Chicago Pneumatic 99V60P109 Pneumatic Grinder

Chicago Pneumatic’s 99V60P109 vertical pneumatic grinder is a 3-HP, 6,000 RPM tool designed for heavy stock removal on a 9-inch wheel. It operates at 90 psi air pressure and delivers a free speed of 6,000 rpm with a 5/8 in.-11 threaded spindle and a Type 27/28 wheel interface, and it uses a side-exhaust arrangement to direct debris away from the operator. The grinder weighs about 11.3 lb, providing a solid power-to-weight ratio for extended use in demanding settings. A 1/2 in. NPT air inlet and a minimum recommended hose size of 3/4 in. define the setup requirements to achieve optimal performance. This model is well suited to heavy stock removal and surface preparation tasks on metal surfaces, offering broad material removal coverage with its sizable 9-inch wheel in applications found in fabrication shops and maintenance environments. Built for durability in industrial conditions, the 99V60P109 is a go-to choice when fast, aggressive grinding on larger wheels is needed to prepare welds, remove rust and scale, or finish large flat surfaces efficiently.
