Promax 109-04036 Square End Mill 5/8 in 3 Flute Solid Carbide

Product Description

The PROMAX 109-04036 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin carbide, this tool provides high rigidity and wear resistance across demanding machining environments. It features a 5/8 inch cutting diameter, a 1-3/4 inch length of cut, and a 4-inch overall length, making it well-suited for slotting, profiling, and contouring applications. The zirconium nitride (ZrN) coating reduces friction and extends tool life. This end mill is installed and operated by machinists and CNC programmers in production and job-shop settings.

The 109-04036 is used in vertical and horizontal milling machine setups, as well as CNC machining centers requiring a 5/8 inch shank. It is a centercutting tool capable of plunge milling in addition to peripheral cutting. The right-hand cut and right-hand spiral flute configuration, combined with a 40-degree helix angle, promotes efficient chip evacuation during full-depth slotting and side milling passes. It is suited to general-purpose roughing and finishing operations where dimensional accuracy is critical.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• ZrN (zirconium nitride) coating reduces friction and heat buildup at the cutting edge
• 40-degree helix angle promotes aggressive chip evacuation in deep-slot applications
• Centercutting geometry allows direct plunge entry without a pilot hole
• 3-flute design balances chip clearance and cutting edge strength for versatile material removal
• Right-hand cut, right-hand flute spiral configuration for standard CNC spindle compatibility

Compatibility

Designed as a Series 109 square end mill with a 5/8 inch straight shank, compatible with standard ER collets, end mill holders, and milling chucks accepting 5/8 inch shank tooling on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully in the collet or tool holder and torque the retention mechanism to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning production cuts, as excessive runout will reduce tool life and dimensional accuracy.
