It measures 0.0400 inches in diameter with an overall length of 1.625 inches and a flute length of 0.6875 inches. The 135-degree split point reduces walking on entry and requires less feed pressure than a standard 118-degree grind. An oxide and straw finish provides mild lubrication and corrosion resistance during cutting. This bit is sized for precision work and is typically installed by machinists, maintenance technicians, and metalworking tradespeople who need consistent, repeatable hole quality in small-diameter applications.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is suited for production and maintenance drilling in steel, cast iron, aluminum, copper, and other materials covered under material codes P, M, K, N, and S. The 17xD flute-to-diameter ratio and tapered web configuration make it appropriate for through-hole and blind-hole drilling in thin stock, sheet metal, and small machined components. It belongs to the R10CO-R15CO-R18CO series from Precision Twist Drill, which is designed around NAS 907 and ANSI standards for consistent geometry across the series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 60 wire gauge diameter: 0.0400 inches for tight-tolerance small-hole work\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction rated as heavy-duty grade for improved heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust and minimizes bit walk on hard surfaces\u003c\/li\u003e\n  \u003cli\u003eOxide and straw coating provides light lubrication and surface protection\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, right-hand cutting flutes with tapered web for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank at 0.0400 inches diameter fits standard keyless and keyed drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ANSI dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the PRECISION TWIST DRILL R10CO-R15CO-R18CO series.

Secure the workpiece before drilling and confirm the chuck is fully tightened on the straight shank. When drilling steel or hard alloys, use a cutting fluid to extend bit life and maintain hole quality. At 0.0400 inches diameter, avoid excessive lateral force, which can snap the bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0400 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 Bit Grade\u003c\/strong\u003e: Heavy Duty\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 Split Point with Web Thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating and Finish\u003c\/strong\u003e: Oxide and Straw\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.6875 inches (11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6875 inches (11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.625 inches (1-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.9375 inches (15\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 17xD\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel and multi-material (P, M, K, N, S codes)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10CO-R15CO-R18CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907, ANSI\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: 0.042 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: 5997776\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51720960508210,"sku":"5997776","price":66.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_98ea62a4-a3f9-4909-b7f7-0917d002025c.jpg?v=1788571500","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997776-no-60-cobalt-jobber-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
