Accupro 12181756 Square End Mill 3/8 Inch 2 Flute Carbide

Product Description

The ACCUPRO 12181756 is a solid carbide square end mill designed for precise milling operations in metal and composite materials. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for demanding cuts. The TiCN (Titanium Carbonitride) coating reduces friction and improves wear resistance at the cutting edge. With a 40-degree helix angle and spiral flute geometry, this end mill promotes efficient chip evacuation and smooth cutting action. The centercutting design allows both plunge and peripheral milling. It measures 0.375 inches in diameter with a 1.75-inch length of cut and a 4.0-inch overall length, placing it in the extra-long category for extended reach applications.

This end mill is suited for milling operations where standard-length tooling cannot reach the workpiece. The extra-long OAL makes it appropriate for deep pocket milling, stepped-feature machining, and setups requiring clearance from fixtures or clamps. It is installed in machining centers, CNC mills, and manual knee mills by machinists and tooling technicians. Right-hand cut and right-hand flute configuration is standard for conventional and climb milling on these platforms.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• TiCN coating for reduced friction and extended tool life
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting design allows plunge and peripheral milling
• Extra-long 4.0-inch OAL for extended reach applications
• Right-hand cut and right-hand flute for standard milling setups

Compatibility

Designed as a direct-fit replacement or new installation for standard 3/8-inch tool holders, collets, and milling chucks used in CNC and manual milling machines accepting right-hand, spiral-flute solid carbide end mills.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing tooling. Seat the shank fully and evenly in the collet or tool holder to the recommended gauge-line depth, and torque the collet nut per the tool holder manufacturer specification. Inspect the shank and cutting edges for damage before use; do not run a chipped or cracked carbide tool.
