Finger Bits

Finger Bits

Wide range of Diamond CNC Finger Bits for CNC machines, working centers and radial arm machines.
When working the stone with a CNC machine the finger bit is one of the most common tools because it’s used for milling away material and cutting any arc in stone.
We offer different types of finger bits to provide a fast and precise cutting with a long lasting lifespan in any material:

  • Electroplated: marble
  • Sintered: with hard bond for soft stone 
  • Sintered: with soft bond for hard granites to engineered stone
  • Sintered: with very soft bond designed for the hardest stones like quartzite

A soft material must be cut with a hard binder finger bit; a hard material requires a soft binder bit.
The standard thread size for finger bits is 1/2” gas but you find also bits with cylindrical shank or flange connection.

For further information and service don’t hesitate to contact us: info@amastone.
