Eva ★★★★★

I’ve had other bits wander on tricky grain, but this one tracks perfectly thanks to the double bearings. The AstraHP coating seems to reduce friction noticeably, making the cut feel smoother. It’s already saved me from having to redo a few cabinet edges.

Miles H. ★★★★★

Finally, a flush trim bit that stays sharp through multiple plywood edges without any burning. The AstraHP coating really makes a difference in cleanup.

Victoria B. ★★★★★

The double-bearing design really shines on curved edges—no chatter, just a smooth, even cut every pass. The AstraHP coating kept the bit clean even after a long afternoon of trimming oak, and it still feels razor-sharp.
