Busch® Bur Set - Cleancut Cup 411CCC

$29.95
Total ---

The Busch® 411CCC Cleancut cup burs have a cup head with multiple cutting teeth, precision machined and uniformly spaced, on the inside of the concave shell. These burs are also called concave cutters. As well as the cutting teeth, this bur has a cross-recessed head with four slits which allows metal shavings to fall out. Perfect for rounding off, smoothing and shortening (if necessary) the prong tip in one step. Also used to smooth ear posts and wire ends. Made of tungsten vanadium steel for strength and durability. Use with a lubricant such as Gesswein Lube-Stik (see related products) to facilitate cutting and prolong tool life.

The 3/32" shanks measure approximately 1.75" long. Maximum operating speed varies with bur size. Please consult with ANSI (American National Standards Institute) for speed recommendations.

See the charts below to see the individual burs that are available in the set. Made in Germany.
