Aircat Pneumatic Tools 6255 Composite Angle Die Grinder | 0.4 HP | 20000 RPM | 1/4" Collet Size | Rear Exhaust

When tight-access finishing work requires more speed and motor output than a compact mini angle grinder, the AIRCAT 6255 1/4" Composite Angle Die Grinder gives technicians a right-angle pneumatic tool for controlled blending, smoothing, porting, deburring, and edge cleanup. Its 0.4 HP motor and 20,000 RPM free speed support work with compatible mounted stones, carbide burrs, sanding accessories, and other properly rated rotary accessories. The 1/4" collet size accepts matching 1/4" shank accessories for confined-area repair, fabrication, manufacturing, commercial, and maintenance tasks.

At 1.10 lbs. and 7.00" long, the 6255 provides an angled-head layout that helps position the accessory around brackets, housings, panels, service cavities, castings, and close-clearance repair areas. The spiral bevel gear set transfers power through the right-angle head, while the rear exhaust directs air away from the front of the tool and work surface. AIRCAT lists this model with patented quiet technology at 82 dBA, superior steel-grade internal bevel gears for longer life, and a feather trigger for improved speed control during detail grinding and finishing work.
