With a 3\/8-inch cutting diameter, a 1-inch length of cut, and a 30-degree helix angle, this tool delivers clean, accurate results across a range of materials. The amorphous diamond coating reduces friction and extends tool life by improving surface hardness and wear resistance. At 2.5 inches overall length with a 3\/8-inch shank diameter and 4 flutes, this end mill is suited for moderate-depth slotting, profiling, and pocketing. Licensed machinists and CNC programmers will find it ready to run right-hand cut with right-hand flute geometry.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in job shop and production environments for milling ferrous and non-ferrous metals, plastics, and composites. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, making it flexible for both roughing and finishing passes. A length-of-cut range of 1.0 to 1.25 inches accommodates typical workpiece depths in vertical machining center setups. It is a single-end tool, so all cutting life is concentrated in the one cutting end.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and thermal resistance at high feed rates\u003c\/li\u003e\n  \u003cli\u003eAmorphous diamond coating for improved wear resistance and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances chip evacuation and cutting force across flute length\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry supports direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard CNC spindle operation\u003c\/li\u003e\n  \u003cli\u003e4 flutes for improved finish quality on profiling and finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in CNC machining centers and manual mills with a 3\/8-inch collet or end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank fully in a properly sized collet or end mill holder, ensuring adequate engagement depth to prevent pullout under cutting load. Verify spindle runout is within acceptable tolerance before engaging the workpiece. Always follow machine manufacturer guidelines and applicable shop safety procedures when installing or changing cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 1.0000 to 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Amorphous Diamond\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: 15224-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51747423486258,"sku":"15224-C4","price":103.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f3057ff2465a20292d99d6436357341.jpg?v=1788879893","url":"https:\/\/voomisupply.com\/products\/harvey-tool-15224-c4-square-end-mill-3-8-inch-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
