Built to MVS Series specifications, it features a TiAlN coating and an X-Thinned web with X-Thinning point geometry that reduces thrust and improves chip evacuation. The 140-degree drill point angle is suited for hard and difficult-to-machine materials. With a 1.327-inch flute length and a 3.510-inch overall length, this bit provides the reach needed for deeper bore access while maintaining rigidity through its parallel web configuration. Coolant-through capability supports extended tool life in high-cycle operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in cross hole drilling, standard drilling, and stack drilling operations. It is designed for right-hand cutting with a right-hand helical flute and a cylindrical shank. Primary workpiece material is steel, with secondary suitability for stainless steel, superalloys, titanium, structural steel, tempered steel, iron, high-strength bronze, hardened steel, copper, cast iron, carbon steel, bronze, brass, aluminum, and aluminum alloys. Typical users include machinists, tool-and-die tradespeople, and maintenance technicians working in metal fabrication or production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide construction with TiAlN coating for heat and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle optimized for hard and multi-material workpieces\u003c\/li\u003e\n  \u003cli\u003eX-Thinning point geometry reduces cutting force and improves centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip clearing and thermal management in deep-hole operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand helical flute with parallel web for consistent chip flow and structural stability\u003c\/li\u003e\n  \u003cli\u003e3xD flute-to-diameter ratio provides extended reach while limiting deflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for machining operations requiring a 0.25-inch diameter carbide extra length bit in the MVS Series configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit should be installed by a qualified machinist or maintenance technician familiar with CNC or manual drilling equipment. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet specifications match the 0.315-inch shank diameter before securing the bit. Enable coolant flow before engaging the cut when using coolant-through setups to prevent thermal shock to the carbide tip.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.510 inches (89.15 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.327 inches (33.71 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8.0 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.087 inches (53.01 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.797 inches (20.24 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.045 inches (1.14 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\u003eCutting Direction\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\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\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\u003eTool Application\u003c\/strong\u003e: Cross Hole, Drilling, Stack Drilling\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: 0.11 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: 662653\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51697596301618,"sku":"662653","price":181.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c379bcb8d08cb8569efb7441d13f2935_b57f9d95-24b7-4d34-a6ea-71a8649b8424.jpg?v=1788353221","url":"https:\/\/voomisupply.com\/products\/mitsubishi-662653-extra-length-carbide-drill-bit-0-25in","provider":"Voomi Supply","version":"1.0","type":"link"}
