Built to MVS Series standards, it features a TiAlN coating that extends tool life in high-heat, high-speed operations. The drill point is ground to 140 degrees with X-Thinning geometry, which reduces thrust force and improves centering on entry. At 4.5118 inches overall length with a 2.5039-inch flute length and a 15xD flute-to-diameter ratio, this bit reaches depths that standard-length drills cannot. It is sold individually and installed by machinists and tool-and-die professionals in CNC and manual drill press setups.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for deep hole drilling, cross hole drilling, stack drilling, and general drilling in a wide range of workpiece materials. It is suited for use in production machining, aerospace component fabrication, and structural steel work where extended reach and hole quality are critical. The right-hand helical flute promotes efficient chip evacuation in continuous cuts. Coolant-through capability supports through-spindle coolant delivery for deep hole operations where chip clearance and heat management are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN coating provides heat and wear resistance in high-speed steel and stainless steel cutting\u003c\/li\u003e\n\u003cli\u003e140-degree split point with X-Thinning reduces entry thrust and improves hole location accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep hole and stack drilling\u003c\/li\u003e\n\u003cli\u003e15xD flute-to-diameter ratio enables extended reach beyond standard drill bit capability\u003c\/li\u003e\n\u003cli\u003eCylindrical shank with 0.2362-inch diameter fits standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand helical flute with parallel web configuration promotes consistent chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use on steel, stainless steel, superalloys, titanium, tempered steel, hardened steel, cast iron, carbon steel, structural steel, iron, aluminum, aluminum alloy, brass, bronze, high-strength bronze, and copper workpieces. Conforms to ISO specification designation. Designed for CNC machining centers, drill presses, and manual machines equipped with through-spindle or external coolant systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine power isolated. Secure the cylindrical shank in a properly sized collet or drill chuck to the depth recommended by the machine manufacturer to avoid runout. Verify coolant flow path is clear before engaging through-spindle coolant. Follow shop-floor speeds and feeds guidance appropriate for the workpiece material and machine capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1260 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 3.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5118 inches (114.6 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.5039 inches (63.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6.0 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7717 inches (45.0 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.9134 inches (48.60 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\u003eDrill Point Length\u003c\/strong\u003e: 0.0236 inches (0.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 15xD\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, 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241637\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 10555279\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51699718816050,"sku":"10555279","price":341.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c379bcb8d08cb8569efb7441d13f2935_ce19d118-0b6f-4600-bffa-cf8890bfe187.jpg?v=1788379753","url":"https:\/\/voomisupply.com\/products\/mitsubishi-10555279-extra-length-drill-bit-0-1260in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
