Built from high-speed steel with an oxide finish, it delivers reliable performance in general-purpose drilling applications. The bit measures 1.125 inches in diameter, carries a 4MT (Morse Taper 4) shank for secure seating in compatible spindles and holders, and features a standard 118-degree point angle suited to a wide range of workpiece materials. The 7.125-inch flute length provides adequate chip clearance on deep-bore passes, while the 12.75-inch overall length accommodates typical drill press and lathe setups.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in machine shop, fabrication, and industrial maintenance environments where large-diameter boring is required. The 4MT taper shank mounts directly into drill press quills, lathe tailstocks, or milling machine spindles equipped with a No. 4 Morse Taper socket. It is suited to ferrous metals, mild steel, cast iron, and similar materials in general-purpose production or maintenance drilling. Machinists, toolroom technicians, and industrial maintenance professionals are the primary installers and operators of this bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.125-inch (1-1\/8 inch) drill diameter for large-bore applications\u003c\/li\u003e\n  \u003cli\u003eNo. 4 Morse Taper (4MT) shank seats firmly in compatible machine spindles\u003c\/li\u003e\n  \u003cli\u003e118-degree point angle for general-purpose drilling across common metals\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction resists heat buildup during extended cuts\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides light corrosion resistance and reduces friction\u003c\/li\u003e\n  \u003cli\u003e7.125-inch flute length supports chip evacuation on deeper passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, lathe tailstocks, and milling machine spindles fitted with a No. 4 Morse Taper (4MT) socket.

Ensure the machine spindle is fully de-energized and at a complete stop before seating or removing the taper shank. Clean both the shank and the spindle socket of chips and oil before inserting to ensure full taper contact and prevent slippage. Use a proper drift and drift slot to remove the bit — never strike the chuck or spindle housing directly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.125 inches (1-1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 4MT (No. 4 Morse Taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.125 inches (7-1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12.75 inches (12-3\/4 inches)\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241639\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: 89323182\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752931819826,"sku":"89323182","price":264.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab7b93440fbc190ee3691c58d7f0de1c.jpg?v=1788931241","url":"https:\/\/voomisupply.com\/products\/hertel-89323182-taper-shank-drill-bit-1-1-8-in-4mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
