It features a 1-5\/64 inch (1.0781 inch decimal) cutting diameter with a reduced 1\/2 inch Weldon flat shank, allowing it to seat securely in standard chucks and tool holders without requiring a full-diameter collet. Built from high-speed steel with an oxide finish, this bit offers solid wear resistance for production and maintenance drilling applications. It is right-hand cut with a standard 118-degree point angle and spiral flutes for efficient chip evacuation.\u003c\/p\u003e\u003cp\u003eThis drill bit suits metalworking applications in fabrication shops, maintenance facilities, and general industrial settings. The reduced shank design makes it compatible with 1\/2 inch capacity drill chucks and tool holders, even though the cutting diameter exceeds that size. The 3-inch flute length supports drilling to a maximum depth of 3 inches, making it appropriate for through-holes and moderate-depth blind holes in plate stock, structural steel, and similar workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-5\/64 inch cutting diameter (1.0781 inch decimal) with a reduced 1\/2 inch shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability in low and medium tensile strength materials\u003c\/li\u003e\n\u003cli\u003eOxide finish provides basic corrosion resistance and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003eStandard 118-degree point angle for general-purpose drilling in metal\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank with 3 flats prevents shank slippage in set-screw tool holders\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flutes promote efficient chip removal during through-hole and blind-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1\/2 inch capacity drill chucks and Weldon-style tool holders.

Secure the shank fully in the holder and tighten all set screws against the flats before use. Power down and lock out the machine before changing bits. Coolant is not required for this bit but can be used to extend tool life in high-cycle applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1-5\/64 inches (1.0781 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\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\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Low and Medium Tensile Strength Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Required\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77428944\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":52093726949682,"sku":"77428944","price":94.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d61d170b64bb611dd6c7e0b54dfbdd5.jpg?v=1790064812","url":"https:\/\/voomisupply.com\/products\/hertel-77428944-reduced-shank-drill-bit-1-5-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
