1/4インチ コーブ＆ビードルータービット 1/2インチシャンク – Whiteside 3212 (AstraHPコーティング)

The AstraHP coating really does keep the heat down—ran about thirty feet of oak through it and the bit still came out clean, no burn marks on the profile. The 1/2-inch shank grips the collet firmly too, so there’s zero chatter on those long bead cuts. Probably the smoothest cove I’ve gotten from any

I used this bit to run some poplar baseboard trim, and the AstraHP coating really helped the cuts stay clean without any burning. It leaves a smooth finish right out of the router.

The 1/2-inch shank fits my table router perfectly and there's zero wobble at speed. Cut bead profiles in red oak and the edges came out glass smooth with no burn marks. The AstraHP coating really does seem to keep it running cooler than my old bit.
