Good bits. Used them quite a bit and have been good on holding up. I bought another set.

Can't beat them for the price

Good selection of burrs. Worked well - no nicks nor chipped teeth after the equivalent of a couple hours of use in mild steel.

I purchased this item for cleaning up steel items shaped either by grinder or plasma cutter. They work as expected saving loads of time that would have been required using files.

For the money you can't go wrong... I've used them for trimming both wood and metal and in smoothing welds... no problems.

Very good quality for the price. Have used these with my portable and air drills to grind both plastic and metal on my auto projects.

I'm using these with cheap HF die grinders, and they still chew through metal like nothing. They are very hard as well and I haven't noticed any wear on them yet. I'd highly recommend.

This is a great industrial set for working in the fab shop. You won't be disappointed...

These dig into carbon steel like butter. So far I like the cone bit best but you can easily find a use for all of them. I've put a decent beating on them and they hold up just fine but they can hop around on thinner material and chip a tiny bit.

These are great carbide cutters. I've purchased lots of cheap cutters in the past, and they get dull and grind down faster than the work piece. These cut clean, fast, and smooth and stay sharp! I'd buy them again in a minute - but I don't need too because they last!
