Seco 03205025 Ball End Mill 0.0787 in 2 Flute Carbide Hxt

Product Description

The SECO 03205025 is a solid carbide ball end mill designed for precision milling in hard and difficult-to-machine materials. Part of the JMB112 series, this single-end tool features a 2 mm (0.0787 inches) mill diameter with a 1 mm nose radius and a 28-degree medium helix angle. The HXT PVD coating provides thermal and wear resistance suited for demanding cutting conditions. With a straight-cylindrical 6 mm shank and a 50 mm overall length, this extended-reach tool is built for deep-cavity and contour milling where clearance is critical. The micrograin carbide substrate supports both roughing and finishing passes in a single setup.

This end mill is used in CNC machining centers for milling hard materials such as hardened steels, tool steels, and similar high-hardness workpiece materials. The extended reach configuration and 6 mm reach length make it well suited for die and mold work, fine-feature machining, and tight-tolerance profiling. It is typically installed and run by machinists and CNC operators working in tool rooms, job shops, and precision manufacturing environments.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention in hard materials
• HXT PVD coating for thermal resistance and extended tool life
• Extended reach design with 6 mm reach length and 4 mm neck length for deep-cavity access
• 28-degree medium helix angle optimized for hard material removal
• Right-hand cut and right-hand helical flute geometry for standard CNC spindle use
• Suitable for both roughing and finishing operations in a single tool

Compatibility

Designed as an OEM-specification cutting tool in the SECO JMB112 series, intended for use in CNC milling machines with standard straight-bore tool holders accepting a 6 mm shank diameter.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC operators familiar with cutting tool setup and machine programming. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized collet or hydraulic chuck matched to the 6 mm shank diameter to achieve the manufacturer-specified TIR maximum of 0.01 mm. Verify runout at the tool tip before initiating a cut, particularly given the small 2 mm diameter and extended reach of this tool.
