Nagyon jó, ajánlom mindenkinek.

It took me a week or so to sit down and try to figure out how to setup and use the drill sharpener. The instructions are terrible. I ended up watching YouTube videos and was able figure things out. The hardest part is setting up what's called "Web Thickness" I believe. Once I got that straightened out the sharpener did an outstanding job on my drill bits. As of right now I'm extremely happy with my purchase!

Guter Artikel und top Preis

Good quality tool. 5 plus for sharpening drills. For example, drill size 8.6 mm and the hole after drilling is the same 8.6 mm.

I cannot believe how good this machine is. It works so well it’s like magic. My only regret is that I didn’t opt for the larger one. All my friends are envious except that they use it as much as I do.

It is the best sharpener I've ever had, never mind jigs, doctors ect. When sharpening I am trying to imitate factory shapes. As I understand the machine they use at factory is about $7000 or more so $250 MR-13B does the job for its price. Yes instructions are not brilliant and I would like to read some directions how to adjust the depth of split point. I do not like the angle it splits the web point and the blur it leaves on cutting edge, the grinding wheel could be bigger and finer, but hey as is it works great!

Works great on sharpening my split point cobalt drills.

Really good unit. Puts a really good edge on drills and repairs broken bits with ease. I wish it would do up to 1" bits.
