It features a 43\/64 inch (0.6719 inch decimal) cutting diameter paired with a 1\/2 inch Weldon flat shank, allowing it to seat securely in Weldon-style end mill holders and reduce slippage under torque. The 118-degree standard point angle suits general-purpose drilling in mild steel, aluminum, and similar materials. An oxide finish provides basic lubricity and surface protection. This bit is a standard tool for machinists, millwrights, and maintenance technicians working on drill presses, milling machines, or CNC equipment.\u003c\/p\u003e\n\u003cp\u003eThis drill bit fits applications requiring a large-diameter hole with a reduced 1\/2 inch shank for compatibility with common toolholders. It is well suited for job shop work, light manufacturing, and facility maintenance where low to medium tensile strength materials such as mild steel, aluminum, and soft alloys are the primary workpiece. The right-hand spiral flute design clears chips efficiently during through-hole and blind-hole drilling operations. With a 3 inch flute length and 6 inch overall length, it handles moderate drilling depths without excessive extension beyond the toolholder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e43\/64 inch (0.6719 inch decimal) cutting diameter with a reduced 1\/2 inch Weldon flat shank\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling in low and medium tensile strength materials\u003c\/li\u003e\n  \u003cli\u003eThree-flat Weldon shank design prevents rotation in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide finish for surface protection and basic lubricity\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute geometry for reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003e3 inch flute length supports drilling depths up to 3 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Weldon-style toolholders accepting a 1\/2 inch shank diameter, suitable for drill presses, manual mills, and CNC machines configured for reduced shank drill bits in low to medium tensile strength materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or maintenance technicians. Ensure the machine spindle is fully powered down and the toolholder is clean and free of debris before seating the shank. Torque the Weldon set screw against the flat per the toolholder specification to prevent shank slippage during operation. This bit is not rated for coolant-through use; external coolant or cutting fluid should be applied as appropriate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 43\/64 inch (0.6719 inch decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\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\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\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\u003eCoolant\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77428696\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740248178994,"sku":"77428696","price":75.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48ef4d698248e4ce16967d12addb0490.jpg?v=1788823746","url":"https:\/\/voomisupply.com\/products\/hertel-77428696-reduced-shank-drill-bit-43-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
