It is designed for aggressive material removal and surface finishing on metal workpieces in fabrication, maintenance, and tool-and-die applications. The 1\/2-inch cutting diameter and 1-inch length of cut allow efficient stock removal in a single pass, while the double-cut tooth pattern reduces chatter and clears chips faster than single-cut geometry. The 1\/4-inch shank fits standard die grinders and rotary tools. Machinists, pipefitters, and fabricators use this bur for deburring, blending welds, porting, and shaping hard materials.\u003c\/p\u003e\n\u003cp\u003eThis bur is suited for use on steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and other hard materials. It performs in both handheld die grinder setups and bench-mounted rotary applications. Typical use cases include weld prep, port matching, cavity deburring, and contour blending in manufacturing and heavy fabrication environments. The uncoated carbide head maintains cutting edge integrity across a wide range of ferrous and non-ferrous workpiece materials without the risk of coating delamination at elevated surface speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-cut tooth style for faster stock removal and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eSolid carbide head rated for steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and hard materials\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch cutting diameter with 1-inch length of cut for substantial contact area\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank diameter compatible with standard die grinder collets\u003c\/li\u003e\n  \u003cli\u003eRated to 25,000 RPM for use with high-speed rotary tools\u003c\/li\u003e\n  \u003cli\u003eConforms to SA-50DC industry specification for consistent head geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for 1\/4-inch shank die grinders and rotary tools requiring a double-cut carbide cylinder bur meeting the SA-50DC industry specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, fabricators, or maintenance technicians using a standard die grinder with a 1\/4-inch collet. Ensure the die grinder is fully powered down and depressurized before inserting or removing the bur. Seat the shank fully into the collet and tighten to the tool manufacturer's specification before operation. Always wear appropriate eye protection and ensure the workpiece is secured before engaging the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Specification\u003c\/strong\u003e: SA-50DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Cylinder with Flat End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Style\u003c\/strong\u003e: Double Cut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.7500 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\u003eHead Material\u003c\/strong\u003e: 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: 25,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metals, High-Temperature Alloys, Hard Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.76 inches L x 0.67 inches W x 0.67 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.126 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7466216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51697208197426,"sku":"7466216","price":45.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3954e3af3e30e56bc68f3118b1515d07.jpg?v=1788350554","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-7466216-carbide-abrasive-bur-sa-50dc","provider":"Voomi Supply","version":"1.0","type":"link"}
