Excellent product. I have sharpened many bits already and they come out better than the factory sharpenings. This is by far an excellent product that will save you money and easily drill holes. Would buy again and would certainly recommend.

Easy to use. Works great. Smaller bits are a little harder to get right, but it's much easier than anything else I've used.

Bonjour. Je me suis permis de le démonter, (le bloc noir de l'ajusteur pour la longueur a aiguiser et le boitier orange) a la réception. Je me suis apercu que les collets: 2-3 3-4 et 4-5 était différend en hauteur, ce qui fait qu'ils sont enclin a tomber de leur localisation et qu'au moindre choc les huit autres font de même. Je me suis donc sculpter un bloc de styromousse avec des ouvertures de profondeur correct pour chacun, que j'ai ensuite coller a l'intérieur du couvert avec deux petits crochet en laiton de chaque coté sur le dessus ( suggestions a implanter ) pour retenir le couvercle fermé. J'ai aussi ajouter une pochette de dessicant ( dessous le double fond du support des collets) que j'avais récupéré dans un autre envoi. Je suis très satisfait de ces améliorations. Pierre

Have tried a couple of DD sharpeners, tried by hand on a grinder. Nothing worked well until I bought this sharpener. Its a little pricer than some but it works. Well built, nice design. Very consistent, makes a nice split point sharpened bit. Near fool proof, even for me!! Highly recommend.

I have 3 systems for sharpening drill bits, and this one is now my It beats them all in speed and ease of use, and ties one for sharpening accuracy. I have found it beneficial to put some light machine oil in the bores that receive the chuck. The instructions could be better, but once you figure out dialing in the bit rotation so it is perpendicular with the lines on the collet holder, you will get good results. I used it to sharpen centre drills with great results. I have managed to sharpen bits as small as 1/8" and the result is surprisingly good. However, it does take a little more time to orient the bit in the chuck, but it is certainly doable. So far I am very pleased with my purchase.

I have tried other drill bit sharpeners. I find this to do the best job. It also does large drill bits. I have drill Dr i find it to be inconsistent. This sharpener is my go to sharpener now.

I own a D.Dr 350X and a 750X. This Vevor MR-13A blows the other two sharpeners out of the water. There are lots of YouTube videos on how to use this sharpener. You will have precision results on the first bit you sharpen. The MR-13A does a superb job of grinding split points if you like to use 135 degree grinds for stainless steel and hardened steel. You can adjust the grind angle from 90 to 140 degrees. I use a 118 degree grind for most of my drilling needs. Although the collets are sized in metric units, they work perfectly on Imperial sized drill bits. I have sharpened over 400 drill bits since I purchased this unit. There is no wear on the CBN grinding wheel at all. I wish I would have known about this sharpener before I spent money on the other machines I had bought. I am totally impressed with this unit. BRD Feb 2025 Update - the sharpener continues to run and operate smoothly. I have sharpened many hundreds of additional drill bits for family, friends, neighbors. Everyone is impressed with the quality of the sharpened bits. This machine has been one of the better purchases for my shop.

This sharpen is absolutely a must have. I sharpened drill for 4 days all of which varied in length. This thing worked beautifully. All my bits are sharp as the day they were new. Great buy.

It works great and very easy to use makes a perfect shape bit Make it sharper then new I would Recommend it to anybody
