The bit features a 27\/32-inch cutting diameter paired with a 1\/2-inch Weldon flat shank, allowing it to seat securely in compatible tool holders without slippage. A 118-degree standard point angle provides a reliable, self-centering entry on most common workpiece materials. Overall length is 6 inches with a 3-inch flute length, and an oxide finish helps reduce friction and resist corrosion during cutting operations. This bit is suited for machine shop, fabrication, and maintenance applications where a reduced shank is needed to fit smaller spindle or chuck configurations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in drill presses, milling machines, and CNC machining centers equipped with Weldon flat tool holders accepting a 1\/2-inch shank. It is well matched to low and medium tensile strength workpiece materials including mild steel, aluminum, and similar metals. The right-hand spiral flute design with regular spiral geometry clears chips efficiently during through-hole and blind-hole drilling. Maximum drilling depth corresponds to the 3-inch flute length. No coolant-through capability is present on this bit, so external coolant or cutting fluid should be applied as required by the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/32-inch cutting diameter (0.8438 inches decimal) with 1\/2-inch Weldon flat shank for positive drive and easy tool changes\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for reliable self-centering entry on low and medium tensile strength materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness and wear resistance in general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and provides light corrosion protection during storage and use\u003c\/li\u003e\n  \u003cli\u003e3-inch spiral flute length with regular right-hand flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eThree-flat Weldon shank design prevents bit rotation in the tool holder under cutting load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use reduced shank drill bit compatible with drill presses, milling machines, and machining centers fitted with Weldon flat tool holders accepting a 1\/2-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tool and die professionals familiar with rotating cutting tools. Always power down and lock out the machine before inserting or removing the bit from the tool holder. Verify that the Weldon flat set screw is properly tightened against the shank flat before initiating a cut. Apply appropriate cutting fluid externally, as this bit does not have internal coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 27\/32 inches (0.8438 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\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Low and Medium Tensile Strength Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77428803\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743892406578,"sku":"77428803","price":89.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a07ad10e7382003e0e8cfd6ea05c9db.jpg?v=1788850931","url":"https:\/\/voomisupply.com\/products\/hertel-77428803-reduced-shank-drill-bit-27-32-inch-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
