About This Product
High-Performance Pneumatic Stone Cutters and Grinders
Alpha® PWC Pneumatic Stone Cutters/Grinders are high-speed air-powered tools for wet cutting and flat grinding stone. Designed for fabrication work, the PWC Series combines angle-grinder-style handling with up to 1.4 HP and a center water-feed system for cutting and grinding applications.
Center Water Feed for Wet Cutting and Grinding
The Quad W Adapter directs water to both the front and back sides of the cutting blade. The center-feed design also supplies water during flat grinding, allowing the same pneumatic grinder to support multiple fabrication operations while controlling water at the working area.
Push-to-Cut and Pull-to-Cut Configurations
A reversible safety guard supports left- or right-side blade positioning. The included L-bracket and side handle configure the air stone cutter for pull-to-cut operation, while the side handle can be repositioned for push-to-cut applications.
Two PWC Configurations with Complete Accessory Packages
The PWC-658 accepts discs up to 6", operates at 10,000 RPM, and has a 5/8"-11 spindle. The PWC-514 accepts discs up to 5", operates at 12,000 RPM, and uses an M14-2 spindle. Both pneumatic stone cutter/grinder configurations include a 30 ft. air/water twin hose, matching Alpha® Elite Q Blade, Quad W Adapter Assembly, safety guard, handles, maintenance accessories, and reusable stackable toolbox.

Common Questions
Frequently Asked Questions
Can Alpha PWC Pneumatic Stone Cutters/Grinders cut and grind?
Yes. Both PWC models support wet stone cutting and flat grinding. The center water-feed system supplies water during either operation.
How does the Quad W center water-feed system work?
The Quad W Adapter directs water to the front and back sides of the cutting blade. It also supplies center-fed water during flat grinding applications.
What is the difference between the PWC-658 and PWC-514?
The PWC-658 accepts discs up to 6", operates at 10,000 RPM, and has a 5/8"-11 spindle. The PWC-514 accepts discs up to 5", operates at 12,000 RPM, and uses an M14-2 spindle.
Can PWC Air Stone Cutters be configured for push-to-cut and pull-to-cut operation?
Yes. The L-bracket and side handle support pull-to-cut operation, while the side handle can be repositioned for push-to-cut applications.
Can the cutting blade be positioned on either side of the tool?
Yes. The reversible safety guard accommodates left- or right-side blade positioning.
What air supply do the PWC Pneumatic Grinders require?
