Busch 414 - Bearing Cutter Bur Set

The Busch Bearing Cutter Bur Set includes a selection of precision 90° bearing cutter burs, ideal for creating accurate seats in prongs, channels, and flush settings. Each bur features a conical cutting tip with a flat bearing at the end, producing perfectly squared edges for stones. The cutting flutes extend slightly down the sides of the cone, allowing controlled material removal while maintaining consistent depth and alignment. The bearing tip acts as a guide, preventing overcutting and ensuring uniform results across multiple settings.
