Built from high-speed steel with an oxide finish, it measures 1-5\/16 inches (1.3125 inches) in diameter and features a 118-degree point angle suited for general-purpose drilling in a wide range of ferrous and non-ferrous materials. The 4MT (Morse Taper No. 4) shank seats directly into compatible taper-socket spindles and drill press quills, providing rigid, self-holding alignment without a separate chuck. Machinists and maintenance technicians working with large-format drill presses or lathes with taper bores are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThis bit is intended for general-purpose drilling operations where a large-diameter hole is required in a single pass or as a finish step after piloting. The 8-5\/8-inch flute length provides ample chip clearance during deep-hole drilling, and the 14-1\/4-inch overall length accommodates setups where extended reach is needed. It is appropriate for use in industrial job shops, manufacturing facilities, and maintenance departments running equipment with 4MT-compatible spindles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-5\/16 inch diameter for large-format hole drilling in a single operation\u003c\/li\u003e\n\u003cli\u003e4MT (Morse Taper No. 4) shank for self-holding fit in compatible taper-socket spindles\u003c\/li\u003e\n\u003cli\u003e118-degree point angle suited for general-purpose drilling in steel, cast iron, and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for heat resistance and durability at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eOxide finish provides mild corrosion resistance and reduces surface friction during cutting\u003c\/li\u003e\n\u003cli\u003e8-5\/8-inch flute length supports chip evacuation in deeper drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with drill presses, lathes, and milling machines equipped with a No. 4 Morse Taper (4MT) spindle socket.

Power down and lock out the machine at the main disconnect before seating or removing the bit from the spindle. Insert the taper shank fully into the spindle socket and ensure proper seating by hand before applying power. Use a proper drift and soft mallet to eject the bit from the socket — never apply lateral force to the flutes or shank.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-5\/16 inches (1.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 4MT (Morse Taper No. 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: 8-5\/8 inches (8.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 14-1\/4 inches (14.25 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 89323893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753386475826,"sku":"89323893","price":428.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e700f68b49f663e53626f06c91558bc.jpg?v=1788936118","url":"https:\/\/voomisupply.com\/products\/hertel-89323893-taper-shank-drill-bit-1-5-16-in-4mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
