There is one important category he leaves out that I would like to see and that's longevity/durability. Like use the top rated tools around his shop and make a video a year later revisiting the tools and any issues that came up from prolonged use. For instance, the harbor freight grinder may run faster than a DeWalt, but if it can't handle that power and burns up after less than an hour of run time, that would be very helpful info

[@TKC_]

Nice. Just a longer term comment. I’ve had that drill doctor for more than 5 years. I use it for metalwork on a lathe and drill-press mostly. I do tend to mess with the lip geometry in the +and - slots like you did at 135 but for 118. This determines how aggressive the bits are. There is a little bit of a learning curve to it but with steel you know if you did it right in a hurry. A properly sharpened bit can go through many inches of steel where a mistake can’t make it through 1/8” steel. And split points are where it’s at.

[@weldchip]

Do you not find that the drills you sharpen on the drill doctor cut slightly oversized on the lathe? I had that problem with mine which is why I eventually retired it. If you watch when boring a hole the swarf off one flute will be slightly thicker than the other or worse it only cuts on one flute, I think of they made a better drill holder collet it wouldn't have the problem

[@TKC_]

@@weldchip if you grind uneven this happens. I either count the time per side or spark the wheel out so it’s not cutting either flute anymore to get even chips. I generally don’t rely on a drill bit to be better than 1/64th. If I need a hole that tight I ream or bore it. I use one of those hf drill indexes that have every size known to mankind to always have something close but undersized and a small set of reamers for common sizes. Oh and regarding the collet yea that can be a little fiddly to get it seated in there just so. Shimmy it around while you tighten and don’t overtighten.

[@ProjectFarm]

Thanks! Thanks for sharing.

[@firesurfer]

@@weldchip For precision work you need a grinder with a proper guide. Most of these sharpeners are nowhere near good enough for machine work. There are good ones, but they are expensive. See Aboms videos on sharpening with a grinder.

[@brizzle8797]

I guess if we're getting down that far into things I wouldn't turn these as Precision sharpeners. If you're looking for precision it's time to break out the boring bar I would think. I just use drill bits to get to the rough shape or if I'm just making a bushing or a washer or some other nonsense like that I don't worry about it but if I'm trying to hit close tolerances best believe it's going to be from a boring bar.

This video is very timely. Just a couple of days ago, I was drilling a bunch of holes in some mild steel and the bit started wearing out. After every few holes, I used my old first-generation Drill Doctor to sharpen the bit. It was working great until it suddenly wasn’t. Looking at the tip geometry, it was way off and putting a small bevel on the leading edge. I couldn’t figure out why, so I freehanded it on a bench grinder for the remaining holes. It got me thinking it was time for a new drill sharpener and I looked at this channel to see if there was a recommendation. A day later, here it is! Thank you, Todd!

[@jeffshackleford3152]

If you are in the market for a new sharpener, I would look at the mrcm mr 20g or one that does larger if you need it. I bought that one and it is superior to the drill doctor in every single way. Depends on how you plan to make your money back though and the rate at which you use them.

Very nice! One thing not covered is accuracy of hole diameter. (how equal to center the two sides of the bit are ground.) If the center of rotation is off center of the drill blank due to inequal grinding the hole will be oversize. Another thing is the type of grinding wheel. The stone wheels will only sharpen a relatively small number of bits correctly compared to the drill doctor with the diamond wheel.

I'm in the same position as you, but sharpened my first drill bit only 20 years ago. I worked in a shop with auto lathes pumping out house fittings and stuff non stop- it was a GREAT test of your sharpening skill as you could easily measure number of holes drilled AND some of the holes had a tight tolerance and so any uneven sharpening was picked up.

[@weldchip]

​@@ProjectFarmyeah it takes a bit more work to dial in to the correct angles and the scale on the flute setter isn't great but once you get it dialed in it cuts the drill point and flutes way more accurately than the drill doctor by a significant margin and is way more repeatable/faster. It's real downfall is the flute setter, the cutting edge should be aligned with the flats on the collet holder or it will produce a point that is too wide in the webb. One down fall of the machine is the motor uses metal shielded bearings, if you don't clean it out enough then grinding dust will kill the bearing on the shaft end of the motor, I have the larger model of this machine and had to swap out the motor bearing, I went for a rubber sealed bearing this time as they hold up better to fine dust. With anything Chinese it's not perfect but with modified scales, drill setter and better sealed bearing you won't get a more accurate drill sharpener for the money.

🤔 Great testing and review, Todd. On the subject of sharpening drill bits, I had an uncle who was a master welder and he learned to hand-grind multiple facet geometry into his drill bits, which he swore were superior to conical ground bits. When he started out as a machinist in the 1930s, he sometimes had to work without electricity and he was always looking for any trick he could use to reduce the effort needed to drill steel by hand. He also claimed the multi-faceted bits would outlast conical-ground bits by a large margin. Sadly, hand-grinding of multiple facet bits seems to be a lost art, but there are modern jigs that make 4 facet bits easy to grind, like the DBS-22. I don't know if there are any that will do a 6 facet bit, which is supposed to be even better. It would be interesting to compare multiple facet drill bits produced with the DBS-22 with the conical ground conventional bits produced by the Drill Doctor and other sharpeners to see if what my uncle said was true.

[@CatWithoutAHat]

I work in a machine shop with an older guy (72 years young) who has seen and done everything in our industry. Owned his own shop for 30 years, and really only works now because he genuinely enjoy the craft. He regularly free grinds 4 faceted drill points out on everything from a bench grinder, to belt sander, even with our disc sander. Whenever he's doing it I always ask him to sharpen up a few of mine. The genuinely cut better than any result I've ever gotten, that's for sure.

Sanding disk on an angle grinder, or bench grinder works pretty good in my subjective opinion.

[@johnbelwell2461]

I've learned tricks to sharpen drill bits with a grinder but the results of one of these are very convenient and obviously more accurate and yesterday i was thinking about these only to find out your video today. Guess even the cheapest can help me out considering i ruin drill bits like they're nothing. One thing to point out is sharpening drill bits successfully is heavily based on their quality, usually it's heat from using wrong rpm vs material that ruins their hardness and even if you sharpen them they don't last, most times drill bits of better quality are more heat resistant because of their composition and cleaner metal alloys than generic recycled chinese ones so if you use them properly and sharpen them they can last forever as long you don't brake them. I appreciate a lot the effort you put in your videos, you are one of the kind.

[@ProjectFarm]

Thanks!

[@gregkimura5906]

I have to admit that I've never used a drill bit sharpener. I throw my dull bits into a drawer in my tool chest and the supply just keep growing. I've thought about getting a drill bit sharpener, but so far I haven't. So this video is great, because I know which sharpeners will do a good job and also how much I have to spend on one. The chart at the end is fantastic. I choose my budget and find the best sharpener in that price or lower. Another great video! Thanks for the hard work.

[@ProjectFarm]

Thanks and you are welcome!

I've had a drill doctor for many years. It works OK. There is a big difference in the quality of drill bits. My go to are cobalt screw machine bits, if I'm not drilling something really hard, then carbide. I now eyeball sharpen on a bench grinder, fast and close enough for most uses. Drills always make an over sized hole. Most drill presses are not ridged enough to do precise work. A mill will do better using power feed. Ream or bore to get closer. In the video the affect of "pop thru" as the bit exits can be seen as the rougher area at the end of the hole. Power feed will reduce/eliminate that. Great video as usual, Thanks

I had bought a Drill Doctor 500 at an auction, new in box. I didn't even try to use it until I watched this vid. My first few attempts were unsuccessful but I read and re-read TFM and practiced until I figured it out. Yesterday I sharpened my first expensive cobalt bit that was shot. Came out great the first time and I drilled out a stripped set screw in just a few minutes.

[@Infinitas3]

I have literally no need for a drill sharpener, but I will say as someone who has destroyed and thrown away so many drill bits while drilling out rusted hardened bolts, this has been fascinating to watch. I'm sure I could have saved a lot of money in the past using these sharpeners. Alas, with the advent of electric cars and a deadly combination of kids, I have no idea of energy to tinker with old car projects. But really enjoyed watching this while thinking of all the broken studs I had to drill out so I could finish putting the car back together on a school/work night.

[@ProjectFarm]

Thanks for watching!

[@StevieB8363]

Firstly: I love this channel. Todd does the testing that the rest of us can't afford to do, so that we can spend our money wisely. I'm sure he has saved tradesmen countless dollars over the years simply by showing which tools are junk. Secondly: I find it interesting that there was no Makita, DeWalt, or Milwaukee sharpener. Why are non of the big-name brands offering a tool that their customers would surely love to have?

[@TractorsNStuff]

It was my job as a child (apprentice) in the shop to use a bench grinder and sharpen the dull drills. It was actually a valuable time learning about sharpness, angles, and relief. But sharpening with a bench grinder, while possible, does not equal perfection. I bought a Drill Doc a few years ago. Awesome review! Thank you

[@ProjectFarm]

You are welcome! Thanks for sharing.

[@TheStrosso]

Thanks for including the Truper brand. I still sharpen my bits with a dremel and a home made jig and wondered how that bit sharpener would work.

[@ProjectFarm]

You are welcome!

[@billj5645]

Very interesting. I taught myself how to sharpen drill bits on a bench grinder very long ago while working in my father's auto repair shop. I doubted the ability of these machines to properly sharpen a bit, knowing the complex angles that are involved, but the ones that worked contained complicated methods of moving the bit across the stone, not just rotating it along its axis. Before watching the video I would not have believe that they would work but some of them did indeed work.

[@ProjectFarm]

Thanks for sharing.

[@beerdrinker6452]

You are a real scientist. I don't think I am smart enough to use any of these products, but I enjoy all of your reviews. Thank you.

[@patricklikesmusic1]

Bought the drill doctor a few years ago for work. It's been sitting on my tool box since that day. Glad I picked a winner, sad I never used it but I guess this is the push I needed to go sharpen literal years worth of dull bits. Thanks as always for the videos.

[@ProjectFarm]

You are welcome!

[@dennistennyson8856]

The Drill Doctor I had was an older model but it served me very well. I did a lot of 135 degree split point drilling in my work for the speed using drill jigs.

[@ProjectFarm]

Thanks for the feedback.

[@unintendedpurposes]

You did drill sharpeners 3 years ago and now have a new addition! I like that you do a whole new video as new improved products come along. It keeps the industry improving. Thank you for what you do. Would like to see an updated one for cordless screwdrivers comparing the Hart 4V and the Kobalt 4V. Also, i run a full time fabrication shop, so if you need someone to real world test tools for wear and send them back to you, hit me up. Ill pay half the shipping even. Keep up the good work.

[@ProjectFarm]

Thanks! Thanks for the video idea.

[@archstanton9206]

I have had a drill doctor since they supplied a VHS tape with them for instruction. I have had inconsistent results with it, the bits look textbook sharp when done but don't cut as well as I think they should. I appreciate this video, I need to lock myself in the shop with it this coming winter and sort it out.

[@ProjectFarm]

Thanks! Thanks for the feedback.

[@TheHighwayGroupie]

Thanks for the video. I have been using Drill Doctor for years. I love it! My only criticism is the lack of tips and tricks in the manual. Your video gave me a little more insight. Tip: on the 118°, if you advance it by one notch when setting the bit in the chuck, you get a slightly higher pitch and faster cuts. BUT, it also grabs a little more. Be careful. A good drill can twist your arm off when the drill bit bites!

[@ProjectFarm]

You are welcome!

[@hotratz69]

I've had my original Drill Doctor for about 20+ years now. I've replaced the chuck once and now it appears that there is other wear that make it time to replace. My original only did up to 1/2" but now seeing this review I am going to spend the money and get the 750. It might be expensive but I got over 20 years out of my first one and believe me, I did a ton of bit sharpening in those 20+ years. One of my favorite tools.

[@ProjectFarm]

First time watcher... long time blunt drill bit user... I've hemmed and hawwed about spending the $$$... but after this I just bought the DD750x... I dont use 19mm very often, but I've always thought the buy once cry once philosophy is best. The DD has a solid rep, been around for years, which means replacement parts should be easily available too. Just subscribed - look forward to going through your catalogue and seeing what else is interesting.

[@ProjectFarm]

Welcome! Thanks for watching and subscribing! Thanks for sharing.

[@StephenDanielAddeo]

I have a drill-doctor for almost 20 years and it has never failed me. Still works wonderfully.

[@ProjectFarm]

Nice!

[@haywire17]

I was given a Drill Doctor a few years ago. It has saved me a lot on 2' long "installer bits" that we used to simply replace when someone hit concrete with them. I have used it on smaller bits as well, and I've always been pleased with the performance. I've always thought it was one of the best machines out there. -- It's good to see that proved out by some comparisons.

Bench grinder and angle guides. You can get really technical on drill bits if you choose with back cut reliefs etc

I know this suggestion may not make a lot of sense at first but hear me out. I wanna see laundry detergent tested side by side. Especially for their ability to remove grass, dirt, and oil stains since those are so common in farm and shop work (blood and wine/fruit stains are also common measurements I think). Not sure if it is a good idea for views but it would be awesome to see what testing methods you could pull off and would GREATLY influence what I would buy in the future. Great video as always BTW!

[@ProjectFarm]

Thanks! Thanks for the suggestion.

[@larryjohns8823]

Have an old (30+) Black n Decker model 7980 sharper. I now see that it takes time to really get the bit sharp.😊 thanks Todd.

How are you doing today? I am doing pretty good myself. I just would like to say thank-you for getting to another one of my video ideas. I love all the great work and the great information that you have provided in the making of this video. I would like to see you try testing: stone chisels to find out which manufacturers are the best. I hope that you and your family take care until next time.

[@YodasTinyLightsaber]

When I worked at a machine shop and a drill got too dull, we had a 3 step process. 1. Order 1-2 replacements from our vendor 2. While we were waiting, try to sharpen on the bench grinder and finish the last few holes 3. Throw the bit away I think the Drill Doctor would have been a better option. Thank you for reviewing these tools. Your videos are the best.

[@ProjectFarm]

Thanks and you are welcome!

[@andrewgray7581]

Another great video keeping things honest. As an idea, what about hardening techniques after sharpening vs remaining just resharpened. I usually use a propane torch, to heat them, then slowly dip it in cutting oil to cool and harden it. Curious if there's a better method, or how that stands up compared to just getting a new bit.

[@ProjectFarm]

Thanks! Thanks for the suggestion.

[@farisal-salihi3780]

Another excellent review of drill sharpeners. I have gone through many sharpeners over time and settled on Drill Doctor as my favorite sharpener. Glad that you have picked the best.

[@vincenthuying98]

Have great experiences with the Drill Doctor. The split point option is a nice addition to an otherwise already excellent machine. Used similar less elaborate and cheaper drill sharpeners in the past. They never ever lived up to my expectations. Had been deliberating on the ‘Ainso’ or similar European brand some years ago, but even though the machine feel is great, for the amount of drills I sharpen each year, too great of an investment. The compact design of the Drill Doctor sold me. It can be easily cleaned, maintained and stored, where the Ainso is more like a stationary machine especially on the weight aspect. Added to that, I worked with the Ainso in a shared workshop, where it first wasn’t bolted down. After some lessons learned we permanently mounted it, which seriously improved its sharpening capabilities. Hence, the indecisiveness when I needed a sharpener for my second or third next workshop. Also, excellent and outstanding explanations on the different sharpening tools.

[@ProjectFarm]

Thanks! Thanks for sharing.

[@TheHayruss]

Awesome video once again thanks so much for your diligent testing of different products. A couple of suggestions to the testing and and assessment aspects of this test. I think using a cutting oil or any sort of oil to reduce heat would have been beneficial and I think bit durability (how long it stays sharp and cuts well) is one of the most important factors. Maybe 5 cuts in a row timing each one using oil might reflect using a drill press and batch drilling. Just my suggestions thanks again for an awesome video.

[@ProjectFarm]

You are welcome! Thanks for the suggestion.

[@stevebabiak6997]

A couple of other things to evaluate. Hole diameter and is it out of round. And since this is on a drill press, is the hole out of vertical, should be perfectly perpendicular to the metal plate being drilled. The uniformity of that metal being drilled might be a factor - thicker or thinner in spots leads to faster or slower times.

[@Kent-pb2jl]

I'm on my 2nd DD750X after the first one's motor wore out but after years of use. The diamond coated abrasive on the DD will last exponentially longer than those cheap grit wheels. Does take some practice to get them cutting their best.

[@ProjectFarm]

Thanks for sharing.

[@jbolty]

I have a drill doctor and have had some great results but have also had some terrible outcomes but I'm sure there is something wrong with how I was doing I'm doing it since I know it works. I have also struggled with bringing back bits thate were really dull or damaged but all in all happy with it.

Perfecttiming! I AM looking for a drill sharpener, I have spent many minutes up to a Hal hour trying to drill a hole in my metal fence…all of my drill bits are old and well used..so, I might have to bite the bullet and go for the Drill DR. I’ll check the charts and make the decision then. Thank You!

You are welcome!

[@mickjager5974]

I could actually use the Dapin pretty well if I turned it over and watched from the back side. Then I could see the cutting edge where it was hitting the grind cylinder. I also cut away the cross piece of plastic so my finger could hold the drill up against the plastic guide better. Was actual able to take a broken drill and redo a point on it, granted it's very short now! Went through and sharpened all my collection of crappy old bits.
