It carries a 3\/16 inch cutting diameter with a 9\/16 inch length of cut and a 2-1\/2 inch overall length. The AlTiN (aluminum titanium nitride) coating provides thermal resistance and extended tool life at elevated cutting speeds. A 30-degree helix angle promotes chip evacuation and reduces cutting forces. Centercutting geometry allows this tool to plunge directly into the workpiece, expanding its range of applications. Machinists and tool-and-die professionals specify this end mill for finishing and semi-finishing passes requiring tight tolerances and clean edge geometry.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills in job shop, production, and toolroom environments. Its 3\/16 inch shank diameter matches the cutting diameter for straightforward collet chuck setup. The 1-1\/2 inch reach length supports work in moderate-depth pockets and slots without excessive tool deflection. Right-hand cut and right-hand flute configuration is standard for conventional spindle-forward machining. It is a single-end tool, intended for replacement rather than regrinding once the cutting edge is worn.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating extends tool life in high-heat, high-speed cutting applications\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eExtended reach of 1-1\/2 inches supports pocket and slot milling at depth\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle-forward operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill compatible with standard 3\/16 inch collet chucks and end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with toolholder torque requirements and runout specifications. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended minimum grip length to prevent pullout under cutting loads. Verify runout with a dial indicator before commencing production cuts, as excessive runout will accelerate edge wear and degrade surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5620 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 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: 30 degrees\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\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 972312-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51735920312626,"sku":"972312-C3","price":90.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e92c096bc6ef0f75423e38273f3a3bd_552ddb25-c154-44de-8ce9-8b4e02ea7397.jpg?v=1788774910","url":"https:\/\/voomisupply.com\/products\/harvey-tool-972312-c3-square-end-mill-3-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
