Harvey Tool 48545-C3 Chamfer Mill 1/4 in 3 Flute Carbide

Product Description

The HARVEY TOOL 48545-C3 is a solid carbide chamfer mill designed for deburring, chamfering, and edge-breaking operations on machined workpieces. Built with a 1/4 inch cutter head diameter and a 90 degree included angle, this single-end tool produces consistent, repeatable chamfers in a single pass. The AlTiN coating provides thermal resistance and extended tool life in ferrous and hardened materials. With a 4 inch overall length and 1/4 inch shank diameter, it fits standard collet chucks and end mill holders used on CNC machining centers and manual mills. Machinists and toolroom operators working in job shops, aerospace, and general manufacturing rely on this geometry for clean edge prep.

This chamfer mill is suited for chamfering drilled holes, milled edges, and countersink profiles on steel, stainless steel, cast iron, and similar materials. The 3-flute configuration balances chip evacuation with surface finish, making it effective at moderate to high spindle speeds. The right-hand cutting direction matches standard spindle rotation on vertical and horizontal machining centers. It is sized for light-duty to medium-duty chamfering where a compact 1/4 inch diameter is appropriate, such as small-bore hole chamfering or detail edge work on tight-tolerance components.

Key Features

• 90 degree included angle for standard chamfer and countersink profiles
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for thermal protection and extended tool life in ferrous materials
• 3-flute design balances chip flow and surface finish quality
• Right-hand cutting direction for use with standard CNC and manual mill spindles
• 1/4 inch shank diameter fits common collet and end mill holder systems

Compatibility

Designed as a direct-fit chamfer mill for standard 1/4 inch collet chucks and end mill holders on CNC machining centers, knee mills, and similar equipment with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom 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 into the collet or holder before tightening to manufacturer-specified torque for that holder type. Verify runout with a dial indicator after seating to maximize tool life and chamfer accuracy.
