Built to M42 cobalt steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and heat resistance in applications where standard high-speed steel bits wear prematurely. The 135-degree split point starts on contact without center-punching and reduces walking on hard surfaces. At 2 inches overall length with a 1-inch spiral flute, it handles typical jobber-depth holes in stainless steel, alloy steel, and similarly tough workpiece materials. Licensed machinists, maintenance technicians, and fabricators reach for this bit when cutting ferrous metals in production or field repair settings.\u003c\/p\u003e\n\u003cp\u003eThe 54088 is sized at wire gauge number 48, equivalent to 0.0760 inches in decimal. Its straight-cylindrical shank seats in standard drill chucks without modification. The right-hand spiral flute configuration evacuates chips efficiently during through-hole and blind-hole operations in stainless steel and carbon steel. The web-thinned, tapered web geometry reduces thrust requirements, which is especially useful in lighter drill presses or hand-held equipment where operator feed force is limited. This bit is built to DIN 338 and NAS 907 Type J standards, confirming dimensional and performance compliance for aerospace and general industrial use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for heat resistance and edge retention in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends service life and reduces friction against stainless steel and alloy steel\u003c\/li\u003e\n  \u003cli\u003e135-degree split point starts on contact, eliminating the need for a center punch on flat stock\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling thrust for use in lighter equipment\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eBuilt to DIN 338 and NAS 907 Type J dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length replacement drill bit for use in standard drill chucks accepting a 0.0760-inch straight shank.

Secure the shank fully in the chuck jaws before operation. Apply cutting fluid or coolant when drilling stainless steel to manage heat buildup and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or edge rounding is observed to prevent work-hardening of the hole entrance.\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: 48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0760 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\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\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Web-Thinned Tapered\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 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\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\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\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: 54088\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51750148112690,"sku":"54088","price":68.07,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e9448008689255969c529d3a262cb56.jpg?v=1788913831","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-54088-cobalt-jobber-drill-bit-size-48","provider":"Voomi Supply","version":"1.0","type":"link"}
