The ST-235 was designed specifically for the demands of a fabrication shop: wet environment, high cycles, full grit progression from 50 through 3,000. It runs at 5,000 RPM at 90 PSI \/ 16 CFM with a 5\/8-11 arbor for complete compatibility with standard diamond polishing pad systems.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eSpecs and Features\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\"\u003e5,000 RPM at 90 PSI \/ 16 CFM - right in the range for granite edge polishing\u003c\/li\u003e\n\u003cli dir=\"ltr\"\u003e5\/8-11 arbor thread - compatible with all standard diamond polishing pads and backer systems\u003c\/li\u003e\n\u003cli dir=\"ltr\"\u003eBuilt-in brass lubrication port - oil directly into the motor without disassembly; keeps the motor running at full power over time\u003c\/li\u003e\n\u003cli dir=\"ltr\"\u003eIntegrated water fittings - standard pneumatic and water connections; ships with hoses included\u003c\/li\u003e\n\u003cli dir=\"ltr\"\u003eAdjustable handle - sets to right or left-handed grip for working different edge profiles\u003c\/li\u003e\n\u003cli dir=\"ltr\"\u003eEasy-grip, ambidextrous on\/off twist knob\u003c\/li\u003e\n\u003cli dir=\"ltr\"\u003eParts and repairs readily available - no waiting months for a replacement component\u003c\/li\u003e\n\u003cli dir=\"ltr\"\u003e1-year warranty against manufacturing defects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv dir=\"ltr\"\u003e\u003cstrong\u003eBuilt for Professional Fabrication\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv dir=\"ltr\"\u003ePneumatic tools run cleaner in wet shop environments than electric.
