Maximum safe speed varies with bur size and is indicated on the box. Use a good lubricant, such as Gesswein Lube-Stik, to facilitate cutting and prolong tool life. Burs measure approximately 1-3/4" long with 3/32" shank. Made in Germany.
Busch Cup Burs are available in three diameters 7.00, 8 .00, and 10.00mm and sold individually. Smaller sizes available and are available in packs of 6,
