It measures 4.5 inches in diameter with a 7\/8 inch arbor hole and carries a resinoid bond with 36-grit aluminum oxide abrasive. The A36-X-FLEX specification indicates a flexible, high-performance bond matrix that allows the wheel to conform slightly under load, reducing gouging and improving surface contact. Rated to 13,300 RPM maximum, it suits most 4.5 inch angle grinders used in metal fabrication, structural work, and maintenance trades. The black resinoid-bonded construction handles heat and vibration typical of sustained grinding passes.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for grinding aluminum, non-ferrous metals, stainless steel, and carbon steel. It is a practical choice for fabricators, ironworkers, pipefitters, and maintenance technicians who need a single wheel capable of crossing material types on a job site. The Type 29 geometry  -  a conical depressed-center profile  -  provides a low angle of attack that improves surface coverage compared to a flat Type 1 wheel, making it well suited for weld blending, deburring, and surface conditioning on flat and contoured workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 29 conical profile for improved surface contact and weld blending\u003c\/li\u003e\n\u003cli\u003e36-grit aluminum oxide abrasive for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eA36-X-FLEX resinoid bond for flexibility and reduced gouging under load\u003c\/li\u003e\n\u003cli\u003e13,300 RPM maximum speed rating compatible with standard 4.5 inch angle grinders\u003c\/li\u003e\n\u003cli\u003e7\/8 inch arbor hole fits standard angle grinder spindle arbors\u003c\/li\u003e\n\u003cli\u003eRated for aluminum, non-ferrous metals, stainless steel, and carbon steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with angle grinders accepting a 4.5 inch diameter, 7\/8 inch arbor grinding wheel.

Inspect the wheel for cracks or chips before mounting  -  never use a damaged wheel. Ensure the grinder spindle speed does not exceed the 13,300 RPM maximum marked on the wheel, and always use the guard provided with the tool. Wheel mounting and angle grinder use in occupational settings is subject to ANSI B7.1 and OSHA 1910.215 requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 29 Depressed Center\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 0.875 inches (7\/8 inch arbor)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Grade\u003c\/strong\u003e: A36-X-FLEX\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\u003eTool Compatibility\u003c\/strong\u003e: Angle Grinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Non-Ferrous Metals, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.71 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER SURFACE TECHNOLOGIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 15L463\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67906532966706,"sku":"15L463","price":287.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c882172e3005b895159b8e62a2c2a73e.jpg?v=1791168889","url":"https:\/\/voomisupply.com\/products\/walter-surface-technologies-15l463-type-29-grinding-wheel","provider":"Voomi Supply","version":"1.0","type":"link"}
