It measures 0.1094 inches (7\/64 inch) in diameter with an overall length of 1-13\/16 inches and a flute length of 13\/16 inches. The bit is manufactured from high speed steel with a coated finish, features a 135-degree split point, and uses a straight-cylindrical shank for secure chuck retention. The web-thinned, tapered web design reduces thrust and improves centering on hard materials. This bit is suited for machinists, tool and die workers, and production drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe 060407 is built for drilling precipitation-hardened steels and superalloys, making it a practical choice in machine shops, maintenance environments, and production lines where short-length rigidity is required. The screw machine length format provides extra stiffness compared to jobber-length bits, reducing deflection in tight-tolerance hole applications. Right-hand spiral flute geometry promotes efficient chip evacuation in ferrous and high-strength alloy workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1094 inch (7\/64 inch) diameter, screw machine length for added rigidity\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with coated finish for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering and reduced walking on hard stock\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers thrust requirements in tough alloys\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute geometry for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling precipitation-hardened steel and superalloy workpieces; rated for the 0.1000 to 0.1500 inch drill bit size range within the Series T4HD heavy-duty screw machine length family.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and operated by machinists and tool and die professionals using standard drill presses, CNC machines, or hand-held power drills with compatible chucks. Secure the straight-cylindrical shank fully in the chuck before operation and verify runout before drilling hard alloys. Coolant-through is not supported on this bit, so apply cutting fluid externally when drilling superalloys or hardened steels to manage heat buildup. Do not exceed the recommended feed and speed parameters for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1094 inches (7\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.8125 inches (13\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: PH Steel, Superalloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T4HD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: TRIUMPH TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 060407\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67916646908210,"sku":"060407","price":37.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/127e0b36d3ea997b142e928a377d04d2.jpg?v=1791258748","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-060407-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
