Harvey Tool 878445-C3 Chamfer Mill 4mm 2 Flute Carbide

Product Description

The HARVEY TOOL 878445-C3 is a solid carbide chamfer mill designed for precise chamfering, deburring, and edge-breaking operations on a wide range of workpiece materials. The tool features a 4 mm cutter head diameter with a 2-flute, right-hand cutting geometry that delivers clean, controlled cuts at the spindle. An AlTiN coating provides elevated heat resistance and extended tool life in harder ferrous and non-ferrous materials. With an overall length of 50 mm and a matching 4 mm shank diameter, this compact tool suits high-speed machining centers and CNC mills where rigidity and precision are required.

This chamfer mill is suited for production and job-shop environments where consistent edge preparation is critical. The short length of cut of 2 mm makes it well suited for light chamfering passes on parts where minimal material removal is needed at the edge. Machinists and CNC operators working on steel, stainless, aluminum, and similar materials will find the AlTiN coating particularly effective for maintaining cutting performance at elevated temperatures without coolant in some applications.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for heat resistance and extended tool life in hard materials
• Right-hand cutting direction compatible with standard CNC spindle rotation
• 4 mm shank diameter matches common collet sizes for secure tool holding
• 2-flute geometry for efficient chip evacuation during chamfering passes
• Compact 50 mm overall length minimizes overhang and deflection

Compatibility

Designed as an OEM-style replacement and direct-fit chamfer mill for CNC machining centers and manual mills accepting a 4 mm shank collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle before inserting or removing tooling from the collet or tool holder. Ensure the shank is fully seated and the collet nut is torqued per the tool holder manufacturer guidelines before initiating a cutting program. Inspect the cutting edges for chipping or wear before each use and replace the tool if edge integrity is compromised.
