It carries a Type 27 and Type 42 profile, making it compatible with standard right-angle grinders. The wheel measures 4.5 inches in diameter and 0.09375 inches thick, with a 0.875-inch arbor hole. Its ceramic abrasive grain delivers an extra coarse cut, and the resinoid bond holds the grain firmly under high-load grinding. Maximum rated speed is 13,300 RPM. Licensed trades and metal fabricators rely on this wheel for weld grinding, surface conditioning, and stock removal on ferrous and non-ferrous workpieces.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for use in metal fabrication shops, industrial maintenance, and field welding applications. The Type 27 depressed-center design keeps the grinding surface at a low angle to the workpiece, which is preferred for flat surface work and weld flush grinding. The Type 42 geometry also allows conical-profile use where edge access is needed. Installation on standard 4.5-inch right-angle grinders with a 7\/8-inch arbor is straightforward, and the black resinoid wheel body provides visual wear indication during use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain provides aggressive, fast stock removal on hard metals\u003c\/li\u003e\n\u003cli\u003eExtra coarse grade for heavy grinding and weld removal applications\u003c\/li\u003e\n\u003cli\u003eRated to 13,300 RPM for use with standard right-angle grinders\u003c\/li\u003e\n\u003cli\u003eType 27 and Type 42 dual-profile compatibility in a single wheel\u003c\/li\u003e\n\u003cli\u003eResinoid bond maintains grain retention under sustained grinding pressure\u003c\/li\u003e\n\u003cli\u003e7\/8-inch arbor hole fits the most common grinder spindle standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 4.5-inch right-angle grinders accepting a 7\/8-inch arbor, conforming to Type 27 and Type 42 wheel mount specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and disconnect the grinder before mounting or removing the wheel. Verify the grinder spindle speed does not exceed the 13,300 RPM rating marked on the wheel before starting. Inspect the wheel for cracks or chips before each use and do not use a damaged wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.09375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size (Arbor)\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 27 and Type 42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.38 inches x 5.2 inches x 5.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100141055\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51692976046386,"sku":"7100141055","price":273.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d8a0e7d22f38b55feae5f6cb0c86006.jpg?v=1788305726","url":"https:\/\/voomisupply.com\/products\/3m-7100141055-depressed-grinding-wheel-type-27-type-42","provider":"Voomi Supply","version":"1.0","type":"link"}
