Harvey Tool 978141-C3 Chamfer Mill 3 Flute Altin 3/16 Inch

Product Description

The HARVEY TOOL 978141-C3 is a solid carbide chamfer mill designed for precision chamfering and deburring operations on ferrous and non-ferrous materials. This single-end tool features three right-hand cutting flutes and carries an AlTiN coating for improved heat resistance and tool life at elevated cutting speeds. The 3/16-inch shank diameter and 2-inch overall length make it well suited for use in compact setups and smaller spindle toolholders. With a 0.085-inch length of cut and dual included angles of 82 and 98 degrees, it handles both standard and back-chamfer geometry in a single tool. Installed by machinists and CNC operators in production and job shop environments.

This chamfer mill is used in milling operations where consistent chamfer geometry and edge preparation are required. It performs well on steel, stainless, and hardened materials where the AlTiN coating helps resist heat buildup and extends cutting life. The compact 3/16-inch shank fits standard collet chucks and toolholders common to vertical machining centers and manual mills. It is suited for chamfering drilled holes, milling part edges, and deburring in both prototype and production runs.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting applications
• AlTiN coating improves heat resistance and extends tool life on ferrous materials
• Three right-hand flutes provide a balance of chip clearance and surface finish quality
• Dual included angles of 82 degrees and 98 degrees allow versatile chamfer geometry in one tool
• 0.085-inch length of cut suits fine edge preparation and precise chamfer sizing
• Single-end design with 3/16-inch shank fits standard collet and toolholder systems

Compatibility

Designed as an OEM-style solid carbide chamfer mill for use with standard 3/16-inch collet chucks and compatible toolholders on vertical machining centers and CNC milling machines.

Installation Notes

This tool is installed by machinists or CNC operators in a standard collet chuck or end mill holder. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. Verify runout after installation, as excessive runout will reduce tool life and chamfer accuracy. Follow the tool manufacturer and machine builder recommendations for appropriate feed rates and spindle speeds based on material and coating type.
