Part of the Series 120 lineup, it features a 17\/64 inch (0.2656 inch) diameter, a 118-degree standard point angle, and a web-thinned, tapered web configuration that reduces thrust and improves chip clearance. The right-hand spiral flute geometry promotes consistent chip evacuation during through-hole and deep drilling operations. Constructed from high speed steel with a coated finish for added wear resistance, this bit suits production and maintenance drilling applications where accurate, repeatable hole size is required.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use on ferrous materials including alloy steel, carbon steel, and cast iron in both shop and field environments. Its taper length body, measuring 6.25 inches overall with a 3.875-inch flute length, provides additional reach compared to a jobber-length bit, making it practical for drilling into deeper stock or through thicker structural members. The straight shank diameter of 0.2656 inches (6.75 mm) fits standard drill chucks used on drill presses, hand drills, and CNC machining centers. The coated finish extends service life under moderate-duty cutting conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e17\/64 inch diameter with a tight tolerance of +0.0000 to -0.0010 inches for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003e3.875-inch spiral flute length promotes efficient chip removal in deeper cuts\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability across ferrous material applications\u003c\/li\u003e\n\u003cli\u003eCoated finish improves surface hardness and extends cutting life\u003c\/li\u003e\n\u003cli\u003eStraight shank compatible with standard 3-jaw drill chucks on handheld and stationary equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for general-purpose drilling in alloy steel, carbon steel, and cast iron.

Secure the straight shank fully in the chuck before operation and verify chuck key removal before powering the spindle. Always use appropriate cutting fluid or coolant when drilling ferrous metals to manage heat buildup, even though this bit does not support coolant-through delivery. Wear appropriate PPE including eye protection when operating rotary cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 17\/64 inch (0.2656 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2656 inches (6.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.375 inches (60.32 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight, Non-Threaded\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: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron\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 -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.073 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: 49717\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51731634979122,"sku":"49717","price":22.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/62e15773226bff3852b8cc86c83b84c6.jpg?v=1788733400","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-49717-taper-length-drill-bit-17-64-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
