The bit is manufactured from high speed steel with a steam oxide coating that provides lubricity and light corrosion resistance during storage and use. A 135-degree split point reduces walking on entry and requires less feed pressure than a standard 118-degree grind. The spiral flute geometry follows a regular helix with a web-thinned, tapered web configuration. Overall length is 2.375 inches with a 1.375-inch flute length and a straight-cylindrical shank. Right-hand cut. Designed for professional use in drill presses, CNC machines, and hand-held power tools.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium — covering ISO material codes P, M, K, N, and S. The 14xD flute-to-diameter ratio and heavy-duty grade make it appropriate for production drilling and maintenance applications alike. It fits standard jobber-length chuck applications and is a common choice for HVAC, mechanical, and fabrication trades when precise small-diameter hole placement is required. Sold individually; minimum order quantity is 12 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 40 wire gauge size — 0.0980 inches decimal diameter\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and cutting force on entry\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating provides lubricity and light rust resistance\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for steel, stainless, cast iron, non-ferrous metals, and superalloys\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web for improved chip clearance\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI standards and NAS 907 specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose OEM-style jobber-length drill bit for use in standard straight-shank drill chucks across drill presses, CNC drilling centers, and hand-held power tools.

Secure the workpiece firmly before drilling and confirm the chuck is properly tightened on the straight-cylindrical shank before starting the spindle. Avoid side-loading the bit, as small-diameter high speed steel bits are susceptible to breakage under lateral force. Follow applicable shop safety practices and machine guarding requirements when operating drilling equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.000 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.375 inches\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\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907, ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10B-R15B-R18B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5999171\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51709653057842,"sku":"5999171","price":44.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7da465a3340ea6a9db91bc6a63822e95_cc6059dd-28e0-4943-9e56-3b79600f470f.jpg?v=1788458802","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999171-jobber-drill-bit-no-40","provider":"Voomi Supply","version":"1.0","type":"link"}
