Chicago Pneumatic 6151950104 Pencil Grinder Kit 7 Cfm

Product Description

The CHICAGO PNEUMATIC 6151950104 is an air-powered pencil grinder kit designed for precision grinding, deburring, porting, and surface finishing work. Running at 60,000 RPM no-load speed and consuming 7 CFM at 90 psi, this tool delivers consistent rotary power through a compact, pencil-style body measuring 5.2 inches in overall length. The kit includes collets for both 1/8 inch and 3mm shanks, along with five carbide burrs and five mounted points, making it ready for immediate use across a variety of material removal tasks. Rear exhaust directs spent air away from the work surface. Rated at 0.05 horsepower, it is suited for light precision work in fabrication, tool-and-die, and maintenance applications.

This pencil grinder kit is intended for use by machinists, maintenance technicians, fabricators, and industrial tradespeople who require a small-diameter rotary tool for tight-access grinding and finishing. The 3mm collet size and included accessory set make it practical for die work, weld cleanup, and port matching. It connects to a standard air line via a 3/8 inch inside-diameter hose. Operating pressure is 90 psi, which falls within the output range of most shop compressors. The CE certification indicates compliance with applicable European safety standards, making this unit suitable for both domestic and international shop environments.
