When grinding, deburring, and finishing work calls for a compact straight die grinder with a higher operating speed than 20,000 RPM models, the AIRCAT 6225 1/4" Straight Die Grinder gives technicians a lightweight pneumatic tool for controlled material removal. Its 0.5 HP motor and 22,000 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.
At 1.30 lbs. and 7.00" long, the 6225 provides a compact straight-body layout for detailed grinding while maintaining enough reach for common repair and fabrication tasks. The low weight composite housing helps keep the tool manageable during repeated finishing work, while the high quality 3-piece precision collet supports secure accessory holding. AIRCAT lists this model with a safety lock-off trigger for added safety, precision bearing construction to reduce vibration and spindle run out, and built-in silencing to reduce noise levels.
