Harvey Tool 945562-C3 Square End Mill 1/16 in 3 Flute

Product Description

The HARVEY TOOL 945562-C3 is a solid carbide square end mill designed for high-precision milling in demanding machining environments. With a 1/16 inch (0.0625 inch) cutting diameter and a 3/32 inch length of cut, this tool is built for fine detail work, slotting, and profiling in tight geometries. Three flutes and a 30-degree right-hand helix provide a balance of chip evacuation and surface finish quality. An AlTiN coating adds thermal resistance and wear protection, making this end mill well-suited for harder workpiece materials and dry or high-speed cutting conditions. Licensed machinists and CNC tooling technicians are the primary installers and operators.

This end mill is used in CNC machining centers for small-feature milling operations where a compact cutting diameter is required. The extended reach design, with a 1/4 inch reach length and a 1/8 inch shank diameter, allows access to recessed features and narrow pockets. It is a single-end, center-cutting tool suitable for plunge entry as well as conventional profiling passes. Typical applications include precision component machining in aerospace, medical device, and mold-and-die industries where tight tolerances and fine finishes are required.

Key Features

• 1/16 inch cutting diameter for fine-detail and small-feature milling
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for thermal protection and extended tool life in hard materials
• 3-flute geometry balances chip clearance with surface finish quality
• 30-degree right-hand helix for smooth cutting action
• Extended reach with 1/4 inch reach length for access to recessed features
• Center-cutting design allows direct plunge entry

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining applications requiring a 1/8 inch shank and 1/16 inch cutting diameter.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. The tool should be seated securely in a compatible collet or end mill holder rated for the 1/8 inch shank diameter, and runout should be verified before operation. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Follow applicable shop safety procedures and machine manufacturer guidelines for tool clamping torque and maximum RPM for this cutter diameter and material combination.
