Inverted Cone Carbide Burs (1/8″ shank)

Inverted Cone Burs are shaped like an upside-down cone and are well-suited for making undercuts for stone setting and remove excess solder from tight spaces.

Carbide Steel burs maintain their sharpness longer than any other steel. They are more brittle than carbon steel and hss and are more likely to break or chip if mishandled.

1/8″ dia. shanks are larger than the standard 3/32″ tools most used by jewelers. These larger tools fit most adjustable chucks but will not fit most quick-change handpieces.
