Aircat Pneumatic Tools 6340-A Angle Grinder With Spindle Lock | 1 HP | 11000 RPM | 5/8" - 11 Collet Size | Rear Exhaust

When small-area grinding and surface preparation require a 4-1/2" wheel format with pneumatic power, the AIRCAT 6340-A 4-1/2" Angle Grinder with Spindle Lock gives technicians a compact air grinder for metal cleanup, weld blending, edge work, and repair preparation. Its 1.0 HP motor and 11,000 RPM free speed support use with compatible properly rated Type 27 and Type 28 grinding wheels. The 5/8"-11 spindle / collet size matches common 4-1/2" grinder wheel configurations for automotive, fabrication, equipment service, commercial maintenance, and MRO work.

The 6340-A includes a spindle lock to make wheel changes easier, while the speed control switch located at the top of the grip gives the operator added control during grinding, cleanup, and surface preparation. At 2.25 lbs. and 8.75" long, this angle grinder provides a manageable body size for controlled shop use. AIRCAT also lists a multi-positional rotational guard to improve access, a composite grip and throttle trigger designed for operator comfort, and a 360° rotational exhaust that helps direct exhaust flow away from the work area.
