Micro 100 CRE-125-031X Corner Rounding End Mill

Product Description

The MICRO 100 CRE-125-031X is a double-ended, solid carbide corner rounding end mill designed for precise edge-breaking and radius profiling on metal workpieces. With a 1/32 inch corner radius and a 1/8 inch mill diameter, this tool produces consistent, repeatable radiused edges in a single pass. The 3-flute geometry balances chip evacuation with surface finish quality. An AlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials. Machinists and toolmakers running CNC mills or manual machines install this type of tool for finishing operations where sharp corners must be eliminated to spec.

This end mill is suited for precision machining applications in job shops, mold and die work, aerospace component finishing, and general metalworking. The double-ended design effectively doubles the usable life of a single tool, making it a practical choice for shops running moderate production volumes. The 1/8 inch shank fits standard ER collet chucks and small-bore toolholders commonly found on vertical machining centers and CNC router tables configured for metal. The right-hand cut and right-hand flute direction are standard for conventional CNC milling setups.

Key Features

• Double-ended design provides two usable cutting ends per tool
• 1/32 inch corner radius for precise, consistent edge rounding
• AlTiN coating for improved heat resistance and extended tool life in ferrous materials
• Solid carbide construction delivers rigidity and wear resistance
• 3-flute geometry balances chip clearance and surface finish
• Right-hand cut and right-hand flute direction for standard CNC milling use

Compatibility

Designed for use with standard 1/8 inch ER collet chucks and small-bore toolholders on CNC vertical machining centers and manual mills. Fits tooling systems accepting a 1/8 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists using appropriate collet chucks torqued per the toolholder manufacturer specifications. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify runout with a dial indicator after seating the shank to prevent premature edge wear. Follow shop-standard feeds and speeds for solid carbide end mills in the specific workpiece material.
