Stefen - You did an excellent job reviewing and demonstrating this machine. The manufacturer should reimburse you for your efforts. Thank you so much for sharing this with your followers.

Thanks Stephan for all your videos over years. I've learned a ton watching. Now, just in case I can offer a microscopic something in return, at 23:27 you say "Lead way". I think you want "Lee way", a nautical term meaning you have room downwind to maneuver. Or you have room to maneuver in whatever thing you are doing. Thanks again!

I bought (6) sets of 115 drill bits over time, because I could never find the right drill in the box. This went on until I bought a drill set that was so expensive that I would put drills away back in the box. After I built up the good habits, now I can use the cheap drill sets.

[@ydonl]

I was honestly surprised that you liked this machine! I knew you would think about it, so your review is helpful.

[@alexwbakker]

So, it's like an *actually good* version of a drill doctor. nice.

[@zachaliles]

I remember the first time I ever saw a drill doctor. The shop thought it was the best thing since sliced bread. All plastic, the setting was janky at best, it never seemed to want to spark out, the collet never held the bits very well. We tried to use it for a little while but went back to using a bench grinder pretty quickly. It was a good idea but the execution was trash. This thing looks great and seems to do a good job. Better than I can do on a grinder free hand.

Stellar review Stefan!

[@TheWidgetWorks]

I have a similar unit and the larger version that goes up to 26mm which covers anything I would need for a twist drill. Also I have a diamond wheels for them so I can grind carbide drills. Works good but it is a bit of an extra step to switch the wheel out but it's not over time consuming.

[@StefanGotteswinter]

Cool! It seems like the bigger machines are rarer, not so many seem to be around. I might get a diamond wheel at one point too.

[@2lefThumbs]

I'm glad you did the full video Stefan, thanks- also glad you gave the price 👍👍. At the rate I blunt (HSS) drill bits, it's far cheaper for me to buy 5-packs of common sized drills. If I used more costly cobalt or carbide drills it would make sense for me to buy something that gave results like this with next to no skills needed. 👍👍

[@HP_rep_mek]

Great review and a nice machine there Stefan👍

[@greglaroche1753]

I just watched the video on patreon but couldn’t comment there. I’ve been contributing each month, but there must be a glitch somewhere. Anyway, I’ve been using the newer model of Drill Doctor for several years now. It not near the precision machine like yours, but it does a good job for what I paid for it. It has the option to split grind the tip, but I don’t bother much using it. I always pre drill and don’t see the need for it. I guess in mass production, you could save time, not having to pre drill. Also, to get a perfect hole, I thought you should always follow up with a reamer. I always enjoy your videos and have watched most of them several times. Especially, on the Deckel FP1. What a great machine ! Thanks for all the great knowledge you are offering to machinists who are beginning.

[@heinrichhemker8123]

Thank you! Absolutely excellent!

[@markmuranyi9289]

Stefan. Nice drill grinder. I am accustomed to a Darex SP 2500 which I used in my day job. I am retired now and have looked to purchased one maybe off ebay, but their prices were out of my price range and they looked pretty beat up. Thanks for posting.

[@kmpnelson]

Awesome! I've got the same one so watching someone methodically go over it, and hopefully make some upgrades I can follow will be great! And I'm first!

[@firstmkb]

Stefan, another difference I noticed on your pre-drilling demonstration is how much hotter the second hole was. The amount of steam from the coolant surprised me, but you must have expected it due to your experience.

[@cmguitar50]

Very nice! The non pilot hole vs pilot was an excellent comparison, and the machine looks nice and robust. I have a Kuhlmann grinder and will watch your video on grinding drills with a D bit grinder. I can't justify spending the money for a dedicated drill grinder.

[@Smallathe]

Cool tool. In a previous video you recommended a cam drill press vice. I just got mine - thank you so much for the wonderful tool tip. Much appreciated - I'm hooked! :)

[@StefanGotteswinter]

Yay! Good to hear :-)

[@myradavis2599]

Thanks, excellent tutorial

[@bruceanderson9461]

I have a Darex which does a very nice job from 1/8 to1/2 inch. The wheel must have finer grit as the grind looks smoother but it may not last as long also. Dust collection is a very nice addition which I have as a dedicated Darex vacuum.The Darex is 2 to 3 times as expensive but I got it almost like new from a fellow hobbyist who past away. It is wonderful to have sharp drills in a minute. Once you have one of these machines you can’t go back to dull drill bits. Good purchase for your shop!

[@JanBinnendijk]

I used to use a Darex M5, and i thought it was a wonderful piece of kit, i could also make Helical points on that machine.. as well as 3 Flute Drills. This Motom machine looked like a "Drill doctor" to me, but this one actually works!..not too bad..

[@JustinAlexanderBell]

@@JanBinnendijk Drill doctor works, just finicky.

[@JanBinnendijk]

@@JustinAlexanderBell I used a Drill doctor once.. too Finicky.. just no good.. i ended up teaching all colleagues how to sharpen a drill by hand.. way faster and better.. i told my boss to throw that drill doctor in the bin..

[@jonathonschram3429]

@JanBinnendijk We have one of the better/higher end drill doctors at work. I think its pretty handy for bits under 1/4 or 3/16...but we all pretty much free hand anything larger. Couple guys just don't seem to be able to grasp how to sharpen drills, so I think they use the drill doctor for everything regardless of size. This machine looks about 1 million times better than the drill doctor though. I might have to look into getting one for our shop. It would probably pay for itself considering how many bits we go through each year.

What a coincidence Stefan. I did a review of the Vevor drill grinder two weeks ago. Same experience: One trick pony, but grinds drills back to factory specs in no time. It was nice that an extra diamond wheel was included with the Vevor, great for carbide.

[@nocturnhabeo]

Seems like one of those things that you never really feel like you need but if you have one it just instantly turns into a minor part of your day which you could never live without

[@firstmkb]

I stopped the video in the middle to check out pricing because I don’t make any money with tools. The Vevor came up, and seemed reasonably priced. Then I saw a similar machine listed on AliExpress for $35 and change! Plus $235 shipping. 😢 I want to buy one TODAY but am going to wait to see if I feel the same way in a month. Or run out of patience!

@@firstmkbthose aren’t the same machine. There are a number of “similar” machines on the market. If it’s a lot cheaper, it’s a different tool.

Thanks

[@MyTubeSVp]

I have the same machine (different brand and color, 1/3 of the price, but clearly the same manufacturer or at least design) and after a lot of trial and mainly error, I found my guessometer has to be set at drill size + 3mm. But apart from that, it’s a dream to work with! I used to sharpen drills by hand for 40+ years, and was pretty good at it, but this is an entirely different category of precision, sharpness and usability.

[@jefferywright4204]

What is the brand of your drill bit sharpening machine and where did you purchase it?

Lots of makers, with different precision and pricetsg. Also some variants of the trick they can perform. Four facet , flat bottom etc.

More collets, I bet Stefan has got collets on his tooth brush and gas cap. I knew before hand it wouldn't be cheap, but he's only buying it one time and over a lifetime it will work out to be pennies a drill, whereas coffee and a donut is almost $5 bucks now.

[@brenwyattm0rij909]

Great video Stefan, I will add this to my Saved List due to fact I have one of these machines or very similar in my shop which I will look at tomorrow. Do you think there is much of an advantage drilling with split point with a pilot hole? Would be good to see holes drilled with both split point and non with and without pilot holes. I think that came out correct ??? Anyway thank you.

[@Brrraaack]

Moin Stefan! Knorke device! Thanks for review. Finer wheel + less material removal could make this even nicer i think. Whats your feeling how well this will handle carbide drills?

[@thedabblingwarlock]

Neat little machine. Not all that surprised by the price (was expecting worse honestly.) There's a masochistic part of me that wants to see how hard it'd be to make one. Thankfully for my sanity, I don't have a shop to put machine tools in much less the tools to make the attempt.

[@bbbnz50]

Thanx for vid

Very good, I’ve been thinking about getting one. The only thing that’s stopped me is that the largest size is too small. I need 3/4” or 20mm.

[@dreamcat4]

being on such tight budget, i could never afford this. but then again the level of precision i end up having to work with is really poor for so many other reasons anyhow! (like not having a machine shop, etc). so for 20 bucks i just bought the budget amazon drill bit sharpener that was recently tested and recommended by project farm. which of course maybe not as professional, but at least i can then afford to buy other more urgent tools instead for those monies saved. still very lovely video, and to show the demonstration with and without reaming. for example i can buy some m35 cobalt bits (5%) in the 0.1mm increments (from local uk supplier here). which is affordable to me. and then consider for doing the reaming and also the centre drilling / pilot drilling. which isn't too expensive or anything. and with a good accurate markup tools for centre punching etc. it can be good enough for my home hobby and diy purposes. at least 'as good as can be' without proper machining tools for lathe, mill etc. anyhow love your videos and i watch since long times, ever since you got the emco lathe was how i found your channel. just such useful and helpful things here. so grateful many times already. best wishes my friend

Hi. Does main grind movment have ball bearings or plain bearing? Vertex vdg-13A has plain bearing and it developes bit of drag after few drillbits. Needs frequent cleaning.

[@CatNolara]

That tool looks very handy Does predrilling also improve the precision of the hole location or would it be more prone to wander off?

[@StefanGotteswinter]

Hmm, I "think" that it does kinda improve hole location, since you dont have to force the chisel point trough the material.

[@zachaliles]

And if you were really in need of a pedestal mounted sharpening station I'm sure you could build a stand for that machine.

[@SonOfMrGreengenes]

In my opinion a modified General no. 825 bit sharpener is best and can produce factory quality drill bit geometry. I should make a video on the modification process.

[@gearloose703]

The common design is dc motor and rectifier (thus it can be coupled with speed controller). With some practice drill grind depth is easy to set by hand and the orientation by eye. And practice there will be... For small drills (under 3mm or so) the stickout is too long. They vibrate and can not keep any tolerance. The chinese ones are good. Well worth the 300 or so euros.

[@wktodd]

The brierley we have at the works does everything but is so complex to setup no one knows how to use it :-) That looks a better option for drills

[@wktodd]

@@crozwayne no it isn't hard to use just complex , if only used occasionally, it needs s refresher course.

[@OstapHelDesigns]

Thx for a great video! 👍

[@SonOfMrGreengenes]

The flank (the part of the surface that is ground) looks faceted. Taking into consideration the way that the holder rotates and operates I'm puzzled as to why the flank would be faceted. If it is faceted then that's not good and can cause there to be a need to increase the clearance angle for the bit to function properly. I do understand that the split point option will negate some of the faceting but II believe not all machines include the split point feature.

[@bertblankenstein3738]

Sharp drill bits make a big difference. I'm not a machinist. Was drilling through some stuff recently, got partway through, switched to another bit and that went through WAY faster.

[@ChazzC]

Thanks, Stefan; a good honest review. I like that the machine is all metal and has "calibrated" adjustability. However, I think I will remain satisfied with my Drill Doctor. While it is a combination of metal & plastic (mostly FRP), has a single chuck that accepts the full range (3/32" - 3/4" | 2.4mm - 19mm) of drill bits and does not have the capability of doing web-thinning, it can create points from 115° - 140°, has adjustment for material removal (so you can "touch-up" a bit that is slightly dull), has a split-point port (with a suction adapter that fits into the split-point port, which is OK since must of the dust is generated while sharpening) and for the $US130 I paid for it in 2014 ($US170 currently) it does what I need for my mini-shop. The bits I have sharpened cut evenly and cleanly. The standard grit wheel is 180G, with an 80G option available for faster material removal on larger bits. There are also aftermarket wheels available in 120G & 220G. All of the wheels are diamond plated. The Drill Doctor comes with a good pedigree as it was designed by and manufactured by Darex. Thanks again and stay safe, Charlie

Though likely adequate for sharpening drills, how is the clamping pressure and distribution when the collets are backwards?

[@StefanGotteswinter]

The collets work practicaly the same way as in an regular collet chuck. A little less contact area on the shorter taper section, but in my experience thats not a problem, since the collet is only tightened by hand anyways.

[@mjshorty19]

Man I've drilled probably 100s of 1000s of holes with hss jobber drills never prefilled one time under 18mm diameter and as long as it's not running out they always cut within .001 (.025mm) of nominal size

[@be007]

this is a good and honest review. I have the same grinder but from HBM. I paid 199 euros for it, it was discounted, normal price is 349 euros. I wonder if there is much difference in quality between my HBM grinder and your Motom grinder? personally, I don't think there,s much difference. cheers ben.

[@timogross8191]

There are differences for sure, I know that from testing different makes and models at machinetool exhibitions. The alignment of the wheel is off for the webb thining on some machines. Sometimes the wheel wobbles. Some machines come with finer step collets default. The fit between the grinder and the drill bit holders can be very different, drill bit holders can be very different in fit and feel, with the collets. The alingment jigs have variations: hardness, fit of the drill holder, laser engraved dials (stickers that can be wiped off with Alcohol 😞😲), correct placement of the dials. Some come with a separate alignment between rotation and length, wich makes setup for small drills (smaller 3 mm) much more reliable. Some have a magnifier with cross hair to align the drill. My below 300 USD device works "sort of" but is rubbish for small drills. A unit for 3x the price is much nicer to use and can go down to 2mm drill size. I had to pay for the CBN wheel extra, which comes default for some machines. Hope that comment was not too longwinded. Similar ponies are available for other tricks e.g. Wood drils, 4 facet grind, sheet metal point etc. Also a nice alternative for the people who do not want to spend several hundreds on the machine kzbin.info/www/bejne/d6uznKCXa9F3d9E

I would like to place a stupid question here. Can this apparatus sharpen parabolic drill bits?

Very reasonable question I would say - I have sharpened some parabolic flute drills and they look very odd after grinding, but they seem to cut ok - But its not the original grind.

One thing I don't like about this design which has been copied everywhere is it blows the grinding dust into the shop and everywhere.

Have you considered investing in the other similar machines? I know from my looking at these there are tap and endmill grinders available from the same offshore manufacturers, I looked into them somewhat but couldn't find much as far as I would consider end user reviews so never picked one up. I'd also add, I would gladly watch your honest tool reviews, though I understand that isn't the direction you may want to take you channel HOWEVER, I believe that a lot of us would be willing to watch reviews that are honest and benefit your channel.

[@StefanGotteswinter]

Looking at the stats of my videos, the best for my channel would be to do ONLY toolreviews and shoptours :D Those get the most views and engangement. But as you say, thats not where I want to go, I want to convey a certain degree of knowledge to those who watch my videos. Thats also why I can not really justify one of the other drill grinders in the same style/different name to draw a comparisation. But if you look up other peoples videos on these and compare it to this one, I hope you can make out some suddle differences. I have seen that the stop pins on the web thinning and split point positions are roll pins on the cheaper ones, on the Motom they are nice solid pins. Much difference? I do not know.

I've seen s few reviews of the chinesium (Vevor) version in yellow, would be interesting to see a comparison

[@StefanGotteswinter]

(I am not buying anything from Vevor) - I guess watching this video and a bunch of reviews on the vevor would give a decent idea of how they compare.

[@mrbrookes84]

Yeah I have one, not from Vevor but a UK supplier, they all look pretty similar. Not as nice as the Motom one but also a fraction of the price and plenty good enough for my needs.

[@Paul-FrancisB]

@@StefanGotteswinter 🤣😂 letting Vevor into your workshop is probably against some sort of international law.

[@MyTubeSVp]

Vevor has pretty decent equipment for hobbyists. I bought one of their vises and am pretty happy with it.

A few steps up from my potts..

Q: Must say you stared an need of a new workshop skill. :) Any chance for a film about sharpening small drills - less 2 mm ?

[@carlhitchon1009]

I think most people just buy new ones.

[@sblack48]

I don’t see this model advertised anywhere except from German vendors. Is it called something else in the rest of Europe or North America?

[@sblack48]

Btw I see it’s still stock or cutting tools 1 Stephane’s fingers 0! 😜
