It carries a 43\/64 inch (0.6719 inches) diameter and mounts via a No. 2 Morse Taper (2MT) shank, which seats directly into compatible drill press spindles or lathe tail stocks without a separate chuck. The high speed steel construction with an oxide finish provides adequate heat resistance for general-purpose ferrous and non-ferrous material drilling. The 118-degree standard point angle and right-hand spiral flute geometry suit a broad range of common drilling applications. Installation and operation are handled by machinists and maintenance mechanics.\u003c\/p\u003e\u003cp\u003eThis bit fits standard drilling operations in job shops, industrial maintenance facilities, and production lines where a 2MT taper spindle is available. It is suited for through-hole and blind-hole drilling in mild steel, cast iron, aluminum, and similar materials. The Series 110 designation places it in a general-purpose performance tier. With a 5.375 inch flute length and 9.25 inch overall length, it handles moderate-depth holes without extension tooling. Web-thinned geometry reduces thrust force at the point, which is useful when drilling harder or thicker stock on lower-horsepower machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e43\/64 inch (0.6719 inches) diameter with a tolerance of +0.0000 to -0.0012 inches for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003eNo. 2 Morse Taper (2MT) shank for direct spindle mounting without a drill chuck\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide finish for general-purpose durability\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with right-hand spiral flute and web-thinned tip to reduce entry thrust\u003c\/li\u003e\n\u003cli\u003e5.375 inch flute length supports moderate-depth hole applications\u003c\/li\u003e\n\u003cli\u003eRegular spiral type with no coolant-through requirement, simplifying setup on standard machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, lathes, and milling machines equipped with a No. 2 Morse Taper spindle socket.

Power down and lock out the machine before seating or removing the taper shank. Clean the spindle socket and taper shank with a lint-free cloth before insertion to ensure full contact and prevent slippage. Use a drift and mallet at the spindle knockout slot to safely release the bit after use — never strike the spindle housing directly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 43\/64 inch (0.6719 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 2MT (No. 2 Morse Taper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.375 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\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: 110\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: 53143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51753314812210,"sku":"53143","price":83.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a5f631117d7387c1919e6c3acb2fd28_6c504e84-2112-4a2b-87a5-aba4751f9cae.jpg?v=1788935320","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53143-taper-shank-drill-bit-43-64-in-hss-2mt","provider":"Voomi Supply","version":"1.0","type":"link"}
