Built from high-speed steel with an oxide finish, it delivers reliable performance in ferrous and non-ferrous materials. The bit measures 15\/16 inches in diameter with an overall length of 10.75 inches and seats into the spindle via a No. 3 Morse taper shank. The 118-degree split point geometry reduces walking at drill entry and lowers the thrust required to start the hole. This bit is installed by machinists and tool-and-die professionals using drill presses, lathes, or milling machines equipped with a 3MT spindle socket.\u003c\/p\u003e\u003cp\u003eThis taper shank drill bit is suited for production drilling and general-purpose metalworking in machine shops, manufacturing facilities, and maintenance departments. The No. 3 Morse taper shank provides a secure, self-holding connection in compatible spindle sockets without requiring a separate chuck. The 15\/16-inch diameter is commonly used for bearing bores, clearance holes, and stepped drilling operations. Coolant-through capability is not provided on this bit, making it best suited for conventional flood coolant or dry cutting setups depending on material and feed rate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15\/16 inch diameter with a 0.9375 inch decimal equivalent for precise application matching\u003c\/li\u003e\n\u003cli\u003eNo. 3 Morse taper shank for self-holding fit in 3MT spindle sockets and tailstocks\u003c\/li\u003e\n\u003cli\u003e118-degree split point reduces drill walking and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides heat resistance during metal cutting\u003c\/li\u003e\n\u003cli\u003eOxide finish offers a base level of corrosion resistance and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e10.75 inch overall length accommodates deeper hole depths than standard jobber-length bits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, lathes, and milling machines fitted with a No. 3 Morse taper spindle socket or sleeve.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using a 3MT spindle or tailstock socket; ensure the taper and socket are clean and free of chips before seating the bit. Power down and lock out the machine before inserting or removing the bit. A drift key and soft-faced mallet are the standard tools for ejecting the taper shank from the socket. Do not use this bit in a standard keyed or keyless chuck without an appropriate Morse taper adapter sleeve.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15\/16 inches (0.9375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 3MT (No. 3 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\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241639\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 89323141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744472990002,"sku":"89323141","price":172.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a11f7da6a06804aed9d740448961d6.jpg?v=1788857006","url":"https:\/\/voomisupply.com\/products\/hertel-89323141-taper-shank-drill-bit-15-16-in-3mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
