It measures 0.875 inches in maximum diameter and 1.25 inches in length, with a 0.25-inch arbor hole for use with rotary tools, die grinders, and flexible shaft machines. The abrasive matrix is silicon carbide at a coarse grade (36 grit), making it well-suited for aggressive stock removal and fast cutting on ferrous and non-ferrous metals, ceramics, and hard plastics. This is an unmounted point, sold individually, rated to a maximum of 20,000 RPM.\u003c\/p\u003e\n\u003cp\u003eRubberized abrasive points like the CRATEX 1357 C are used in tool and die shops, maintenance and repair operations, and production finishing environments. The cone geometry allows access to internal contours, holes, slots, and curved surfaces where flat or cylindrical abrasives cannot reach. Typical applications include cleaning up weld seams, chamfering bolt holes, smoothing casting flash, and blending machined surfaces. It is commonly used by machinists, tool and die makers, and metal fabricators working with benchtop or handheld rotary equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCone shape for access to contoured surfaces, internal radii, and recessed areas\u003c\/li\u003e\n  \u003cli\u003eSilicon carbide abrasive matrix provides fast, aggressive cutting action\u003c\/li\u003e\n  \u003cli\u003eCoarse grade (36 grit) suited for rapid stock removal and deburring\u003c\/li\u003e\n  \u003cli\u003eRubberized bond offers some flexibility, reducing chipping risk on intricate workpieces\u003c\/li\u003e\n  \u003cli\u003eUnmounted design fits standard 0.25-inch arbor collets on die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003eRated to 20,000 RPM for use with high-speed rotary equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with rotary tools, die grinders, and flexible shaft machines fitted with a 0.25-inch collet or mandrel.

Verify that the tool spindle speed does not exceed the 20,000 RPM rating of this point. Always wear appropriate eye protection and secure the workpiece before grinding. Inspect the abrasive point for cracks or damage before each use and discard if the bond shows signs of deterioration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Cone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounted\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: CRATEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1357 C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRATEX","offers":[{"title":"Default Title","offer_id":67909212602674,"sku":"1357 C","price":32.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9152c38d097bf73c717362d16935fc1a.jpg?v=1791185818","url":"https:\/\/voomisupply.com\/products\/cratex-1357-c-rubberized-abrasive-cone-point-coarse-silicon-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
