The cutting head measures 0.375 inches in diameter with a 0.75-inch length of cut, mounted on a 0.25-inch shank. Rated to 37,500 RPM, this bur delivers aggressive stock removal on ferrous and non-ferrous metals, aluminum, and hard plastics. The uncoated tungsten carbide head provides the hardness needed for repeated use in demanding shop environments. Machinists, tool grinders, and fabricators typically reach for this style of bur for contour work and cavity finishing.\u003c\/p\u003e\n\u003cp\u003eThis cylinder ball end bur is suited for die grinding in production and maintenance settings. The ball end profile allows access to concave surfaces, slots, and blind cavities where flat-end or tapered burs cannot follow the geometry. The 2.5-inch overall length gives adequate reach for most rotary tool and air die grinder chucks. It is appropriate for use on ferrous metals, cast iron, steel alloys, and hard plastics in both shop and field service scenarios. Industry specification cross-reference is SE-51G D\/C.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-cut flute pattern for fast material removal and reduced chatter on metal surfaces\u003c\/li\u003e\n  \u003cli\u003eCylinder ball end geometry for contouring, blending, and cavity work\u003c\/li\u003e\n  \u003cli\u003eTungsten carbide head for long service life on hard materials\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 37,500 RPM compatible with most air die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003e0.25-inch shank fits standard die grinder and rotary tool collets\u003c\/li\u003e\n  \u003cli\u003eUncoated head maintains consistent cutting geometry without coating buildup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with die grinders and rotary tools accepting a 0.25-inch shank collet.

Always confirm the grinder RPM rating meets or exceeds the bur maximum of 37,500 RPM before operation. Secure the workpiece firmly before grinding to prevent movement. Wear appropriate eye protection and gloves in accordance with applicable shop safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Cylinder Ball End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Style\u003c\/strong\u003e: Double Cut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Material\u003c\/strong\u003e: Tungsten Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 37,500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Specification\u003c\/strong\u003e: SE-51G D\/C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\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: SGS PRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SGS PRO","offers":[{"title":"Default Title","offer_id":51971408298290,"sku":"19211","price":37.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23a59ac86737876a83fa79b68a6b9234.jpg?v=1789956963","url":"https:\/\/voomisupply.com\/products\/sgs-pro-19211-cylinder-ball-end-abrasive-bur-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
