Product Description

The STEPCRAFT spindle is a technical product with high precision, stability and quiet running. The HF-500 is a cylindrical spindle 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. A sealing air system prevents the penetration of dust, chips or liquid to the ball-bearings. The service life will be extended clearly. 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 technical drawing provides the important dimensions.
