The bit features a 1-5\/64 inch cutting diameter paired with a 1\/2 inch straight-cylindrical shank, allowing it to be held in standard 1\/2 inch capacity chucks even at the larger cutting diameter. Constructed from high-speed steel with an oxide finish, the 02387991 carries a 118-degree standard point angle and a right-hand spiral flute configuration suited for general-purpose drilling on drill presses and handheld power tools.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in machine shops, fabrication facilities, and maintenance environments where larger-diameter holes are required without the need for a large-bore chuck. The 6 inch overall length and 3 inch flute length provide adequate chip evacuation and reach for common through-hole and moderate-depth drilling tasks. Trades such as millwrights, pipefitters, and industrial maintenance technicians regularly use reduced shank bits of this type when drilling structural steel, mild steel plate, and similar low-to-medium tensile materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduced 1\/2 inch straight-cylindrical shank accepts standard 1\/2 inch chucks despite the 1-5\/64 inch cutting diameter\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability and heat resistance during general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for reliable self-centering on flat workpiece surfaces\u003c\/li\u003e\n  \u003cli\u003eOxide finish helps reduce friction and surface wear during cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix promotes efficient chip removal\u003c\/li\u003e\n  \u003cli\u003e3 inch maximum drilling depth suitable for a broad range of through-hole and blind-hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose reduced shank drill bit for use with low and medium tensile strength materials, compatible with any drill press or power tool equipped with a 1\/2 inch capacity chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the 1\/2 inch shank firmly in a properly rated chuck before operation. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Use appropriate cutting speeds for the workpiece material and bit diameter to avoid overheating the high-speed steel. Inspect the cutting edges and point for wear or damage before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1-5\/64 inches (1.0781 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: Straight-Cylindrical\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\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 02387991\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753967354162,"sku":"02387991","price":92.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e525504b1c976403377f442c4937afc2.jpg?v=1788942412","url":"https:\/\/voomisupply.com\/products\/hertel-02387991-reduced-shank-drill-bit-1-5-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
