MRCM Drill Bits Sharpener,3mm -15mm Drill bit Grinding Machine MR-13A, 95° to 135° Point Angle Re-Sharpener, Portable Bits Sharpening Machine with 13 Collets，All-Metal Housing

The instructions are terrible, but thanks to a YouTube video, I was able to figure it out. Sharpens bit in only a few minutes. Setup is quick and easy. Bits are very sharp. Well worth the money. Very good quality.

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.

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.

Pricey but amazing. Large bit sharpen very well. Very easy to use. I did not offer 5 stars as the small collets for drills do not hold the bits firmly.

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.

Absolutely the best drill bit sharpener I've ever used, including by hand. The 13D does everything it's supposed to exceptionally well. The only complaint I can come up with is the depth and orientation fixture requires a little patience to get it to function as intended. I wish there was a way to adjust it but if you are mechanically inclined enough to sharpen your own bits then you should have no problem figuring it out with a little time. I did contact the company and the customer service was exceptional. My only regret is I didn't buy this sooner.

Glad I took a chance on this - I’m happy with how well it works. Sharpened several drill bits after watching some YouTube videos. It was fairly easy to fine tune the split point back angle. Was able to get nice results on both high speed steel and cobalt drills with different angles. Didn’t find any issues sharpening fractional drills with metric collets. It will be nice to always have sharp drills ready when doing projects now.

Purchased many “handy” things in my day. Had the drill doctor, was not impressed. This tool puts a perfect angle and split relief point on almost every single drill bit I own. Nothing worse than loading a bit only to find it dull. Not an issue anymore. I sharpened titanium coated, cobalt and general use bits. Maybe 200 in total in one rainy day. So impressed passed to my friend and he sharpened probably 350 bits in a couple of days (his tool hound brother was visiting) both so impressed I think they both ordered one. We have all bought the combination socket wrench screwdriver cheese grater spark plug tester with the hopes it is a better way to get the job done. This is a great tool.
