The bit features a 9\/16 inch cutting diameter paired with a 1\/2 inch Weldon flat shank, allowing it to seat securely in chucks and holders that accept that shank size. The 118-degree standard point angle suits general-purpose drilling applications. An oxide finish provides mild corrosion resistance and reduces friction during cutting. Overall length is 6 inches with a 3-inch flute length, making it a standard jobber-style format suitable for handheld and machine tool use.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in drill presses, milling machines, and compatible power tools equipped with a 1\/2 inch Weldon flat shank holder. The right-hand spiral flute with regular helix evacuates chips efficiently during through-hole and blind-hole drilling. It is suited for production and maintenance work on low and medium tensile strength materials. The 3-flat Weldon shank design prevents slipping under higher feed loads compared to a smooth round shank, which is an advantage in machine tool applications where torque transmission matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16 inch cutting diameter with 1\/2 inch reduced Weldon flat shank for secure tool holding\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling in metal and similar materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides good wear resistance at moderate cutting speeds\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and offers light corrosion protection during storage and use\u003c\/li\u003e\n  \u003cli\u003e3-inch flute length supports chip evacuation in holes up to 3 inches deep\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for standard drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with drill presses, knee mills, and machine tool spindles that accept a 1\/2 inch Weldon flat shank.

Secure the Weldon flat shank fully in the set-screw holder before applying power, ensuring the flat is aligned with the set screw for maximum grip. Power down and lock out the machine spindle before changing or inspecting tooling. Do not exceed the rated cutting speed for high-speed steel in the material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 9\/16 inches (0.5625 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 (3 flats)\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 0.3 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: 77428613\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744132006194,"sku":"77428613","price":62.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/519c6f0fefc7e56276f610b49653fabd.jpg?v=1788854596","url":"https:\/\/voomisupply.com\/products\/hertel-77428613-reduced-shank-drill-bit-9-16-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
