Overview
The SpeTool 1-inch surfacing bit is designed specifically for flattening spoilboards and surfacing large areas quickly. The 3-cutting-edge design removes material efficiently while leaving a smooth, flat surface. With a 1/4-inch shank, it fits the collets on most hobby CNC routers, though users should take light passes due to the small shank.
