Harvey Tool 52847-C3 Undercut End Mill 3/64 Inch Altin

Product Description

The HARVEY TOOL 52847-C3 is a solid carbide undercut end mill designed for high-precision machining applications where standard end mills cannot reach. With a 3/64-inch (0.0469 inch) mill diameter and a 270-degree wrap angle, this tool enables profile milling, undercutting, and slot work in confined or undercut geometries. The 2-flute configuration with right-hand cutting and right-hand flute direction provides efficient chip evacuation in tight spaces. An AlTiN coating delivers heat resistance and extended tool life in hard and abrasive materials. This tool is used by machinists and tool-and-die professionals operating CNC milling centers in production and prototype environments.

This end mill is suited for precision work in ferrous and hardened materials where undercut profiles or recessed features must be machined. The 1/8-inch shank diameter fits standard collets on vertical and horizontal milling machines. The 0.0401-inch length of cut, 0.0938-inch neck length, and 0.0290-inch neck diameter allow access to shallow undercut features without interference from the shank. It is a single-end tool intended for single-setup undercut operations on CNC machining centers.

Key Features

• 270-degree wrap angle enables true undercut and profile milling in recessed geometries
• AlTiN coating provides high heat resistance and extended tool life in abrasive and hardened materials
• Solid carbide construction delivers rigidity and dimensional stability at high RPM
• 2-flute, right-hand cut design supports chip clearance in narrow undercut pockets
• 1/8-inch shank fits standard ER and precision collet systems
• Compact neck geometry minimizes deflection during undercut passes

Compatibility

Designed for use in CNC vertical and horizontal milling centers accepting a 1/8-inch shank diameter. Suitable for applications requiring undercut end mill tooling in solid carbide with AlTiN coating.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine in a safe, locked-out state per applicable shop safety procedures. Seat the 1/8-inch shank fully into the collet and torque the collet nut to the collet manufacturer specification. Verify runout with a dial indicator before cutting. Do not exceed the tool manufacturer recommended feed and speed parameters for the workpiece material and tool diameter.
