- Spindle opening: 6 to 7 mm. This range provides compatibility with parts and tooling that fit a 6-7 mm bore, delivering a secure grip and reliable operation. - Speed adjustment knob: adjustable spindle speed with clockwise for fast rotation and counterclockwise for slow rotation. This allows you to tailor performance to material and task for better control and finish. - Replacement spindle holder: includes a spare spindle holder for quick maintenance and reduced downtime, helping you keep projects moving. - Infrared induction: infrared induction feature built into the unit for responsive operation and convenient control. Typical applications and use scenarios - Precision detail work on small components such as electronics enclosures, hobby parts, or model components, where a secure spindle grip and adjustable speed improve accuracy and finish. - Finishing tasks including deburring, polishing, or engraving on plastics, wood, or light metals, where the 6-7 mm spindle opening and variable speed provide versatility and control. - Maintenance or repair workflows where quick replacement of the spindle holder minimizes downtime and keeps work progressing smoothly.
