It carries a 4MT (Morse Taper 4) shank, making it compatible with machine spindles and drill press quills that accept this taper designation. The cutting end measures 1.2656 inches (1-17\/64 inches) in diameter with a 118-degree standard point angle and web-thinned geometry to reduce thrust and improve chip ejection at entry. Constructed from high speed steel with an oxide finish, this bit is built for general-purpose production and toolroom applications where consistent, repeatable hole quality is required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for machine shop, maintenance, and industrial fabrication environments where large-diameter through-holes or blind holes are needed. The Series 209 design follows ANSI standards and is typically chucked directly into a drill press, milling machine, or lathe tailstock equipped with a 4MT socket. The spiral flute configuration and right-hand cutting direction are standard for conventional drilling setups. The bit is not configured for coolant-through operation, so flood coolant or cutting oil applied externally is the appropriate lubrication method for extended runs in ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.2656 inch (1-17\/64 inch) cutting diameter for large-format hole work\u003c\/li\u003e\n  \u003cli\u003e4MT Morse Taper shank seats directly in compatible machine spindles without a chuck\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip reduces entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide finish for general-purpose durability\u003c\/li\u003e\n  \u003cli\u003e8.5 inch spiral flute length supports deeper cuts with adequate chip clearance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, regular spiral, ANSI-compliant Series 209 geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use taper shank drill bit for machine spindles and drill press quills accepting a 4MT (Morse Taper 4) shank designation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians familiar with Morse taper tooling. Before seating the bit, ensure the machine spindle socket is clean and free of chips or burrs that could prevent full taper engagement. Power down and lock out the machine before inserting or removing the bit. Use a drift and knockout bar to remove the taper shank — never strike the bit directly. Apply cutting oil or flood coolant externally during operation, as this bit does not support internal coolant delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.2656 inches (1-17\/64 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\u003eOverall Length\u003c\/strong\u003e: 14.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.5 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 209\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5999483\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699917291826,"sku":"5999483","price":287.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91f3c7609b9c9ca5a8425dc07c240c2d_102ac32e-016c-48a8-81af-7bcef7f8adcb.jpg?v=1788383348","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999483-taper-shank-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
