• BALANCED ROTOR DESIGN: The variable speed polishing machine uses a balanced rotor to minimize vibration, delivering smoother operation, lower noise, and more precise finishes. Reduced oscillation also lessens bearing load, supporting longer service life and more consistent results over time
• Extended Polishing Shaft & Coarse/Fine Wheels: 8-inch variable speed bench polisher buffer features a longer, reinforced polishing shaft and a high-precision powder-metallurgy chuck, allowing for stable, accurate polishing of larger workpieces. The dual polishing wheel design efficiently removes material from rough surfaces while achieving a high-gloss polish on fine surfaces
• STABLE CAST IRON BASE: The solid cast-iron base of this variable speed buffer polisher provides maximum stability and reduces vibration during intensive polishing. Benchtop polisher heavy-duty construction enhances precision, ensures smooth rotation of the polishing wheels, professional-grade performance for continuous use. The VFD motor may cause a GFCI outlet to trip. Do not use power outlets with GFCI function. It is recommended to use an HACR circuit breaker
