Promax 109-03236 Square End Mill 0.5in 3-flute Carbide

Product Description

The PROMAX 109-03236 is a solid carbide square end mill designed for precision milling operations in metal, alloy, and composite workpiece materials. Built from micrograin carbide stock, it delivers a 0.5 inch cutting diameter with a 1.5 inch length of cut and a 3.5 inch overall length. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces, while the zirconium nitride (ZrN) finish improves surface hardness and wear resistance for extended tool life. Three spiral flutes with a right-hand cut and right-hand flute direction make this a standard-orientation tool for conventional milling setups. The centercutting geometry allows plunge entry directly into the workpiece.

This end mill is suited for general-purpose and production milling in machine shops, toolrooms, and manufacturing environments. It fits standard 0.5 inch collets and tool holders commonly found on CNC machining centers and manual knee mills. Typical applications include slot milling, profile milling, and step cutting in ferrous and non-ferrous metals where tight dimensional tolerances are required. The micrograin carbide substrate makes it particularly effective in harder workpiece materials where high-speed steel tooling would wear prematurely.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• ZrN (zirconium nitride) coating extends tool life and improves surface finish on the cut
• 40-degree helix angle promotes efficient chip flow and reduces heat buildup
• Centercutting design allows direct plunge milling without a pre-drilled pilot hole
• Three spiral flutes with right-hand cut and right-hand flute direction for standard CNC and manual mill setups
• Tight mill diameter tolerance of plus 0.000 / minus 0.002 inches ensures consistent fit and finish

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for 0.5 inch collet systems and end mill holders on standard CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before inserting or removing the tool from the collet or holder. Ensure the shank is fully seated to the required insertion depth and that the collet or set-screw holder is torqued according to the machine tool manufacturer's specification. Inspect the cutting edges and coating for chips or wear before each use; damaged carbide tooling should be replaced, not re-run.
