Szlifierko-szlifierka do ostrzenia Szlifierka MR-13A Ostrzarka ф3-ф13(15)mm

Very quick delivery. Easy to use once you've sharpened a couple of drill bits. I did have to read the instructions a couple of times before I got it. I'm impressed with this sharpener which I think is very good value for money. The cutting edges seem even sharper than when new. We have already sharpened enough bits for this sharpener to have paid for itself.

This rocks and saves my shop lots in cash

Very effective. Quiet, simple to use. Nothing really to dislike about it. I bought one for my home workshop a few months back, and now I've bought a second one for use at work.

So I bought this because my sad looking pile of blunted drill bits has been getting ever bigger.My old drill sharpener from twenty years ago will sharpen them, but can't do the split-point grind that you really need with modern drills, particularly on the larger sizes. This new one can.Out of the box, the adjustment for the collect rest for the split-point grind wasn't exactly right, and given that you can adjust three separate things for the split-point part of the grinding process, it took me a little while to work out what needed doing. Once I'd figured out which adjustment it was it took ten seconds to set the machine up perfectly (lateral position of the drill compared to the grinding wheel).Thereafter, between twenty and thirty seconds per drill bit to get them super sharp with little effort or skill required.I've done all the drills I had at work, and any others that my colleagues had lying around. 100% success rate, minimal noise and fuss.Now the machine's set up properly, I really can't find anything to dislike about it. The manual's a bit lacking, but there are a number of Youtube clips showing correct usage so that's not really a problem.Build quality is good, with a proper ball-bearing setup for the collet holder and also for the main grinding 'port'. There's little discernable play or slop in anything. It's surprisingly heavy (not that this is a bad thing) which I think speaks to the rigidity of the guides around the grinding wheel.It came with two wheels - a diamond one for carbide drills, and a CBN (cubic boron nitride) wheel factory installed for HSS bits.I bought this one for home, and now I'm seriously considering buying a second one to have at work.
