Harvey Tool 891045-C3 Chamfer Mill 1/4 in 3 Flute Carbide

Product Description

The HARVEY TOOL 891045-C3 is a solid carbide chamfer mill designed for chamfering, deburring, and edge-breaking operations on a wide range of workpiece materials. It features a 1/4 inch cutter head diameter, three flutes, and a 90-degree included angle with a double-end configuration. The cutting edges are coated with AlTiN (aluminum titanium nitride), which improves heat resistance and tool life during high-speed or dry machining. Overall length is 2-1/2 inches with a 1/4 inch shank diameter. This tool is intended for use by machinists and tool and die professionals working in production or job shop environments.

The 891045-C3 suits applications requiring consistent chamfer geometry on ferrous and non-ferrous materials. Its right-hand cutting direction and three-flute design provide smooth chip evacuation and a clean edge finish. The double-end geometry offers versatility for angled entry cuts and cross-hole chamfering. It is a practical choice for CNC milling centers and manual mills where a compact, precise chamfer tool is required.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for extended tool life in high-temperature cutting conditions
• 90-degree included angle suitable for standard chamfer and deburring work
• Double-end configuration provides added versatility for angled entry
• Three-flute design promotes efficient chip evacuation and surface finish
• Right-hand cutting direction compatible with standard CNC spindle rotation

Compatibility

Designed as a direct-fit replacement or addition for standard 1/4 inch collet tool holders on CNC milling machines and manual mills requiring a 90-degree solid carbide chamfer mill.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1/4 inch shank fully and evenly in a clean, properly sized collet or tool holder, and torque the retention mechanism per the machine manufacturer specifications. Verify runout with a dial indicator before beginning production cuts.
