Built to Series 2550 standards, this bit measures 1\/8 inch in diameter with a 2-3\/4 inch overall length and a 1-5\/8 inch flute length. The 135-degree split point reduces walking and lowers thrust required at entry, making it well suited for production and maintenance drilling. A titanium nitride (TiN) coating increases surface hardness and extends tool life in abrasive materials. The M42 cobalt steel construction provides heat resistance during high-speed or interrupted cuts. This bit is installed by machinists, pipefitters, HVAC technicians, and maintenance trades needing reliable small-diameter drilling in hard stock.\u003c\/p\u003e\n\u003cp\u003eThe CHICAGO-LATROBE 54050 is intended for drilling stainless steel and steel as its primary workpiece materials, making it a go-to choice in mechanical, HVAC, and plumbing service environments where stainless fasteners, fittings, and brackets are common. The right-hand spiral flute with web-thinned, tapered web geometry promotes efficient chip evacuation in deep or blind holes. It is sold individually and fits standard 3-jaw drill chucks that accept a 1\/8 inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for heat resistance and durability in hard materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and minimizes entry thrust\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating extends wear life in abrasive and high-temperature applications\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web improves chip evacuation and reduces torque requirements\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, right-hand cut with 2-flute geometry for clean, efficient drilling\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any standard drill chuck accepting a 1\/8 inch straight-cylindrical shank.

Secure the workpiece before drilling to prevent rotation or movement. Use cutting fluid when drilling stainless steel to manage heat buildup and extend bit life. Inspect the cutting edge before each use and replace bits showing chipping or excessive wear to maintain hole quality and prevent breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1250 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\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\u003eMaterial\u003c\/strong\u003e: Cobalt (M42 grade)\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\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: 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\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: 54050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51738678362418,"sku":"54050","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5af80ac880eed4beede4712b828a0e3.jpg?v=1788802715","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-54050-cobalt-jobber-drill-bit-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
