Built from cobalt high speed steel with an oxide and straw finish, it delivers improved heat resistance and extended tool life compared to standard HSS bits. The 135-degree split point geometry reduces walking on entry and lowers thrust requirements, making it well suited for production drilling and repetitive hole-making operations. The web-thinned, tapered-web construction keeps cutting forces low. Overall length is 2.625 inches, flute length is 1.5 inches, and the straight cylindrical shank measures 0.1110 inch in diameter.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for drilling steel, cast iron, non-ferrous metals, and similar workpiece materials classified under material codes P, M, K, N, and S. It fits standard drill chucks and collet systems that accept straight-shank tooling. Typical applications include maintenance and repair work, light fabrication, and production drilling where a small-diameter cobalt bit is required. The 14xD flute-to-diameter ratio provides adequate chip clearance for the hole depths typical in jobber-length applications. It meets ANSI standards and carries NAS 907 specification designation, making it appropriate for aerospace-adjacent and precision metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high speed steel construction for improved heat and wear resistance in steel drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking on entry and lowers feed force requirements\u003c\/li\u003e\n  \u003cli\u003eOxide and straw coating provides corrosion resistance and mild lubricity\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design reduces cutting resistance at the chisel edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral flute with 14xD ratio for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards and NAS 907 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard drill chucks and collet holders accepting 0.1110-inch straight-cylindrical shanks.

Power down and de-energize the machine before changing bits. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting this bit does not support coolant-through delivery. Dispose of worn tooling per shop policy and inspect the cutting edges before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 34\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Straw\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, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral, 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: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 14xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Material Codes P, M, K, N, S)\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: R10CO-R15CO-R18CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5997755\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51714394194226,"sku":"5997755","price":59.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_8db62e1a-5822-4d5e-a838-740b15ae1f2a.jpg?v=1788500834","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997755-no-34-cobalt-jobber-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
