Altough these Carbide are ok Do not push much pressure on it it Will bend, it's not that bad just do not push to much, these Carbide They do work quite good, lately did not use it as I have Blue Carbide for dremel Tool, I did not receive exacly Like in the Picture, this was did buy on Snap Up on Bangood, A little cheaper, I do not have this jellow on Carbide, there is one Tool Like dremel but much bigger 6mm not for dremel Tool but I did have adapter 6mm to 3.175 that Works in that way Like dremel but at that point it become a bit dangerous because of 400w and real(probbably) 28000 revolutions per minute, does not have potentiometer, it is Industrial quality, On one machine on woodworking to grind where one big Tool with blade goes into, I do have same pro Carbide from England and these Will not bend easy I mean 6mm one, not cheap, These small one is for hobbies, as same did gift it because I already have one set, Thanks
