Built to wire gauge size 48 with a decimal diameter of 0.0760 inches, it features a 135-degree split point that reduces walking and allows immediate cutting contact without a center punch. The TiAlN (Titanium Aluminum Nitride) coating adds heat and wear resistance, making it well-suited for sustained production use. At 2 inches overall length with a 1-inch spiral flute, the 45018 is sized for close-tolerance work in tight-clearance applications. The M42 cobalt steel construction provides hardness retention at elevated cutting temperatures.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for drilling titanium as its primary workpiece material, which is consistent with the NAS 907 Type J and DIN 338 standards it meets. It is well-matched for aerospace, industrial maintenance, and precision fabrication environments where titanium and other high-strength alloys are regularly machined. The right-hand spiral flute and web-thinned, tapered web geometry promote chip evacuation and reduce thrust force. It is sold individually per package with a minimum order quantity of 12 units, making it practical for shop stocking or field service kits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 48 diameter: 0.0760 inches with a tolerance of -0.0005 to 0.0000 inches for close-tolerance drilling\u003c\/li\u003e\n  \u003cli\u003eM42 cobalt steel construction retains hardness under high cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating increases surface hardness and heat resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web-thinned, tapered web reduces thrust and eliminates walking\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, right-hand cut with 2-flute design promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J standards for use in regulated manufacturing environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production drill bit for applications involving titanium and other high-strength alloys per NAS 907 Type J specification, in Series 550TA. No coolant-through capability; intended for use with standard drill chucks accepting a 0.0760-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is intended for use by machinists, tool-and-die professionals, aerospace fabricators, and industrial maintenance technicians. Secure the straight-cylindrical shank firmly in a compatible drill chuck before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Do not exceed the recommended feed rate for small-diameter cobalt bits, as excessive force can cause breakage. When drilling titanium, use appropriate cutting fluid to manage heat even though this bit does not have coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0760 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt, M42 Grade\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 Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0760 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 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\u003eFinish\/Coating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: 550TA\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: 45018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727455650098,"sku":"45018","price":78.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcf203fd272fdfb17bffa93c0bff5870.jpg?v=1788678117","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-45018-cobalt-jobber-drill-bit-wire-48","provider":"Voomi Supply","version":"1.0","type":"link"}
