The solid carbide tip holds up great against hardened steel, cutting cleanly without chipping after several passes. I was pleasantly surprised at how precisely the 3/16" diameter bit fits into tight curves.

Finally got around to using this 3/16" carbide bit for some hardened steel and it cut cleanly without any chipping. The 3/4" length gives just enough reach for small-radius work without flexing.

The 3/16" carbide tip holds its edge way longer than the HSS bits I’ve burned through, and the 3/4" length gives just enough reach for tight radius work. It’s solid, precise, and worth the swap if you’re tired of re-sharpening.
