Part of the Series 520 lineup, this bit measures 25\/64 inch (0.3906 inch) in diameter and carries a 135-degree split-point tip that enables self-centering entry without a center punch. The black oxide finish reduces friction and helps with chip evacuation. At 7 inches overall length with a 4-3\/8 inch spiral flute, it delivers the extended reach that taper length geometry is known for. The straight cylindrical shank and right-hand cut make it compatible with standard drill chucks. Material grade M42 cobalt provides heat resistance and edge retention for demanding production work.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for metalworking applications in both shop and field environments. It is designed for cutting cast iron, high-tensile steel, Inconel, manganese steel, and titanium  -  materials that typically defeat standard high-speed steel bits. The self-centering split point and web-thinned tip reduce thrust requirements, making it practical for hand-held drilling as well as drill press and CNC setups. Machinists, maintenance technicians, and metalworking tradespeople are the primary users of this bit type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point with web thinning for self-centering entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eM42 cobalt steel construction withstands heat buildup in hard and exotic alloys\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating reduces friction and provides basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eTaper length geometry at 7 inches OAL provides extended reach over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with tapered web configuration improves chip clearing\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in cast iron, high-tensile steel, Inconel, manganese steel, and titanium.

Before mounting, confirm the chuck or collet is clear of debris and the workpiece is secure. Use appropriate cutting fluid for hard alloys such as Inconel or titanium to extend tool life. Inspect the cutting edges before use  -  cobalt bits are brittle under side loads and should not be used as a lever or pry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 520\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 25\/64 inch (0.3906 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25\/64 inch (9.92 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.625 inches (66.67 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt, Grade M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, High-Tensile Steel, Inconel, Manganese Steel, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreaded Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2008 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: 44825\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51739821506866,"sku":"44825","price":53.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c3f8d983f5765920e44832087e405cc_b0695491-5622-4972-a927-1535cbda11b0.jpg?v=1788819272","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44825-taper-length-drill-bit-25-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
