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.

Prix très compétitif. Très facile d'utilisation. Nombreuses possibilités de réglages. C'est un achat que je ne regrette pas. Possibilité d'affûter les forets au carbure avec la deuxième meule fournie. Le seul bémol serait le manque d'explications sur le réglage de la dépouille mais le réglage d'usine semble bien fonctionner.

Macht genau was es soll, wiederhohlgenau werden auch rundeste oder verschliffene Bohrer wieder scharf. Allerdings muss man schon einige Bohrersätze einsparen um den Preis raus zu haben. Aber nachhaltig ist es allemal. Daher trotzdem meine Empfehlung.

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.

I am very happy with the machine, it works incredibly well, I am taking it to my school to have it demonstrated, really good product, I am happy

Der Preis könnte etwas günstiger sein, die Qualität ist jedoch absolut in Ordnung, das Gerät ist wirklich einfach zu bedienen. Auf Dauer werden Bohrer sicher deutlich länger im Einsatz sein, als bisher, ein manuelles Schleifen wird überflüssig. Ich habe inzwischen mehr als 20 Bohrer aufgefrischt und bin mit der Bohrleistung absolut zufrieden. Was die Dokumentation betrifft, würde ich mir wünschen, dass die unterschiedlichen Geometrien von Bohrern und deren Einstellung am Gerät beschrieben werden. Bisher konnte ich nur HSS erfolgreich und problemlos mit den vorgegebenen Einstellungen schärfen. Weiterhin wäre die Dokumentation in deutscher Sprache für viele Käufer entscheidend.

great machine. takes a little learning curve but after you do its sharp drill bits once again. cutting two curly chips and accurate hole size. great value

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