Chicago Pneumatic 8941074050 Air Die Grinder 0.34 Hp

Product Description

The CHICAGO PNEUMATIC 8941074050 is a straight-body pneumatic die grinder built for grinding, deburring, porting, and surface prep work in fabrication, automotive, and industrial maintenance settings. It runs at 28000 RPM and draws 2.7 CFM at 90 psi operating pressure, delivering 0.34 HP from a composite housing that keeps weight down to 1.6 pounds. The comfort grip handle reduces fatigue during extended use. Rear exhaust directs air away from the work surface, keeping the cut area clear. Licensed HVAC technicians, machinists, auto body technicians, and general maintenance professionals are the primary installers and users of this tool.

This die grinder suits light to medium grinding and finishing tasks across residential, commercial, and industrial environments. The straight-style body fits into tight spaces where angle grinders cannot reach. It accepts both 1/4 inch and 6mm collets, giving it compatibility with a wide range of mounted points, carbide burrs, and grinding stones. The 1/4 inch NPT air inlet connects to standard shop air supply lines. At 6.9 inches in overall length, it stays maneuverable in confined work areas.
