CNC Carving tools


Granite router bits and Marble router bits

In this section, you find CNC Diamond carving bits for marble working (widia and electroplated tools) and granite working  (polycrystalline and sintered tools). Stone router bits for both the roughing and the finishing in stone with a CNC stone router.
They are also called CNC milling bits.


How to use CNC Carving bits?
Within each product description, you find also the working parameters. You find standard parameters related to the use of both granite router bits and marble router bits.
Parameters can be changed by following this rule: “less is the cutting depth and higher is the cutting speed of the tool “.
Example:

  • with a cutting depth of 4 – 5 mm the cutting speed is 100 mm / min
  • with a cutting depth of 1 mm, the cutting speed is 500 mm / min

please note that if you increase the cutting speed you must also increase the bit rotation speed.

About the down feeding speed into the material we recommend a speed not exceeding 100 – 120mm / min with a ramp entry that has an angle of 10 – 20 ° with respect to the surface of the material.
It is recommended to always use plenty of water for the tip cooling.
Almost all our router bits are also available in the holed model for internal water passage so as to permit an even more effective cooling.
