It features a 0.0450-inch cutting diameter with a 0.225-inch length of cut, making it well-suited for fine detail work and tight-tolerance slot and profile milling. The tool is ground from solid carbide for rigidity and wear resistance. A 30-degree right-hand helix and right-hand cut geometry promote efficient chip evacuation and smooth cutting action. The bright, uncoated finish is standard for general-purpose carbide tooling. This end mill is installed and operated by machinists and tool-and-die professionals on CNC and manual milling equipment.\u003c\/p\u003e\u003cp\u003eThis end mill is used in applications requiring small-diameter, high-precision cuts. The 0.0450-inch diameter makes it appropriate for micro-milling, engraving, fine slot cutting, and detail work on small components. The 0.125-inch shank diameter fits standard 1\/8-inch collets and tool holders common on CNC machining centers, mini mills, and precision benchtop equipment. The 2.5-inch overall length provides adequate clearance for most setups without sacrificing rigidity at this diameter. It is a single-end tool sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0450-inch cutting diameter for precision micro-milling and fine detail work\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life compared to HSS\u003c\/li\u003e\n\u003cli\u003e3-flute geometry balances chip load and surface finish in small-diameter applications\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose non-ferrous and ferrous milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/8-inch collets and tool holders on CNC machining centers and manual milling equipment accepting square end mills with a 0.125-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the collet and tool holder are clean and free of chips before seating the shank. Verify runout with a dial indicator after clamping, as even minor runout is critical at this cutting diameter. Do not exceed the recommended depth of cut for small-diameter carbide tooling, as solid carbide is brittle and susceptible to breakage under side load at this size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0450 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.225 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: Bright\/Uncoated\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\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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12745\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51730092327218,"sku":"12745","price":59.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8842c115dffb99c3f73becd1f95e76e1_88e27ba2-a4ff-4599-a39b-3b220c7a2935.jpg?v=1788711648","url":"https:\/\/voomisupply.com\/products\/harvey-tool-12745-square-end-mill-0-045-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
