Accupro 12183372 Square End Mill 3/4 in 4 Flute Carbide Ticn

Product Description

The ACCUPRO 12183372 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. It features a 3/4 inch cutting diameter, a 3 inch length of cut, and a 6 inch overall length, classifying it as an extra-long reach tool. The 4-flute, spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN (Titanium Carbonitride) coating adds surface hardness and thermal resistance, extending tool life in ferrous and non-ferrous materials. Micrograin carbide substrate provides the edge integrity needed for consistent performance at higher feed rates and depths of cut.

This end mill is suited for slotting, profiling, and peripheral milling operations on machining centers and CNC mills. The extra-long 6 inch OAL makes it appropriate for deep-pocket work and applications where standard-length tools cannot reach. Right-hand cut and right-hand flute configuration is the conventional setup for standard CNC spindle rotation. Centercutting capability allows direct plunge entry without a pre-drilled pilot hole, adding flexibility to the toolpath.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating for improved wear resistance and reduced friction
• 40-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting design allows direct plunge milling
• Extra-long 6 inch OAL for deep-reach and deep-pocket applications
• Right-hand cut, right-hand spiral flute for standard CNC spindle use

Compatibility

Designed for use in standard 3/4 inch collets, end mill holders, or hydraulic chucks on CNC machining centers and manual knee mills configured for right-hand spindle rotation.

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 shank fully in the holder to the recommended minimum engagement depth and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the TiCN coating and cutting edges before use — do not run a chipped or cracked carbide end mill.
