Work great... very well made and are very sharp.

Wow, these abrasion bits really do the job very well. They work very well for grinding metal burr off edges, for shimming off wood...etc. They are tough and after grinding some steel for awhile, they still look new!

Quedaron perfecto en mi dremel y en otra herramienta generica sin ningun problema

Some studs broke in my trucks exhaust manifold and I had a lot of trouble drilling them out. ( I found out later to NEVER use motor oil as a lubricant only cutting fluid.) Anyhow, these bits drilled the bolts very well and are still sharp. I used them in my drill and later at a slow speed in my Dremel tool.

so far I've used three of the different burrs. each one worked great on wood, metal, and fiberglass
