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

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.

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.

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.

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.

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.

This is a must have drill bit sharpener, I've only had it for about a week now but I have sharpened about 50 bits so far and it leaves a great cut quality and split point on the bits! I would recommend this to anyone it's a great value and saves alot of time sharpening bits! And if you wondering just like I was yes it's basically the same thing as the vevor brand time will tell how long the sharpening stone will last but so far I'm overly impressed!!!!

I have had many drill sharpeners over the years Craftsman, Plasplug, Black&Decker and yesGOD'S gift to dill sharpening a Drill Doctor. I got this this Morning easy to set up and get great results.I read in the reviews that there were no '' detailed instructions'' if you think that put your tools down and step slowly away from the bench! a child could figure this out. I sharpened 50 drill bits with perfect results don't spend more than you have to you won't be sorry .
