Customer Reviews for VEVOR MR-20G Drill Bits Sharpener 3-20mm Bits Grinder Sharpener with 18 Collets

The grinder is good. That part is fine. The instructions are a bit lacking. I think the instructions are pretty generic, as there are several variations of this small drill grinder. This particular model, the MR20G has a bunch of adjustments that are not explained in the manual.

Works as promised

This is an amazing tool that's easy to use once you become familiar with it. It leaves you with a professional cut like it's a brand new bit and will save any shop that uses a lot bit a lot of money. I recommend watching one of the how-to video that are out there and learn with a old drill bit, as the instructions aren't great. This is why I gave 4 stars overall. Otherwise I love the tool.

Assez bon produit, manipulation facile

Very nice sharpener and all I need for my uses. Would be nice if it could sharpen to a bit smaller sized bits, but it covers most of what I use. Better instructions are really needed. The grammer is terrible. The worst part is the section describing the placement of the pins for different sized bits in the 2nd step for tip splitting. There should just be a table saying where to set them for different size ranges of bits. Basically, it's just trial and error now. But, sill way better then anything else for twice the price.

This has worked very well for my needs. I struggle with the smaller bits by hand, I lost my sight recently, so this is helping a lot. I did find it finicky at first, the setting dial to set the drill up is not matching the size of the bit. Now I just leave it where it is ... which is halfway, pull the bit out and make sure it's level with the flats on the holder. I also had to adjust the in and out of the thinning / splitting on top. Once I did that, it's been perfect. The instructions are poor, but there are enough videos to get you started. I probably should have bought the larger grinder. I have not used the diamond yet, the CBN is perfect for HSS. None of my carbide drills have been sharpened yet.

Fungerar bra och enkelt att använda.👍

Works great

El afilador de brocas funciona bien aunque los acabados dejan mucho que desear, las instrucciones de afilado son pegatinas, que muchas veces no están bien apegadas y se despegan. también algunas pegatinas de la maquina no están bien en su sitio, apuntan hacia una dirección incorrecta, respecto al útil de afilado. Tendría que estar todo troquelado en el cuerpo de la afiladora, para que no se pueda deteriorar nunca. La calidad del ensamblaje de la maquina, varia de unas maquina a otras, unas vienen mejor ensambladas que otras, por lo que el control de calidad no es muy bueno.
