Built from M42 cobalt high-speed steel with a black oxide finish, it delivers superior heat and wear resistance compared to standard HSS bits. The 135-degree split point reduces walking and allows self-centering starts without a center punch. At 17\/64 inch in diameter with a 3-7\/8 inch flute length and 6-1\/4 inch overall length, this bit suits applications where a longer reach is needed beyond a jobber-length tool. Spiral flutes with web thinning promote chip evacuation and reduce thrust. Licensed trades and industrial machinists turn to this bit for demanding production environments.\u003c\/p\u003e\n\u003cp\u003eThe 44817 is rated for use in cast iron, high-tensile steel, Inconel, manganese steel, and titanium  -  materials that defeat standard carbon or uncoated HSS tooling. The taper length body gives added reach in deep-hole setups, blind bores, and fixture drilling where a jobber bit falls short. The straight cylindrical shank seats in standard drill chucks and collet holders without modification, making it compatible with bench drills, drill presses, and CNC machining centers used in fabrication, maintenance, and aerospace MRO workflows.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for extended tool life in hard and high-temperature alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering starts and reduced thrust load\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish improves lubricity and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web promotes chip clearance and lowers drilling torque\u003c\/li\u003e\n  \u003cli\u003eTaper length body provides extra reach over standard jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix suits a wide range of material feeds and speeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron, high-tensile steel, Inconel, manganese steel, and titanium.

Use cutting fluid or coolant appropriate for the workpiece material  -  cobalt tooling tolerates dry cutting in many ferrous applications, but lubrication extends tool life in stainless and nickel alloys. Secure the workpiece firmly to prevent movement during drilling. Inspect the cutting edges before each use; cobalt bits are brittle under lateral load and should not be used in applications with significant side pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 17\/64 inch (0.2656 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\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2656 inch (6.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.3750 inches (60.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular Helix)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter 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\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, High-Tensile Steel, Inconel, Manganese Steel, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 44817\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51743328731442,"sku":"44817","price":33.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c3f8d983f5765920e44832087e405cc_d7dfd131-465e-40d6-99ae-185805fda7c5.jpg?v=1788845702","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44817-taper-length-cobalt-drill-bit-17-64","provider":"Voomi Supply","version":"1.0","type":"link"}
