$10.99

Overview

The tapered ball nose combines the fine detail of a 1/8-inch tip with the strength of a 1/4-inch shank through a gradual taper. This design is significantly stronger than a straight 1/8-inch bit while still providing fine detail in 3D carving. Ideal for deep relief carvings where a straight 1/8-inch bit would be too fragile.

Best for

3D carving with extra strength from the tapered profile.
