Harvey Tool 23232-C3 Undercut End Mill 0.5 in 4-flute Altin

Product Description

The HARVEY TOOL 23232-C3 is a solid carbide undercut end mill designed for machining operations that require relief cuts, undercuts, and slot profiles that standard end mills cannot reach. With a 0.5-inch mill diameter, a 270-degree wrap angle, and a 4-flute right-hand cutting geometry, this tool delivers aggressive material removal in a single-end configuration. The AlTiN coating provides elevated heat resistance and extended tool life in ferrous and hardened materials. The 0.427-inch length of cut (LOC) and 1.0-inch neck length allow access to deep features while maintaining rigidity through the solid carbide construction.

This undercut end mill is suited for die and mold work, aerospace component machining, and general precision milling where undercut profiles or lollipop-style relief cuts are required. It fits 0.5-inch shank tool holders and is run by machinists and toolroom professionals on CNC vertical and horizontal machining centers. The 3-inch overall length (OAL) and 0.323-inch neck diameter make it appropriate for cavity and pocket work where clearance below the shoulder is critical.

Key Features

• 270-degree wrap angle enables true undercut and relief-cut geometry inaccessible to standard end mills
• AlTiN coating improves heat and oxidation resistance for extended tool life in hard and ferrous materials
• Solid carbide construction provides stiffness and dimensional stability at high spindle speeds
• 4-flute right-hand cutting, right-hand flute direction for efficient chip evacuation
• 1.0-inch neck length with 0.323-inch neck diameter allows reach into deep cavities
• Single-end design with 0.5-inch shank for direct chuck or collet mounting

Compatibility

Designed for use in standard 0.5-inch shank toolholders including ER collet chucks, end mill holders, and shrink-fit systems on CNC machining centers requiring undercut or lollipop-profile end mill tooling.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC tooling setup and cutting parameters. Ensure the machine spindle is fully stopped and the tool path is programmed for the correct cutting direction before engaging the workpiece. Confirm runout at the collet and tool tip before production cuts, as excessive runout accelerates wear on undercut geometry. Follow the tool manufacturer's recommended speeds and feeds for the specific workpiece material and coating type.
