Built to Series 2550 standards and coated with titanium nitride (TiN), it delivers extended tool life and reduced friction in demanding applications. The bit features a 135-degree split point for fast, self-centering starts with minimal walking, and a web-thinned, tapered web configuration for reduced thrust requirements. At 0.1910 inches in diameter (wire size 11) with an overall length of 3.5 inches and a flute length of 2.3125 inches, this is a compact, precision-ground bit built for daily production use.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for drilling stainless steel and general-purpose steel in trade and industrial environments. The M42 cobalt high-speed steel construction handles the heat and abrasion generated when cutting hard or work-hardening alloys. Right-hand cut, two-flute spiral design with a straight-cylindrical shank suits standard three-jaw chucks and drill press setups. Typical applications include fabrication shops, mechanical contractors, pipefitters, and maintenance technicians working with stainless fastener holes, structural steel, or high-strength alloys. Meets DIN 338 and NAS 907 Type J standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for heat resistance in stainless steel and hard alloys\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends cutting life\u003c\/li\u003e\n  \u003cli\u003e135-degree split point starts on contact without a center punch\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web lowers thrust force and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute regular spiral for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J specifications for dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber-length drill bit compatible with standard three-jaw chucks and drill presses accepting a 0.1910-inch straight-cylindrical shank.

Secure the workpiece and ensure the chuck is fully tightened before operation. Use appropriate cutting fluid or coolant when drilling stainless steel to manage heat and extend tool life. Inspect the bit for chipping or wear before each use and replace if the cutting edge is compromised.\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: 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1910 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42 Cobalt HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1910 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 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\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: 54021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51729152803122,"sku":"54021","price":17.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a1d5a2dc100c41f1b19eca2c5ff7402.jpg?v=1788700973","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-54021-cobalt-jobber-drill-bit-wire-11","provider":"Voomi Supply","version":"1.0","type":"link"}
