The bit measures 0.1875 inches (3\/16 inch) in diameter with an overall length of 4.168 inches and a flute length of 2.28 inches. A TiAlN coating provides heat and wear resistance for extended tool life in tough materials. The right-hand helical flute geometry and X-thinned web point support clean, accurate hole entry and efficient chip evacuation, making this bit a reliable choice for machinists and fabricators working in production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for cross hole drilling, standard drilling, and stack drilling operations. Its 8xD flute-to-diameter ratio supports deeper drilling depths up to 1.535 inches in a single pass. The cylindrical shank at 0.236 inches diameter seats securely in standard drill chucks and collet holders. Primary workpiece material is steel, with secondary compatibility across stainless steel, superalloys and titanium, structural steel, tempered steel, iron, high strength bronze, hardened steel, copper, cast iron, carbon steel, bronze, brass, aluminum, and aluminum alloy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in high-load drilling\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle with X-thinning reduces thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal chip flushing and thermal management\u003c\/li\u003e\n\u003cli\u003eRight-hand helical, 2-flute geometry promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMVS Series rated for high performance and high precision grades per ISO specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe 663154 is designed for use in CNC machining centers, drill presses, and manual machines accepting a 0.236-inch cylindrical shank. Verified compatible workpiece materials include steel, stainless steel, superalloys and titanium, structural steel, tempered steel, iron, high strength bronze, hardened steel, copper, cast iron, carbon steel, bronze, brass, aluminum, and aluminum alloy. Suitable tool applications are cross hole drilling, drilling, and stack drilling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with carbide drill bit handling and CNC or manual drill setup. Ensure the machine spindle and workpiece are fully secured before operation. Carbide tooling is brittle — avoid side loading, impact, or interrupted cuts beyond the rated application. Coolant-through capability should be connected to an appropriate coolant supply to realize full tool life and chip management performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 4.76 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.28 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.535 inches\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: 0.034 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.236 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.772 inches\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-Thinning\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 8xD\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: 0.06 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: 663154\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51692659802418,"sku":"663154","price":268.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c379bcb8d08cb8569efb7441d13f2935_e77df617-8cf5-4e3a-bf42-bc56a601f318.jpg?v=1788300743","url":"https:\/\/voomisupply.com\/products\/mitsubishi-663154-extra-length-carbide-drill-bit-0-1875-in","provider":"Voomi Supply","version":"1.0","type":"link"}
