Built from high-speed steel (HSS) with a steam oxide coating, this bit is designed for general-purpose drilling in a wide range of metallic and hard materials. The 118-degree standard point angle and two-flute spiral configuration provide accurate entry and efficient chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. With an overall length of 3.125 inches and a flute length of 2 inches, it fits the jobber-length class used daily in machine shops, maintenance shops, and fabrication environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It performs in both handheld drill and drill press setups. The R18A series designation and NAS 907 specification make it a recognized standard in production and maintenance drilling applications where consistent hole quality and dimensional accuracy are required. It is a solid choice for machinists, millwrights, pipefitters, and maintenance technicians working with metal stock or structural components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge No. 24 diameter — 0.1520 inches — for precise hole sizing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction withstands heat generated during metal drilling\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and provides light corrosion resistance\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for accurate self-starting on flat and curved surfaces\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design promotes efficient chip removal\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces thrust and improves cutting performance\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards and NAS 907 specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces.

Secure the straight shank firmly in the chuck before operation to prevent slipping under load. Use cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to manage heat buildup, as this bit does not support coolant-through delivery. Inspect the cutting edges for wear or chipping before each use and replace bits that show visible damage to maintain hole accuracy and operator safety.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1520 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1520 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: R10A \/ R15A \/ R18A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907, ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 5999339\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51701097857330,"sku":"5999339","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb0d3aa62b12a911c87b71fb6c8893a6_f682807b-dd08-403c-bf41-26d5b227fd45.jpg?v=1788398177","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999339-no-24-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
