Made of tungsten vanadium steel for strength and durability. Teeth are precision machined and uniformly spaced so cutting is accurate and smooth. 

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 Cylinder Square Burs are available in diameters 0.70 to 3.10mm.

Six-piece minimum order unless otherwise indicated – please order in multiples of 6. Quantity discount on orders of one item number only, not assorted.
