It is a No. 42 wire-gauge bit with a 3\/32-inch (0.0935-inch decimal) diameter, ground to a 135-degree split-point angle for fast engagement and reduced walking on hard surfaces. The bit is manufactured from high-speed steel with a steam oxide coating that provides lubricity and mild corrosion resistance. At 2.25 inches overall length with a 1.25-inch flute, it fits standard drill chucks and is sized for production and maintenance drilling tasks performed by machinists, tool-and-die workers, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its regular spiral, two-flute geometry and tapered web with web thinning support efficient chip evacuation in both hand-held and machine-mounted applications. The straight cylindrical shank seats cleanly in keyless or keyed drill chucks on bench-top drill presses, CNC machines, and hand drills. It carries ANSI and NAS 907 specification compliance, making it appropriate for aerospace and heavy industrial work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 42 wire-gauge size, 0.0935-inch decimal diameter, 3\/32-inch fractional equivalent\u003c\/li\u003e\n\u003cli\u003e135-degree split-point angle reduces thrust and minimizes bit walking on hard surfaces\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with steam oxide coating for lubricity and mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral with tapered, web-thinned web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight cylindrical shank fits standard drill chucks without modification\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 specifications; rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or production-run jobber-length drill bit conforming to ANSI and NAS 907 standards, suitable for use in standard drill chucks accepting a 3\/32-inch straight cylindrical shank across bench-top, CNC, and handheld drilling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians. Secure the shank fully in the chuck and confirm runout before drilling. Power down or de-energize any machine tool before changing bits. Do not exceed the rated speed range for the workpiece material, and use appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to prevent work hardening and premature bit wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 3\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.0935 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0935 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\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\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\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\u003eSeries\u003c\/strong\u003e: R10B-R15B-R18B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy Duty Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 5999177\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691456823602,"sku":"5999177","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7da465a3340ea6a9db91bc6a63822e95_cc84899d-ddeb-4544-8ce1-b6b3d82e6343.jpg?v=1788285335","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999177-jobber-drill-bit-no-42","provider":"Voomi Supply","version":"1.0","type":"link"}
