Miles G. ★★★★★

Bought this to engrave fine lettering into stainless steel and the 4 flutes leave a noticeably cleaner finish than the 2 flute I was using. The .050 ball tip handles tight curves without chattering, though you do have to keep the feed slow.

Timothy F. ★★★★★

The 1/8" shank dropped straight into my router collet, no adapter needed. Cut a batch of cherry inlays with the .050 ball tip and the curves came out glass smooth. Four flutes keep the chip load light, so even at a slow feed it never grabbed.

Owen B. ★★★★★

Bought this to cut small fillets in 304 stainless and it's held up way better than the cheaper 2-flute bits I used to burn through. The 1/8 shank fits my trim router collet perfectly, and the 4 flutes leave a surprisingly clean floor finish.
