Promax 108-03216 Square End Mill 1/2 in 2 Flute Carbide Zrn

Product Description

The PROMAX 108-03216 is a solid carbide square end mill designed for precision milling operations across a wide range of materials. Built from micrograin carbide and finished with a zirconium nitride (ZrN) coating, this tool delivers extended wear resistance and improved surface finish in demanding cutting environments. It features a 0.5-inch cutting diameter, a 1.25-inch length of cut, and a 3-inch overall length. The 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and smooth cutting action. Licensed machinists and CNC operators in job shop, production, and tool room settings are the primary users.

This end mill is suited for milling applications in ferrous and non-ferrous metals, plastics, and composites where a long-reach configuration is required. The centercutting design allows for plunge entry as well as standard peripheral milling. Right-hand cut and right-hand flute orientation make it compatible with standard spindle configurations on vertical and horizontal machining centers as well as knee mills. The long series classification provides additional reach for deep pocket and stepped-feature work that shorter tools cannot access.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN coating reduces friction and extends tool life in abrasive materials
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting capability allows direct plunge entry
• Long series length provides extra reach for deep pockets and stepped features
• Right-hand cut and right-hand flute for standard spindle compatibility

Compatibility

Designed as a direct-fit replacement for 0.5-inch shank square end mill applications on standard CNC machining centers and manual mills using ER or similar collet systems sized for 0.5-inch tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked before inserting or removing tooling. Seat the 0.5-inch shank fully into the collet or tool holder and torque the retention nut to the tool holder specification before operation. Verify runout with a dial indicator before beginning a production run to confirm proper seating.
