Accupro 12180384 Corner Rounding End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 12180384 is a double-end, solid carbide corner rounding end mill designed to produce smooth, consistent radius profiles on workpiece edges. With a 0.05 inch radius and a 0.25 inch mill diameter, it generates a precise convex edge break in a single pass. The 4-flute geometry supports efficient chip evacuation and surface finish quality on ferrous and non-ferrous materials. The bright, uncoated finish makes it suitable for applications where coating interaction with the workpiece material is a concern. Machinists and tool-and-die professionals use this end mill on CNC machining centers and manual mills where edge-rounding operations are required.

This end mill is suited for edge profiling operations on a range of materials in job shop, production, and tooling environments. The double-end configuration provides two usable cutting ends, extending tool life between changes. The 1/4 inch shank diameter fits standard collets and end mill holders common to vertical machining centers and CNC routers. It is appropriate for light-to-moderate finishing passes where a controlled 0.05 inch radius is specified by drawing or inspection requirement.

Key Features

• 0.05 inch corner radius delivers a precise, repeatable edge profile
• Double-end design provides two cutting ends per tool
• 4-flute configuration supports smooth surface finish and chip clearance
• Solid carbide construction offers rigidity and wear resistance over high-speed steel alternatives
• Bright, uncoated finish suitable for dry cutting or use with standard cutting fluids
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed for use in standard 1/4 inch collets and end mill holders on CNC machining centers, vertical mills, and CNC routers requiring a 0.05 inch corner rounding profile.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's runout and tool-holding specifications. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Verify collet size matches the 1/4 inch shank diameter before tightening. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material.
