Featuring a 0.5-inch cutting diameter and a 1.5-inch length of cut, this end mill is built to deliver consistent material removal in ferrous and non-ferrous metals. The W421 series design incorporates a variable helix angle of 37\/39 degrees, which reduces harmonic vibration and chatter during aggressive cuts. With four right-hand helical flutes and a centercutting geometry, this tool handles both peripheral and plunge milling. It is sized for use in standard 0.5-inch collets or Weldon flat shank holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for production and job-shop machining operations where surface finish and dimensional accuracy matter. The WU20PE carbide grade and variable helix construction make it appropriate for use on CNC machining centers and manual mills working steel, alloy steel, and similar workpiece materials. The Weldon flat shank provides positive drive and prevents pullout under high feed conditions. Typical users include CNC machinists, tool-and-die makers, and precision machine shop technicians working in both prototype and production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in WU20PE grade for wear resistance in steel and alloy applications\u003c\/li\u003e\n  \u003cli\u003eVariable helix design at 37\/39 degrees reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eFour right-hand helical flutes with centercutting capability for peripheral and plunge operations\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank prevents tool pullout in high-feed setups\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with regular length geometry for standard reach applications\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 27112803 for procurement system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 0.5-inch end mill holders, collet chucks, and Weldon flat-style set-screw tool holders.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the Weldon flat shank fully into the holder and torque the set screw to the holder manufacturer's specification. Verify runout with a dial indicator before initiating a cut, and confirm feed, speed, and depth-of-cut parameters match the workpiece material and machine capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 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: 37\/39 degrees (variable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: WU20PE\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\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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: W421\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.313 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: WIDIA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6945716\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67909768610098,"sku":"6945716","price":144.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8628d5a8be0915986f09efc696b0a0c0.jpg?v=1791191872","url":"https:\/\/voomisupply.com\/products\/widia-6945716-square-end-mill-0-5-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
