Alpha® PSC-150 / PSC-600 6" Pneumatic Stone CutterThe Alpha® PSC family delivers industrial-grade pneumatic cutting for stone fabrication shops. The PSC-150 (2 HP) pairs a torque-sensing speed governor with a 6" Eclipse II diamond blade to miter cut 1-1/4" (3 cm) material in a single pass — ideal for sink-hole cuts, groove cutting and rodding on granite and engineered quartz. The lighter PSC-600 is a compact 6" wet cutter/grinder with a center water-feed system that cools both sides of the blade, switching between cutting and grinding modes with a flange swap. Both run on standard shop air and ship turn-key with 15 ft (4.5 m) all-weather hoses.Features PSC-150: 2 HP pneumatic motor with speed-control governor; PSC-600: compact 15 CFM cutter/grinder PSC-150 miter cuts 1-1/4" (3 cm) material in a single pass; PSC-600 doubles as a wet stone grinder with flange swap 6" (150 mm) disc diameter with 7/8" (22.23 mm) arbor on both models No-load speed 8,500 RPM — matched to Eclipse II and Plus diamond blades Kink-free water and air hoses (15 ft / 4.5 m) for shop or jobsite use Can be used wet or dry — pair with HEPA dust collection for OSHA Table 1 compliance PSC-150 ships with Eclipse II 6" Blade (DEE006) and Rust Inhibitor Oil (AIR-008) PSC-600 includes both cutting and grinding flanges plus L-bracket; one-year tool warranty on both .dst-accordion { margin-top: 25px; border: 1px solid #FDDCC5; border-radius: 6px; overflow: hidden; } .dst-accordion-item { border-bottom: 1px solid #FDDCC5; } .dst-accordion-item:last-child { border-bottom: none; } .dst-accordion-toggle { display: none; } .dst-accordion-label { display: flex; justify-content: space-between; align-items: center; padding: 14px 20px; cursor: pointer; font-size: 17px; font-weight: 700; color: #231F20; background: #fff; transition: background 0.2s; } .dst-accordion-label:hover { background: #FFF3EB; } .dst-accordion-label::after { content: '+'; font-size: 22px; font-weight: 700; color: #F15C22; transition: transform 0.3s; } .dst-accordion-toggle:checked + .dst-accordion-label { background: #FFF3EB; } .dst-accordion-toggle:checked + .dst-accordion-label::after { content: '\2212'; } .dst-accordion-content { max-height: 0; overflow: hidden; transition: max-height 0.4s ease; padding: 0 20px; background: #fff; } .dst-accordion-toggle:checked ~ .dst-accordion-content { max-height: 5000px; padding: 15px 20px 20px; } Models / Part Numbers Part No. Power Disc Size Air Consumption UPC PSC-150 2.0 HP 6" (150 mm) 32-48 CFM 749173621390 PSC-600 Pneumatic (15 CFM) 6" (150 mm) 15 CFM 749173430107 How to Use Connect the tool to a properly sized compressor: PSC-150 needs up to 32-48 CFM (industrial rotary screw or 7.5+ HP recommended); PSC-600 needs 15 CFM minimum. Hook up the included 15 ft water hose to a standard garden supply via the quick coupler with shut-off; confirm steady flow at the manifold. For PSC-600 grinding mode, swap the inner flange to the grinding version so all water is directed to the grinding edge (grinding wheels require the 7/8" straight arbor). Mount the side handle in the position that gives the best comfort and cut stability. Set blade depth and ride the cut on an Alpha® Guide Rail with ASC-6CSM Carriage for repeatable straight cuts, or free-hand for curves and sink-holes. Advance the cutter steadily — let the blade do the work; do not force sideways. After each shift, add a few drops of AIR-008 rust inhibitor oil at the designated port and slowly introduce air pressure to lubricate the motor. Periodically clean or replace the muffler to keep noise down and maintain rated performance.

Plan on an industrial rotary screw compressor (minimum 7.5 HP) sized for maximum torque applications.Can the PSC-600 be used as a grinder?Yes. Swap the inner flange from the cutting version to the grinding version so all water is directed to the grinding edge. Grinding wheels require the 7/8" straight arbor — not 5/8"-11.Can I use the PSC at the jobsite?Yes. As long as you have the required compressed air available, you can run the PSC-150 or PSC-600 on the jobsite. Diesel-engine air compressors built for jackhammers typically deliver enough capacity.Can I use the PSC as a dry stone cutter?Yes, but Alpha® recommends wet cutting to keep dust down and reduce silica exposure. If you cut dry, pair the tool with a HEPA dust-collection system per OSHA Table 1.What maintenance does the PSC need?Add a few drops of AIR-008 rust inhibitor oil at the designated oil port at the end of every shift and slowly introduce air pressure to lubricate the motor. Periodically clean or change the muffler to keep noise down.Why does the PSC-150 list both CFM and SCFM?The PSC-150 has a torque-sensing speed governor in the motor that regulates air consumption based on the load. At no load it draws only 4.6 CFM; under heavy cutting the governor opens up to 32.8 CFM at the 2.0 HP maximum.How do I get the parts list or schematic?Visit alpha-tools.com or call 800-648-7229 to request the parts list and schematic for either model.
