Harvey Tool 771545-C3 Chamfer Mill 0.25 in 4 Flute Carbide

Product Description

The HARVEY TOOL 771545-C3 is a solid carbide chamfer mill designed for precision chamfering, deburring, and edge-breaking operations on ferrous and non-ferrous materials. With a 0.25 inch cutter head diameter and four flutes, this single-end tool delivers clean, consistent chamfer geometry at the spindle. The AlTiN coating provides elevated heat resistance and surface hardness, extending tool life in demanding milling applications. At 4 inches overall length with a 1 inch shank diameter, it is built for rigid setups on CNC machining centers. Machinists and toolroom operators rely on this geometry for high-repeatability chamfering across production and prototype work.

This chamfer mill suits CNC milling applications where controlled edge preparation is required on machined components. The right-hand cutting direction and four-flute configuration make it well-suited for finish chamfering on steel, stainless, and hardened materials where the AlTiN coating provides a thermal barrier. The 1 inch shank diameter accommodates standard toolholders used in vertical and horizontal machining centers. Typical applications include part deburring after profile milling, countersink preparation, and cross-hole chamfering in production environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard material applications
• AlTiN coating enhances heat resistance and extends tool life in ferrous machining
• Four-flute design provides smooth cutting action and improved surface finish on chamfered edges
• 0.098 inch length of cut for precise, controlled edge engagement
• Right-hand cutting direction compatible with standard CNC spindle rotation
• Single-end geometry for straightforward setup and tool path programming

Compatibility

Designed as an OEM-style solid carbide chamfer mill compatible with standard 1 inch diameter toolholders on CNC vertical and horizontal machining centers.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom personnel. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 1 inch shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before production use to ensure chamfer consistency and avoid premature tool wear.
