Accupro 12179709 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The ACCUPRO 12179709 is a solid carbide square end mill designed for precision milling operations in metal, alloy, and composite materials. It features a 1/4 inch cutting diameter, a 3/4 inch length of cut, and a 3-flute spiral geometry with a 40-degree helix angle. The micrograin carbide substrate delivers hardness and edge retention under demanding cutting conditions. An AlTiN coating reduces heat buildup and extends tool life in dry and high-speed machining applications. This end mill is centercutting, allowing plunge entry, and runs right-hand cut with right-hand flutes. It is suited for use by machinists and tooling professionals in job shop and production environments.

This end mill is used for slotting, profiling, and peripheral milling in CNC machining centers and manual mills. Its regular-length configuration and 1/4 inch shank make it compatible with standard collet chucks and end mill holders in both vertical and horizontal setups. The 40-degree helix promotes smooth chip evacuation, making it a practical choice for finishing passes in steel, stainless, aluminum, and similar materials. It ships as a single unit and is suited for low-volume tooling restocks or individual job requirements.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• AlTiN coating for thermal protection in high-speed and dry cutting
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute configuration
• 3-flute design balances chip clearance and surface finish

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 1/4 inch collet chucks, end mill holders, and milling arbors 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 locked out before changing tooling. Seat the shank fully in the collet or holder and torque the retention hardware to the machine manufacturer's specification. Inspect the cutting edges for chips or damage before use and verify runout with a dial indicator before beginning a cut.
