Accupro 12181357 Square End Mill 0.2756 in 2 Flute Carbide

Product Description

The ACCUPRO 12181357 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous metals. It features a 0.2756 inch mill diameter, a 0.748 inch length of cut, and a 40-degree helix angle that promotes smooth chip evacuation and reduced cutting forces. The TiCN coating improves surface hardness and wear resistance, extending tool life in demanding applications. With two spiral flutes and a centercutting geometry, this end mill handles both peripheral and plunge cutting. It is installed and run by machinists and CNC operators working in job shops, toolrooms, and production environments.

This end mill is suited for slotting, profiling, and pocketing operations in a variety of workpiece materials. The micrograin carbide substrate provides the rigidity needed for tight-tolerance cuts. The 0.3150 inch shank diameter fits standard collets and toolholders. Its regular-length configuration makes it a practical choice for general-purpose CNC milling work where extended reach is not required. Right-hand cut and right-hand flute orientation are standard for conventional CNC spindle setups.

Key Features

• 0.2756 inch mill diameter with a mill diameter tolerance of +0.000 / -0.002 inches for precise fitment
• TiCN finish for improved wear resistance and surface hardness
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting geometry enables direct plunge entry into workpiece material
• Micrograin solid carbide substrate for rigidity and edge retention
• Right-hand cut and right-hand spiral flute - compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard collet chucks and end mill holders accepting a 0.3150 inch shank diameter in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator. Always confirm spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention mechanism per the toolholder manufacturer specification. Inspect the cutting edges for chipping before each use and replace the tool if edge integrity is compromised.
