Harvey Tool 18518-C3 Chamfer Mill 1/4 in 3 Flute Solid Carbide

Product Description

The HARVEY TOOL 18518-C3 is a single-end chamfer mill designed for precision chamfering and deburring operations in metalworking applications. Built from solid carbide and finished with an AlTiN (Aluminum Titanium Nitride) coating, this tool delivers hardness and heat resistance suited for cutting ferrous metals, stainless steel, and high-temperature alloys. It carries a 1/4 inch cutter head diameter, an 18-degree included angle, and a 0.301 inch length of cut. The three-flute design balances chip evacuation with surface finish quality. Overall length is 2-1/2 inches with a 1/4 inch shank diameter. Right-hand cutting direction. Installed by machinists and CNC operators in shop environments requiring consistent edge preparation.

This chamfer mill is suited for use on CNC machining centers and manual mills where edge breaking, chamfering, and countersinking on tight-tolerance workpieces are required. The AlTiN coating extends tool life at elevated cutting temperatures, making it a practical choice for dry or minimal-lubrication machining of hardened steels, titanium, and similar materials. The compact 1/4 inch diameter makes it well matched to smaller features and confined geometry where larger tooling cannot reach.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for improved heat resistance and extended tool life in dry cutting conditions
• 18-degree included angle for consistent chamfer geometry
• Three-flute design balances chip clearance with finish quality
• Right-hand cutting direction compatible with standard CNC and manual mill spindles
• 0.301 inch length of cut on a compact 1/4 inch diameter body

Compatibility

Designed for use with standard 1/4 inch collets and tool holders on CNC machining centers and manual milling machines requiring a right-hand single-end chamfer mill.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the 1/4 inch shank in a properly sized collet or end mill holder and torque to the tool holder manufacturer specification. Confirm spindle direction is set to right-hand rotation before engaging the cut. Inspect the cutting edges for chips or coating damage before each use, and replace tooling that shows signs of wear to maintain edge quality and dimensional accuracy.
