Built to M42 cobalt steel with a gold oxide coating, this bit delivers extended tool life in applications where standard high-speed steel falls short. The 135-degree split point starts on contact without a center punch, and the web-thinned, tapered web design reduces thrust and improves chip evacuation. At 1.0 inch overall length with a 0.25-inch flute length, this is a precision small-diameter bit suited for metalworking trades, aerospace maintenance, and precision fabrication shops.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for drilling titanium and other hard workpiece materials where M42 cobalt is the specified grade. The straight-cylindrical shank at 0.0210 inches diameter fits standard drill chucks and collet-style holders used in hand drills, drill presses, and CNC applications. Series 550 designation places it within Chicago-Latrobe's heavy-duty line, built to DIN 338 and NAS 907 Type J standards. Typical install environments include aerospace sheet metal work, precision machining, and any application requiring repeatable accuracy in small wire-gauge hole sizing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for drilling titanium and other hard materials\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating extends cutting edge life and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003e135-degree standard split point for self-starting entry without center punching\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling thrust on small-diameter bores\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute promotes chip clearance in deep holes\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J standards for aerospace and industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit for use in applications requiring wire gauge size 75 (0.0210 inches) holes, compatible with any drill chuck or collet accepting a 0.0210-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by machinists, toolroom technicians, or qualified metalworking tradespeople. Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation, and verify chuck runout is within tolerance for small-diameter work. Disconnect power to the drill or machine before changing bits. Do not exceed recommended feed rates for the workpiece material, as small-diameter cobalt bits are susceptible to breakage under lateral load.\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: 75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0210 inches\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: Gold Oxide\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: Standard Web-Thinned\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\u003eFlute Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0210 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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: Titanium\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0007 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: 46745\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51748343578930,"sku":"46745","price":79.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e18f3a73fcc1e869d3fccf79cdc8be4_1e4589fb-bfc0-432a-92a5-8f9e7ad8cf8d.jpg?v=1788892710","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-46745-cobalt-jobber-drill-bit-75","provider":"Voomi Supply","version":"1.0","type":"link"}
