Built from solid carbide with a physical vapor deposition (PVD) AlTiN coating, this single-end tool delivers hardness and thermal resistance suited for cutting steel, stainless steel, and cast iron. The 0.50 mm (0.0200 inch) mill diameter pairs with a 0.0100-inch nose radius and a 30-degree right-hand spiral helix to produce clean, accurate profiles. A stub flute configuration keeps the cutting length at 0.0300 inches, while the extended reach design provides a 0.1600-inch reach length for accessing recessed features.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for high-precision machining environments where miniature tooling is required. The long-reach, stub-flute geometry makes it well suited for die and mold work, medical component manufacturing, and aerospace part finishing where fine detail and dimensional control are critical. It handles both roughing and finishing passes in ferrous and hard materials. The 1\/8-inch straight cylindrical shank and 2.5-inch overall length allow it to seat in standard collet chucks without special toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.50 mm (0.0200 inch) ball nose diameter with 0.0100-inch nose radius for fine detail work\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides thermal resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e3-flute, 30-degree right-hand spiral helix balances chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eExtended long-reach design with 0.1600-inch reach length for deep or recessed features\u003c\/li\u003e\n  \u003cli\u003eStub flute length (0.0300 inches LOC) reduces deflection and improves rigidity at small diameters\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction supports higher feed rates and tighter tolerances than HSS alternatives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with standard 1\/8-inch collet or toolholder systems.

Confirm runout at the tool tip before cutting, as runout errors are proportionally larger relative to the 0.50 mm diameter. Ensure the spindle and toolholder are clean and free of debris before seating. Do not exceed the tool manufacturer's recommended speeds and feeds for the specific workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.50 mm (0.0200 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.1300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.1600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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 (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 34220-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51751498645810,"sku":"34220-C3","price":108.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/413fedd45fa13c45d2c5156b021f0900_dc1bce74-7129-4319-84e9-c1f2809d5fb9.jpg?v=1788923632","url":"https:\/\/voomisupply.com\/products\/harvey-tool-34220-c3-ball-end-mill-0-50mm-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
