## Description

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 - desertcart.com

Review: Professional results that anyone can achieve - 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.
Review: Works well, seems like a solid machine that is built to last - 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.

*by B***. on April 20, 2025*

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.
