Alpha PWC Pneumatic Wet Cutter/Grinder (6")

Alpha® PWC Pneumatic Wet Cutter/Grinder — 5" & 6" Industrial Stone ToolThe Alpha® PWC series is a purpose-built, industrial-grade pneumatic wet cutter/grinder designed from the ground up for stone fabrication — not a converted dry grinder with a bolt-on water line. Its Quad-W center water-feed adapter delivers water to both sides of the blade for clean cuts and flat grinding, while a reversible safety guard, L-bracket and side handle let you configure the tool for left or right blade position, push-to-cut, or pull-to-cut work. Built on more than 35 years of Alpha wet-tool engineering and backed by a one-year tool warranty.

Always install an Alpha Filter/Regulator Manifold upstream to keep humidity and debris out of the motor. Add several drops of Rust Inhibitor Oil through the oil port at the end of every shift; spin the spindle a few turns to coat the cylinder and rotor. Mount the Alpha Elite Q blade (included) using the Quad-W Adapter for cutting; use the Katana Q blade for porcelain or sintered slabs. For dry cutting/grinding under OSHA Table 1, swap the steel safety guard for an Alpha Ecoguard CX, W6 or GX and connect a HEPA vacuum. Replace mufflers when you notice power loss — clogged exhaust is the most common cause.

What can I do?You probably have multiple tools sharing the airline. Each PWC needs a steady 33 CFM at 90 PSI; isolate the tool, shorten the airline, or upsize the supply to restore performance. How is the PWC different from a regular pneumatic angle grinder?Most "wet" pneumatic grinders on the market are dry tools with a bolt-on water feed. The Alpha PWC is engineered from scratch as a wet industrial stone tool, drawing on 35+ years of Alpha wet-polisher development. How do I cut with the PWC?Use the included Quad-W Adapter, which feeds water to both sides of the blade. The Quad-W is standard equipment and is also sold separately through Alpha distributors. What is the warranty?One year on the tool. Full terms are printed in the operator’s manual. Can I run the PWC dry?Yes — for dry cutting or grinding, replace the steel safety guard with an Alpha Ecoguard CX, W6 or GX and connect a HEPA vacuum to capture silica dust per OSHA Table 1. What is the best long-term maintenance routine?Always run the PWC downstream of an Alpha Filter/Regulator Manifold to remove humidity and debris. At the end of every shift, add a few drops of Rust Inhibitor Oil through the oil port and turn the spindle a few revolutions to coat the cylinder and rotor. Should I use an automatic oiler?No. Auto-oilers soak the muffler with dirty oil (causing clogs and power loss), spray oil onto the stone (staining), and make the floor slippery. Daily manual oiling is the recommended method. I have lost power even though my settings are unchanged. How do I fix it?The muffler is most likely clogged. Remove the exhaust deflector with a screwdriver and replace it — you can also rotate it to redirect the exhaust away from the operator. How do I change the angle of the spring-return throttle lever?Use a 48 mm spanner to loosen Nut Part No. 60, rotate the lever to the desired position, and re-tighten. Which blade should I use on porcelain or sintered slab?Switch from the included Elite Q (granite / quartzite / engineered stone) to the Alpha Katana Q, which is purpose-built for porcelain and sintered slabs.
