Description
Product Description of Dynabrade 56873 3-1/2" (89mm) Dia. Dynorbital Supreme Random Orbital Sander, Self-Generated Vacuum
• Self-Generated Vacuum Dynorbital Supreme includes low profile, premium urethane weight-mated sanding pad. Ready for connection to optional portable self-contained dust collection system. 3/8" (10 mm) diameter orbit.
• Dynorbital Supreme models run at 12,000 RPM. Rotor utilizes five blades and produces more useable power. Composite rotor is stronger and has better lubricating qualities, enabling blades to last longer.
• Composite base has integrated rubber over-mold creating a non-slip feel, as well as insulating from cold. The air motor is suspended by vibration-absorbing rubber rings (Patent No. 5,319,888) to minimize vibration.
• Triple-sealed front double row balancer bearing (Patent No. 4,854,085) is guarded from sanding residue for long life and lower maintenance; easy replacement using 57098 Repair Kit.
• Anti-clog design (Patent No. 5,319,888) enhances the vacuum pick-up on self-generated models. Dust particles are directed away from the air motor (reducing contamination) following a smoother, easier path of extraction. Comfort Platform provides additional hand and wrist support, further enhancing operator comfort. Also offers increased protection against cold air exhaust. (NOTE: Comfort Platform is removable.) Order 59330 Comfort Platform (U.S. Patent No. D610,428) separately, to install on existing tools!
