinking about how many full rotation's of the drill bit's, as I sharpen them...

I've been sharpening large (30...90 mm diameter) drill bits with expensive professional tools for few months, and to me the drill doctor seems like the best option. It makes some of the interesting twists and turns just like the bigger machines I used, so I expected the drills to perform well. It's not quite the next level yet, but it's compact and didn't cost as much as a car, so you get what you pay for. As you said, it takes a lot of the art out of the equation, and that's exactly what you want in a professional setting. It makes the process faster and reduces quality variation significantly. If you have a lot of drill bits to sharpen on a regular basis, you begin to appreciate these factors even if the machine is a bit expensive.

I set up the General Tools' predecessor version (when it was made by Craftsman (Sears)) which I found in a drawer in our community woodshop. Not having a bench grinder wheel readily available, I set it up with an angle grinder holding a metal cutting wheel. The wheel spins pretty fast so I swing back and forth very quickly to minimize overheating. It does a great job sharpening drills with no burning. It was a pain to set up and fixture the angle grinder but in our shop we don't dull our drill bits that often. Once set up, it is pretty easy to use.

[@Enjoymentboy]

I watched this video again for the second time just a few days ago (yeah...I know this video is 2 years old) and it inspired me to finally do something about the huge amount of dull bits I have. I wasn't willing to shell out close to $300 for the DD X750 but looked into what was available around me and the DD X2 happened to be on sale for half price. I liked the idea that it would also sharpen knives, tools and scissors so I took a chance on it. Boy oh boy was that ever a great idea. I have just finished sharpening over 500 bits (I stopped counting at that point), a bunch of knives, 2 hatchets and 1 pair of shears and the thing is still going like new. I literally have given it years worth of use today alone (5+ solid hours of runtime) and the last bit was sharpened just as well as the first one. I am blown away. Gone are the days of buying new bit sets just because I was too lazy to do something about all the dull ones I have on hand. I even reground a half dozen large bits (3/8-1/2 inch) that snapped during use and while they are shorter they are back into cutting shape. Needless to say there was quite the pile of filings collected but the diamond wheel doesn't have a mark on it. Well worth the money. If I have any complaint (and I don't) it would be that the knife/tool disk abrasive is a bit too coarse for my preference. I checked on the DD site and they have a replacement kit with disks and a wheel at a good price but I would really like to see multiple grits available. I'd like a 200, 600 and 1000 to reshape the edge, refine it and then get it to that razor blade sharpness. but the ones that is included does a heckuva job on its own. Just need to follow up with my ceramic hone and it is shave sharp. Appreciate you doing this video and I'm really glad I watched a second time.

[@Enjoymentboy]

@@karlwithak1835 I get what you're saying but it was at MOST $100 in labour. As well when I factor in the cost of the bits they cost me well over the cost of the sharpener. There is no possible way I could have bought all those bits for the $103 (after taxes) that I paid for the sharpener. Then I add into it that the sharpener also does bladed items such as knives, axes and scissors, and does a pretty nice job at it to boot. Some of the 1/2" bits I saved were $10 a piece when I got them brand new. These weren't all your chinesium cheapies that you get from the dollar store. Lastly there is always the time factor in going to the store to buy new bits. That has to be weighed in when comparing to the time it cost to resharpen them. The store is close but not close enough that it would take less time to buy than to fix. The mindset of the disposable society isn't something I ever bought into. My grandmother lived on the streets as a kid during the depression and she had to learn to do the most with the least. She taught me to fix things until they were unfixable and then reuse parts until they couldn't be reused and then to repurpose them until they had no purpose. People may call that cheap but I call it smart. Why buy new when repaired does just as good? I have no interest in trying to impress anyone with my shiny new "whatever". It's function over form for me.

[@Enjoymentboy]

@@karlwithak1835 Not sure what industry you work in but I'm not making close to $180 per hour ($1000/5.5). Even if I figured in $30 per hour that's still around $165 max so 1.5x the cost of the sharpener. And then when I factor in I was doing it in my spare time while watching TV the time factor really isn't an issue. But if you'd rather toss them and buy new, have at it. I'm just not that kind of guy.

[@normcameron2316]

In 40+ years of drill sharpening, this pretty much confirms my experience. There are a lot of variables not mentioned here with used drills such as web thickness[the center of the drill], damage to the flutes on the outside of the drill, helix/spiral angle/twist. It would be really interesting to take a bunch of new Dewalt drills of the same size and resharpen them all with the different machines and compare results with the factory one. It would be interesting to see how the factory sharpens them. One thing that stood out for me is the General Tool sharpener, you were using it on the face of the wheel which gives a hollow grind although the sharpener is commonly used on the side of the wheel. How does this affect performance? Testing, testing, 1,2,3. It never ends.

I spent time using surface grinders, milling machines large radial arm drills (capable of drilling large holes in armour plate), large power presses, sheet metal benders and guillotines. I spent time learning MIG, TIG, stick, gas welding, brazing, and oxy-acetalene cutting. Outside the workshop, I spent several months in the draughting office creating drawings for components we might fabricate and machine, I spent a few months in our optical instrumentation department calibrating theodolites, telescopes, binoculars and inclinometers, amongst other servicing duties.

I've always just held the bits by hand on a bench grinder. I use a large magnifying lens on the grinder to better see the edge I'm grinding and have found this faster and easier than any of the attachment tools. Downside is that I just eyeball the angle.

[@mrcryptozoic817]

I do the same. The only reason it's dull, is the cutting edge is worn down, not the whole thing. So wear down the rest of it by at least the amount already worn off the cutting edge. And it's easier to do it in two steps, two angles: grind one just behind the cutting edge and then a little more at the heel.

[@hgwaterous]

The drill doctor is the only one tested which can center the drill bit, resulting in even flutes. Even flutes are important to keep runout to a minimum. That makes bits stay sharp longer and makes the holes closer to the nominal size of the bit.

[@ProjectFarm]

Thanks for sharing.

[@SonOfMrGreengenes]

With proper care the General attachment also can grind both flanks exactly the same. This is easily tested by drilling some steel with a sharpened bit and then cutting power while pressure is still applied. If the bit is sharpened properly then there will be an equal chip or curl on both sides and the hole will measure to the proper size... not oversize. With the addition of a modified part the General can produce factory quality drill bit point geometry on all size bits from 3/16" to 3/4".

As someone who has sharpened thousands of drills over the years, I consider myself an expert. I could easily spend a hour just explaining many of the variables and engineering involved in drills and drilling. The design of a drill and putting a hole in the thousands of different types of materials that exist, is a science. As both a tool and cutter grinder and a toolmaker with over 30 years experience, there was a huge list of things wrong in your analysis, but I will only mention a few basic things the average person should know. For general purpose auto and home repair, the drill doctor is the best product of the bunch. If you don't mind the cost it's the only one worth buying, but unless you're sharpening at least one hundred drills a year, it would take a long time to justify the expense. Buying a new drill is more cost and time efficient. However, once a person can understand how a drill is designed to work, it is just as easy to sharpen the drill by hand. I've taught guys how to properly sharpen a drill by hand in less than an hour. One thing I think you should have done was point out the necessity of using a center drill before using a drill. Only very soft materials do not require center drilling. Speaking of which, only materials deemed to be of a specified difficulty of machining, require a 135 deg. chisel point angle. And of course once you reduce the point angle to 135 you need to add a split point. However, there are times when even a standard 118 deg. point will need a split point as the drill web can get too wide as the drill is reground too many times. That's part of the minor details which just can't be explained in a short video. The reason it is almost impossible to duplicate the performance of the factory drill is due to the finish. Their cnc tool grinders use special grinding wheels which produce an amazing finish and contribute to their effectiveness and longevity. Of course, I'm referring to decent quality manufacturers, not worthless Chinese crap made out of junk steel. But unless you're drilling hundreds of holes at a time, you'll be fine with hand sharpening or just buy new.

[@ProjectFarm]

I've used most industrial drill sharpeners made, a drill sharpener does not sharpen a drill like some kind of robot.

I learned at an early age how to sharpen drills on an old-school grinding wheel. I've never looked back. I will say a belt sander does a better job. One tip is to try to keep the drill cool because excessive heat will allow it to become dull much quicker. I experimented with oil/coolant before and found that plain water works just as good. If hand drilling many holes in stainless, the keep a cup of water on the side and dip the bit frequently. It does make a difference.

[@KBS117]

Heat takes the temperature out of the metal, making it softer and will loose its cutting edge easier. People grind the ramps too steep and this causes bits to grab and hurt people.. drill doctor eliminates those factors.

[@JohnThomas-lq5qp]

Years ago I worked at a large slaughterhouse that had a lot of walls covered in heavy stainless steel. I used to burn up stainless steel bits all the time until I figured out better to use a slower speed, watch the metal if it was overheating and to use oil or tapping fluid. A lot of these walls had water inside so if you drilled thru with a super hot bit the cold water would kill the bit. Great tip using water to keep bits cool.

Great overall review, and interesting testing setup with household types of items like the home scale, old spoked wheel, and the weights! Clever/scientific. The reason I like the Drill Doctor is that it does contain the motor system, meaning you can just take it out of the bag or box and use it right away. After some practice, it only takes seconds to do the actual bit setup on it, then go through the sharpening process. I just sharpened some terrible 3/4", 23/32" and 21/32" bits, and besides the incredible noise of the Drill Doctor, it has been fun.

Thanks for the feedback.

Never did use a drill sharpener that can do it better than me just going over to bench grinder and sharpening by hand. The one at work collects dust. As a Machinist since 1984....I must have sharpened at least 1,000 drill bits. Used to be able to do as small as #36. Now, with 3x magnified Safety glasses....all good until #7 (.201) By 1/8 , I am 75% sure....and smaller and only 50/50 change it cuts as new :( Best way to find out if someone really can sharpen by hand.....Cut off the tip of drill bit, then give it to them :) BTW love This guys video's. Unbiased , laid back , well tested. Thorough ..the best!!

Thanks so much!

I wished I had your skills, I've tried many times to sharpen bits by hand, I just cannot get it right. If I do get it right, it's by accident and then can't repeat it. Lol, I will be getting a bit sharpener. I can do a lot of diy things, I have mechanical skills, but the two things I can't do worth crap is knives and drill bits. 😡

@@garyr7027 you got to talk to the old guys at work machine shops the old guys can tell you where you can get good stuff and how fast you can you turn and how hard the metal is and what type of metal is going to stick to metal you got to be careful that's what you use lubricant for its not to cool it off but they do have coolant to cool off but if you can't keep the speed and the pressure on the quality drill bit it take forever to figure out how to make a hole I've seen old timers man calls the hardest parts of metal of no mankind you know I would get it every time I've seen the best machine shops in the world do unbelievable stuff all around this planet and understood nothing is impossible if you keep your mind to it and study I can understand that in the jobs they do look so easy that no man can do for the rest of their lives because they're not knowing what's happening always be aware when you trying to do something I don't care if it's drilling a hole driving a car or talking to somebody beware be respectable with yourself and your mind and passed that on to another person and all things will get done remember we're all here to help each other they're stealing our stuff from other countries because of our politicians don't want us to do it to be good we are the powerfulest people in the world we are the Christian Nation we follow God there's nothing that's going to stop us to be the best unless you're doubtful remember what God Said you get anything you want from him if you're with him you're his and that's all there is to it and you understand one thing when the little midget can take them 20 men and he's the kindest man in the world who are you to think you are the Giants that could control the world when you could be taken down by a midget imagine did he create himself I don't think there's a Creator but him so yeah that is a question that who created The Big Bang with no material that science can't explain oh yeah. So God created himself that's how come he's so powerful and nothing can stop him and we thinking like God is our weekend I know we can do a lot of things

@@garyr7027 little late to the party but sharpening a drill bit is not just creating one motion with the bit on the grinder. You are first creating a cutting edge, then pivoting the relief on the grinder so that the cutting egde is the highest part. Do for both sides until the cutting edges are the same length. Start fast on the edge and slow down after you come off of it to ensure that you remove more material behind the edge than from the edge itself otherwise it will rub.

[@Giant_Meteor]

The 'factory-sharpened DeWalt' probably had a special coating that was still intact, so it may have performed better as a result of material composition, rather than better sharpness.

[@ProjectFarm]

Thanks for the feedback.

[@tiggywinkle1000]

They teflon coat them.

[@aevangel1]

@@tiggywinkle1000 NO, just no. Teflon it too soft to be used as a coating in metal cutting. Teflon coated cooking pans can not even hold up to a dull butter knife. The typical coatings for drill bits are as follows from most to least common: Black Oxide, Titanium Nitride (gold colored), Titanium Aluminum Nitride (dark purplish black), Titanium Carbo-Nitride (rose gold colored) Source: This grumpy, over 20 year machinist....

The first test I've seen of these devices (and I've been considering them for years); a most useful test/report. Thank you.

i got an interesting idea for a video: Comparing oil filters for cars. As in, how good are they at catching tiny pieces of metal and sand and how fast they rust. I once saw a video of a guy demonstrating how easy bad oil filters can rust and actually introduce their own rust into the oil system.

[@DashCamSerbia]

Also, is it better to use taller filter (if there is room to fit), because it has more surface area?

[@ProjectFarm]

Thanks for the video idea.

[@MindBlowerWTF]

@@ProjectFarm getting salt spray equipment would be a decent project. You might even do a video on building it to get feedback on it, before it is used in testing.

[@DashCamSerbia]

@H Higgins Yeah. The OEM filter for my engine is only available at the dealers, while in the stores I can only get aftermarket ones. The OEM (Purflux) is lower profile than those aftermarket ones for my engine. And I am looking at my engine bay, an they can fit and since the surface area is bigger, they will not saturate as quickly. And yeah, inf on the valve pressure is not listed for all filters, and it is not the same between diferent makes.

[@greylocke100]

@H Higgins use the cross reference book. It will tell you the manufacturer

[@azinfidel6461]

Excellent set of tests. You're correct in that some brands of drill bits are absolutely useless as the quality of the steel is garbage. I have a General drill sharpener but became very impatient trying to set it up so I have never actually used it. I also have the original Drill Doctor 750 which I find to be vastly easier to use and have gotten perfect results with it. The split Point feature on it is most useful to me.
