Flat-tip carving tool for Marble and Granite – OMGF

CNC Flat-tip carving tool for Marble and Granite

This tool is also called a CNC Flat router bit for marble and granite working. It is ideal for carving kitchen tops and is used to rectify the cuts producing perfect 90° angles, and for rough finishing bas reliefs.
Thanks to its flat-shaped tip, it makes clean cuts on the edges as does not leave any marks typical of electroplated tools.

The version for marble is composed of carbide whereas the version for granite is made of polycrystalline diamond (PCD). The tools are available with and without through-spindle cooling (with a borehole for the passage of water) whereas the polycrystalline diamond version for granite comes only with through-spindle cooling. The shank diameters of all versions are 10 mm.

Operating parameters

Typical parameters to use with your CNC machine when using a flat milling machine like this are:

Marble working (Carbide)

• Spindle speed: 3000-5000 rpm
• Maximum Feed rate: 60 -80 mm per minute.
• Maximum plunge: 2-3 mm per pass
• Ramp plunge moves recommended

Granite working (PCD)

• Spindle speed: 7000 – 8000 rpm
• Feed rate: 200 -250 mm per minute
• Maximum plunge 2 mm
• Ramp plunge moves recommended
• We recommend abundant water with through-spindle cooling
