The 3/16" Orbital Palm Sander, No. SXSN6P01, from SUNEX Tools features Kevlar-impregnated rotor blades that the company says increase the tool's lifespan by 50%. It operates at 11,000 rpm and uses a comfortable rubber over-mold and precision-balanced pad to increase grip and reduce vibrations. It also has a lightweight design, weighing only 2.78 lbs., and has integrated wrist support that both reduces user fatigue and directs exhaust air away from the sander. The sander also uses a low-noise muffler design for quiet operation at 81.2 dB.
