Built from high speed steel with a steam oxide coating, it is designed for general-purpose drilling in a wide range of materials. The 135-degree split point reduces walking on entry and lowers thrust requirements compared to a standard 118-degree point. With an overall length of 2.375 inches and a 1.375-inch spiral flute, this bit is installed by machinists, maintenance technicians, and metalworking professionals in both shop and field environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in ferrous and non-ferrous metals, including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits the general-purpose jobber-length category and is appropriate for use in standard drill presses, CNC machining centers, and hand drills where a straight cylindrical shank is accepted. The Series R18B designation and NAS 907 specification make it a recognized standard in aerospace and industrial maintenance applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 39 with a decimal diameter of 0.0995 inches for precise gauge-standard hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree standard point angle reduces drill walk and lowers entry thrust\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating provides lubricity and basic corrosion resistance during storage and use\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with heavy-duty grade rating for extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web design reduces cutting resistance and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral and 2 flutes; no coolant-through requirement for general shop use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose jobber-length drill bit compatible with any drill chuck or collet accepting a 0.0995-inch straight cylindrical shank.

Secure the shank fully in the chuck before operation and confirm the workpiece is clamped to prevent rotation. Cutting fluid or light oil is recommended when drilling stainless steel, cast iron, or titanium to extend bit life. Inspect the cutting edges for wear before each use and replace when the point shows chipping or significant dulling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 39\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0995 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0995 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 14xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10B, R15B, R18B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5999168\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51702587621682,"sku":"5999168","price":45.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7da465a3340ea6a9db91bc6a63822e95_065b8c5a-a60e-4277-a559-cea6ad79fd2c.jpg?v=1788412128","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999168-jobber-drill-bit-39-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
