Shaped to the B53 cone profile, this mounted point features an 80-grit coarse abrasive with a resinoid bond and medium density for consistent stock removal on ferrous and non-ferrous metals. The 1\/8-inch shank mounts directly into standard die grinders, rotary tools, and flexible shaft machines. It is rated to a maximum of 60,000 RPM, making it suited for high-speed finishing applications. Machinists, tool and die makers, and fabricators rely on this type of abrasive for weld cleanup, port blending, and mold work.\u003c\/p\u003e\n\u003cp\u003eThis mounted point is used in industrial and job-shop environments where a small, high-speed abrasive is needed to reach internal bores, cavities, and irregular contours. The B53 cone shape is effective for working chamfers, radii, and recessed surfaces. At 2 inches overall length with a 1-1\/2-inch shank, it provides adequate reach without excessive overhang. Applications include deburring castings, cleaning weld seams, and preparing metal surfaces before finishing. It is sold individually and is appropriate for both production floor and field maintenance use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eB53 cone point shape for access to contoured and recessed surfaces\u003c\/li\u003e\n  \u003cli\u003e80-grit coarse aluminum oxide abrasive for efficient stock removal\u003c\/li\u003e\n  \u003cli\u003eResinoid bond with medium density for consistent cut and durability\u003c\/li\u003e\n  \u003cli\u003eRated to 60,000 RPM for use with high-speed die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch shank diameter fits standard collets on most rotary and die grinder tooling\u003c\/li\u003e\n  \u003cli\u003e2-inch overall length with 1-1\/2-inch shank provides reach into deep cavities\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with die grinders, rotary tools, and flexible shaft machines equipped with a 1\/8-inch collet.

Insert the shank fully into the collet and tighten securely before operation. Always verify the tool RPM rating meets or is below the 60,000 RPM maximum marked on this abrasive. Inspect the mounted point for cracks or chips before each use and discard any damaged points immediately.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: Cone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Shape Code\u003c\/strong\u003e: B53\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: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDensity\/Hardness\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Pink\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 60,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: MERIT ABRASIVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69078645340\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51557920997682,"sku":"69078645340","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd416410dde7410a1b2f3d380020a19e.jpg?v=1786398421","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-69078645340-mounted-point-b53-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
