Built to Series 550 standards and conforming to DIN 338 and NAS 907 Type J specifications, this bit is manufactured from M42 cobalt high-speed steel and finished with a gold oxide coating to reduce friction and extend tool life in demanding materials. The straight-cylindrical shank and spiral flute geometry make it compatible with standard drill chucks. It is sized for precision small-diameter work and is classified as a heavy-duty, high-performance cutting tool.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for drilling titanium and similarly hard or abrasive metals where standard high-speed steel tooling fails prematurely. The web-thinned, tapered-web point reduces thrust and improves chip evacuation in tight geometries. Typical applications include aerospace component fabrication, precision machining, and any production environment requiring consistent dimensional accuracy in sub-1\/8-inch hole diameters. It is sold individually but requires a minimum order quantity of 12 units per purchase. Machinists, tool-and-die professionals, and aerospace maintenance technicians are the primary users.\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 titanium and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree point angle reduces walking and entry force on hard materials\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating lowers friction and extends cutting life\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web improves chip clearance and reduces thrust\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 and NAS 907 Type J dimensional standards\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length replacement or production bit for applications requiring wire gauge size 76 (0.0200 inches) hole diameters, particularly in titanium and other high-strength workpiece materials per NAS 907 Type J specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit should be installed in a drill press, CNC machine, or precision hand drill with a chuck capable of gripping a 0.0200-inch straight-cylindrical shank securely. Use appropriate cutting fluid or lubricant when drilling titanium to manage heat buildup. Inspect the cutting edges before each use; at this diameter, the bit is susceptible to breakage if run at incorrect speeds or feeds. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for cobalt tooling in the target workpiece material.\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: 76\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0200 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\u003eOverall Length\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.6875 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 Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eFinish\/Coating\u003c\/strong\u003e: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eStandards\u003c\/strong\u003e: DIN 338, NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 550\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 46746\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51732354662706,"sku":"46746","price":85.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e18f3a73fcc1e869d3fccf79cdc8be4_02bcf6ec-b9db-4015-a42b-ae8b64e2a859.jpg?v=1788741985","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-46746-cobalt-jobber-drill-bit-wire-76","provider":"Voomi Supply","version":"1.0","type":"link"}
