Ground to a 135-degree split point with web thinning, it starts on contact without a center punch and reduces walking on hard surfaces. The straight cylindrical shank measures 5.70 mm (0.2244 inches) in diameter and fits standard drill chucks. An oxide and straw coating provides lubricity and heat resistance during extended drilling cycles. At 3-21\/32 inches overall length with a 2-1\/4 inch flute length, the 6000743 is a practical daily-use bit for fabricators, machinists, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is suited for production and maintenance drilling in ferrous metals, stainless steel, cast iron, aluminum, and non-ferrous alloys. The DIN 338 specification and ANSI standard compliance make it a direct fit wherever metric jobber geometry is specified. Typical applications include structural steel fabrication, sheet metal work, and general machine shop operations requiring a 5.70 mm hole in a wide range of workpiece materials including steel, cast materials, and light alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt HSS construction for improved heat resistance and hardness in steel drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering starts and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eOxide and straw coating reduces friction and extends cutting life\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, 2-flute design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard 3-jaw and keyless drill chucks\u003c\/li\u003e\n  \u003cli\u003eDIN 338 specification with ANSI compliance for consistent geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting a 5.70 mm (0.2244 inch) straight shank.

A licensed machinist or qualified technician should set appropriate feed and speed rates for the workpiece material to avoid overheating the cutting edge. Do not use excessive feed pressure; let the split point geometry do the work. Eye protection and chip guards are required per standard shop safety practice.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.70 mm (0.2244 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-21\/32 inches (3.6563 inches \/ 93.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-1\/4 inches (2.2500 inches \/ 57.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.70 mm (0.2244 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.2441 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\u003ePoint Type\u003c\/strong\u003e: Standard split point, web-thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular spiral, 2-flute\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\u003c\/strong\u003e: Oxide and straw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, web-thinned\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 10xD\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: 6000743\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51709296640306,"sku":"6000743","price":18.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/758de141a9fc20af5d344d75acdd3f69_69fe2cb6-6fa4-4343-9878-4b0f55f421eb.jpg?v=1788454151","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6000743-cobalt-jobber-drill-5-70mm","provider":"Voomi Supply","version":"1.0","type":"link"}
