The point features a ball-shaped head with a 0.156-inch head diameter and 0.25-inch head thickness, mounted on a 0.25-inch diameter shank with a 3-inch overall length. At 200\/230 grit, it falls in the fine grade range, making it well-suited for finishing passes and detail work where surface quality matters. It weighs 0.3 pounds and is sold individually.\u003c\/p\u003e\u003cp\u003eThis mounted point is used in die grinder and rotary tool applications across toolroom, maintenance, and production environments. It is appropriate for hand-held or bench-mounted spindle work on molds, dies, ports, and contoured surfaces. The ball shape allows access to curved recesses and concave profiles that flat or cylindrical points cannot reach. It is commonly used by machinists, tool-and-die workers, and maintenance technicians working with hard or brittle workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eElectroplated diamond abrasive for consistent cut on hard materials including carbide and ceramics\u003c\/li\u003e\n\u003cli\u003eBall point shape (Shape Code 4156FD) for grinding curved recesses and concave surfaces\u003c\/li\u003e\n\u003cli\u003e200\/230 grit fine grade for finishing and light stock removal\u003c\/li\u003e\n\u003cli\u003e0.25-inch shank diameter fits standard die grinder collets\u003c\/li\u003e\n\u003cli\u003e3-inch overall length provides reach into restricted work areas\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit die grinders and rotary tools accepting a 0.25-inch shank.

Inspect the mounted point for cracks or loose bonding before mounting, and never exceed the rated RPM marked on the point or packaging. Secure the shank fully in the collet before operation and ensure the workpiece is properly fixtured. Always wear appropriate eye protection and follow ANSI B7.1 guidelines for abrasive tool use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 200\/230\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape Code\u003c\/strong\u003e: 4156FD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.156 inches\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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191602\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66260392629\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542886416690,"sku":"66260392629","price":109.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fb78016bacc3eebeedd98bc2c259fec.jpg?v=1785909970","url":"https:\/\/voomisupply.com\/products\/norton-66260392629-diamond-mounted-point-ball-200-230-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
