Christopher G. ★★★★★

Took this ball burr to some stainless steel and it chewed through without loading up. The 3/8" diameter is perfect for deburring those tight inside corners.

Hazel Q. ★★★★★

I’ve been using this burr on a hardened tool steel jig, and it cuts cleanly without much chatter. The 3/8" ball end lets me get into tight radius corners I couldn’t reach before. Definitely holding up better than the HSS bits I was burning through.

Samuel R. ★★★★★

Using this on some stainless steel and it cuts through surprisingly clean without loading up. The 3/8" diameter is a nice middle ground for detail work without being too delicate.
