Accupro 12183551 Square End Mill 7/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12183551 is a solid carbide square end mill designed for precision milling operations in metal-cutting applications. Built from micrograin carbide and finished with an AlTiN coating, this tool delivers heat resistance and edge retention under demanding cutting conditions. It features a 7/16 inch diameter, a 1 inch length of cut, and a 4 inch overall length, making it suited for longer-reach slotting, profiling, and peripheral milling. Installed in CNC machining centers and manual mills, this end mill is the choice of machinists and tool-and-die professionals working in ferrous and non-ferrous materials.

This end mill fits standard 7/16 inch collets and tool holders used in vertical machining centers and knee mills. The long-length configuration provides clearance in deep-pocket and stepped-workpiece setups. The 40-degree helix angle promotes efficient chip evacuation during climb and conventional milling. The centercutting geometry allows direct plunge entry into workpiece material without a pre-drilled hole, adding versatility across roughing and finishing passes.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN coating provides thermal protection in high-speed ferrous machining
• 40-degree helix angle promotes aggressive chip evacuation
• Centercutting design allows direct plunge milling
• Right-hand cut and right-hand spiral flute configuration
• Long-length body with 1 inch LOC supports deep-pocket applications

Compatibility

Designed for use in standard 7/16 inch tool holders and collet chucks on CNC vertical machining centers and manual milling machines. Fits any machine spindle accepting a 7/16 inch shank diameter tooling system.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware per the tool holder manufacturer's specification. Verify runout with a dial indicator before initiating a cut to prevent premature tool wear or workpiece damage.
