Promax 109-06444 Square End Mill 1 in 3 Flute Solid Carbide

Product Description

The PROMAX 109-06444 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 1 inch cutting diameter, a 3-3/8 inch length of cut, and a 6 inch overall length, making it well suited for deeper profile and slotting work. The 3-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and improved surface finish. An AlTiN coating provides thermal resistance and extended tool life when cutting hardened steels, stainless, and other demanding materials. The micrograin carbide substrate adds toughness and wear resistance throughout the cut.

This end mill is intended for use on CNC machining centers and manual knee mills in job shop, production, and toolroom environments. The centercutting design allows direct plunge entry, expanding its range of programming options. Right-hand cut and right-hand spiral flute configuration is standard for conventional spindle setups. The 1 inch shank diameter is sized for standard R8, CAT, BT, and HSK toolholders commonly found in professional machine shop setups. It is installed and operated by machinists and CNC programmers working with ferrous and non-ferrous alloys.

Key Features

• Solid micrograin carbide construction for improved wear resistance and dimensional stability
• AlTiN finish for high-heat resistance when cutting hardened and abrasive materials
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Centercutting design allows direct plunge milling without pre-drilled entry
• 3-flute configuration balances chip clearance and feed rate capability
• Right-hand cut, right-hand flute spiral for standard CNC and manual mill spindles

Compatibility

Designed as a direct-fit replacement or addition for standard 1 inch shank toolholding systems on CNC machining centers and manual mills. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before loading or removing tooling. Seat the shank fully into the toolholder and torque the retention mechanism to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate wear and degrade surface finish.
