1-1/4インチ ボウル＆トレイビット ベアリング付き x 1/4インチ コーナー半径 x 1/2インチ シャンク – Whiteside 1376B

Hogged out a walnut serving tray and this bit never once chattered, even at the depth passes I was nervous about. The 1/4 inch corner radius leaves that soft inside curve that's a pain to sand by hand, so it saved me a ton of cleanup. The 1/2 inch shank felt solid in the collet too.

The bearing makes routing juice grooves on cutting boards almost foolproof, and I love that I can pop it off to cut clean bowl edges without swapping bits. The 1/4" corner radius leaves a nicely rounded lip that feels good in the hand. Cut through hard maple and walnut without any burning.

Bought this mainly for juice grooves on a few maple cutting boards and the included bearing makes the depth super consistent along the whole edge. It cut through hard maple without any burning, and the 1/2" shank felt rock solid in my router. Finish needed barely any sanding.
