Widia Engraving Router Bit 20×30 mm for marble
This is a router bit to use with your CNC to make heavy roughing because its tip diameter is 20mm (radius 10mm) and the useful height is 30mm.
This means that marble cnc machinists use it for example when making big reliefs.
The suggested parameters to set in your CNC machine when working with a router bit 20×30 are:
- 2500/3500 rpm, depending on the materials if considered calcareous.
- Feed rate 100/150 mm per minute.
- Maximum depth 30 mm
