Carbide Inside Ring Burs (1/8" shank)

Carbide Inside Ring Burs (1/8" shank)

US made carbide cylinder burs ideal for grinding the insides of ring shanks and other large areas. 1/8" shanks.

The Basics

  • Cylinder Burs can be used like a flat file. They can remove large amounts of material quickly. Large cylinder burs are useful for grinding the insides of ring shanks to increase their size.
  • 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.
