Promax 109-03224 Square End Mill 1/2 in 3 Flute Solid Carbide

Product Description

The PROMAX 109-03224 is a solid carbide square end mill designed for precision milling in demanding shop environments. It features a 1/2 inch cutting diameter, a 5/8 inch length of cut, and a 2-1/2 inch overall length. Built from micrograin carbide with an AlTiN coating, this end mill delivers extended tool life when cutting ferrous metals, hardened steels, and abrasive alloys. The 3-flute geometry balances chip evacuation with rigidity, making it well suited to slotting, profiling, and peripheral milling operations. A 35-degree helix angle promotes smooth cutting action and reduces vibration at the tool tip.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills across job shop and production environments. It is a centercutting design, allowing plunge entry without a pre-drilled hole. The right-hand cut and right-hand spiral flute configuration is standard for conventional and climb milling with typical spindle rotation. It is sold individually and is suited for tool rooms, maintenance shops, and production floors that require a reliable general-purpose carbide end mill in the 1/2 inch diameter class.

Key Features

• Solid micrograin carbide construction for superior hardness and wear resistance
• AlTiN coating for high-temperature performance and extended tool life in ferrous and hardened materials
• 3-flute design balances chip clearance and core strength for slotting and profiling
• 35-degree helix angle reduces cutting forces and improves surface finish
• Centercutting capability allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute - standard configuration for most CNC and manual milling setups

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 1/2 inch straight-shank tool holders, collets, and end mill adapters used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1/2 inch shank fully into the collet or end mill holder and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator after installation before beginning a cut.
