Manufactured from cobalt high-speed steel for heavy-duty cutting performance, the bit features a web-thinned, tapered web configuration that reduces thrust and improves chip clearance at the point. It is a right-hand cutting, regular spiral flute design with a straight cylindrical shank sized at 0.3770 inches. At 5 inches overall length with a 3.625-inch flute length, this bit is suited for production and maintenance drilling in steel and other ferrous and non-ferrous materials. Licensed machinists, tool-room technicians, and industrial maintenance mechanics are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for drilling steel as its primary workpiece material, with a workpiece material code covering P, M, K, N, and S material groups, making it applicable across mild steel, alloy steel, stainless steel, cast iron, non-ferrous metals, and heat-resistant superalloys. It is listed under Series R10CO-R15CO-R18CO and meets NAS 907 and ANSI standards. Typical applications include through-hole and blind-hole drilling in fabrication shops, maintenance facilities, and production environments where a reliable general-purpose cobalt drill is required. The 10xD flute-to-diameter ratio delivers adequate chip evacuation for moderate-depth holes up to the maximum drilling depth of 3.625 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction rated for heavy-duty drilling in steel and difficult materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces walking and lowers required thrust force\u003c\/li\u003e\n  \u003cli\u003eStraw oxide\/bronze proprietary coating provides lubricity and heat resistance during cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral flute with tapered web for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank at 0.3770 inches fits standard drill chucks and toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ANSI standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification cobalt jobber drill conforming to NAS 907 and ANSI standards, compatible with any standard drill chuck or toolholder accepting a 0.3770-inch straight shank.

Secure the workpiece firmly before drilling and confirm chuck runout is within acceptable limits to prevent premature edge wear. Apply cutting fluid or coolant appropriate for the workpiece material when drilling steel to extend tool life. Follow ANSI safety standards for rotating tool operation, including proper eye protection and workpiece clamping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3770 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw Oxide\/Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3770 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: 3.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 10xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Material Codes P, M, K, N, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10CO-R15CO-R18CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 5999075\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51710444765490,"sku":"5999075","price":36.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43023b3e6b6bab88a536782a7f7f19eb_e2de09a6-bc7c-478e-b9ee-c9d2f9e4881d.jpg?v=1788467040","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5999075-cobalt-jobber-drill-bit-v","provider":"Voomi Supply","version":"1.0","type":"link"}
