The carbide head delivers hardness and heat resistance needed for extended tool life under high-speed operation, with a maximum rated speed of 40,000 RPM. The 3\/16-inch shank diameter pairs with standard die grinder collets and rotary tool chucks, making this bur a straightforward fit for most portable and bench-mounted rotary tools. Licensed tradespeople and machinists reach for this style of bur when a guided cut or controlled entry point is required.\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. The cylinder-with-pilot configuration is particularly useful in weld prep, porting, surface blending, and deburring of drilled or bored holes where the pilot keeps the bur tracking true. It is appropriate for both production-floor and maintenance-repair applications across metalworking, fabrication, automotive, and industrial trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble cut tooth style for faster stock removal and a smoother surface finish than single cut\u003c\/li\u003e\n  \u003cli\u003eCarbide head construction handles steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys\u003c\/li\u003e\n  \u003cli\u003eCylinder-with-pilot head shape provides guided entry for controlled deburring and porting work\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 40,000 RPM compatible with standard high-speed die grinders\u003c\/li\u003e\n  \u003cli\u003eUncoated carbide head — no coating to chip or peel under heavy cuts\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch shank fits common die grinder and rotary tool collet sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement bur conforming to industry specification PDM-01DC, compatible with die grinders and rotary tools accepting a 3\/16-inch shank collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tool operators familiar with rotary abrasive tooling. Before mounting, confirm the tool spindle is fully stopped and the power source is disconnected or the air supply is shut off. Verify collet size matches the 3\/16-inch shank before tightening, and do not exceed the 40,000 RPM maximum rated speed. Always wear appropriate eye protection and follow applicable OSHA and ANSI B11 standards when operating rotary burring tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Specification\u003c\/strong\u003e: PDM-01DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Cylinder with Pilot\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: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 40,000\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: 2.95 inches L x 0.39 inches W x 0.39 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 7466391\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51692384059698,"sku":"7466391","price":45.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/923b614da0be43aaf1e73f4dd8d1a2be.jpg?v=1788296968","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-7466391-carbide-abrasive-bur","provider":"Voomi Supply","version":"1.0","type":"link"}
