With a 0.0300-inch cutting diameter and a 0.045-inch length of cut, this tool targets tight-tolerance slots, pockets, and profiling passes in hardened steels and exotic alloys where rigidity and sharp edge retention are critical. The AlTiN coating improves heat resistance and extends tool life in dry or near-dry cutting conditions. A 30-degree right-hand helix promotes efficient chip evacuation across the three flutes. Licensed machinists and CNC tooling specialists rely on tools in this class for micro-milling operations in tool-and-die, aerospace, and medical device work.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits small-diameter applications requiring extended reach, with a 0.25-inch reach length beyond the shank. The 0.125-inch shank diameter mounts directly into standard 1\/8-inch collets, ER collet chucks, or precision hydraulic holders. It is centercutting, allowing plunge entry as well as peripheral and slot milling. The 2.5-inch overall length provides clearance for deeper workpiece features without custom tooling setups. Typical use cases include finish milling of hardened mold cavities, engraving detail passes, and precision contouring in CNC machining centers and high-speed spindle platforms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0300-inch cutting diameter with 0.045-inch length of cut for micro-precision work\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating enhances heat and wear resistance in hardened and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry with 30-degree right-hand helix for effective chip clearing\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eExtended reach configuration with 0.25-inch reach length for deeper feature access\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction maintains rigidity at small diameters under high-speed conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and high-speed milling spindles accepting 1\/8-inch shank tooling via ER collet or precision hydraulic chuck systems.

Always confirm spindle runout and collet condition before seating a small-diameter end mill, as excessive runout accelerates tool breakage at this diameter range. Ensure the machine spindle is fully stopped and locked before tool changes. Follow shop-standard torque procedures for collet nut tightening and verify tool stick-out matches programmed values before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.045 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\u003eReach Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\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\u003eExtended Reach\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 34630-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51727369044274,"sku":"34630-C3","price":78.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48693790ec4e97f05d5a09a1389fd32c.jpg?v=1788676860","url":"https:\/\/voomisupply.com\/products\/harvey-tool-34630-c3-square-end-mill-0-030-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
