Built to MVS series standards, it features a TiAlN coating for extended tool life and heat resistance at high cutting speeds. The drill point is ground to 140 degrees with X-Thinning geometry, reducing entry thrust and improving chip evacuation. With an overall length of 12.2677 inches and a flute length of 9.9843 inches, this bit reaches depths up to 8.626 inches. The helical, right-hand flute and parallel web configuration make it well suited for precision work in tight-tolerance bores. Installed by machinists and CNC operators in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for a broad range of workpiece materials with steel as the primary application material. Secondary materials include stainless steel, superalloys, titanium, structural steel, tempered steel, iron, high strength bronze, hardened steel, copper, cast iron, carbon steel, bronze, brass, aluminum, and aluminum alloy. Typical use cases include deep hole drilling, cross hole drilling, stack drilling, and standard through-hole operations across aerospace, automotive, and general metalworking applications. The 25xD flute-to-diameter ratio supports extended reach without sacrificing rigidity in the shank zone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN coating improves heat resistance and extends tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree X-Thinned drill point reduces entry thrust and centers the bit accurately\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the tip for deep hole chip clearance\u003c\/li\u003e\n  \u003cli\u003e25xD flute-to-diameter ratio enables drilling depths up to 8.626 inches\u003c\/li\u003e\n  \u003cli\u003eCylindrical shank at 0.3937 inches diameter fits standard collet and drill chuck toolholding\u003c\/li\u003e\n  \u003cli\u003eRight-hand helical flute with parallel web for consistent chip evacuation and bore finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production cutting tool for CNC machining centers, drill presses, and deep hole drilling setups requiring a 0.3425-inch diameter carbide drill with a cylindrical shank and coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. The machine spindle must be fully stopped and the tool changer or spindle lock engaged before loading or changing the bit. Verify collet or chuck bore matches the 0.3937-inch shank diameter before clamping. Confirm coolant-through passages are clear and coolant supply pressure is set to the machine specification before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3425 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 8.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12.2677 inches (311.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.9843 inches (253.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 8.626 inches (219.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.1654 inches (55.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0630 inches (1.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 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: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-Thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 25xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 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: MITSUBISHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10556542\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51717458788658,"sku":"10556542","price":934.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c379bcb8d08cb8569efb7441d13f2935_32d7a421-6089-419c-900b-3f754746883d.jpg?v=1788540804","url":"https:\/\/voomisupply.com\/products\/mitsubishi-10556542-extra-length-drill-bit-0-3425in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
