Eva ★★★★★ Oct 22, 2026

The bearing rides smooth and true, and that 1/2" shank gives me zero chatter even on long oak sill runs. I've already used it for finger pulls on cabinet doors too, and the profile came out crisp with no tear-out.

Scarlett K. ★★★★★ Oct 21, 2026

I was a little nervous about trying a window sill bit on cabinet doors, but the bearing guide keeps everything perfectly aligned. The carbide edge is still razor-sharp after a dozen passes through dense maple.

Ava I. ★★★★★ Oct 20, 2026

Cut these down on a test piece of oak first and the bearing ran smooth with zero burning. The finger pull profile is exactly what I needed for my bathroom vanity doors.
