With a 0.03-inch mill diameter and a 3\/32-inch (0.09-inch) length of cut, this tool is built for fine-feature machining in hardened metals, stainless alloys, and other difficult-to-machine materials. The AlTiN coating provides thermal resistance and extended tool life at elevated cutting temperatures. Four right-hand flutes with a 30-degree helix angle deliver efficient chip evacuation and a clean finish. Licensed machinists, toolmakers, and CNC programmers rely on this end mill for tight-tolerance work in production and prototype environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for small-diameter slot milling, pocket milling, and contouring operations on CNC machining centers and manual mills. The 1\/8-inch shank diameter fits standard collets and end mill holders commonly found in vertical machining centers. The 1-1\/2-inch overall length and 0.27-inch reach length make it appropriate for shallow-to-moderate depth applications where rigidity and runout control are critical. It is center-cutting, allowing for direct plunge entry without pre-drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03-inch mill diameter for fine-feature and micro-milling applications\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-temperature resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e4 right-hand flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits standard collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement-style solid carbide end mill for CNC machining centers and manual mills equipped with 1\/8-inch collets or end mill holders.\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 powered down and locked out before changing tooling. Confirm collet size matches the 1\/8-inch shank diameter and that the tool is seated to the correct gauge length before tightening. Verify runout with a dial indicator before initiating a cut, particularly given the small diameter of this tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.09 inches (3\/32 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\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 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\u003eReach Length\u003c\/strong\u003e: 0.27 inches\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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: 76430-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51739504509234,"sku":"76430-C3","price":78.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2c782c0ff49635f1f10a64ca4138f74_1dd1bd63-ec6f-465c-814b-ae0226f21e78.jpg?v=1788815357","url":"https:\/\/voomisupply.com\/products\/harvey-tool-76430-c3-square-end-mill-0-03-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
