With a 0.5-inch mill diameter and a 1.625-inch length of cut, this single-end tool delivers the rigidity and edge retention needed for demanding ferrous-material applications. The Tplus coating provides wear resistance and heat dissipation, extending tool life in aggressive cutting conditions. A 35-degree helix angle promotes efficient chip evacuation and smooth cutting action. Licensed machinists and CNC programmers working in job shops, production facilities, and tool rooms will find this end mill suited to both roughing and finishing passes in difficult materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for milling steel, stainless steel, and cast iron in both roughing and finishing operations. The variable index design reduces harmonic vibration during cutting, making it appropriate for full-slot and side-milling applications where chatter is a concern. It fits standard 0.5-inch collets and tool holders commonly found in vertical machining centers and CNC mills. It is part of the Helical Solutions End Mills for Stainless and High Temp 4-Flute Square Variable Pitch series, targeting challenging workpiece materials where tool wear and deflection are primary concerns.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides superior hardness and wear resistance versus HSS tooling in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter during milling\u003c\/li\u003e\n  \u003cli\u003eTplus coating improves heat resistance and extends tool life in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e35-degree right-hand helical flutes promote efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eStraight shank at 0.5 inches fits standard collets and shrink-fit holders without modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with standard 0.5-inch collet or tool holder systems.

Inspect the shank and collet bore for chips or damage before seating the tool. Set appropriate feed rate and depth of cut for the specific workpiece material and machine rigidity before initiating a cut. Follow your facility's lockout and machine-guarding procedures whenever changing tooling in a CNC spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Tplus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.331 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 82273\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51735254237490,"sku":"82273","price":196.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bba5ed852652fec5dad28eea4c05df45_4a137aa5-6f02-484d-9ec5-645ebeef9f84.jpg?v=1788771022","url":"https:\/\/voomisupply.com\/products\/helical-solutions-82273-square-end-mill-0-5in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
