Built from high speed steel with an oxide finish, this bit measures 1.1875 inches in diameter and carries a 4MT (Morse taper 4) shank for secure seating in compatible drill press spindles and lathes. The 118-degree standard point angle and spiral flute geometry suit general-purpose drilling in a wide range of shop and industrial applications. A web-thinned point reduces thrust requirements at entry. Overall length is 13 inches with a flute length of 7.375 inches.\u003c\/p\u003e\u003cp\u003eThis bit is intended for stationary machine tool setups, including drill presses, lathes, and milling machines equipped with a No. 4 Morse taper socket. Typical applications include production drilling, maintenance shops, and toolroom work where consistent hole diameter tolerances are critical. The right-hand cutting direction and regular spiral type make it suitable for through-hole and blind-hole drilling in ferrous and non-ferrous metals. General-purpose performance classification means it fits a broad range of shop drilling tasks without specialized setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.1875-inch diameter with a tight tolerance of +0.0000 to -0.0015 inches for accurate hole sizing\u003c\/li\u003e\n\u003cli\u003e4MT (Morse Taper 4) shank for positive, self-holding fit in compatible spindles\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across general-purpose metal drilling\u003c\/li\u003e\n\u003cli\u003eOxide finish helps reduce friction and provides basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eWeb-thinned standard point reduces entry thrust and improves chip clearance\u003c\/li\u003e\n\u003cli\u003eSpiral flute, right-hand cutting direction for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, lathes, and machine tool spindles fitted with a No. 4 Morse taper (4MT) socket.

Power down and lock out the machine before seating or removing the taper shank. Clean both the spindle taper bore and the bit shank of chips, oil, and debris before seating to ensure full contact and prevent fretting. Use a proper drift and drift slot to remove the bit — 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: 1.1875 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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.375 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, 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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 2.88 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: 53176\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51744957301042,"sku":"53176","price":192.2,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a5f631117d7387c1919e6c3acb2fd28_bae9d14f-0ef3-4afa-af3e-f6bf0f074d18.jpg?v=1788862694","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-53176-taper-shank-drill-bit-1-1875-in-4mt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
