Built on the MVS Series platform, this bit features a TiAlN coating, a 140-degree drill point angle with X-Thinning geometry, and a helical right-hand flute configuration. The cutting diameter is 0.2500 inches (6.35 mm), the flute length is 5.9530 inches, and the overall length is 8.1560 inches, giving it a flute-to-diameter ratio of 20xD. Maximum drilling depth reaches 5.0470 inches. The cylindrical shank measures 0.315 inches in diameter and 2.0870 inches in length. This tool weighs 0.14 pounds and is sold individually.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for deep hole drilling, cross hole drilling, stack drilling, and standard through-hole operations in a wide range of workpiece materials. Its 20xD reach and parallel web configuration make it well matched to production environments where hole depth or stack thickness exceeds the capacity of standard-length drills. Rated for right-hand cutting, it is intended for use in CNC machining centers, drill presses, and similar powered spindle equipment operated by machinist and tooling professionals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2500 inch (6.35 mm) cutting diameter with 140-degree X-Thinned point for reduced thrust and clean entry\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and tool life in steel, stainless, and superalloy cutting\u003c\/li\u003e\n\u003cli\u003e20xD flute-to-diameter ratio and 5.0470 inch maximum drilling depth for deep hole and stack drilling\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery to extend tool life and clear chips at depth\u003c\/li\u003e\n\u003cli\u003eHelical right-hand flutes with parallel web configuration for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eCylindrical shank at 0.315 inches diameter for compatibility with standard collets and drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in applications involving steel, stainless steel, superalloys, titanium, structural steel, tempered steel, hardened steel, cast iron, carbon steel, bronze, high strength bronze, brass, copper, aluminum, and aluminum alloy workpiece materials.

Secure the cylindrical shank in a properly sized collet or drill chuck to the tool holder manufacturer's specified clamping method before operation. When using the coolant-through feature, confirm that coolant pressure and flow rate are within the machine tool and toolholder specifications. Do not exceed the 5.0470 inch maximum drilling depth rating for this tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.1560 inches (207.16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.9530 inches (151.21 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 5.0470 inches (128.19 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: 2.0870 inches (53.01 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0450 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\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: X-Thinning\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: 20xD\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 10544044\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51708056043826,"sku":"10544044","price":644.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c379bcb8d08cb8569efb7441d13f2935_011e382a-a7af-4bd8-b3b3-92fc1de17f9d.jpg?v=1788443679","url":"https:\/\/voomisupply.com\/products\/mitsubishi-10544044-carbide-extra-length-drill-bit-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
