Built with aluminum oxide grain bonded in a unitized, very hard bond, this mounted point delivers consistent stock removal and shape retention through extended use cycles. It fits a 1\/8-inch shank and spins safely at up to 51,750 RPM, making it suitable for use in die grinders and rotary tools across production and maintenance grinding applications. The coarse grade removes material aggressively, and the green aluminum oxide composition holds up well against ferrous metals and hard alloys.\u003c\/p\u003e\u003cp\u003eThis mounted point is used in tool and die work, weld cleanup, mold finishing, and general grinding tasks where a small-diameter abrasive point is needed to access tight geometry or internal surfaces. It is appropriate for both shop-floor production environments and maintenance repair operations. Trades that commonly use this type of abrasive include machinists, fabricators, and maintenance mechanics working with steel, cast iron, and similar hard metals. The cylinder profile suits flat-bottom grinding and side-wall finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCylinder point shape (W183 designation) for flat-bottom and side-wall grinding\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive grain for efficient stock removal on ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003eCoarse grade for aggressive material removal\u003c\/li\u003e\n\u003cli\u003eVery hard bond density for shape retention and extended wheel life\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter compatible with standard die grinders and rotary tools\u003c\/li\u003e\n\u003cli\u003eRated to 51,750 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use mounted point for die grinders and rotary tools accepting a 1\/8-inch shank collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounted points are installed by licensed machinists, fabricators, or maintenance mechanics using a die grinder or compatible rotary tool with a matching 1\/8-inch collet. Always confirm the tool's rated RPM meets or exceeds the mounted point's 51,750 RPM maximum before use. Inspect the point for cracks or chips before mounting, and never exceed the marked maximum speed. Secure the shank fully into the collet and tighten per the tool manufacturer's specifications before operating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: Cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape Code\u003c\/strong\u003e: W183\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\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: Unitized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDensity\/Hardness\u003c\/strong\u003e: Very Hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.25 inches\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\u003eMaximum RPM\u003c\/strong\u003e: 51,750\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Green\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.006 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131514\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GRIER ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W183-N4-17569\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GRIER ABRASIVES","offers":[{"title":"Default Title","offer_id":67914914300210,"sku":"W183-N4-17569","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d439606b5dde3ec951083a6773de5256.jpg?v=1791251546","url":"https:\/\/voomisupply.com\/products\/grier-abrasives-w183-n4-17569-mounted-point-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
