Built from cobalt high-speed steel with an oxide and straw finish, it resists heat and wear during extended use in ferrous and non-ferrous materials. The bit measures 0.0625 inches (1\/16 inch) in diameter with a 1-7\/8 inch overall length and a 7\/8 inch flute length. The 135-degree split point reduces walking at startup and lowers thrust requirements compared to a standard 118-degree point. A straight cylindrical shank and right-hand spiral flute make this bit compatible with standard drill chucks. Web-thinned geometry improves chip evacuation and reduces cutting forces in tougher materials.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for general-purpose drilling in steel, stainless, cast iron, aluminum, and other materials covered under the P, M, K, N, and S workpiece material codes. It is a practical choice for HVAC techs, plumbers, electricians, and maintenance professionals who need a small-diameter bit capable of handling harder alloys without dedicated tooling. The series R10CO-R15CO-R18CO designation places it within Precision Twist Drill's heavy-duty cobalt line, built to NAS 907 and ANSI standards. It is sold individually but requires a minimum order of 12 units per purchase.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for elevated heat and wear resistance in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces walking and lowers feed pressure\u003c\/li\u003e\n  \u003cli\u003eOxide and straw finish provides lubricity and additional surface hardness\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds rigidity to the cutting edge\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 and ANSI standards for dimensional accuracy and material performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eBelongs to Precision Twist Drill series R10CO-R15CO-R18CO.

Secure the workpiece with clamps or a vise before drilling to prevent movement. Use cutting fluid appropriate for the workpiece material to extend bit life and reduce heat buildup. Dispose of worn bits properly and inspect the cutting edge before each use to avoid breakage in small-diameter tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 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\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches (1.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 7\/8 inch (0.8750 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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard Split Point\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\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and Straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P, M, K, N, S codes)\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\u003eSeries\u003c\/strong\u003e: R10CO-R15CO-R18CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: NAS 907 \/ ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 12\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: 5998132\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51698112463154,"sku":"5998132","price":51.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48612cbca6d09eb9dfe2c82cf07b8e8a_8e35f5d8-ccf4-4ee8-b323-af434c6a45ea.jpg?v=1788357869","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5998132-cobalt-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
