It carries a 1-33\/64 inch (1.5156 inch decimal) cutting diameter and mounts via a No. 4 Morse taper shank, which seats directly into compatible taper-socket spindles on drill presses, lathes, and radial arm drills. The 118-degree split or standard point geometry suits general-purpose production and maintenance drilling. An oxide finish provides light corrosion resistance and reduces friction during cutting. Machinists, tool-and-die workers, and industrial maintenance technicians are the typical installers for this size class of bit.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for general-purpose hole making in ferrous and non-ferrous stock where a No. 4 Morse taper drive is available. The 9-3\/8 inch flute length supports deep-hole applications and allows adequate chip evacuation in through-hole operations. The 15 inch overall length accommodates setups where extended reach is required on drill press or lathe spindle configurations. High-speed steel construction holds up under moderate cutting speeds without requiring carbide tooling costs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-33\/64 inch (1.5156 inch) cutting diameter for large-bore hole making\u003c\/li\u003e\n  \u003cli\u003eNo. 4 Morse taper shank seats securely in compatible spindle sockets without a drill chuck\u003c\/li\u003e\n  \u003cli\u003e118-degree point angle for general-purpose drilling in a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability under sustained production use\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and offers light surface protection\u003c\/li\u003e\n  \u003cli\u003e9-3\/8 inch flute length supports chip clearance in deeper cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, lathes, and radial arm drills equipped with a No. 4 Morse taper spindle socket.

Before mounting, clean both the taper shank and the spindle socket thoroughly to ensure full seating contact and prevent runout. Secure the shank fully by hand-pressing it into the socket with a firm push or light mallet tap; never drive with excessive force. To remove, use a drift key through the spindle slot and follow standard machine shop safety practices including de-energizing the machine before any tooling change.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1-33\/64 inches (1.5156 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\u003eOverall Length\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9-3\/8 inches (9.375 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\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: 89323570\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735024468274,"sku":"89323570","price":613.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aed50b50e4e425e15a43a7b899f2c05e.jpg?v=1788769345","url":"https:\/\/voomisupply.com\/products\/hertel-89323570-taper-shank-drill-bit-1-33-64-in-4mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
