With a 0.5 mm mill diameter and a 0.70 mm length of cut, this micro end mill is built for fine-detail work where accuracy at small scales is critical. The AlTiN coating provides thermal resistance and hardness at the cutting edge, extending tool life in abrasive and high-heat conditions. A 30-degree helix angle promotes efficient chip evacuation while maintaining edge stability. This tool is installed by machinists and tool-and-die professionals working with CNC machining centers and high-precision milling setups.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, cast iron, and hardened materials, corresponding to ISO material codes P, K, and H. The extended reach design and 6 mm straight shank make it compatible with standard collet systems used in CNC vertical and horizontal machining centers. It is a single-end, right-hand cutting tool with right-hand flute direction, making it appropriate for conventional CNC climb and conventional milling passes on small-feature geometries such as slots, pockets, and contours in tooling and die work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.5 mm mill diameter for micro and fine-detail milling operations\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for enhanced heat resistance and tool life on ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction in material grade KCPM15 for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth cutting action and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 6 mm straight shank for compatibility with standard collet holders\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, cast iron, and hardened materials (ISO P, K, H).

Seat the straight shank fully and evenly in a clean, undamaged collet to prevent runout that could break this micro-diameter tool. Confirm runout with a dial indicator before beginning a cut. Handle micro end mills with care — the 0.5 mm cutting diameter is susceptible to breakage from improper clamping, excessive feed rates, or side loading beyond the tool's rated parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 mm (0.0197 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.70 mm (0.0276 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60 mm (2.3622 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eMaterial Grade\u003c\/strong\u003e: KCPM15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: F2AH-WSM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.12 inches L x 0.52 inches H x 0.48 inches W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6433259\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754529882418,"sku":"6433259","price":125.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4e8453e20ffd62970422b4320e50e1e.jpg?v=1788946345","url":"https:\/\/voomisupply.com\/products\/kennametal-6433259-square-end-mill-0-5mm-2-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
