It runs a 0.050-inch cutting diameter with a 0.15-inch length of cut, making it well suited for micro-scale slotting, profiling, and pocketing operations. The 4-flute geometry with a 30-degree helix angle promotes efficient chip evacuation and stable tool engagement. An AlTiN coating adds heat resistance and extends tool life in harder workpiece materials. The 1\/8-inch shank fits standard collets and tool holders common in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use on CNC machining centers, high-speed mills, and toolroom equipment where small-diameter cutting tools are required. It suits work in steel, stainless steel, cast iron, and high-temp alloys where the AlTiN coating provides thermal protection. The centercutting design allows plunge entry, giving the operator flexibility for ramping and helical interpolation in die, mold, and precision component work. Right-hand cut and right-hand flute orientation are standard for conventional spindle direction.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.050-inch cutting diameter for micro-feature and small-slot applications\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix angle for smooth chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports plunge, ramp, and helical entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement solid carbide square end mill for use in 1\/8-inch collets and tool holders on CNC machining centers and manual mills requiring 3\/64-inch diameter square-end cutting tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before inserting or removing tooling. Seat the 1\/8-inch shank fully into the collet and torque the nut to the collet manufacturer specification. At this diameter, tool runout is critical — check TIR with a dial indicator before cutting to prevent premature breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.050 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: 0.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: 73050-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51750572687666,"sku":"73050-C3","price":46.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10f7065b7efd5c74dbe66d592f87ce4f.jpg?v=1788916860","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73050-c3-square-end-mill-3-64-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
