It took me a week or so to sit down and try to figure out how to setup and use the drill sharpener. The instructions are terrible. I ended up watching YouTube videos and was able figure things out. The hardest part is setting up what's called "Web Thickness" I believe. Once I got that straightened out the sharpener did an outstanding job on my drill bits. As of right now I'm extremely happy with my purchase!

I cannot believe how good this machine is. It works so well it’s like magic. My only regret is that I didn’t opt for the larger one. All my friends are envious except that they use it as much as I do.

It is the best sharpener I've ever had, never mind jigs, doctors ect. When sharpening I am trying to imitate factory shapes. As I understand the machine they use at factory is about $7000 or more so $250 MR-13B does the job for its price. Yes instructions are not brilliant and I would like to read some directions how to adjust the depth of split point. I do not like the angle it splits the web point and the blur it leaves on cutting edge, the grinding wheel could be bigger and finer, but hey as is it works great!

Works great on sharpening my split point cobalt drills.

Really good unit. Puts a really good edge on drills and repairs broken bits with ease. I wish it would do up to 1" bits.

After a short learning curve on my part, I am very pleased with this machine. The included instructions are not the best but just add in a little common sense, practice and perhaps the right YouTube video, you'll get great results. The trick is correctly setting the drill/chuck alignment in the left hand port. The first few time you do this, it is easy to misalign the drill while tightening the chuck. Always confirm visually that the flutes of your drill are parallel with the flats on the chuck. The little machine is heavy and well built. It uses ER-32 style collets. Typically you find these on precision machine tools, CNC machines and higher end wood routers. That is a good sign of quality. They work very well but require that you understand how to use them. They "snap" in to the chuck cap and are held firmly. To remove from the cap, you tilt the collet to the side and it pops out. Both of these actions require that the collet be empty. At least two YouTube reviewers that I watched did not use the collets properly. Several Reddit posts thought the ER cap was machined incorrectly. It wasn't. Choose wisely. The drill size limitation 2mm (~5/64") to 13mm (~33/64") is not a big deal. Drills less than 5/64" are usually never sharpened, just replaced anyway. Larger would be nice, but it's not too hard to manually sharpen drills over 1/2" diameter. Admittedly all my twist drills are ground at the same 118 degrees and I only bother to split the points of drills 3/16" and larger. I have not tried other settings. This machine works very well for me and is miles ahead of my previous "well known" drill sharpener.

Very practical. Easy to use and works perfect. Very fast to get sharp drill, when you need.

A came across the product through a friend’s recommendation and I was not disappointed. It’s a great product with high quality and a reasonable price. It does what it says and seems to have high quality parts (like the grinding wheel etc).
