Built from high speed steel (HSS) with an oxide finish, it delivers consistent performance in general-purpose machining applications. The bit measures 1.25 inches in diameter with an overall length of 13.5 inches and a flute length of 7.875 inches. A 118-degree standard point geometry provides a reliable, self-centering entry, while the web-thinned construction reduces thrust load and improves chip clearance. Machinists and tool-room professionals are the primary installers of this bit in drill press and lathe setups.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for general-purpose metal drilling in both production shop and maintenance environments. The 4MT (Morse Taper 4) shank seats directly into matching taper-socket spindles on drill presses, lathes, and radial arm drills without requiring a chuck. Its right-hand spiral flute design efficiently evacuates chips during through-hole and deep-hole drilling operations. The Series 110 designation places it within CHICAGO-LATROBE's standard HSS taper shank line, commonly used in industrial and trade shop settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.25-inch diameter with a diameter tolerance of +0.0000 to -0.0015 inches for consistent, accurate hole sizing\u003c\/li\u003e\n\u003cli\u003e4MT (Morse Taper 4) shank for direct, no-chuck mounting in compatible spindles\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned geometry for reduced thrust and easier starting\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across a wide range of general-purpose drilling tasks\u003c\/li\u003e\n\u003cli\u003eOxide finish provides a base level of lubricity and corrosion resistance during storage and use\u003c\/li\u003e\n\u003cli\u003eRight-hand regular spiral flute, 7.875 inches long, for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to seat in any machine spindle or sleeve with a No. 4 Morse Taper socket, including standard drill presses, lathes, and radial arm drills equipped with 4MT tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or qualified tool-room technicians. Before mounting, confirm the spindle socket and taper shank are clean and free of chips or burrs to ensure full taper contact. Insert the shank with the tang aligned to the drift slot and seat firmly with a mallet if required. Always power down and lock out the machine before inserting or removing taper shank tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.25 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: 13.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.875 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, 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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0015 inches\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: 110\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHICAGO-LATROBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 53180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51731056132402,"sku":"53180","price":216.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a5f631117d7387c1919e6c3acb2fd28_0f96f8b9-6c07-4ef3-a7c5-26d481318457.jpg?v=1788726333","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53180-taper-shank-drill-bit-1-25in-4mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
