Built to the AADE series standard, it features a 3\/8 inch cutting diameter, a 1-1\/2 inch length of cut, and a 3-flute spiral geometry with a 37-degree helix angle. The single-end, centercutting design allows plunge entry as well as peripheral and slot milling. This tool is supplied in an uncoated (bright) finish and manufactured from micrograin K600 carbide grade, offering the wear resistance and edge retention needed for demanding cuts. It is installed and used by machinists and tooling technicians in job shops, production environments, and maintenance machine rooms.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose milling operations in ferrous and non-ferrous materials where a sharp, uncoated carbide edge is preferred over coated alternatives. The right-hand cut and right-hand flute configuration make it compatible with standard vertical and horizontal milling machines, CNC machining centers, and manual knee mills. The 3\/8 inch shank diameter fits standard ER and side-lock collet systems commonly found in production toolholding setups. The 4 inch overall length provides reach for the majority of typical workpiece depths without excessive overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch cutting diameter with a 1-1\/2 inch length of cut for versatile slot and peripheral milling\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry with 37-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid carbide K600 micrograin grade delivers edge integrity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish suitable for applications where coating is not required or preferred\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute; no chipbreaker or variable helix for predictable performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style tooling solution for standard 3\/8 inch collet or side-lock toolholders on CNC machining centers and manual milling machines; verify spindle and toolholder compatibility before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and locked out before tool changes. Ensure the collet or toolholder bore is clean and free of chips before seating the shank to the recommended engagement depth. Follow machine manufacturer torque specifications for collet nut tightening. Confirm runout with a dial indicator after installation before initiating a cutting pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 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: 0.375 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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003eChipbreaker\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\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\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: K600 Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AADE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3658827\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750330433842,"sku":"3658827","price":195.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff3bdc3e2a40221e6c1a6941c16f74f4.jpg?v=1788914834","url":"https:\/\/voomisupply.com\/products\/kennametal-3658827-square-end-mill-3-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
