What tools can I use with the ER40 collet?

The ER40 collet system is designed for heavy-duty industrial work and can accommodate tool shanks ranging from 3mm up to 30mm, allowing for very large material removal bits.

Why is the 4-pole design important for stone carving?

A 4-pole design provides much higher torque (5.76 N.m) compared to standard 2-pole motors. This ensures the spindle can maintain its RPM while cutting through hard materials like stone and granite without stalling.

What type of VFD is required for this 7.5kW motor?

You will need a high-frequency Variable Frequency Drive (VFD) rated for at least 7.5kW (10HP) that supports an 800 Hz output frequency and 380V 3-phase input.
