The cutting diameter measures 39\/64 inches (0.6094 inches decimal), while the Weldon shank reduces to 1\/2 inch for broad machine compatibility. Built from high speed steel with a coated finish, this bit handles tough materials encountered in metal fabrication, mechanical assembly, and general trade work. The 118-degree split point promotes accurate starting without a center punch and reduces walking on flat stock.\u003c\/p\u003e\n\u003cp\u003eThis bit belongs to the Series T9FHD line and suits applications in manufacturing, maintenance, and field installation where a standard 1\/2-inch drill press, mag drill, or handheld drill motor is available. The Weldon shank with three flats locks positively into set-screw style chucks and tool holders, preventing slippage under load. Right-hand spiral flutes move chips efficiently out of the hole during drilling. Maximum drilling depth reaches 3 inches, making it appropriate for thick plate and structural steel work as well as general fabrication tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduced shank design allows 39\/64-inch cutting diameter through a standard 1\/2-inch chuck or tool holder\u003c\/li\u003e\n  \u003cli\u003e118-degree split point for self-centering starts and reduced thrust on harder materials\u003c\/li\u003e\n  \u003cli\u003eWeldon shank with three flats prevents rotational slippage in set-screw tool holders\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across steel, cast iron, and general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eCoated finish for improved wear resistance and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2-inch Weldon-style chucks, end mill holders, and set-screw tool holders on drill presses, milling machines, and magnetic base drills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and power is locked out before inserting or removing the bit. Seat the Weldon shank fully into the tool holder and tighten all set screws evenly against the flats before beginning any cut. Use appropriate cutting fluid or coolant for the material being drilled to extend tool life, even though this bit is rated for dry use.\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: 39\/64 inches (0.6094 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\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 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\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\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\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\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\u003eDrill Length Type\u003c\/strong\u003e: Reduced Shank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T9FHD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 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: 094139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRIUMPH TWIST DRILL","offers":[{"title":"Default Title","offer_id":67907216802098,"sku":"094139","price":50.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4585510623cb32210592a33423267ff.jpg?v=1791175725","url":"https:\/\/voomisupply.com\/products\/triumph-twist-drill-094139-reduced-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
