Harvey Tool 23202-C3 Undercut End Mill 1/32 in 2-flute Altin

Product Description

The HARVEY TOOL 23202-C3 is a single-end undercut end mill designed for machining operations that require relief below the cutting zone. Built from solid carbide with an AlTiN coating, it delivers hardness and heat resistance suited for ferrous and hardened materials. The tool measures 0.0312 inches in diameter with a 270-degree wrap angle and a length of cut of 0.027 inches. The 2-flute, right-hand cutting geometry provides chip clearance in tight pockets. With a shank diameter of 0.125 inches and an overall length of 1.5 inches, it fits standard collet systems common in CNC milling setups. Machinists and tool-and-die professionals install this tool where standard end mills cannot reach undercut profiles.

This undercut end mill is intended for precision CNC milling applications including undercutting, T-slot finishing, and relieving edges in tight geometries. Its small diameter and compact neck make it appropriate for micro-machining work in mold making, die work, and component finishing. The AlTiN coating extends tool life when cutting alloy steels, stainless steels, and hardened materials at elevated spindle speeds. This is a single-end tool sold individually.

Key Features

• 270-degree wrap angle enables undercut profiles not reachable by standard end mills
• Solid carbide construction provides rigidity and wear resistance at small diameters
• AlTiN coating improves heat resistance and extends tool life in ferrous materials
• 2-flute right-hand geometry supports chip evacuation in confined pockets
• Neck diameter of 0.0160 inches allows clearance in deep or narrow features
• Single-end design with 0.125-inch shank fits standard ER and precision collet chucks

Compatibility

Designed as an OEM-style replacement and direct-fit undercut end mill for CNC machining centers accepting a 0.125-inch shank diameter in standard ER collet or precision collet systems.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC tooling setup. Power down and lock out the spindle before changing tools. Seat the shank fully in the collet to the recommended engagement depth and torque the collet nut per the collet manufacturer specification. At this diameter, minimize runout and verify tool projection before cutting to reduce deflection risk.
