$9.99
Overview
SpeTool's 1/4-inch ball nose is ideal for roughing passes in 3D carving and for medium-resolution relief work. The larger diameter removes material faster than 1/8-inch ball nose bits, making it perfect for the roughing toolpath before switching to a smaller bit for finishing. Solid carbide handles hardwoods without issue.
Best for
3D roughing passes and medium-detail relief carving in wood.
