Alpha PWC-658 Pneumatic Cutter Grinder

The Alpha PWC-658 is a high-speed pneumatic angle cutter and grinder designed for stone fabrication. Its quad-adapter center water-feed system directs water to both the front and back of the blade, supporting cutting and flat-grinding applications.

A reversible safety guard accommodates left- or right-side blade positioning. The included L-bracket and side-handle setup supports the pull-to-cut method, while the side handle can also be configured for push-to-cut operation.

The spring-return throttle helps prevent accidental startup, and an easily accessible oil port simplifies daily maintenance.
