Built from M2 high-speed steel with a bronze (straw) coating, it features a 135-degree split-point tip with web thinning for reduced thrust and faster starts without a center punch. The straight shank measures 0.4130 inches in diameter and seats in standard drill chucks. With an overall length of 5.25 inches and a flute length of 3.875 inches, this bit handles drilling depths up to 3.875 inches. A right-hand, regular spiral flute pattern evacuates chips efficiently during operation.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in high-temperature alloys and general metalworking applications. The Series HX10-HX15-HX18 designation covers a range of heavy-duty cutting scenarios found in aerospace, tool-and-die, and industrial maintenance environments. It follows ANSI standards and carries a 9xD flute-to-diameter ratio, making it a practical choice for machinists, maintenance mechanics, and fabricators working with ferrous and non-ferrous metals as well as high-temp alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter Z size — 0.4130 inch decimal equivalent for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces walking and cutting force\u003c\/li\u003e\n\u003cli\u003eM2 high-speed steel construction for hardness and wear resistance at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eBronze (straw) coating provides lubricity and mild heat resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard 3-jaw and keyless drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit in the HX10-HX15-HX18 series, suitable for use in standard drill presses, milling machines, and handheld power drills with compatible chuck capacity for a 0.4130-inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or maintenance professionals familiar with proper speeds and feeds for HSS tooling. Secure the straight shank firmly in the chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Apply appropriate cutting fluid when drilling high-temp alloys or hard steels to extend tool life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Z\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.4130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: M2 High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bronze (Straw)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard with Web Thinning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\u003eOverall Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 9xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy\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: HX10-HX15-HX18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\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: 5995876\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698147459378,"sku":"5995876","price":27.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/164a426c244a50dcd1df57227d075760_95a036ff-45b0-4a31-872c-e8bc030d0c28.jpg?v=1788358464","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995876-letter-z-hss-jobber-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
