When high-speed grinding, deburring, and finishing work requires more motor output than compact mini die grinders provide, the AIRCAT 6285 1/4" Straight Die Grinder with Spindle Lock gives technicians a powerful pneumatic tool for controlled material removal. Its 0.75 HP motor and 23,000 RPM free speed support work with compatible mounted stones, carbide burrs, and properly rated rotary accessories. The 1/4" collet size accepts matching 1/4" shank accessories for edge cleanup, burr removal, gasket-surface preparation, casting cleanup, weld-detail blending, and general shop finishing.
The 6285 is built with a spindle lock feature to make accessory changes easier, helping reduce the extra steps often required when changing burrs or mounted points. At 1.40 lbs. and 7.00" long, this straight die grinder provides a manageable body size for repeated grinding and finishing work. AIRCAT lists this model with a 79 dBA low-noise rating and 2.5 m/sec² vibration level, while the speed control switch on top of the grip gives the operator added control during surface blending, deburring, and cleanup tasks.
