Drill Bits Sharpener, 3-20mm Grinding Machine, Lip Relief Angle & 95°-135° Point Angle Adjustable Drill Bit Re-Sharpener, Portable Sharpening Machine with 18 Collets, MR-20G

This sharpener is the best on the market in my opinion. I have sharpened hundreds of drills from 1/8 to 3/4 of an inch on this machine. It's is very simple to use with no complicated settings or adjustments. It just plain works right out of the box. I would highly recommend.

First, like most people have said, the instructions for use are lacking. Other than that, I am extremely pleased with the product. I bought the one that goes up to 3/4 inch bits and it works just fine on the larger bits as well. I’ve probably sharpened about 200 bits so far with no issues whatsoever. I would highly recommend spending the extra money to do the split point. I’m sharpening all my bits now to 135 degrees with a split point. I had a drill doctor before and this works way better. As for the seller, we had some misunderstanding on what was included with the product based on their description, but to their credit, they recognized the discrepancy, corrected the description on the listing, but even better, they honored their mistake and sent me an extra sharpening stone. Good on them! I will add, up to this point, I see no wear on my existing grinder stone and the entire unit seems very solid. If I had any other complaints, it would be that the individual collets are not clearly marked and I think the holes that they are stored in could be better marked. Also, it would be nice if there was a place to store the chucks that hold the collets ( mine has two, since mine goes up to 3/4”) with the machine. Other than that, if you can afford it, it’s a solid product and I am very pleased with it, especially compared to my drill doctor, which I have now parted with. Yes I would recommend.

Excellent machine! It's done a great job for hundreds of drills for me. Today I sharpened 48 drills, from 3/32" to 3/4". I turned to collects around and see I have them all. The machine is very tight tolerance and the collet holders are super rigid when sharpening. Love this machine.

I am very satisfied with my purchase. Instructions are another matter as others have noted. Vevor sells the same thing in a different color it appears, so I looked on you tube for instructions on how to fully use the machine.

Having gotten disgusted with the plastic D Dr sharpener that I had for years (that would no longer hold or sharpen a bit correctly), I decided to take a chance on this machine. Based on YouTube reviews, it was supposed to be pretty good. The You Tubers all said the included instructions sucked, and they weren't exaggerating. I started to give it 4 stars for the sketchy instructions, but the thing works so well I thought that would be a little unfair. It's not a Darex, but it doesn't cost $2500+ either. A little to my surprise, this thing works really well and it is quick (especially compared to plastic Dr)! I have a small machine shop and sharpen more than a few drill bits. This thing gets it done! It's made of metal - no plastic! The collets and holders are good quality and the fixtures are accurate. I recommend this sharpener. Even though the collet and fixture graduations are metric, it works just fine on all standard bits. Just be sure to get your instructions from You Tube.

Does a great job

Fussy to use but worth the effort.

I've ground drill bits in various ways, free hand, jigs, drill doctor. This is a better way to go and set up is quick. The collets spring enough that I can sharpen metric or standard from any number sizes, to letter sizes and fractional. One thing I did was modify an er40 collet chuck to fit this machine and it sharpens up to one inch. I happen to have the collets on hand that fit the larger sizes. It's really nice to drill and sharpen easily between uses. I've sharpened in excess of 50 bits so far.

Cannot use this drill sharpener without additional purchase of step down transformer.
