The bit features a 19\/32 inch cutting diameter with a 1\/2 inch Weldon flat shank, allowing it to seat securely in compatible chucks and reduce slippage under load. The 118-degree standard point angle is suited for general-purpose drilling into low and medium tensile strength materials. With a 6 inch overall length and a 3 inch flute length, this bit is appropriate for moderate-depth hole work. It is a right-hand cut design with a regular spiral flute. Machinists, maintenance technicians, and metalworking professionals install this bit in standard drill presses, milling machines, and compatible handheld equipment.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in metalworking and general fabrication environments where a reduced shank design is needed to fit a 1\/2 inch chuck while maintaining a larger cutting diameter. Primary workpiece materials include low and medium tensile strength metals such as mild steel, aluminum, and similar materials. The Weldon flat shank with three flats provides positive drive engagement, making it well suited for machine tool applications where torque transfer and bit retention are critical. It is sold individually and is appropriate for both production shop use and maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e19\/32 inch cutting diameter with a reduced 1\/2 inch Weldon flat shank for compatibility with standard chucks\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of metalworking applications\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\u003eOxide finish for basic surface protection and heat resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003e3-flat Weldon shank design resists rotational slippage under cutting load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, milling machines, and other machine tools equipped with a 1\/2 inch chuck or collet.

Ensure the machine is fully powered down and locked out before changing bits. Confirm the Weldon flat is properly aligned with the set screw in the chuck or tool holder before applying torque. Do not exceed the rated drilling depth of 3 inches for a single pass without clearing chips from the flutes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 19\/32 inches (0.5938 inches 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\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\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 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: 77428639\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739332444466,"sku":"77428639","price":66.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/743bcfaebb2db8d128218999ada6a462.jpg?v=1788813243","url":"https:\/\/voomisupply.com\/products\/hertel-77428639-reduced-shank-drill-bit-19-32-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
