Micro 100 CRE-375-156 Corner Rounding End Mill 3/8 in

Product Description

The MICRO 100 CRE-375-156 is a solid carbide corner rounding end mill designed to produce smooth, consistent radius profiles on workpiece edges. With a 5/32-inch corner radius and a 3/8-inch mill diameter, this tool removes material along curved edge geometries in a single controlled pass. The double-ended design effectively doubles tool life by providing two usable cutting ends before the tool is retired. Three right-hand flutes with a bright, uncoated finish make this cutter well-suited for general-purpose edge rounding in a wide range of materials. It is typically installed by machinists and toolmakers running CNC mills or manual milling machines in production or job-shop environments.

This end mill is intended for edge-breaking and radius-forming operations on metal workpieces where a precise, repeatable corner profile is required. The 3/8-inch shank diameter fits standard collets and end mill holders common to most vertical milling centers. The small tip diameter of 0.060 inches allows the tool to engage tight corner geometries without interference. This tool is appropriate for use in both low-volume prototype work and higher-volume production runs where consistent edge geometry must be maintained across multiple parts.

Key Features

• 5/32-inch corner radius for precise, repeatable edge rounding
• Double-ended configuration provides two cutting ends per tool
• Solid carbide construction for rigidity and wear resistance
• 3 right-hand flutes with right-hand cutting direction
• Bright, uncoated finish suitable for general-purpose milling applications
• 0.060-inch tip diameter allows engagement in tight corner geometries

Compatibility

Designed for use in standard 3/8-inch collets and end mill holders on CNC vertical machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling setup procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the collet or holder and torque to the holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
