It measures 3.10 mm (0.122 inch) in diameter with a 135-degree split point geometry and a web-thinned, tapered web configuration that reduces thrust and improves self-centering on entry. The straw oxide\/bronze coating provides baseline heat resistance and lubricity. With an overall length of 2-9\/16 inches (65.00 mm) and a flute length of 1-27\/64 inches (36.00 mm), it fits standard drill chucks and is built to DIN 338 and ANSI specifications. Machinists, maintenance technicians, and fabricators use this bit for production and repair drilling in ferrous and non-ferrous metals.\u003c\/p\u003e\n\u003cp\u003eThe 6000662 is suited for drilling steel, cast iron, aluminum, and non-ferrous alloys in both shop and field settings. Its Series 2ACO designation places it in a heavy-duty grade jobber line intended for use where standard HSS bits wear too quickly. The 12xD flute-to-diameter ratio delivers efficient chip evacuation in moderate-depth holes. Compatible workpiece material categories include P (steel), M (stainless), K (cast iron), N (non-ferrous), and S (heat-resistant alloys) per ISO material coding. This bit is used in drill presses, CNC machining centers, and hand drills by machinists and maintenance trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for extended tool life in hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces walking and lowers drilling thrust\u003c\/li\u003e\n  \u003cli\u003eStraw oxide\/bronze coating adds surface hardness and heat resistance\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, 2-flute design with 12xD flute ratio for efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank (3.10 mm \/ 0.122 inch) fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 and ANSI standards for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting straight-shank bits at 3.10 mm (0.122 inch) shank diameter.

Secure the straight shank firmly in the drill chuck and verify concentricity before drilling. Use appropriate cutting fluid or coolant when drilling steel or stainless to extend tool life and prevent work hardening. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.10 mm (0.122 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-9\/16 inches (65.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-27\/64 inches (36.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.10 mm (0.122 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1418 inches (29 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.4173 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint 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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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 Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw Oxide\/Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P, M, K, N, S material groups)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2ACO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 338, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty General Purpose\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: 6000662\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51695662006578,"sku":"6000662","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_f2c38184-63f2-4c5e-a9b2-0640454b91f7.jpg?v=1788337249","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000662-jobber-drill-3-10mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
