Harvey Tool 18435-C3 Chamfer Mill 3/8 in 3 Flute Carbide Altin

Product Description

The HARVEY TOOL 18435-C3 is a solid carbide chamfer mill designed for deburring, chamfering, and edge-breaking operations on ferrous and non-ferrous workpieces. The tool features a 3/8-inch cutter head diameter, a 70-degree included angle, and three right-hand cutting flutes ground from solid carbide stock. An AlTiN coating improves surface hardness and heat resistance, extending tool life in dry or semi-dry cutting conditions. The 3/8-inch shank diameter and 2.5-inch overall length make this mill compatible with standard collet and end-mill holders on CNC machining centers and manual mills alike. Machinists and tool-and-die professionals are the primary users of this type of tooling.

This chamfer mill is suited for single-end chamfering operations in production and job-shop environments. It handles edge preparation on steel, stainless, cast iron, aluminum, and similar machinable materials. The right-hand cutting direction and three-flute geometry support smooth chip evacuation while maintaining edge sharpness across multiple passes. Typical applications include pre-weld chamfers, thread lead-ins, and cosmetic edge breaks on machined components where consistent angle and finish quality are required.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlTiN coating improves heat resistance and extends tool life in dry cutting
• 70-degree included angle for standard chamfering and edge-prep work
• Three right-hand flutes promote clean chip evacuation
• Single-end design with 3/8-inch shank for broad holder compatibility
• 0.2290-inch length of cut supports controlled, repeatable chamfer depth

Compatibility

Designed as an OEM-style replacement and standard tooling option for use in 3/8-inch collet chucks, ER collet holders, and end-mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Secure the shank fully within the collet or tool holder to the recommended gauge-line depth before tightening. Ensure the spindle is at a complete stop and the machine is in a safe state before loading or unloading the tool. Verify runout after installation to avoid premature edge wear or chipping on the carbide flutes.
