1/8" Ball Nose Bit — Sculpted Detail Without the Tool Marks

Flat-end bits leave sharp facets on curved surfaces that need hand-sanding to blend. The 1/8" Ball Nose Bit's rounded tip glides through the material, producing smooth, flowing contours right off the machine.

Its small size makes it the right call for fine detail on 3D carving, sign lettering, and any curved profile where a bigger radius would blow past the detail.
