It features a 1\/8 inch cutting diameter with a 1\/4 inch length of cut and a 38-degree helix angle that promotes efficient chip evacuation and reduces cutting forces. The four-flute, right-hand cutting configuration is paired with a TiAlN-LT coating, which improves thermal resistance and extends tool life when cutting at elevated temperatures. With a 1-1\/2 inch overall length and a straight cylindrical shank, this end mill is suited for CNC machining centers and manual mills where compact tooling is required.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials, making it a practical choice for mold and die work, aerospace component machining, and general precision part production. The Series 4V05 designation places it within a purpose-built line for difficult-to-machine alloys and high-temperature materials. It is centercutting, allowing direct plunge entry without a pre-drilled pilot hole. Typical users include CNC machinists and tool-and-die professionals working in job shops or production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8 inch cutting diameter with 1\/4 inch length of cut for small-feature and slot milling\u003c\/li\u003e\n\u003cli\u003eTiAlN-LT coating for improved heat resistance and tool life in high-temperature alloy cutting\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eFour right-hand flutes with helical flute geometry for smooth surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 1\/8 inch diameter for standard collet compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials.

Ensure the machine spindle is fully powered down and locked out before changing tooling. Secure the shank in a properly sized collet or end mill holder to the recommended clamping torque specified by the toolholder manufacturer. Verify runout before initiating a cut, as excessive runout will accelerate wear and reduce dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/4 inch (0.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN-LT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\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: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 4V05\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: High Temperature Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 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: WIDIA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2870202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67907983966514,"sku":"2870202","price":60.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7aa49b01029403705f99cfb9a82018e_f66b4433-9aeb-41c1-9c2b-a1ef25309765.jpg?v=1791182100","url":"https:\/\/voomisupply.com\/products\/widia-2870202-square-end-mill-1-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
