Promax 190-03214 Solid Carbide Square End Mill 1/2 Inch

Product Description

The PROMAX 190-03214 is a 4-flute solid carbide square end mill designed for both roughing and finishing operations in a single tool. Built around a 1/2 inch cutting diameter, it features a 40-degree helix angle and an AlTiN coating that extends tool life in ferrous and high-temperature alloy materials. The chipbreaker geometry reduces cutting forces during aggressive material removal, making this end mill well suited for high-feed roughing passes where heat and vibration management are priorities. Machinists and tool-and-die professionals working with steel, stainless, and hardened materials are the primary users.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where a 1/2 inch shank holder is available. The regular-length, single-end design keeps overhang short, improving rigidity during slotting, profiling, and pocketing operations. The 1-1/4 inch length of cut accommodates most standard depth-of-cut requirements in production and job-shop environments without sacrificing stiffness. The AlTiN finish makes it especially effective in dry or minimal-lubrication cutting strategies.

Key Features

• 4-flute solid carbide construction for rigidity and wear resistance
• AlTiN coating for elevated heat resistance and extended tool life
• 40-degree helix angle promotes smooth chip evacuation and reduced chatter
• Chipbreaker geometry enables aggressive roughing while maintaining finish capability
• Right-hand cut and right-hand flute direction - compatible with standard spindle rotation
• Regular length, single-end design minimizes overhang and maximizes rigidity

Compatibility

Designed as an OEM-style replacement end mill for use in standard 1/2 inch collet chucks, end mill holders, and hydraulic tool holders on CNC and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and the control in E-stop or lock-out condition. Ensure the shank is seated fully and evenly in the holder and that the collet or set-screw torque follows the toolholder manufacturer's specifications. Inspect the cutting edges and coating for chips or wear before each use. Do not exceed the end mill's rated depth-of-cut for the material being machined.
