The ball-shaped cutting head measures 7\/16 inch in diameter and mounts on a 1\/4 inch diameter shank. The single-cut tooth style produces a smooth surface finish with efficient chip clearance, making it well suited for work on steel, cast iron, aluminum, and similar hard materials. Uncoated solid carbide construction provides durability and dimensional stability under high-speed operation.\u003c\/p\u003e\u003cp\u003eThis bur is used in die grinding, port matching, weld cleanup, and general metalworking tasks. It is commonly run in pneumatic or electric die grinders fitted with a 1\/4 inch collet. The ball profile is particularly effective in contoured or recessed areas where flat or cylindrical profiles cannot reach. Machinists, tool-and-die makers, pipefitters, and fabricators are the primary installers and operators of this type of bur.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBall head profile for contouring, blending, and working in concave or recessed surfaces\u003c\/li\u003e\n\u003cli\u003e7\/16 inch cutting diameter for moderate material removal in tight areas\u003c\/li\u003e\n\u003cli\u003e1\/4 inch shank diameter fits standard die grinder collets\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for extended tool life on hard metals\u003c\/li\u003e\n\u003cli\u003eSingle-cut tooth style for smooth finish and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eUncoated head — no coating delamination risk during heavy use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement carbide bur for use in standard die grinders and rotary tools accepting a 1\/4 inch shank, conforming to SD-4 industry specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or fabricators using a die grinder with a properly sized 1\/4 inch collet. Ensure the grinder is fully depowered and unplugged before inserting or removing the bur. Inspect the shank for runout or damage before each use, and do not exceed the grinder manufacturer's maximum rated RPM for this shank diameter. Eye protection and appropriate hand protection are required when operating carbide burs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Specification\u003c\/strong\u003e: SD-4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTooth Style\u003c\/strong\u003e: Single Cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0495 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SZ0020B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735269769522,"sku":"SZ0020B","price":33.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/765bac6077f78e5c03c2c8a63684a67b.jpg?v=1788771274","url":"https:\/\/voomisupply.com\/products\/hertel-sz0020b-abrasive-bur-ball-7-16-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
