It measures 15\/32 inch (0.4688 inches) in diameter with an overall length of 3-5\/8 inches and a spiral flute length of 2.125 inches. The bit is manufactured from high speed steel with a coated finish to extend cutting life under hard-use conditions. A 135-degree split point reduces walking on entry and lowers the thrust needed to start a hole. Web thinning with a tapered web configuration further improves cutting efficiency. This bit is part of the T4HD series and is intended for installation by machinists and skilled trades professionals working with precision drilling equipment.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in screw machine or stub-length drilling setups where reduced bit overhang and improved rigidity are required. Its primary workpiece material rating is superalloy, making it suitable for aerospace, industrial, and heavy fabrication environments where standard bits fall short. The right-hand spiral flute design evacuates chips efficiently during through-hole and blind-hole drilling operations. At 0.78 pounds, it is a single-piece unit packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15\/32 inch (0.4688 inches) diameter, sized within the 0.4500 to 0.5000 inch heavy-duty range\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces entry walking and decreases required feed pressure\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration improves cutting efficiency and chip clearance\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 3-5\/8 inches overall for improved rigidity in close-tolerance work\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute  -  compatible with standard drill press and CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a heavy-duty screw machine length drill bit in the T4HD series, suitable for use with standard straight-shank drill chucks on drill presses, CNC machining centers, and portable drilling equipment accepting cylindrical shanks in the 15\/32 inch size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by machinists or trades professionals using standard drill chuck equipment. Secure the straight-cylindrical shank firmly in the chuck before operation and verify runout before drilling into workpiece material. No coolant-through capability is present on this bit, so external coolant or cutting fluid should be applied when drilling superalloys or hardened materials to manage heat buildup. Inspect the cutting edges for wear or chipping before each use and replace if the split point or flute geometry is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 15\/32 inch (0.4688 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T4HD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.78 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 060430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67906061140274,"sku":"060430","price":25.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b23954809d56912fd84b7a1564ad4e93.jpg?v=1791163852","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-060430-screw-machine-drill-bit-15-32","provider":"Voomi Supply","version":"1.0","type":"link"}
