Promax 112-03214 Square End Mill 0.5 in 5 Flute Carbide Altin

Product Description

The PROMAX 112-03214 is a solid carbide square end mill engineered for high-performance milling in demanding machining environments. With a 0.5-inch cutting diameter, 5 spiral flutes, and an AlTiN (aluminum titanium nitride) coating, this tool is built for aggressive material removal in ferrous and hardened materials. The micrograin carbide substrate provides the edge strength and wear resistance required in production CNC machining. A 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Machinists and tool-and-die professionals rely on this series for precision profiling, slotting, and side milling operations where tight tolerances and consistent surface finish matter.

This end mill is suited for use on CNC machining centers and manual mills in job shops, production facilities, and tool rooms. The centercutting geometry allows plunge milling in addition to conventional lateral passes, expanding its utility across a range of operations. The right-hand cut and right-hand flute configuration is standard for conventional spindle setups. Series 112 tools are designed for regular-length applications where a 1.25-inch length of cut and 3-inch overall length satisfy the majority of general-purpose milling jobs without sacrificing rigidity.

Key Features

• Solid micrograin carbide construction for superior edge retention and tool life
• AlTiN coating enhances heat resistance and reduces friction at high cutting speeds
• 5-flute design increases feed rates and improves surface finish compared to 4-flute equivalents
• 40-degree helix angle promotes effective chip evacuation during deep passes
• Centercutting capability allows plunge entry without a pre-drilled hole
• Right-hand cut, right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as a standard shank end mill compatible with 0.5-inch ER collets, milling chucks, and hydraulic toolholders on CNC machining centers and manual knee mills with appropriate spindle tooling.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully powered down and the tool is securely seated in a clean, burr-free collet or chuck before tightening. Verify runout with a dial indicator before beginning any cutting operation, as excessive runout will accelerate edge wear and compromise tolerance. Follow the toolholder manufacturer's torque specifications when securing the retention knob or collet nut.
