It measures 9.80 mm (0.3858 inches) in diameter with an overall length of 5-15\/64 inches (5.2344 inches) and a flute length of 3-27\/64 inches (3.4219 inches). The 135-degree split point reduces walking and allows drilling to start without a center punch in most setups. An oxide and straw finish provides light lubricity and corrosion resistance during service. This bit is suited for machinists, tool-and-die shops, and maintenance technicians running hand-held or machine-spindle operations.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is built for general-purpose through-hole and blind-hole drilling in ferrous and non-ferrous materials. The 9xD flute-to-diameter ratio provides adequate chip evacuation in typical depth applications. With a straight cylindrical shank at 9.80 mm (0.3858 inches), it seats directly in standard keyless or keyed drill chucks without an adapter. Primary workpiece material classifications include steel, stainless, cast iron, non-ferrous, and heat-resistant alloys (P, M, K, N, S codes per ISO material grouping). The two-flute regular spiral geometry handles a broad range of shop materials without requiring specialized toolpaths.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt HSS construction for elevated heat resistance in tough ferrous and exotic-alloy drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and minimizes bit walk on entry\u003c\/li\u003e\n  \u003cli\u003eOxide and straw coating adds surface lubricity and light corrosion protection\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design improves chip clearance and reduces cutting torque\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 and ANSI standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber drill for use in standard drill chucks accepting a 9.80 mm straight shank.

Ensure the workpiece is clamped or fixtured to prevent rotation. Apply cutting fluid appropriate to the workpiece material to extend tool life, particularly when drilling stainless or alloy steel. Inspect the cutting edges for wear or chipping before each use and replace if the point geometry is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.80 mm (0.3858 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-15\/64 inches (5.2344 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-27\/64 inches (3.4219 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9.80 mm (0.3858 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.4252 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\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\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\u003eMaterial\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\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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 9xD\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, Stainless, Cast Iron, Non-Ferrous, Heat-Resistant Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 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: 6000598\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51695098659122,"sku":"6000598","price":34.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_c396df8b-04e6-40b1-8ef8-89378866cd8c.jpg?v=1788331321","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000598-cobalt-jobber-drill-9-80mm","provider":"Voomi Supply","version":"1.0","type":"link"}
