Using Drill Doctor To Sharpen A Drill Bit

I show how to sharpen drill bits with a Drill Doctor Drill Bit Sharpener. The model in the video is a Drill Doctor 750X. But the process is basically the same for the 500X. I bought the 750X model because I am planning to use it for sharpening some larger size twist drill bits up to 3/4". Too bad it won't go bigger, like up to 1" bits.
This is the Drill Doctor 750X that I used in the video:

Your instruction are better than the manufacturer RJ...! Outstanding Job ..

[@mooglemy3813]

Looked at drill sharpeners on KZbin on drill doctor came out on top. Looked at Amazon reviews, said look at KZbin reviews. You came out on top. Superb explanation and tutorial. I never considered split point till now. Just turned 72 and still going strong. You can always learn something new daily if you have a curious and open mind. A SC dude aka Butter Bean made the smartest statement I've ever heard.". Damn Y'all Know I Must Be Stupid Cause All I Do Is Learn". No arrogance or I know everything etc in that statement. I learned a lot from him and subscribe to that statement to this day 40 years later. Great vid again!

[@jamesrowe6389]

I appreciate the video, just bought the Drill Doctor XP and was looking for a good video to explain how to use it. Instruction was straight to the point and easy to understand. Now off the sharpen my dull bits.

[@waltp3373]

Concise and to the point. I just ordered a Drill Doctor this past week. It hasn't come in yet but I'm looking forward to using it. I used to sharpen drill bits quite well freehand by hand but I haven't done that in long time and my eyesight is not what it used to be so I hope this works well. Thanks.

[@trevorhughes5482]

Thanx for this! My grandfather passed a few years back and received ownership of the shop he built on his property and I use it all the time. We cleaned it this summer and I found the drill dr. 500x and knew what it was but not how to use it and this video helped tremendously so thank you!!!

[@shawnkim4598]

I love this video, I wish that more reviews was this informative,.... Don't know this tool that well always wanted one but you probably didn't left any thing out... Thank you and I really appreciate it!

[@somoninsam8807]

i just got a first Drill Doctor 500x today never use this macine before and i like to learn from you and your video big help for me Thanks you RJ

[@McGinnisArtistry]

Thanks for the review of the 750X. You covered all of he details nicely. I kept on misreading the manual and thought I needed the accessory chuck to sharpen 3/4" bits. But the 750X comes with that proper chuck. I have also had fun sharpening my larger diameter bits. And thanks for the tip on what the 135-degree setting would be good for.

[@edelmiroacostajr4715]

Best informative video on how to you the dill doctor. Great Job !!!!

[@geremykniffen8770]

Very clear demonstration of how to use this product sir.

[@aaronconwell7403]

Thank you mate. I just bought a drill doctor and didn’t have a bloody clue how to use it and the instructions are annoying. It all makes sense now. 👍

[@Annacats25]

Thank you RJ. I appreciate the video. It's easy to understand and follow. I have a business building chairs out of old wine barrels and I go through a lot of bits. Thanks again!

[@5x535]

The best demo/explanation out there that I have seen. Thanks RJ

[@waynesmith9765]

I bought the 750 about ten years ago and have watched several videos including this one. If your drilling wood, plastic, or aluminum it kind of works. I have yet to see it work on hard steel. I have had at least a dozen other people try it and no one who has tried it wants a drill doctor. It doesn't work in hard metals. That's to bad because it would be super handy.

[@vegasurbutis669]

absolutely agree .waste of money!!

[@stewartmcmanus3991]

Me too, waste of money, could NOT get it to put relief on the bit no matter what I tried. The heel always ended up higher or level with the cutting edge. Can't do free hand any more, poor eyesight. Don't waste your cash.

[@johnburton9156]

[@deliciousgroove]

Well done. I just bought a Drill Doctor. This helps. Thanks.

[@TheErnieeeb]

Thanks good job. I am now in the market for one. My grinding wheel leaves something to be desired.

[@matrix64]

Good job RJ. We all appreciate the good and clear demonstrations and close ups of the before and after sharpening. Thank you.

[@UpInYourFeelings]

well done. Much better than the instructions and video that came with it. I have the older model which doesn't swivel like that but after watching this I'm gonna get it out of storage to try again.

[@flor.e.cultura]

Another great video another great tool!!!

[@josephmyers1492]

Best demo i've heard. You got my subscription.

[@MONTES262011]

Serious good video bro thanks!!!!!!!

[@studegator]

I've owned a 750X I bought new for 5+ years. I have never succesfully been able to make a split bit without the cutting/grinding wheel taking the new edge off when pushing in to make the split. Just tried it again after viewing this video on a 7/32 bit. Same results, sharpen the bit, then try to install into the split bit hole and it grinds the new edge off as well as the back side of the other one.

[@californiamechanic5593]

Thank you for your help.... from California mechanic

[@georgehatz5927]

[@Goldnugget47]

Thank you so much I've had the drill dr. for years couldn't get it to work, I believe now I can, subbed for any up dates.

[@darrellbullard1301]

I have had one for a long time but didn’t know how to use it. Thank you.

[@jamesbradbury8332]

This video is much better than the factory video. Thanks for a great job

[@almc-wi5vo]

Once I saw this, I ordered one. Great investment. Thank you

[@richardcranium5862]

Thanks for this video. I picked one of these up at a yard sale but it didn't have the instructions. I work in a fabrication shop and the owner is hell bent on only using a grinder that has a wheel that's probably older than I am and doesn't have a flat surface on it. I'm sharpening every drill bit in that shop tomorrow.

Are you going to do another bike riding video, like one that you descended down a mountain. Great video by the way🚲

[@RJTheBikeGuy]

Maybe sometime. Nothing planned.

[@lucianonarno1408]

Hey RJ, kind of a personal question: do you also ride a lot? Im into both things, fixing bikes and I ride about 100km a week, sometimes more.

[@RJTheBikeGuy]

I run a lot more than ride. I do ride though. I have a few race/riding videos on my channel. I just rode the nearly 40 mile Black Fly Challenge Mountain Bike Race a few weeks ago.

[@rhysbourke9077]

I used a sharp bit to begin with and it came out just like his (1/2 blunt) iv'e done t in 3 types of sharpeners all the same result

[@RJTheBikeGuy]

I don't know what is happening as I had no problems. Maybe you are doing it wrong.

[@neilfroggycrompton2466]

hope u can get replacement parts for it when the plastic parts wear out,another great video :)

[@dhansel4835]

When I purchased my Drill Doctor they told me if I need it fixed it would only cost $ 35.00 and everything would be replaced that is worn. It's a great tool !

[@Wedelj]

$35 rebuild? Nice!

[@dhansel4835]

It's well worth the price. Drill bits are expensive, especially the good ones.

[@rski1036]

There are no plastic parts that will wear out.

[@user-td1zo3tv9p]

Has anybody actually WORN OUT their DD? If so, what specific parts "wore out" or were they broken due to mishandling or carelessness? Also, if parts actually DID "wear out," how long did the part or parts last? As in how many drill bits were sharpened before something let go, shit the bed, imploded, etc.? I can appreciate that moving parts will wear due to ongoing contact (unless they were made of hardened material) but if the machine was able to sharpen, say, 10,000 PLUS bits, is that an acceptable number before said parts became so worn that the original tolerances were no longer met? Now if the tool or parts were worn out after only, say, 20 or 30 bits, then yes I'd say there was a defect or the worn part(s) didn't pass muster for durability and should be taken to task. But considering ANY component that rotates or has repeated contact, "wear" can be expected and anticipated, much like you'd expect from car tires, fan belts, bearings, etc. I would expect that rotating parts like the cutting device WOULD wear out after repeated and continual use, but that is their purpose and should be considered as "sacrificial" to some extent. So buying a spare grinding wheel (or spares in differing grits for stouter grinding needs) or other user serviceable components might be a good idea to have on hand if you expect to use this on a regular basis or over many years. Now if the motor that does all the hard work fails and requires replacement, you never know what the life expectancy will be. A lot of that kind of variable is dependent on the manufacturer and whether or not parts require periodic servicing to lubricate or remove debris to prevent gumming up the works, as it were. Also, if parts are purchased and assembled from outside vendor sourced parts, did the original manufacturer use QUALITY components or were they obtained from the lowest bidder? There are a LOT of variables you have to take into consideration in ANYTHING you buy. Inquiring minds wanna know. ;-)

[@justingiovanetti]

Does this work for concrete bits?

[@RJTheBikeGuy]

kzbin.info/www/bejne/qXrRmp1_ZtulaZY

[@user-qx1zt8mq4q]

So this might be a dumb question but do you sharpen a left handed drill bit the same way or is a completely different process ?

[@transformer889]

I have this unit, it works ok for large bits , but any thing under 1/4 try to take as minimum as possible, the tool is not very accurate for small bit

[@robertthomas6127]

$250 for the Drill Dr and $50 for replacement grindingwheel .... Nice toy for alot of money. I'll continue grinding my bits by hand on my benchgrinder and they are just done just as well, possibly better.

[@mback12000]

it's half that price on Amazon

[@ManojVarsani]

Good one, but what about 1 inche and 2 inch drill bit?

[@user-td1zo3tv9p]

Manojkumar Varsani, I think that for the purposes of this generic video, the DD presented is likely aimed at the DIYer type and (perhaps) a small shop that doesn't mass produce parts for world-wide sales. To that end, and to address your original question, I'm of the opinion that the typical or "average" user of the DD line of tools rarely (if EVER?) would have need of drill bits as large as you mentioned. When you are discussing a bit of that size, one would likely associate them with a larger manufacturing concern and, as such, would acquire a machine of much heftier construction. But if, in fact, a DIYer did need a bit of said proportions, it would be of light or intermittent need and I wouldn't think a bit of such magnitude would be used enough to dull said bit or bits on a regular basis. Just my $0.02 worth on the idea but YMMV. All that said, and in the interest of curiosity, I, too, am interested in what kind of tooling would be required to sharpen them outside of an industrial need. Anybody have a good answer or idea?

[@julienbouchard3048]

The threading on the fork of my peugeot started to get destroyed and the whole front part of my bike is loose. I dont really have the money for a new fork is there anything i can do to save the one i currently have?

[@RJTheBikeGuy]

I really don't have any good suggestions for stripped fork threading. Sorry.

[@2high2flyfpv88]

I just bought a brand new drill doctor and it just grinds the point off the bits. Got it set at 118 and watched a few videos on how to use it but it just ruins every bit I try to sharpen. I guess I must have got a lemon. There doesn't seem to be much to using it, but mine is just crap. Looks like it'll be going back to Lowes.

[@jca65lb]

"Having a lot of fun with this"? Man with simple needs😂. Jk, nice video, thx.

[@kevinkall8547]

what about sharpening the side edges along the shaft? don't those also wear?

[@DrFiero]

You don't drill with those though. Just the face. If you were using a milling machine with an end mill... different story.

[@charger440]

Sharpening with coarser wheel will go faster but, with a finer one, the drill bit will cut better!

[@BC5391]

your dull bit is sharper than the ones I sharpened with the drill doctor

[@RJTheBikeGuy]

It sounds like you are doing it wrong.

[@billgarrison1724]

sorry how do you sharpen broken bits

[@transformer889]

Great instructions, drill doctor works very well for large bits but anything less than 1/4 not so well.

[@josephpugliese9615]

I've seen guys sharpen bits on a grind wheel in seconds. Tried to learn it myself but I just can't seem to get it right.

[@nicatnicat1918]

👍👍👍

[@kempaswe4022]

With some training you will shapen drills better manualy on a grinder. Tried one of these but I make it faster and better without these. Been grinding manual since the 90s

[@gatorwing6231]

Here is a tip some may find useful. The machine can't read if a drill is chipped or out of shape. It can only polish what it sees when against the striker or anvil. Grind off a few thousands of the tip point with a regular bench or drill grinder and reinsert the drill bit against the anvil. Let the alignment paws grip the drill and continue as usual. You have just tricked the machine and totally new cutting flutes will be the result. I do it with most drills but the instructions won't tell you this trick. Problem solved. GATOR

[@rhysbourke9077]

I know you have only done the theory in your head..!!! Common Sense would make your theory practical but you may off missed the part after the the alignment caws where it sets the depth of material to be removed??? I didn't try with the grinder tst i used a sharp bit to begin with and it came out just like his (1/2 blunt) iv'e done t in 3 types of sharpeners all the same result

[@gatorwing6231]

@@rhysbourke9077 You are obviously not paying attention. The alignment paws in the video are only gripping the flutes on one side because the drill is in bad condition. Grinding a couple of thousands off the tip lets the paws grab the drill using both flutes for proper alignment. The paws have nothing to do with the depth of material being cut but instead how aggressive material is removed per rotation. The paws set the rotation angle so the cutting angle on each flute is equal. The adjustment screw on the stopper determines the cutting angle of the flutes allowing different aggressiveness of the drills ability to remove material per revolution. You can observe that the finished product in the video cuts through the metal but the chips it removes are not like a new drill. You don't want either powder or different shaped fragments as that is a sign the flutes were not cut properly (nothing to do with the tip angle). An improperly sharpened drill makes a hole but not uniform in shape. I think you were daydreaming or lack experience. No I haven't only done my theory in my head. I have owned a machine shop for over 30 years. LOL

[@pauledwards7182]

A properly sharpened bit, steady speed, pressure and cutting oil. It should be like a perfectly pealed apple(one peel).

[@gatorwing6231]

That would be true on soft steel and aluminum however cast iron looks like powder and hard steel like chips. On most steel I use cutting oil however WD-40 works best for me on soft metals like aluminum (A tip from "This Old Tony's" channel that works well).

[@gremlin7599]

Why are there two different holes to shove drill bits in

[@bobmccann2141]

It seems to me that this product can work! And work very well! But when you do not understand and or read the directions, you may not get good results. Many of my wood working friends are split about this product. This also tells me whom reads the directions, and who just starts in and hopes for the best.....

Funny to here all these haters about the drill doctor.. Obviously, they do work. Seems like these people just can’t seem to follow simple directions..

[@anthonymelendy4612]

Cool tool . I am a retired carpenter and could have put that sharpener to good use . I've always just sharpened the bits on a bench grinder . Sometimes they be sharpened perfectly and other times not so much . If I could offer some advice it would be not to drill aluminum like that without clamping it down . I realize you were making a video but a small piece like that could have started spinning around .Especially if it were to climb the bit when you went all the way through . Trust me as I have learned the hard way and smacked my hands several times cutting corners . When you get ribbons of aluminum like that it tells you that the bit is sharpened good .

[@RJTheBikeGuy]

I could have done it on my drill press, but didn't feel like moving my wife's car, and dragging everything out there.

if you buy a good drill set made in US, $200. it will last 10 years. Sharpening not required if cutting wood or mild steel.

[@oldsloane]

I read the directions over and over, I watched the how to's on youtube and I still could never get as good a result as I get from hand sharpening. Not worth the cost in my opinion. I gave mine away with the sale of another tool.

Because it's overpriced junk...for idiots...
