It measures 9.10 mm (0.3583 inches) in diameter with an overall length of 4-59\/64 inches (125 mm) and a flute length of 3-3\/16 inches (81 mm). The 135-degree split point reduces walking on entry and decreases the thrust force needed to start a hole. A straw oxide finish provides mild lubricity and heat resistance. This bit is suited for professional machinists, tool-and-die workers, maintenance technicians, and fabricators who drill steel and similar metals in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is built for drilling into steel, cast iron, non-ferrous metals, and high-temperature alloys, covering Primary Workpiece Material Codes P, M, K, N, and S under the DIN 338 and ANSI standards. The 9xD flute-to-diameter ratio provides adequate chip clearance for moderate-depth holes. The straight cylindrical shank with zero flats is compatible with standard three-jaw drill chucks on drill presses, CNC machining centers, and handheld power drills. The web-thinned, tapered web construction reduces cutting resistance and extends tool life in repetitive drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction rated for heavy-duty service in steel and hard alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree standard split point reduces drill walk and lowers required feed pressure\u003c\/li\u003e\n  \u003cli\u003eStraw oxide finish adds surface hardness and mild lubricity without coolant-through requirement\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces cutting torque and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRegular right-hand spiral flute with 9xD ratio for effective chip clearance at jobber depth\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank (9.1 mm) fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 and ANSI standards for consistent dimensional tolerances\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 any standard drill chuck accepting a straight cylindrical shank.

Secure the straight shank firmly in a properly sized three-jaw chuck before operation and verify chuck runout is within acceptable limits to prevent premature edge wear. Disengage and lock out all power sources before changing tooling. Do not exceed the rated maximum drilling depth of 3.189 inches to avoid chip packing and bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.10 mm (0.3583 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\u003eOverall Length\u003c\/strong\u003e: 4-59\/64 inches (125 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-3\/16 inches (81 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.189 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3583 inches (9.1 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7323 inches (44 mm)\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, Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical, 0 Flats\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: 2ACO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 338, ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose, Heavy Duty Grade\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: 6000577\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51692439961906,"sku":"6000577","price":32.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_17bddbe9-abe5-4642-a666-64fd91b73a25.jpg?v=1788297493","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000577-cobalt-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
