It features a 25\/32 inch cutting diameter paired with a 1\/2 inch Weldon flat shank, allowing it to seat securely in standard 1\/2 inch chucks and holders without slipping. The 118-degree standard point angle suits general-purpose drilling applications. With a 6 inch overall length and a 3 inch spiral flute length, this bit delivers reliable chip evacuation during through-hole and blind-hole operations. The oxide finish provides a base level of corrosion resistance. Machinists and tool-and-die professionals are the primary installers of this type of bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in drill presses, milling machines, and CNC machining centers where a Weldon flat shank is required for positive drive. It is appropriate for production and maintenance drilling in ferrous and non-ferrous low and medium tensile strength materials such as mild steel, aluminum, and similar workpieces. The right-hand spiral flute geometry with regular spiral type supports standard clockwise-rotation spindles. Single-piece packaging makes it a straightforward replacement or addition to a shop drill index.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25\/32 inch cutting diameter with 0.7812 inch decimal equivalent for precise sizing reference\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch Weldon flat shank with 3 flats for positive, slip-resistant drive in compatible holders\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling into low and medium tensile strength materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness and re-sharpenability\u003c\/li\u003e\n  \u003cli\u003eOxide finish adds surface protection and reduces galling during drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or direct-use reduced shank drill bit for any drill press, milling machine, or machining center equipped with a 1\/2 inch Weldon flat shank holder or collet chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool room personnel. Ensure the spindle is fully stopped and the machine is powered down before seating or removing the bit from its holder. Verify that the Weldon flat is fully aligned with the set screw in the tool holder and that the set screw is tightened to the holder manufacturer's specification before operation. Always confirm that cutting speed and feed rate are appropriate for the workpiece material and bit diameter before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 25\/32 inch (0.7812 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\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: 0.05 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: 77428761\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743925272882,"sku":"77428761","price":82.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/baf61cf9037008dd183f142d54e82f3d.jpg?v=1788851378","url":"https:\/\/voomisupply.com\/products\/hertel-77428761-reduced-shank-drill-bit-25-32-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
