Used for edging and grooving wood, Dremel router bits are ideal for routing, inlaying and mortising in wood and other soft materials. The Piloted Beading Router bit is designed to guide the accessory along the edge of the material to add a decorative cut. The 612 Piloted Beading bit features a 3/32 In. (2.4 mm) cutting diameter that can be used to round the top edge of a work piece. Can be paired with the Dremel 231 Shaper Router Table or the Dremel 335 Plunge Router attachments.
