BUSCH BURS-HART 70 #446 033(12872)

Hart burs are similar to setting burs except the profiles are angled at 45°, 70° or 90°, angles that make them great for flush setting and cutting seats in prongs; the 45° and the 70° angles are especially great for cutting channels. Hart burs are a little more versatile than the setting burs because the sides can be used like a flywheel to score lines, but they must be handled more delicately than a setting bur.

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, to facilitate cutting and prolong tool life. Burs measure approximately 1-3/4" long with 3/32" shank. Made in Germany.
