Micro 100 CRE-250-090X Corner Rounding End Mill 1/4 in

Product Description

The MICRO 100 CRE-250-090X is a double-ended, solid carbide corner rounding end mill designed for precision edge-finishing operations in metalworking and machining environments. It features a 0.09 mm corner radius, a 0.25 inch mill diameter, and a 0.25 inch shank diameter, making it a compact tool suited for tight-tolerance work. The AlTiN coating improves heat resistance and extends tool life in hardened materials and high-speed cutting applications. With three right-hand flutes and right-hand cutting direction, this end mill delivers smooth chip evacuation and consistent finish quality. Machinists and tool-and-die professionals install this tool in CNC machining centers and manual mills.

This corner rounding end mill is used to produce uniform, burr-free rounded edges on metal workpieces. The double-ended design provides two usable cutting ends per tool, extending the service interval between replacements. With a tip diameter of 0.06 inch and a 0.09 mm radius, it is well suited for fine edge-breaking and corner-profiling passes on ferrous and non-ferrous materials. It fits standard 1/4 inch collets and tool holders commonly found in production and job-shop environments.

Key Features

• Double-ended design provides two cutting ends per tool for extended service life
• AlTiN coating enhances heat and wear resistance in high-speed and hardened-material applications
• Solid carbide construction delivers rigidity and dimensional stability under load
• 0.09 mm corner radius produces precise, consistent rounded edges
• Three right-hand flutes promote efficient chip evacuation and smooth surface finish
• Right-hand cutting direction compatible with standard CNC spindle rotation

Compatibility

Designed for use in standard 1/4 inch collet chucks and end mill holders on CNC machining centers and manual milling machines accepting 1/4 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or tool holder to the recommended engagement depth per the holder manufacturer guidelines. Verify cutting direction and spindle rotation are matched before initiating a cut.
