Accupro 12182921 Square End Mill 15/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12182921 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide and finished with an AlTiN (aluminum titanium nitride) coating, it handles high-heat cutting environments common in ferrous and hardened materials. The 15/32 inch (0.4688 inch) cutting diameter pairs with a 4-flute spiral configuration and a 40-degree helix angle to promote efficient chip evacuation and smooth surface finishes. At 2-1/2 inches overall length with a 5/8 inch length of cut, this is a stub-length tool optimized for rigidity in short-reach operations. CNC machinists and manual mill operators install this tool in production and job-shop environments.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous metals, stainless steel, and similar materials where an AlTiN coating provides thermal protection and wear resistance. The right-hand cut and right-hand flute orientation make it compatible with standard spindle configurations. Its centercutting geometry allows plunge entry, giving machinists flexibility when programming tool paths that require direct Z-axis entry into a workpiece.

Key Features

• Micrograin solid carbide construction for enhanced hardness and wear resistance
• AlTiN finish extends tool life in high-temperature cutting conditions
• 40-degree helix angle with spiral flute for efficient chip evacuation
• Centercutting design allows direct plunge milling
• Right-hand cut, right-hand flute for standard spindle use
• Stub-length body maximizes rigidity and reduces deflection

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for 1/2 inch shank tool holders, collet chucks, and end mill holders used in CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1/2 inch shank fully and evenly in the tool holder collet before tightening to manufacturer torque specifications for the holder type in use. Verify runout with a dial indicator before beginning a production cut to confirm proper seating and minimize tool wear.
