After re-sharpening a couple of dozen 118- and 135-degree drill bits, I'm generally impressed with the results. Grinds are symetrical, bits cut evenly on both faces, holes have minimal "wobble". The included instructions are pretty useless -- you'll need watch a YT video to get up to speed. The collet collection covers 1/8 - 1/2" bits. Collets are ER-20 and ER-25 style. Dialing-in the bit-diameter (web-diameter) is pretty low-precision -- the alignment arrow is an inch away from the dial. My biggest complaint is safety-related: while grinding the point angle on the side port, the abrasive wheel is visible in the top port and it's pretty hard to find a position that's out of the "line-of-fire". Eye/face protection is a must, and the same goes for respirator masks. The collet storage is okay (unless you transport the sharpener 'cuz all the collets will fall out of their retainer holes) but there's no place to put the workholder, kind of a big oversight IMO. All that aside, the unit consistently delivers sharp, well-formed drill bits, which, if you'll excuse the pun, is the whole point.

If you are considering this, I would suggest reading the review, and then just buy it. It is a great machine, and very easy to use once you get some experience with it. This Vevor Drill Sharpener, made by MRCM, compares very favorably with machines costing ten and 20 times the price. I paid full price for the sharpener.Pros: It is very precise and accurate, and able to grind many different points on bits, including accurate split points (aka crankshaft grind) The components are all well machined and heavy duty. It is solidly built. (Which enables accurate and precise grinding) The standard grinding wheel is cubic boron nitride, CBN, which is an extremely hard abrasive, and, if you take your time, it is easy to get a surface finish that rivals new bits. MRCM makes a broad range of professional sharpening tools, and I think that the quality of the engineering in this drill sharpener shows, and makes it easy to use.Cons: The manual is limited. (E.g. the knob to adjust the split point center, and the Allen set screw to hold it were not documented in the manual that I have, but they do work, and enable you to adjust the grind axis to have precisely ground split points bits.)I recommend watching a video or two on YouTube (hint: look for videos of MRCM drill sharpeners). If you are new to drill sharpening, I also recommend any of the Cleveland Twist Drill pamphlets available various places, or the book that the pamphlets came from. I think that drill sharpening is not perhaps rocket science, but like any tool sharpening, does require attention to detail by the user.The holders for the bits are industry standard ER20 collets. You can also buy ER20 collets in SAE/Imperial sizes. It doesn't matter much for larger bits, but may be helpful for smaller bits.Replacement grinding wheels both CBN and diamond are available if you look for them, as are replacement chucks.MRCM is also known as Zhejiang Meiri Intelligent Machinery Company.

Worked perfectly out of the box and immediately saved bits previously sharpened on a competitors machine. Any craftsman knows that drillbits have critical geometry that must be maintained otherwise the drillbit simply will not cut. This machine is extremely precise and has some very fine adjustments that you won’t find on other machines. well worth the money.

The Vevor 13B is one of those rare off-shore products that really works, and works well. Right out of the box I was able to take a cheap drill bit I had on hand, sharpen it and put on a split point (technically thinned the webbing). The sharpened bit easily drilled through some 3/16†plate steel with little effort.The Vevor is sturdy and well made, and the collet has close tolerances so it fits snugly in the sizing and grinding openings. I took off a star for the almost complete lack of included instructions and the horrible (nonexistent) support on the Vevor website. I asked a fairly simple question, and after 4 days of AI-generated blather I turned to Youtube where I found several excellent videos describing the differences between the 13A and 13B, as well as tutorials on how to use the machine. The Vevor works so well that it actually takes longer to watch the videos than to sharpen the bits yourself. But watch the videos, they make using the Vevor a snap.Overall the Vevor 13B is excellent addition to my shop. I hate dulling a bit on a weekend night and having to spend 30’ driving to buy a new bit, or waiting until the next day if the stores are closed. This takes 2’ and I’ve got a new bit ready to go.The obvious comparison is the Drill Doctor. I have a Drill Doctor, but it is a toy compared to the 13B, and costs almost as much. No comparison, the Vevor consistently produces an excellent finish and a fast cutting bit. The Drill Doctor takes longer and is not as reliable; in my hands about half the time I have to take a 3rd or 4th pass with the DR, and sometimes even that does not make a useful bit. With the reliabilty of the 13B bit, the DR will go on marketplace or the scrap heap.

I highly recommend the Vevor drill bit sharpener! It's easy to use and puts a professional sharpen on your drill bits up to size 13mm (approximately 1/2 inch). I have used it to sharpen my bits from 1/8 inch up to 1/2 inch. I have the Drill Doctor 750X and have never been that happy with it. I do not see why the DD 750x gets so good of reviews. I find that it in consistent at best and is cheap plastic. The Vevor is made out of metal and is of excellent quality. I have a degree in Metals Technology and have worked many years being a machinist, although that was many years ago. I still work with all types of metal and do some woodworking. The Vevor will be an excellent addition to your workshop and is well worth the money. I wish I would have found it a long time ago. My only regret with the Vevor is that it doesn't sharpen larger than 1/2-inch bit. Buy it, you won't regret it!

E una macchina Spettacolare!Avevo visto le mille recensioni online della macchina e le mie aspettative erano alte, e devo dire che cio nonostante sono rimasto stupito di come affila le punte!!Una punta nuova non taglia bene come dopo essere stata affilata con questa affilatrice.La nuova versione arancione e a mio avviso molto piu bella della versione gialla che si vede in tutti i video di youtube.Direi che sono entusiasta di questa macchina e non posso che consigliarla.

I own a D.Dr 350X and a 750X. This Vevor MR-13A blows the other two sharpeners out of the water. There are lots of YouTube videos on how to use this sharpener. You will have precision results on the first bit you sharpen. The MR-13A does a superb job of grinding split points if you like to use 135 degree grinds for stainless steel and hardened steel. You can adjust the grind angle from 90 to 140 degrees. I use a 118 degree grind for most of my drilling needs. Although the collets are sized in metric units, they work perfectly on Imperial sized drill bits. I have sharpened over 400 drill bits since I purchased this unit. There is no wear on the CBN grinding wheel at all. I wish I would have known about this sharpener before I spent money on the other machines I had bought. I am totally impressed with this unit. BRD Feb 2025 Update - the sharpener continues to run and operate smoothly. I have sharpened many hundreds of additional drill bits for family, friends, neighbors. Everyone is impressed with the quality of the sharpened bits. This machine has been one of the better purchases for my shop.

Sehr tolles Gerät. Gut verarbeitet und es macht was es soll ohne Probleme und es ist überhaupt nicht umständlich zu bedienen. Die Bohrer sind nach dem schliff wieder super scharf, habe das Bohreranschleifen auch in der Ausbildung gelernt aber bei zwischengrößen wie für Innengewinde ist es schwierig alles exakt hinzukriegen. Auf jeden Fall eine kaufempfehlung wenn man nachhaltig von seinen Bohrern was haben möchte.
