It accepts a 4-inch cutting wheel and spins at 14,000 RPM, delivering the speed needed to cut through sheet metal, pipe, and structural steel efficiently. Air supply connects through a 1\/4-inch inlet, and exhaust exits at the rear to keep debris directed away from the operator. At 3.7 pounds, the tool is light enough for extended use without excessive fatigue. Licensed trades and skilled mechanics rely on this class of tool for precision cutoff work where an angle grinder or die grinder is not suited.\u003c\/p\u003e\n\u003cp\u003eThis cutoff grinder fits well in automotive shops, HVAC fabrication, plumbing rough-in, and general metal fabrication settings. The right-angle handle positions the cutting wheel perpendicular to the tool body, which is the standard configuration for flush cuts, pipe notching, and access in tight spaces. It requires a compressed air source capable of delivering 90 psi and 4.00 SCFM. Any shop compressor sized for pneumatic tool use should meet those requirements without issue.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch wheel diameter for standard cutoff wheel compatibility\u003c\/li\u003e\n  \u003cli\u003e14,000 RPM free speed for fast, clean metal cuts\u003c\/li\u003e\n  \u003cli\u003eRight-angle handle for flush cuts and tight-space access\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch air inlet fits common pneumatic quick-connect fittings\u003c\/li\u003e\n  \u003cli\u003eRear exhaust directs spent air away from the work surface\u003c\/li\u003e\n  \u003cli\u003e3.7-pound tool weight reduces operator fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 4-inch pneumatic cutoff wheels.

Always depressurize the air line and verify the tool is disconnected from the air supply before mounting or changing a cutting wheel. Inspect the wheel for cracks or damage before each use and never exceed the wheel manufacturer's maximum RPM rating. Eye protection, hearing protection, and appropriate gloves are required during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Speed\u003c\/strong\u003e: 14,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Pressure\u003c\/strong\u003e: 90 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 4.00 SCFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Right Angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Rear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.7 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHICAGO PNEUMATIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8941091161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO PNEUMATIC","offers":[{"title":"Default Title","offer_id":51541658370354,"sku":"8941091161","price":557.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c155ead67ae0b06129b3434d716c537.jpg?v=1785881363","url":"https:\/\/voomisupply.com\/products\/chicago-pneumatic-8941091161-pneumatic-cutoff-grinder","provider":"Voomi Supply","version":"1.0","type":"link"}
