Very Durable!
I got this bit to do some porting on some aluminum auto partsI'm using it with a cheap harbor freight electric die grinder, and this thing works AWESOME!Not only does it cut like a hot knife through butter, but after doing a Supercharger Plenum and the Supercharger case itself, the coating still looks new! No visible wear, and still feels sharp!This thing is going to get a lot of work in the next month or 2... I don't see it ever wearing down!!

Superbly made, great product
These things are rather useful and indispensable when you have a lot to deburr or can't get a hand file in where you need it. The carbide seems to have been polished smooth - the quality is that good. The TiN coating will certainly help retain the edge at least twice as long and aid in better finishes. All around a tiny but great tool. Made in USA.

Good bur; not carbide
I purchased this bur to use for woodwork (hollowing operations) using an electric die grinder. It runs and cuts well, but it is made of steel ... presumably HSS. On the one hand, I wanted carbide (especyally for $30+) and am somewhat disappointed. On the other hand I subject it to lightish duty and can get by with HSS. But how soon will the lifetime difference rear its head? Carbide is more durable, even in wood.
