Built from high speed steel with an oxide finish, it provides good wear resistance and heat tolerance during general-purpose machining operations. The bit features a 118-degree standard point angle with a web-thinned tip to reduce thrust and improve chip starting. At 1.0313 inches in diameter with an 11.125-inch overall length, it fits morse taper spindles and drill press quills sized for a 3MT shank. Machinists, tool-and-die techs, and industrial maintenance crews are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling and maintenance machining in shops running drill presses, lathes, milling machines, or radial arm drills equipped with a No. 3 Morse taper socket. The 6.5-inch spiral flute length handles deeper hole applications where a straight shank bit would be impractical. General-purpose right-hand cutting action makes it compatible with conventional spindle rotation. The Series 110 designation places it in CHICAGO-LATROBE's standard general-purpose line, appropriate for a wide range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction with oxide finish for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e118-degree standard point with web thinning to reduce drilling thrust\u003c\/li\u003e\n\u003cli\u003eNo. 3 Morse taper (3MT) shank for direct mount in compatible spindles without a chuck\u003c\/li\u003e\n\u003cli\u003e6.5-inch flute length supports deeper hole drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0015 inches for controlled hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, lathes, milling machines, and radial arm drills equipped with a No. 3 Morse taper (3MT) socket or sleeve.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or maintenance technicians. Power down and lock out the machine before inserting or removing the taper shank. Seat the taper fully into the spindle socket using a firm seating drift or by hand pressure before engaging the draw bolt where applicable. Inspect the taper and socket for nicks or debris that could cause runout before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.0313 inches (1-1\/32 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\u003eOverall Length\u003c\/strong\u003e: 11.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.5 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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 110\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: 1.6634 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: 53166\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748512366898,"sku":"53166","price":143.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a5f631117d7387c1919e6c3acb2fd28_93ed300d-c3d6-41b7-b635-c960ba262f4e.jpg?v=1788894672","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53166-taper-shank-drill-bit-1-0313-in-3mt","provider":"Voomi Supply","version":"1.0","type":"link"}
