The bit features a 5\/8 inch cutting diameter with a 1\/2 inch Weldon flat shank, allowing it to seat securely in milling chucks and Weldon-style holders without slipping under torque. The 118-degree standard point angle suits general-purpose drilling applications. An oxide finish provides light corrosion resistance and reduces friction during cutting. This bit is a standard choice for machinists, maintenance technicians, and fabricators working on production or repair operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in drill presses, milling machines, and magnetic drill setups where a Weldon flat shank is required for positive drive engagement. The reduced shank design allows a 5\/8 inch diameter bit to be held in a 1\/2 inch capacity chuck or holder, expanding the range of machines it can be used with. It is appropriate for shop floor, maintenance, and light fabrication environments working primarily with low and medium tensile strength metals and similar machinable materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8 inch cutting diameter with a reduced 1\/2 inch Weldon flat shank for positive drive in standard holders\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\u003e3-inch flute length and 6-inch overall length for adequate reach in typical workpieces\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability in general metalworking applications\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and offers light protection against corrosion\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular spiral type for standard chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Weldon-style drill chucks, milling machine holders, and magnetic drill units that accept a 1\/2 inch Weldon flat shank.

Ensure the machine is fully powered down and the spindle is stationary before seating or removing the bit from its holder. Confirm the Weldon flat is properly engaged with the set screw in the holder before operation to prevent bit pull-out under load. Do not exceed the recommended drilling depth of 3 inches for this bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\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: 0.3 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: 77428662\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743783878962,"sku":"77428662","price":68.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b957d826f4f08039ca27b04489c93095.jpg?v=1788849648","url":"https:\/\/voomisupply.com\/products\/hertel-77428662-reduced-shank-drill-bit-5-8-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
