The bit features a 45\/64 inch (0.7031 inch) cutting diameter paired with a 1\/2 inch Weldon shank, allowing it to seat securely in standard 1\/2 inch chucks and end mill holders without slipping under torque. Built from high speed steel with a coated finish, the 094145 delivers reliable wear resistance across a range of workpiece materials. The split point geometry and right-hand spiral flute promote accurate entry and efficient chip evacuation throughout the cut. Overall length is 6 inches with a maximum drilling depth of 3 inches.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for metalworking, fabrication, and maintenance applications in industrial, commercial, and trade shop environments. The Weldon shank with three flats is the preferred configuration when using end mill holders or set-screw-style tool holders, making this bit a practical choice for drill press and milling machine setups where rotational slippage is a concern. It is sold individually and is appropriate for professionals who need a reliable reduced shank bit for production or repair drilling in steel, aluminum, and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45\/64 inch cutting diameter (0.7031 inch decimal equivalent) on a 1\/2 inch reduced Weldon shank\u003c\/li\u003e\n  \u003cli\u003eSplit point tip for self-centering entry and reduced walking on start\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle suitable for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eThree-flat Weldon shank prevents rotation in set-screw tool holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for standard chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCoated finish on high speed steel body for added surface hardness and wear life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2 inch Weldon-style end mill holders and set-screw chucks on drill presses and milling machines.

Before mounting, ensure the spindle is fully de-energized and the chuck or holder is clean and free of debris. Seat the Weldon shank fully into the holder and tighten set screws against the flats evenly before operation. Do not exceed the recommended maximum drilling depth of 3 inches, and use appropriate cutting fluid for the workpiece material to maintain bit life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 45\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.7031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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 (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank\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\u003eSeries\u003c\/strong\u003e: T9FHD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 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: 094145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67909707071794,"sku":"094145","price":57.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43674a207f1dc19e94e7fb5df95686a5.jpg?v=1791190151","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-094145-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
