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 Stone Setting Burs are available in diameters 1.00 to 8.00mm.  Sizes 1.00 – 2.75 are a six-piece minimum order. Sizes 3.00 – 8.00 are sold individually. Also sold in a 16-Piece Set (1 each of all sizes).
