Key Features & Working Principle

• Centrifugal Expansion Action: Centrifugal force automatically expands the precision-slotted rubber drum during rotation, firmly locking the sanding sleeve in place without slipping.
• Fast Sleeve Changeover: When the machine stops, the drum relaxes, allowing instant slip-on and slip-off sleeve replacement without wrenches or tools.
• Smooth Cushioning: Elastic rubber body absorbs vibration, minimizes chatter, and conforms gently to curved and irregular metal or wood profiles.

Available Configurations

• Expander Wheel Drums: Available in M14, M10, and 5/8"-11 thread mounts for international angle grinders.
• Zirconia Alumina (ZA) Sleeves: Coarse grits (P40, P60, P80, P120) designed for high-pressure weld grinding and rapid metal removal.
• Aluminum Oxide (AO) Sleeves: Grits from P60 through P800 for intermediate metal conditioning, rust cleaning, and fine wood contour sanding.
