I have used other methods to sharpen drill bits during my 37 years as a Mechanical Fitter, none can match this machine. I sharpened a badly worn 8mm cobalt drill bit in less than a minute. It drilled through 3mm mild steel in 9 seconds. A new factory sharpened 8mm bit took 13 seconds. After drilling 64 holes through 5mm mild steel plate with the used 8mm bit I tested it again and it drilled through 3mm mild steel in 14 seconds. This tool is well made and feels like it will more than stand up to the rigors of a fitters workshop. It's not cheap, but it is worth every penny.

Good machine to sharpen drills. Way better than drill doctor: better diamond stone, more precise, better motor. Delivery from Vevor was fast, no damage

Well made sharpener. Relatively easy to use. Does generate a very fine dust. Has a port on the base that could be connected to a vacuum source but not discussed in the manual. Learning curve is easy. Just remember to clean after every half dozen or so sharpenenings. Very quiet machine. Uses ER20 and ER25 collets. Comes with both the ER20 and ER25 chucks. Wheels should last a long time. Tolerances are tight. Definetly a good purchase.

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.

facile et précis d'utilisation. Très bonne qualité d'affutage quelque soit de diamètre du foret. La machine est compacte et peu bruyante. la meule est en en achat de dimensions standards ce qui est bien pour la durée de l'affuteuse.

La afiladora es genial. La he probado con brocas desde 2mm hasta 13mm con diferentes ángulos. Con la métrica 2 hay que ir con cuidado, a la hora de posicionar la broca. Yo conseguí afilarla. Los afilados son espectaculares. Muy precisos y la segunda opción que tiene la maquina para hacer un rompe virutas para facilitar el corte, sencillamente, GENIAL. Muy contento con la compra de esta máquina afiladora de brocas.

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.
