Promax 112-02414 Square End Mill 3/8 Inch 5 Flute Carbide

Product Description

The PROMAX 112-02414 is a 5-flute solid carbide square end mill designed for high-performance milling in demanding machining environments. It features an AlTiN (aluminum titanium nitride) coating that extends tool life by reducing heat buildup at the cutting edge. Built from micrograin carbide stock, this end mill delivers the rigidity and edge retention needed for harder workpiece materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. It is a centercutting tool, allowing direct plunge entry into the workpiece without a pre-drilled start hole. Machinists and CNC operators in job shops, production facilities, and toolrooms are the primary users.

This end mill is suited for milling operations on ferrous metals, hardened steels, stainless, and similar materials where an AlTiN-coated micrograin carbide tool is the appropriate choice. The spiral flute geometry and right-hand cut with right-hand flute configuration make it compatible with standard CNC machining centers and manual knee mills running conventional or climb milling passes. The Series 112 designation from PROMAX identifies a consistent line of solid carbide square end mills built to close diameter tolerances.

Key Features

• 5-flute design increases feed rate capability and improves surface finish compared to 4-flute tools
• AlTiN coating provides high-temperature resistance and extended tool life in ferrous and hardened materials
• Micrograin solid carbide construction delivers superior edge retention and rigidity
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting geometry allows direct plunge milling without a pilot hole
• Close diameter tolerances (+0.000 / -0.002 inches on mill diameter) support consistent fit and finish results

Compatibility

Designed as a standard shank solid carbide square end mill for use in CNC machining centers, vertical mills, and similar equipment accepting a 3/8 inch straight shank tool holder or collet.

Installation Notes

Installation is performed by a machinist or CNC operator using a collet chuck, end mill holder, or shrink-fit toolholder rated for the 3/8 inch shank diameter. Ensure the machine spindle is fully stopped and the tool is properly seated and torqued to holder specifications before initiating a cut. Confirm runout with a dial indicator before production use to protect both the tool and the workpiece. Always follow shop safety protocols and machine manufacturer guidelines when changing cutting tools.
