Harvey Tool 72445-C3 Chamfer Mill 3/16 in Solid Carbide

Product Description

The HARVEY TOOL 72445-C3 is a solid carbide chamfer mill designed for precise chamfering, deburring, and countersinking operations on metal workpieces. The cutter measures 3/16 inches in diameter with a 90-degree included angle and a right-hand cutting direction, making it suited for clean, accurate edge preparation. With an AlTiN (aluminum titanium nitride) coating, this tool handles elevated cutting temperatures and resists wear in demanding machining environments. Two flutes provide a balance of chip clearance and edge strength at this small diameter. Overall length is 2 inches with a matching 3/16-inch shank diameter. Machinists and toolroom operators install this tool in standard CNC mills and manual machines.

This chamfer mill is used in metalworking applications where consistent edge chamfers, spot drilling prep, or deburring are required. Its compact 3/16-inch diameter is well suited for tight-clearance areas and small-feature work on ferrous and non-ferrous materials. The AlTiN coating extends tool life in dry or semi-dry cutting conditions, particularly in steels, stainless, and cast iron. Single-end geometry keeps the tool compact and easy to index in a standard collet or end mill holder.

Key Features

• Solid carbide construction for rigidity and wear resistance at small diameters
• AlTiN coating improves heat resistance and extends tool life in ferrous materials
• 90-degree included angle for standard chamfer and countersink profiles
• Right-hand cutting direction compatible with conventional CNC spindle rotation
• 2-flute design balances chip evacuation and edge strength
• Matched 3/16-inch cutter and shank diameter for simplified toolholder selection

Compatibility

Designed as an OEM-style replacement or direct-use chamfer mill compatible with standard collet chucks, ER collet systems, and end mill holders accepting a 3/16-inch shank diameter.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from its holder. Seat the shank fully into the collet or holder and torque the retention nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning production cuts, as excessive runout accelerates wear on small-diameter carbide tools.
