Built from high speed steel (HSS) with a coated finish, this 0.5 inch diameter bit features a 135-degree split point that reduces walking and requires no center punch on most materials. The spiral flute design promotes chip evacuation, and the web-thinned, tapered web construction reduces cutting resistance. At 3.75 inches overall length with a 2.25 inch flute length, this stub-length bit provides increased rigidity compared to jobber-length alternatives. Licensed HVAC techs, machinists, and maintenance professionals working with tough ferrous materials will find this bit suited to demanding production drilling tasks.\u003c\/p\u003e\u003cp\u003eThe 060432 is engineered for drilling precipitation-hardened steels and superalloys, making it appropriate for aerospace, industrial maintenance, and fabrication applications where standard drill bits deflect or wear prematurely. The screw machine length keeps the bit short and stiff, which is especially useful in drill presses, CNC turret machines, and hand-held drill motors in tight quarters. The straight-cylindrical shank fits standard three-jaw drill chucks without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5 inch diameter with 135-degree split point for fast, accurate starts on hard materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life in ferrous metals\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 3.75 inches overall for maximum rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces thrust and cutting resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute promotes efficient chip clearing during deep passes\u003c\/li\u003e\n\u003cli\u003eSeries T4HD heavy-duty grade rated for PH steel and superalloy workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for any application requiring a 0.5 inch diameter, screw machine length, straight-shank HSS drill bit.

Secure the straight-cylindrical shank fully into the chuck jaws before beginning any operation. Always power down and lock out equipment before changing bits. Use appropriate cutting fluid or coolant when drilling PH steels and superalloys to manage heat buildup and extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.25 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\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\u003eTool Performance Grade\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\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\u003eWeight\u003c\/strong\u003e: 0.91 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: 060432\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67906252276018,"sku":"060432","price":26.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14e0e5da643afebec39be3b44ff3b3e6.jpg?v=1791166573","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-060432-screw-machine-drill-bit-0-5in","provider":"Voomi Supply","version":"1.0","type":"link"}
