Category: Classical Round Bottom

The Classical Round Bottom router bits are used for decorative designs in cabinet doors or for detail veining in furniture. Round Nose Bits and V-Groove Bits are often used in the same manner. The larger Grooving Bits are great for a raised panel effect in doors and for adding a bold accent to furniture or large work pieces. These bits also make nice edge profiles with the aid of a router table and fence. Can be used in CNC, router and router table applications.

Abigail ★★★★★

Installed this bit to add decorative veining to some oak cabinet doors and the AstraHP coating kept it running cool through the whole set. The round bottom cut a clean, smooth channel without any burning.

Ellie ★★★★★

Bought this for veining detail on a walnut buffet and the cut came out glassy smooth, no tearout at all. The AstraHP coating seems to help it stay sharp longer than my old bit did. The 1/4 inch shank seated solid in the collet with zero wobble.

Emma ★★★★★

Cut clean profile lines in maple cabinet doors with zero tear-out, which surprised me for a 1/4" shank bit. The 1/8" round bottom leaves a nice subtle veining detail that sanding doesn't wash out. Ran it through about 60 linear feet and the edge is still sharp.
