Built from cobalt high-speed steel with an oxide and straw finish, this bit delivers improved heat resistance and longer tool life compared to standard HSS drills. The 135-degree split point reduces walking on entry and requires no center punch on flat stock. At 2.625 inches overall length with a 1.5-inch flute, it handles typical jobber-depth holes in sheet and structural steel. This bit is a standard tool for machinists, maintenance techs, and fabricators working with ferrous and non-ferrous metals.\u003c\/p\u003e\n\u003cp\u003eThe 5997759 is suited for drilling steel, stainless, cast iron, non-ferrous alloys, and high-temp aerospace alloys across a range of workpiece material codes including P, M, K, N, and S classifications. Its regular spiral flute and tapered web with web thinning make it effective in drill presses, CNC machines, and hand-held power drills. It is a general-purpose heavy-duty bit appropriate for both production floor and maintenance shop use. The straight cylindrical shank fits standard drill chucks without any adapter. The series designation R10CO-R15CO-R18CO identifies its placement in the PRECISION TWIST DRILL cobalt jobber line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 35 wire gauge size, 0.110 inch diameter, straight cylindrical shank\u003c\/li\u003e\n  \u003cli\u003e135-degree standard split point reduces bit walking and eliminates center-punching on flat stock\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction with oxide and straw coating for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute, right-hand cutting direction, 1.5 inch maximum drilling depth\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NAS 907 standards; rated for steel and multi-material general-purpose drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the PRECISION TWIST DRILL Series R10CO-R15CO-R18CO cobalt jobber line.

Power down and de-energize any drill press or CNC spindle before changing tooling. Secure the shank fully in the chuck and verify runout before cutting. Use appropriate cutting fluid or coolant for the workpiece material to preserve edge life; this bit does not support coolant-through delivery.\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. 35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1100 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 Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/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: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1100 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 14xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P, M, K, N, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy Duty\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\u003eWeight\u003c\/strong\u003e: 0.04167 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: 5997759\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51699069092146,"sku":"5997759","price":59.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd6336b34c1d0261f5eb3b4d3e77059f_886aa524-69dd-4d9d-b983-18a51605636d.jpg?v=1788371928","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997759-cobalt-jobber-drill-no-35","provider":"Voomi Supply","version":"1.0","type":"link"}
