VEVOR Drill Bits Sharpener MR-13B, 3-15mm Drill Bit Grinder Sharpener with Adjustable Lip Relief Angle & 95°-135° Point Angle, 4600RPM High Speed Re-Sharpener with 13 Collets, CBN & SDC Wheels

Alles Top, Top Preis

FINALLY, a drill sharpener that does acceptable split points without costing $3K. I hope you realize how revolutionary this is. I bought a drill doctor back in the 1990s, used it a couple times then put it aside in disgust. Cheap plasticky junk. Everything about this is what I wanted in that product. You can't achieve a true factory split point, but what you can get performs nearly as well. Considering what cobalt bits cost, this little gem pays for itself quick. On a less glowing note, I bought this model, MR-13D, because it does both point splitting and web thinning. Unfortunately these functions can't be micro-adjusted like on the models dedicated for one or the other, nor can they be adjusted independently. I should have gone with one of those dedicated models.

The cat's meow for drill bit sharpening. Drill Doctor doesn't come close comparatively. It went to the Goodwill. For aligning tiny bits, readers and a bright light is a must. Good deal.
