Made of tungsten vanadium steel for strength and durability. Teeth are precision machined and uniformly spaced so cutting is accurate and smooth. Available in two diameters: 1.00 and 1.20mm.
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.
