It measures 1-11\/32 inches (1.3438 inches decimal) in diameter and carries a 4MT (Morse Taper 4) shank for secure seating in compatible drill press spindles and lathes. The 118-degree point angle suits general-purpose drilling across a wide range of workpiece materials. Finished with a black oxide coating for basic corrosion resistance, this bit is manufactured from high-speed steel (HSS) and is intended for machinists, tool-and-die tradespeople, and industrial maintenance technicians who require a reliable, large-diameter boring solution.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for use in vertical drill presses, radial arm drills, and engine lathes equipped with a 4 Morse Taper spindle socket. It handles general-purpose production and maintenance drilling tasks in shop and industrial environments where a 1-11\/32-inch hole diameter is required. The 8-3\/4-inch flute length accommodates deeper bore passes without frequent retraction, and the 14-3\/8-inch overall length provides adequate reach for most production setups. Typical users include machine shop technicians, millwrights, and industrial maintenance mechanics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-11\/32 inch (1.3438 inch decimal) drill diameter for large-bore applications\u003c\/li\u003e\n  \u003cli\u003e4MT Morse Taper shank for self-holding fit in compatible spindles\u003c\/li\u003e\n  \u003cli\u003e118-degree point angle optimized for general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides hardness and wear resistance at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers baseline corrosion and chip-weld resistance\u003c\/li\u003e\n  \u003cli\u003e8-3\/4-inch flute length supports deeper bore passes with efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill press spindles, radial arm drills, and engine lathes fitted with a 4 Morse Taper (4MT) socket.

Power down and lock out the machine before seating or removing the bit from the spindle. Use a proper drift key and drift slot to eject the taper shank — never hammer the bit directly. Ensure the taper surfaces are clean and free of chips or oil film before seating to prevent slippage under load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-11\/32 inches (1.3438 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 4MT (Morse Taper 4)\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: 8-3\/4 inches (8.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 14-3\/8 inches (14.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black 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: 89323877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730953503026,"sku":"89323877","price":297.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3a933811c6ab62852858cabfbfe8ef6.jpg?v=1788725221","url":"https:\/\/voomisupply.com\/products\/hertel-89323877-taper-shank-drill-bit-1-11-32-in-4mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
