With a 5\/16 inch cutting diameter and four flutes, it delivers efficient material removal and a smooth surface finish. The AlTiN coating provides thermal resistance and extended tool life in ferrous and exotic alloy applications. A 30-degree helix angle balances chip evacuation with cutting force, and the centercutting geometry allows plunge entry directly into the workpiece. The reduced shank design — 1\/4 inch versus the 5\/16 inch cutting diameter — provides clearance in tighter setups without sacrificing rigidity at short overhangs.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills in tool-and-die, aerospace, and general precision machining shops. The single-end configuration with right-hand cut and right-hand flute is standard for conventional and climb milling on vertical machining centers. The 15\/32 inch length of cut accommodates shallow-to-moderate pocket depths. At 4 inches overall length, it fits standard tool holders without requiring extended-reach adapters in most setups. Machinists working aluminum, hardened steel, stainless, and titanium alloys will find the AlTiN finish and geometry well matched to those materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16 inch cutting diameter with 15\/32 inch length of cut for shallow-to-mid-depth pocketing and slotting\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish provides high-temperature oxidation resistance and extends tool life in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances chip evacuation with lateral cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eReduced 1\/4 inch shank allows use in smaller collets and provides clearance in confined workholding setups\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 accepting a 1\/4 inch collet or end mill holder.

Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing the tool. Seat the shank fully in the collet or end mill holder and torque the retention hardware to the toolholder manufacturer's specification. Confirm runout with a dial indicator before cutting, as excessive runout accelerates edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 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: 15\/32 inch (0.4690 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Reduced\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 943220-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51748000039218,"sku":"943220-C3","price":225.94,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8a5e745aa5ba7fe5bb98ac386c683d4_394216d2-3a49-480f-80e1-c65f21994fe6.jpg?v=1788887886","url":"https:\/\/voomisupply.com\/products\/harvey-tool-943220-c3-square-end-mill-5-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
