It features a 135-degree split-point angle with web thinning for self-centering starts and reduced thrust on entry. The straw oxide finish improves lubricity and surface hardness. At 3.125 inches overall length with a 2-inch flute, this bit is built for general-purpose drilling in steel and other demanding workpiece materials. It is commonly installed and used by machinists, maintenance mechanics, and fabricators working in production or field environments.\u003c\/p\u003e\u003cp\u003eThis bit is rated for primary workpiece materials classified under material codes P, M, K, N, and S, covering a range of steels, cast irons, non-ferrous metals, and high-temperature alloys. The regular spiral flute design promotes chip evacuation in through-hole and blind-hole applications. It conforms to ANSI and NAS 907 standards and falls within the R10CO-R15CO-R18CO series from Precision Twist Drill, making it appropriate for operations requiring consistent hole quality in metalworking and fabrication settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 22 wire size, 0.1570-inch decimal diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree point angle with web-thinned tip for self-centering and reduced walking\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction for heat resistance and extended tool life in steel drilling\u003c\/li\u003e\n\u003cli\u003eStraw oxide finish improves surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003eRegular spiral, two-flute design promotes chip clearance in both through-hole and blind-hole work\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks; no flats\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and NAS 907 specifications for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the R10CO-R15CO-R18CO series.

Always secure the workpiece before drilling and confirm the chuck is properly tightened on the straight shank. Power down and de-energize any equipment before changing bits. Coolant-through is not supported on this bit; use external cutting fluid when drilling hardened or heat-sensitive materials to extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1570 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\u003eCoating\/Finish\u003c\/strong\u003e: Straw Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1570 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.0 inches\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: Regular Spiral\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Codes P, M, K, N, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 13xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NAS 907\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\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5997717\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51718066176306,"sku":"5997717","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_9e00af02-bd03-48a5-b26e-5d44dbb7897f.jpg?v=1788549291","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997717-cobalt-jobber-drill-no-22","provider":"Voomi Supply","version":"1.0","type":"link"}
