Features and Benefits:10,000 RPM;3/32" Orbit;7.75 x 2.75 Rectangle hook and loop pad;Advanced silencing technology reduces noise level to (80 dBA);Patented doubled sealed, lubrication-free motor prevents dust contamination and eliminates the need to oil the tool;Patented "anti-vibration" motor reduces vibration level to 1.8 m/sec2;The AIRCAT line represents the most significant advances in the performance of pneumatic power tools in nearly 30 years. Founded in 1998, our tool line has a substantially reduced level of noise while retaining more power and torque. AIRCAT also incorporates a patented ergonomically engineered handle design to relieve stress and fatigue on the operator�s hands, wrists and arms. AIRCAT has the patented tuned exhaust muffler technology in most tools, which allows discharged air to pass without developing back pressure, thus retaining more power, while significantly reducing noise.
