Is this spindle suitable for granite and marble carving?

Yes, the 7.5 kW power rating and 3.18 Nm torque provide the cutting force necessary for dense materials like marble and granite, while the water-cooling ensures the motor doesn't overheat during long carving cycles.

What tools are compatible with the ER32 nose?

The ER32 system is highly versatile, supporting tool shanks from 2mm up to 20mm. This is ideal for using everything from fine engraving bits to large material removal cutters.

Why is the 4-bearing P4 configuration important?

The P4 precision class ensures minimal runout, while the 4-bearing layout (7008 and 7005 combination) provides the axial and radial rigidity needed to handle the significant pressure of metal and stone machining.
