Built to M42 cobalt material grade and finished with a titanium nitride (TiN) coating, this bit runs cooler and holds an edge longer than standard high-speed steel alternatives. The 135-degree split point self-centers on contact, reducing walk-out and the need for a center punch. At 4-1\/4 inches overall length with a 2-15\/16-inch flute, it fits standard jobber-length drill chucks and is suited for hand-held drills, drill presses, and CNC applications. Licensed machinists, pipefitters, and HVAC fabricators reach for this bit when cutting sheet metal, structural steel, or stainless pipe flanges.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in metal fabrication, mechanical contracting, and maintenance environments where stainless steel, carbon steel, and similar hard workpiece materials are encountered. The straight-cylindrical shank at 9\/32 inch diameter fits standard three-jaw chucks without adapters. Right-hand spiral flutes evacuate chips efficiently during through-hole drilling. The Series 2550 designation and NAS 907 Type J and DIN 338 standards make it a recognized specification bit for aerospace and industrial procurement. Two-flute geometry keeps cutting forces balanced in both hand and machine-drill setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction delivers heat and wear resistance for hard-metal applications\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends cutting life and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e135-degree split point self-centers and reduces thrust force required to start the hole\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces torque and improves chip clearing in deep holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular-spiral flute geometry provides efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J specifications for precision industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length replacement or specification drill bit for metal-drilling applications requiring NAS 907 Type J or DIN 338 compliance, including stainless steel and carbon steel workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a properly sized three-jaw chuck and confirm the shank is fully seated before operation. Use cutting fluid or coolant when drilling stainless steel to manage heat buildup and extend bit life, even though coolant-through is not supported by this bit internally. Operate at speeds appropriate for cobalt tooling in hard metals — consult the drill speed chart for the workpiece material and bit diameter. Inspect the cutting edges before each use and replace if chipping or dullness is observed to avoid work-hardening the hole entrance in stainless steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9\/32 inch (0.2812 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-15\/16 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inch\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: Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2550\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\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: 54060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51738663387442,"sku":"54060","price":22.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/200bf853e0d2a419566bfde93d66b1d2.jpg?v=1788802470","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-54060-9-32-inch-cobalt-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
