Built from M42 cobalt high-speed steel and finished with a gold oxide coating, this bit handles demanding applications where standard HSS tooling falls short. The 135-degree split point starts on contact without a center punch, reducing walking on hard surfaces. At 1-3\/8 inches overall length with a 0.0310-inch diameter, it is sized for wire gauge #68 work. The web-thinned, tapered web design improves chip evacuation and lowers thrust during drilling. Two spiral flutes in a regular helix move chips efficiently out of the bore.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for trade and industrial applications requiring precision small-diameter holes in titanium, stainless steel, hardened alloys, and other difficult workpiece materials. It is commonly used by machinists, maintenance technicians, and fabricators working on aerospace components, instrumentation assemblies, and structural metalwork where tight-tolerance holes are required. The straight-cylindrical shank fits standard drill chucks and collets without modification. Series 550 heavy-duty grade construction makes it appropriate for both manual and CNC drilling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating reduces friction and provides visual wear indication\u003c\/li\u003e\n  \u003cli\u003e135-degree split point eliminates center-punching and reduces drill walk\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and NAS 907 Type J standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-duty drill bit compatible with any drill chuck or collet accepting a 0.0310-inch straight-cylindrical shank.

Secure the shank fully in a properly sized chuck or collet before use, and verify spindle runout is within acceptable limits to prevent bit breakage at this diameter. Apply cutting fluid appropriate for the workpiece material to extend tool life and maintain hole tolerance. Avoid excessive feed pressure, which can deflect or snap small-diameter cobalt bits.\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: #68\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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 Split Point\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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.375 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: 0.0310 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.875 inches\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: -0.0005 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\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: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 46738\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51749070962994,"sku":"46738","price":58.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e18f3a73fcc1e869d3fccf79cdc8be4_67618d59-5fe3-4283-91c6-a8d8ec929c8f.jpg?v=1788901766","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-46738-cobalt-jobber-drill-bit-wire-68","provider":"Voomi Supply","version":"1.0","type":"link"}
