Accupro 12180596 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The ACCUPRO 12180596 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 3/8-inch diameter with a 0.03-inch corner radius, a 5/8-inch length of cut, and a 2-inch overall length. The cutting geometry is coated with AlTiN (aluminum titanium nitride) for extended tool life under high heat and abrasion. Manufactured from micrograin solid carbide, this single-end, centercutting tool is engineered for right-hand cutting and right-hand flute direction. It is suited for use by machinists and tooling professionals in production and job-shop environments.

This end mill is well suited for contour milling, profiling, and finishing operations where a controlled corner radius is required to reduce stress concentrations in part geometry. The 4-flute configuration and 40-degree helix angle support efficient chip evacuation and smooth surface finishes on ferrous and non-ferrous materials. Variable index flute spacing helps reduce chatter during aggressive cuts. The 3/8-inch shank diameter matches the 3/8-inch mill diameter for straightforward setup in standard collet and end mill holders.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating extends tool life in high-temperature cutting environments
• 0.03-inch corner radius reduces edge chipping and stress risers in finished parts
• 4-flute, 40-degree helix design promotes efficient chip evacuation and surface finish
• Variable index flute spacing reduces chatter and vibration
• Centercutting capability allows plunge entry without a pre-drilled hole

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 3/8-inch collet chucks, end mill holders, and hydraulic toolholders used in CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Verify collet or holder bore size matches the 3/8-inch shank diameter before tightening. Follow tool manufacturer torque guidelines for the specific holder type in use.
