WIDIA HANITA

WIDIA HANITA end mills in the 3G Electric catalog are available with AlTiN (aluminum titanium nitride) or TiAlN (titanium aluminum nitride) coatings. AlTiN is typically used on fast-cutting end mills for stainless steel and super alloys, offering high oxidation resistance at elevated temperatures. TiAlN is applied to general-purpose end mills for steel and cast iron, providing a balance of hardness and lubricity. Both coatings are applied via PVD (physical vapor deposition) and are designed to reduce built-up edge and extend tool life in dry or mist-cooled machining.

General-purpose WIDIA HANITA end mills are designed for a broad range of materials and machining conditions, with standard geometries and coatings like TiAlN. They are suitable for routine milling operations where tool versatility is prioritized. Fast-cutting end mills are optimized for higher material removal rates in specific workpiece groups, such as stainless steels or super alloys. They feature specialized flute geometries and coatings like AlTiN to handle increased cutting speeds and temperatures. The fast-cutting variants typically have higher flute counts (e.g., 5 flutes) to improve chip thinning and surface finish at elevated feeds.

Yes, 3G Electric stocks WIDIA HANITA end mills in both fractional inch and metric diameters. Inch sizes include diameters such as 5/16", 1/2", and 9/16", with lengths of cut and overall lengths specified in inches. Metric sizes include diameters such as 8 mm, 10 mm, and 20 mm, with lengths of cut and overall lengths in millimeters. This dual-system availability allows procurement specialists to select tools that match machine tool specifications without unit conversion, supporting global manufacturing operations.

WIDIA HANITA end mills in the 3G Electric catalog are categorized by workpiece material groups. Specific variants are designed for stainless steels and super alloys (e.g., SKU 430F81), while others are intended for steels and cast irons (e.g., SKU 48KP66). General-purpose end mills cover a wider range of materials, including carbon steels, alloy steels, and non-ferrous metals. The tool geometry, coating, and flute count are tailored to each material group to optimize chip evacuation, heat management, and tool life. Buyers should match the end mill's designated material group to their workpiece for best performance.

WIDIA HANITA end mills in the 3G Electric inventory are offered with 2, 3, 4, or 5 flutes. Two-flute end mills are typically used for slotting and roughing in softer materials, providing good chip clearance. Three-flute designs balance chip evacuation and rigidity for general-purpose milling. Four-flute end mills are common for finishing operations in steels and cast irons, offering improved surface finish. Five-flute end mills are used in fast-cutting applications for stainless steels and super alloys, where higher feed rates and reduced vibration are required. The flute count is specified in the product SKU and manufacturer part number.

The length of cut (LOC) for WIDIA HANITA end mills in the 3G Electric catalog ranges from 16 mm to 75 mm in metric sizes and from 1/2" to 2-1/4" in inch sizes. For example, a 10 mm diameter end mill may have a 22 mm LOC, while a 1/2" diameter end mill can have a 1" LOC. The LOC is selected based on the depth of cut required for the application. Shorter LOCs provide greater rigidity for precision work, while longer LOCs allow deeper cuts in pocketing or profiling operations. Overall length (OAL) ranges from 2" to 5" for inch tools and up to 76 mm for metric tools.
