Built to Series 550 standards, it carries an M42 cobalt steel construction with a gold oxide coating that reduces friction and extends cutting life. The 135-degree split point starts on contact without walking, eliminating the need for a center punch on most surfaces. At 4 inches overall length with a 2.75-inch flute length, this bit fits standard jobber-length drill chucks and is sized for right-hand, two-flute spiral cutting action.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for metalworking professionals, maintenance machinists, and fabricators working in aerospace, industrial, and heavy-duty manufacturing environments. The 0.246-inch diameter and straight-cylindrical shank make it compatible with standard keyed or keyless drill chucks in benchtop drill presses, magnetic drills, and hand drills. The tapered web and web-thinned geometry reduce thrust force, making it particularly effective when drilling titanium and high-nickel alloys where heat buildup is a concern. It conforms to DIN 338 and NAS 907 Type J specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for hardness and heat resistance in demanding materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point for self-centering starts and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating minimizes friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web geometry reduces cutting resistance in hard alloys\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular spiral type for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard jobber-length drill applications requiring a 0.246-inch diameter bit with a straight-cylindrical shank. Primary workpiece material is titanium; also suitable for high-strength alloys and hard metals consistent with M42 cobalt tooling.

Always wear appropriate eye protection and secure the workpiece before drilling. When drilling titanium or hard alloys, use a cutting fluid or lubricant to manage heat and extend bit life. Inspect the cutting edges before each use and replace if chipping or dullness is observed to avoid workpiece damage or bit failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.246 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.246 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 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\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\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\u003eCoating\u003c\/strong\u003e: Gold Oxide\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: Titanium\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 550\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\u003eWeight\u003c\/strong\u003e: 0.042 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: 46774\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51728618619186,"sku":"46774","price":15.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e18f3a73fcc1e869d3fccf79cdc8be4_f6ee95b6-2fda-4234-a66b-04b54ebe0f94.jpg?v=1788694038","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-46774-cobalt-jobber-drill-bit-0-246-in","provider":"Voomi Supply","version":"1.0","type":"link"}
