Built from high speed steel with a steam oxide coating, the bit features a 135-degree split point that reduces walking on contact and allows drilling to start without a center punch on most setups. The spiral flute geometry and right-hand cut produce clean chip evacuation in ferrous and non-ferrous materials. With an overall length of 3.75 inches and a flute length of 2.5 inches, this is a standard jobber proportions bit suited for production and maintenance drilling tasks performed by machinists and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It is well-suited for use in drill presses, CNC machining centers, and hand-held power drills where a straight-cylindrical shank is required. The R18B series designation and NAS 907 specification make it a recognized standard in aerospace and industrial maintenance environments. Typical applications include through-hole and blind-hole drilling in fabrication shops, HVAC equipment manufacturing, and general metalworking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size No. 6 at 0.2040 inches decimal diameter for precision hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and minimizes bit walking on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating improves lubricity and provides basic corrosion resistance during storage\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design with regular spiral flute and 2-flute configuration for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.2040 inches diameter fits standard drill chucks without an adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style general-purpose jobber drill bit compatible with any drill press, hand drill, or machining center accepting a straight-cylindrical shank.

Secure the shank fully in the chuck before operation to prevent runout or bit pull-out during drilling. Match spindle speed to workpiece material and bit diameter using published cutting-speed tables for high speed steel tooling. Do not force the bit through hard material at excessive feed rates, as this will shorten tool life and can cause breakage.\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. 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy Duty Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10B-R15B-R18B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: 5997660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51711760695602,"sku":"5997660","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7da465a3340ea6a9db91bc6a63822e95_324a65ca-b11b-46af-b7ed-56ccc3daab99.jpg?v=1788479314","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997660-jobber-drill-bit-no-6","provider":"Voomi Supply","version":"1.0","type":"link"}
