Promax 109-03226 Square End Mill 0.5in 3 Flute Carbide Zrn

Product Description

The PROMAX 109-03226 is a solid carbide square end mill designed for precision milling in demanding shop environments. This single-end tool features a 0.5 inch cutting diameter, a 0.625 inch length of cut, and a 0.5 inch straight shank. The three-flute design with a 40-degree right-hand spiral flute geometry promotes efficient chip evacuation and smooth surface finishes in a range of ferrous and non-ferrous materials. A zirconium nitride (ZrN) finish provides added surface hardness and heat resistance at the cutting edge. The micrograin carbide substrate adds toughness and wear resistance for extended tool life in production and job-shop use.

This stub-length end mill is suited for general-purpose profiling, slotting, and peripheral milling operations on CNC machining centers and manual knee mills. The stub configuration improves rigidity in applications where tool deflection is a concern. It is appropriate for use in tool and die, aerospace component, and general metalworking applications where tight tolerances and consistent performance are required. Machinists and CNC programmers in production and prototype environments are the primary users of this tool.

Key Features

• Solid micrograin carbide construction for wear resistance and dimensional stability
• ZrN (zirconium nitride) coating for increased surface hardness and reduced heat buildup at the cutting edge
• 40-degree right-hand spiral flute geometry promotes efficient chip flow
• Three-flute design balances chip clearance with edge strength for a range of materials
• Stub length-of-cut configuration improves tool rigidity and reduces deflection
• Right-hand cut with square shank for standard collet and end mill holder compatibility

Compatibility

Designed as a direct-fit replacement for standard 0.5 inch shank end mill holders and collet-style toolholding systems used on CNC machining centers and manual milling machines within the PROMAX Series 109 product line.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or lockout state before inserting or removing the tool. Use a properly sized collet or end mill holder matching the 0.5 inch shank diameter and verify runout before engaging the workpiece. Refer to the machine manufacturer and tooling manufacturer guidelines for appropriate speeds, feeds, and depth-of-cut parameters.
