It carries a TiAlN coating to extend tool life under heat and abrasion, making it well suited for dry or minimum-quantity lubrication (MQL) operations. The bit measures 0.2812 inches (9\/32 inches) in diameter with an overall length of 5.642 inches and a flute length of 3.319 inches. The 140-degree split point with X-thinning geometry reduces entry force and improves hole entry accuracy. Coolant-through capability allows internal delivery of cutting fluid directly to the cutting zone. This is a tool installed and operated by machinists and tool-and-die professionals in CNC and manual drill press environments.\u003c\/p\u003e\u003cp\u003eThe 663226 belongs to the MVS Series and is built for cross hole drilling, stack drilling, and standard through-hole drilling operations. Its 8xD flute-to-diameter ratio and maximum drilling depth of 2.301 inches make it appropriate for medium-to-deep hole applications in production environments. The right-hand helical flute with parallel web and X-thinned web configuration supports chip evacuation in interrupted cuts and multi-layer stack setups. The cylindrical shank diameter of 0.315 inches fits standard drill chucks and collet-style toolholders used in CNC machining centers and manual equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN coating for extended tool life in high-heat cutting operations\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle with X-thinning for reduced thrust force and accurate hole entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design for internal cutting fluid delivery at the tip\u003c\/li\u003e\n\u003cli\u003e8xD flute ratio supports drilling depths up to 2.301 inches\u003c\/li\u003e\n\u003cli\u003eRight-hand helical flute with parallel web for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eCylindrical shank at 0.315 inches diameter for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in steel, stainless steel, superalloys, titanium, structural steel, tempered steel, iron, hardened steel, copper, cast iron, carbon steel, bronze, brass, aluminum, and aluminum alloy workpiece materials.

Power down and de-energize the machine spindle before inserting or removing the drill bit from the toolholder or chuck. Verify shank seating and runout before beginning a cut, as misalignment accelerates tool wear and reduces hole quality. Follow the machine manufacturer and tooling manufacturer feeds-and-speeds recommendations for the workpiece material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2812 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 9\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 7.14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.642 inches (143.31 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.319 inches (84.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.301 inches (58.45 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: 0.051 inches (1.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.126 inches (54.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 8xD\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\u003eShank Type\u003c\/strong\u003e: Cylindrical\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\u003eTool Material\u003c\/strong\u003e: Solid 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MVS\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: 0.15 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: 663226\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51716544364850,"sku":"663226","price":346.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c379bcb8d08cb8569efb7441d13f2935_73c457e8-964b-45a0-9e31-48b215d26f47.jpg?v=1788527579","url":"https:\/\/voomisupply.com\/products\/mitsubishi-663226-extra-length-carbide-drill-bit-0-2812-in","provider":"Voomi Supply","version":"1.0","type":"link"}
