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.
