With a 0.12 inch cutting diameter and a 23\/64 inch (0.36 inch) length of cut, this end mill handles slotting, profiling, and peripheral milling in tight geometries. The 4-flute configuration provides a balance of chip evacuation and surface finish quality. A 30-degree helix angle promotes smooth cutting action and reduces vibration. The bright, uncoated finish makes it well suited for non-ferrous metals, plastics, and other materials where coating adhesion is not required. This tool is a single-end design and is installed by machinists and CNC programmers in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThe HARVEY TOOL 73120 fits applications where small-diameter, high-precision milling is required. Typical use cases include finish milling of aluminum, brass, copper, and engineered plastics, as well as detail work on molds, dies, and fixtures. The 1\/8 inch shank diameter makes it compatible with standard collets and tool holders sized for that bore. Right-hand cut and right-hand flute direction are standard for conventional CNC machining center setups. The 1.5 inch overall length keeps the tool rigid in the spindle, minimizing deflection at small diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n\u003cli\u003e4 flutes for improved surface finish and feed rate capability\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix for smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for non-ferrous metals and plastics\u003c\/li\u003e\n\u003cli\u003eSingle-end tool with 1\/8 inch shank for compatibility with standard collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/8 inch bore collets and tool holders on CNC machining centers and manual milling machines.

Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing tooling. Seat the shank fully into the collet and tighten to the tool holder manufacturer torque specification. Verify runout with a dial indicator before beginning a production run, as runout at small diameters has an outsized effect on tool life and surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 23\/64 inches (0.36 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\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inches (0.125 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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.01 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: 73120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51742221140274,"sku":"73120","price":34.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c96247132d19a5254664b32cd20791c_01bcce84-3ecc-4fae-835d-19c7a0ba09fa.jpg?v=1788835977","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73120-square-end-mill-0-12-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
