Built from M42 cobalt high-speed steel and finished with a Titanium Nitride (TiN) coating, this bit delivers extended tool life when cutting through tough materials. It features a 135-degree split point that reduces walking on contact, a web-thinned tapered web for reduced thrust, and a right-hand spiral flute for efficient chip evacuation. Overall length is 5.75 inches with a flute length of 4.3125 inches. The straight cylindrical shank measures 15\/32 inches in diameter, matching the cutting diameter for chuck compatibility.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in fabrication shops, maintenance environments, and field metalworking where stainless steel and hard steel alloys are routinely encountered. The TiN coating and M42 cobalt matrix make it particularly effective in applications where standard high-speed steel bits fail prematurely. Typical users include machinists, pipefitters, ironworkers, and mechanical contractors drilling fastener clearance holes, conduit knockouts, or structural steel connections. It is sold individually and is part of the Chicago-Latrobe Series 2550 heavy-duty line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for heat and wear resistance in hard metals\u003c\/li\u003e\n  \u003cli\u003eTitanium Nitride (TiN) coating extends cutting life and reduces friction\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers required thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web for easier penetration in stainless and alloy steels\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for consistent chip clearance\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J standards for dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling stainless steel and steel workpieces.

Apply cutting fluid or coolant when drilling stainless steel to manage heat buildup and prolong bit life. Secure the workpiece firmly before drilling to prevent movement and bit breakage. Inspect the cutting edges before each use and replace if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15\/32 inches (0.4688 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4375 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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\u003eMaterial\u003c\/strong\u003e: M42 Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\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\u003eStandards\u003c\/strong\u003e: DIN 338, NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2550\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 54073\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51728538960178,"sku":"54073","price":45.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e60e313ed7f74f0e6ab6e15253a8a440.jpg?v=1788692957","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-54073-cobalt-drill-bit-15-32-inch-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
