Iscar 5620529 Corner Chamfer End Mill 2.5mm 3-flute Carbide

Product Description

The ISCAR 5620529 is a solid carbide corner chamfer end mill designed for precision metal removal in demanding machining environments. Built to the ECS-E-3 series standard, it features a 2.5 mm cutting diameter, a 45-degree chamfer angle, and a 38-degree medium helix. The AlTiN (PVD) coating provides thermal resistance and extended tool life when cutting hard or abrasive materials. With a 6 mm Weldon flat shank and an overall length of 57 mm, this tool is engineered for stability and reach in tight setups. It is a single-end, right-hand cut tool with center-cutting capability, making it suitable for both entry cuts and full-slot operations.

This end mill is intended for machining stainless steel, superalloys, and titanium — materials classified under ISO material codes M and S. Typical applications include shouldering, slotting, ramp-down milling, helical interpolation, drill milling, and plunging and recessing operations. The extended reach design, with an 8 mm reach length and a reduced 2.40 mm neck diameter, allows access to features in deep pockets or stepped workpieces. It is suited for use on CNC machining centers in both production and job-shop environments where close-tolerance work on difficult materials is routine.

Key Features

• 45-degree chamfer angle for consistent edge preparation and corner chamfering
• AlTiN PVD coating rated for high-temperature cutting in stainless steel, superalloys, and titanium
• 38-degree medium helix with 3 helical flutes for balanced chip evacuation and surface finish
• Center-cutting geometry supports plunging, ramp-down, and helical interpolation without a pre-drilled hole
• Extended reach with 8 mm reach length and 2.40 mm neck diameter for deep-pocket access
• Weldon flat shank in 6 mm diameter for secure holder engagement and reduced pullout risk
• Supports roughing and finishing in a single tool, minimizing tool changes in multi-operation setups

Compatibility

Designed for use in standard 6 mm Weldon flat end mill holders on CNC machining centers. Primary workpiece materials are stainless steel, superalloys, and titanium (ISO material codes M and S). Manufacturer catalog reference: ECS025E03-3W06-57.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the Weldon flat shank fully into the holder and torque the set screw to the holder manufacturer specification — do not rely on finger-tight engagement. Verify runout at the cutting diameter before first use, as excessive runout will accelerate wear and compromise tolerance on hard-material workpieces.
