Built to Series 550 standards, this bit carries an M42 cobalt steel construction with a gold oxide coating that improves lubricity and extends tool life under demanding conditions. The 135-degree split point reduces walking and allows the bit to engage the workpiece without a center punch. With an overall length of 3-7\/8 inches and a flute length of 2-5\/8 inches, it fits standard drill chucks and handles a wide range of production and maintenance applications. It is installed by machinists, maintenance technicians, and metal fabricators working in shop and field environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for drilling titanium and other hard metals where standard high-speed steel tooling underperforms. The right-hand spiral flute clears chips efficiently during through-hole and blind-hole operations. The straight-cylindrical shank with a diameter of 0.2210 inches seats securely in standard three-jaw chucks. It conforms to DIN 338 and NAS 907 Type J standards, making it suitable for aerospace, industrial maintenance, and general metalworking applications where dimensional accuracy and bit integrity are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for drilling titanium and hard alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirement\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating improves lubricity and resists heat buildup\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 and NAS 907 Type J standards\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use jobber drill bit for standard three-jaw chucks accepting a 0.2210-inch straight-cylindrical shank.

Secure the shank fully in the chuck and verify runout before starting the cut. Use appropriate cutting fluid or coolant when drilling titanium or hardened alloys to manage heat and extend tool life. Inspect the split point for chipping after use on hard materials before returning the bit to service.\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: No. 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2210 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: Split\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2210 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: -0.0007 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: 0.034 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: 46672\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51752877916466,"sku":"46672","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e18f3a73fcc1e869d3fccf79cdc8be4_7613a78c-fb43-4b4f-ad68-0920e482e1d3.jpg?v=1788930794","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-46672-cobalt-jobber-drill-bit-no-2","provider":"Voomi Supply","version":"1.0","type":"link"}
