Bits for rough-cutting and finishing bas-reliefs
Carbide, diamond electroplated, rounded, and ball-noded bits for CNC machines to work marble, granite, and ceramic

These tools are designed for bas-relief roughing, material removal, and finishing.

  • Carbide and electroplated bits are used to work marble and limestone;
  • Polycrystalline and sintered tools are recommended for harder materials such as granite, lava stone, and engineered stone

We offer bits having various cutting angles, radii, and, cutting edges up to 120 mm (ball nose – round).
Most of our bits have a 1/2 gas connection, others have a 14-mm cylindrical connection.
We offer bits with cutting angles of 20°. These are very precise bits able to operate in the most hard-to-reach areas of a bas-relief.
Each product page provides the working parameters for granite and marble tools. These are generic parameters referring to the use of a bit on a solidly based machine with insignificant vibration.
Generally speaking, the parameters can be changed in accordance with the following rule: “the shorter the cutting depth per pass, the greater the feed rate at which the bit can work”
For example:

  • with a cutting depth of 4-5 mm per pass, the feed rate is 100 mm/min
  • with a cutting depth of 1 mm per pass, the feed rate is 500 mm/min

Note: if we increase the feed rate, the bit’s speed of rotation must also be increased.
As regards the plunge rate into the material, we recommend a rate no greater than 100–120mm/min with ramp purge motions that do not exceed 10 – 20° with respect to the material surface.
Always use enough water to cool the bit.
Almost all the bits come with a bored through-tool version allowing water to pass through the bit, cooling it more effectively and removing undesired cutting debris.

CNC Stone router bits may be used used for roughing and finishing stone with a CNC stone router.


These bits have diverse names and are also known as CNC milling bits, CNC Stone carving bits, Granite CNC Router Bits, Marble CNC Router Bits, Stone CNC Router Bits, Quartz Router bits.
