It features a 5\/16-inch diameter cutting edge ground to a 118-degree point angle, which is the standard geometry for drilling into a wide range of workpiece materials. The No. 1 Morse Taper (1MT) shank seats directly into compatible taper-socket spindles on drill presses and lathes, eliminating the need for a separate chuck. The high-speed steel (HSS) construction with an oxide finish provides moderate wear resistance and corrosion protection for everyday shop and field use.\u003c\/p\u003e\u003cp\u003eThis bit is suited for general-purpose drilling operations in machine shop, maintenance, and light fabrication environments. The 1MT shank makes it compatible with drill presses, turret lathes, and milling machines equipped with a No. 1 Morse Taper socket. It is commonly used by machinists, maintenance mechanics, and toolroom technicians who require a direct-spindle-mount bit for repetitive or precision drilling tasks where a keyed chuck would introduce runout or add unnecessary length to the setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-inch (0.3125 inches) diameter for standard fractional hole sizes\u003c\/li\u003e\n\u003cli\u003eNo. 1 Morse Taper (1MT) shank for direct spindle mounting without a chuck\u003c\/li\u003e\n\u003cli\u003e118-degree point angle — standard geometry for general-purpose drilling in steel, aluminum, and wood\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eOxide finish provides basic corrosion and wear resistance\u003c\/li\u003e\n\u003cli\u003e3-1\/8-inch flute length supports adequate chip evacuation in moderate-depth holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for any drill press, lathe, or milling machine spindle that accepts a No. 1 Morse Taper (1MT) socket.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a No. 1 Morse Taper socket or sleeve; ensure the taper and socket are clean and free of chips or burrs before seating the shank. Drive the bit firmly into the socket by hand or with a soft mallet — never use a steel hammer directly on the shank. To remove, use the appropriate drift key through the spindle drift slot. Always secure the workpiece and verify spindle speed is appropriate for the material and drill diameter before operating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 1MT (No. 1 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: 3-1\/8 inches (3.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6-3\/8 inches (6.3750 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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 89323380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733088207154,"sku":"89323380","price":49.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd3ea2acc0f6057c679af561f9393efe.jpg?v=1788751226","url":"https:\/\/voomisupply.com\/products\/hertel-89323380-taper-shank-drill-bit-5-16-in-1mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
