Harvey Tool 945547-C3 Square End Mill 3/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 945547-C3 is a solid carbide square end mill designed for high-precision milling in demanding machining environments. With a 3/64 inch (0.047 inch) cutting diameter and three flutes, this end mill delivers clean, accurate cuts in tight tolerances. The AlTiN coating provides excellent heat resistance and hardness, extending tool life in ferrous and abrasive materials. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Machinists and tool-and-die professionals rely on this style of micro end mill for fine detail work, slotting, and contouring in production and prototype machining.

This end mill is suited for use on CNC machining centers handling small-feature work in steel, stainless steel, cast iron, and similarly hard materials where AlTiN coating performance is beneficial. The extended reach design, with a 3/16 inch reach length, allows access to features that standard-length end mills cannot reach. The 1/8 inch shank diameter is compatible with standard collet systems found on most CNC mills and toolroom machines. Single-end configuration means the tool is replaced rather than flipped when worn.

Key Features

• 3/64 inch (0.047 inch) cutting diameter for micro and fine-detail milling
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for extended tool life in ferrous and abrasive materials
• Three flutes with right-hand cut and right-hand flute direction
• 30-degree helix angle promotes efficient chip evacuation
• Extended reach design with 3/16 inch reach length for deep-feature access
• Center-cutting capable for plunge entry

Compatibility

Designed as a replacement or direct-use solid carbide square end mill for CNC machining centers and toolroom mills equipped with 1/8 inch collet or toolholder systems.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholder and collet torque procedures per the machine manufacturer's guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet to the recommended engagement depth to prevent pullout during cutting. Micro-diameter end mills are fragile — avoid side-loading or interrupted cuts beyond the tool's rated depth of cut range.
