At first glance, you might think a miniature chamfer bit cuts the same edge as a full-size chamfer bit—a 45 degree angle, right? Right. But where these miniature bits excel is in cutting inside corners. Because of the tiny guide bearing, they cut deeper into the corner, and because of the smaller overall diameter, they leave a much tighter arc. If you intend to chisel out the corners, the hand work is sharply reduced, and in many cases, no hand work is necessary. Ideal for smaller scale pieces such as music boxes, jewelry boxes, humidors, and more.
