Built from M42 cobalt high-speed steel and finished with a TiAlN coating, the 45013 delivers extended tool life and heat resistance under demanding production conditions. It features a 135-degree split point for reduced thrust and self-centering starts without a center punch. Overall length is 2.25 inches with a 1.25-inch flute length. The straight-cylindrical shank measures 0.0890 inches in diameter and seats securely in standard drill chucks. This bit is part of the Series 550TA line and is intended for use by machinists, maintenance technicians, and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThe 45013 is sized to wire gauge No. 43, with a decimal diameter of 0.0890 inches, placing it in the 0.0500 to 0.1000 inch diameter range. It is best suited for close-tolerance hole-making in titanium and similarly hard workpiece materials in both shop and field environments. The right-hand spiral flute geometry and web-thinned, tapered web configuration promote efficient chip evacuation and consistent hole quality. This bit is sold individually per package and is compliant with DIN 338 and NAS 907 Type J standards, making it appropriate for aerospace and defense maintenance applications where specification compliance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for high heat resistance and edge retention in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life by reducing friction and oxidation at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces entry thrust and eliminates the need for center-punching\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web improves chip flow and reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, right-hand cut with 2 flutes for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCompliant with DIN 338 and NAS 907 Type J specifications for controlled-application use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or production-use drill bit for applications requiring NAS 907 Type J and DIN 338 compliance.

Secure the shank fully in the chuck jaws before operation to prevent slippage and runout. Use appropriate cutting fluid or coolant for the workpiece material, as this bit does not support through-coolant delivery. Follow applicable shop safety procedures and machine guarding requirements when operating rotary cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0890 inches\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 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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 Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 550TA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 338, NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 45013\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51750147686706,"sku":"45013","price":77.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6c97ed2618771d8a66a82d38b7fd87a.jpg?v=1788913826","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-45013-cobalt-jobber-drill-bit-no-43","provider":"Voomi Supply","version":"1.0","type":"link"}
