Promax 131-03210 Chamfer Mill 4 Flute Solid Carbide

Product Description

The PROMAX 131-03210 is a solid carbide chamfer mill designed for chamfering, countersinking, and spotting operations on machined workpieces. Built to Series 131 standards, this double-end tool features a 1/2-inch cutter head diameter, a 1/2-inch shank diameter, and a 3-inch overall length. The 120-degree included angle makes it suitable for producing clean, consistent chamfers in a range of materials. The bright uncoated finish keeps the carbide substrate exposed for applications where coatings are unnecessary or undesirable. It is installed and operated by machinists and CNC operators in production and job-shop environments.

This chamfer mill is used in milling operations where edge preparation, deburring, or countersinking is required. The four-flute, right-hand cutting geometry provides balanced chip evacuation and surface finish quality during moderate to high feed-rate passes. It is suited for use on vertical machining centers, CNC mills, and manual knee mills across light-metal, steel, and similar workpiece materials. The double-end configuration allows for extended tool life before replacement is needed.

Key Features

• Solid carbide construction for rigidity and wear resistance
• 120-degree included angle for standard chamfering and countersinking
• Four flutes with right-hand cutting direction for balanced chip load
• Double-end design extends usable tool life
• Bright uncoated finish suitable for general-purpose machining applications
• 1/2-inch shank diameter for compatibility with standard collet and end-mill holders

Compatibility

Designed as an OEM-style replacement or direct-use chamfer mill for machining setups requiring a 1/2-inch shank, 120-degree included angle tool in chamfering, countersinking, or spotting applications.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the 1/2-inch shank in a properly sized collet or end-mill holder and torque the retention mechanism according to the toolholder manufacturer specifications. Ensure the spindle is fully stopped and the machine is in a locked-out state before tool changes. Verify runout with a dial indicator before beginning a production run to avoid premature tool wear or poor edge quality.
