Set of 9 includes one each of sizes 008-016 Busch® Carbide Pavé Cut burs (447AU) a unique, (patent-pending) combination of a twist drill and a round bur. This game changing bur allows the need for only one tool/bur for pre-drilling, shaping and enlarging! These burs are perfectly shaped to prepare your jewelry for pavé setting. Pavé Cut burs are also available for individual purchase, sold in multiples of 2. Recommended speed is 5,000-10,000rpm. Mounted on 3/32" (2.38mm) shank. All Busch® AU style carbide burs have precision-cut edges, so they cut more aggressively and are longer lasting than standard carbide. Well suited for use on hard metals (such as platinum, white gold, titanium, and steel). Engineered with precision in Germany.
After drilling it is necessary to make a clean cross cut with a Busch® 231F or 231FL Circular Saw. Choose the saw thickness (0.2mm - 0.3mm) to cut the desired notches for the stones. These saws are not included in the set of Pavé Cut burs but are sold separately in multiples of 2.
