Built to MVS Series specifications, it features a 1\/4 inch (0.2500 inch) cutting diameter, a 140-degree drill point angle with X-Thinning geometry, and a TiAlN coating that extends tool life when cutting through hard and abrasive materials. The helical flute design promotes chip evacuation, while the coolant-through construction allows internal coolant delivery to the cutting zone. This bit is intended for use by machinists, toolroom technicians, and CNC operators working with precision drilling operations in metalworking environments.\u003c\/p\u003e\u003cp\u003eThe 663197 is suited for cross hole drilling, stack drilling, and standard through-hole drilling applications where extended reach is required beyond what a jobber-length bit can provide. Its 8xD flute-to-diameter ratio supports deeper bore depths with a maximum drilling depth of 2.0470 inches. The cylindrical shank measures 0.315 inches in diameter and 2.0870 inches in length, making it compatible with standard collet chucks and tool holders used in CNC machining centers and drill presses. Primary workpiece materials include steel and hardened steel, with secondary compatibility covering stainless steel, superalloys, titanium, cast iron, aluminum, aluminum alloy, brass, bronze, high strength bronze, carbon steel, tempered steel, structural steel, and copper.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN coating for extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e140-degree X-Thinned drill point reduces thrust and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers internal coolant directly to the cutting edge\u003c\/li\u003e\n\u003cli\u003eHelical flute geometry promotes efficient chip evacuation in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003e8xD flute ratio supports drilling depths up to 2.0470 inches\u003c\/li\u003e\n\u003cli\u003eCylindrical shank fits standard collet chucks and drill press tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with cross hole, stack drilling, and standard drilling operations across a broad range of workpiece materials including steel, stainless steel, superalloys, titanium, cast iron, aluminum, brass, bronze, copper, and carbon steel.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the bit from the tool holder. Verify collet or chuck runout is within acceptable tolerance before use to prevent premature tool wear or breakage. Activate coolant supply before engaging the cut when using the coolant-through feature.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 6.35 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (Decimal Inch)\u003c\/strong\u003e: 5.1640 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 131.17 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (Decimal Inch)\u003c\/strong\u003e: 2.8820 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 73.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth (Decimal Inch)\u003c\/strong\u003e: 2.0470 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth (mm)\u003c\/strong\u003e: 51.99 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 8.0000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length (Decimal Inch)\u003c\/strong\u003e: 2.0870 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length (mm)\u003c\/strong\u003e: 53.010 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 (Decimal Inch)\u003c\/strong\u003e: 0.0450 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length (mm)\u003c\/strong\u003e: 1.14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-Thinning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\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\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: 0.13 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: 663197\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51692765348146,"sku":"663197","price":332.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c379bcb8d08cb8569efb7441d13f2935_473ff560-eee0-43fc-9654-0909e1031788.jpg?v=1788302521","url":"https:\/\/voomisupply.com\/products\/mitsubishi-663197-carbide-extra-length-drill-bit-1-4-in-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
