It is manufactured from high speed steel with a bright, uncoated finish and features a standard 118-degree split-point tip geometry with web thinning for improved penetration and reduced walking on entry. The straight-cylindrical shank measures 0.125 inches in diameter, the overall length is 2.75 inches, and the flute length is 1.625 inches. The two-flute spiral design with a regular spiral type provides efficient chip evacuation during drilling operations. This bit is suited for use by maintenance technicians, pipefitters, electricians, HVAC installers, and general trade professionals who require a reliable jobber-length bit for everyday hole-making tasks.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for drilling in steel, cast iron, non-ferrous metals, superalloys, and titanium. It is well-suited for light to moderate production drilling on the bench, in the field, or during equipment installation and service. The 13xD flute-to-diameter ratio and tapered web configuration make it appropriate for a wide range of metal-drilling applications common in mechanical, electrical, and plumbing trades. It is sold individually and must be ordered in multiples of 12.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction provides durability across a range of metal workpiece materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning reduces thrust and improves centering on entry\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose use without added coating cost\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute promotes consistent chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard 3-jaw drill chucks\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for jobber-length drill bit geometry and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length replacement or stock drill bit for use in standard 3-jaw chucks on handheld drills, drill presses, and milling machines. Compatible workpiece materials include steel, cast iron, non-ferrous metals, superalloys, and titanium as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified tradesperson familiar with rotating cutting tools and applicable shop safety practices. Secure the shank fully in the chuck and confirm the bit is centered before applying feed pressure. Coolant through is not supported on this bit, so appropriate cutting fluid applied externally is recommended when drilling harder alloys. Inspect the cutting edges for wear or damage before each use and replace when point geometry is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.625 inches\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: R10H-R18H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5998358\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51692962808114,"sku":"5998358","price":50.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac335c1d53632e99459aa82e5500dfd1_5d0474db-35a4-4ed8-9754-bda2a32ac076.jpg?v=1788305522","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998358-1-8-inch-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
