Ground from high speed steel (HSS) and finished with a steam oxide coating, this bit handles steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The 118-degree standard point angle suits most shop and field drilling tasks. At 3.875 inches overall length with a 2.625-inch spiral flute, the bit delivers a 12xD flute-to-diameter ratio that provides adequate chip clearance and rigidity for production and maintenance drilling. It carries a wire gauge size of 1, equivalent to 0.2280 inches in decimal. The web-thinned, tapered-web design reduces entry force and improves centering on the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for professional metalworking environments including fabrication shops, maintenance and repair operations, and field service. It handles drilling in steel, stainless steel, cast iron, non-ferrous metals, and superalloys including titanium. The right-hand cut, two-flute spiral design with straight-cylindrical shank fits standard drill chucks without modification. Part of the Precision Twist Drill Series R10-R15-R18 line, it is built to ANSI specifications for consistent geometry across production runs. Sold individually, it is appropriate for both bench drill presses and handheld drilling applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction with steam oxide coating for reduced friction and surface protection\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered-web geometry for easier entry\u003c\/li\u003e\n  \u003cli\u003eWire size 1 (0.2280 inches decimal) straight-cylindrical shank fits standard three-jaw chucks\u003c\/li\u003e\n  \u003cli\u003eTwo-flute right-hand spiral design with 2.625-inch flute length for effective chip evacuation\u003c\/li\u003e\n  \u003cli\u003e12xD flute-to-diameter ratio supports drilling depth up to 2.625 inches\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI specifications; Series R10-R15-R18 general-purpose grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks accepting a 0.2280-inch straight-cylindrical shank.

Secure the workpiece and confirm chuck is tightened before operation. Follow applicable shop safety protocols including eye protection and appropriate cutting fluid use when drilling stainless steel or superalloys. Inspect the bit for wear or chipping before each use and replace if cutting geometry is compromised.\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: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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\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\u003ePoint Type\u003c\/strong\u003e: Standard\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: 0.2280 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\u003eOverall Length\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 12xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10-R15-R18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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\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 Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5998450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51723853463858,"sku":"5998450","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2bbd17554f8298fe95bb319a732ccea_563b26c8-1c77-4162-a616-962252a21ab7.jpg?v=1788608783","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998450-jobber-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
