The STEPCRAFT HF Spindle is a technical product with high precision, stability and quiet running. The HF 500 are cylindrical spindles with a compact design and equipped with an asynchronous motor to provide high torque levels. High capacity ball-bearings (3x) bring the concentricity accuracy and a long tool life. Additional advantages are high stiffness, low-vibration running and long-life grease lubrication.

For the application of the tool with a STEPCRAFT or a third-party router additional ER-collets are necessary. The ER collets are not included in the scope of delivery.

When using the HF Spindle together with the Enclosure the Extension Cord for the HF Spindle is required in the respective length: 

• Enclosure for STEPCRAFT D.300: no extension cord necessary 
• Enclosure for STEPCRAFT D.420: 1 m extension cord necessary 
• Enclosure for STEPCRAFT D.600: 2 m extension cord necessary
• Enclosure for STEPCRAFT D.840: 3 m extension cord necessary
