Kick ass bits work really good

I am a heavy mechanic and use these all the time. They are very sharp and grind and de-burr excellent! Outstanding buy, especially because the tool trucks are 4-5 times the price

Really good bits for the price, been using them for a year and only burned out a couple after heavy duty chewing

Great tools to have in the toolbox. Have used them on many items and yet they remain sharp for smooth cuts. Can’t complain, these are worth their bucks. So far, so good… 👍🏼

I bought these grinding bits to give welds a better finish look. They work very well for grinding down welds. I am sure they will do the same for other metal finish projects.

Very good product

Quality die grinder burrs at a great price.

for an inexpensive set of die grinder bits this works great. I have been impressed with the cutting ability and the fact I have used this a lot and seems to keep its sharpness. The sizes are nice! I would recommend

El producto es excelente, sin embargo me llegó con la cajita quebrada, pero no es culpa de quien lo envía si no de la paquetería al momento de transportarlos sin embargo se tardó bastante la entrega era a domicilio tuve que pasar a ocurre DHL,les dejo una imagen del producto

For that price , that kit of burrs is awesome. I used one on metal and it worked great. I always use a bit of oil when working on metal to make them last.

Los compré para mi esposo. Le gustaron. Son útiles y buena calidad.

Cuts fast, fairly durable and cheap. As long as you don't let them grab/skip/jump they cut steel nicely without wearing. update 8 June 2026: Still in good condition and quite handy. I bought them at 40$, lowest price they have been is 30$

They work, we will see how long they stay sharp
