Kennametal 3524545 Corner Radius End Mill 6mm 5 Flute

Product Description

The KENNAMETAL 3524545 is a solid carbide corner radius end mill designed for high-performance milling in demanding industrial machining environments. It features a 6 mm cutting diameter, a 1.5 mm corner radius, and five flutes with a high-helix spiral configuration at a 38-degree helix angle. The cutting edge spans 13 mm, and the overall length is 63 mm. An AlTiN physical vapor deposition (PVD) coating provides thermal resistance and extended tool life when cutting abrasive or hard workpiece materials. The shank diameter is 6 mm with a Weldon flat for positive drive retention. This tool is intended for single-end use and is suited for both roughing and finishing operations.

The 3524545 is engineered for cutting steel, cast iron, superalloys, titanium, and hard materials. It belongs to the KENNAMETAL UDDE series, which is optimized for extended-reach applications. The neck diameter of 5.64 mm and an 18 mm reach length allow access to recessed features and stepped pockets without sacrificing rigidity. This end mill is a practical choice for tool and die shops, aerospace component machining, and general precision machining where corner radius geometry is required to reduce stress concentrations at part transitions.

Key Features

• AlTiN PVD coating for high heat resistance in steel, cast iron, superalloys, titanium, and hard materials
• 5-flute design supports higher feed rates compared to standard 4-flute geometry
• 1.5 mm corner radius reduces stress concentration and improves surface finish at part radii
• Extended-reach configuration with 18 mm reach length and reduced 5.64 mm neck diameter
• Weldon flat shank provides positive rotational drive in compatible toolholders
• Submicron carbide grade for wear resistance and edge integrity in difficult-to-machine alloys

Compatibility

Compatible with ER single angle standard collets and HC 1/2 through HC 1 1/4 hydraulic sleeves with metric bores. Designed as an OEM-specification solid carbide end mill for use in milling machines and machining centers capable of accepting a 6 mm Weldon flat shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Confirm the toolholder bore and clamping style match the 6 mm Weldon flat shank before seating the tool. Power down and lock out the spindle before changing tooling, in accordance with applicable machine safety procedures. Do not exceed the toolholder manufacturer's recommended clamping torque or overhang specifications.
