Accupro 12181726 Square End Mill 3/8 in 2 Flute Carbide Ticn

Product Description

The ACCUPRO 12181726 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for ferrous and non-ferrous cutting. The 0.375-inch diameter cutting face is finished with TiCN (Titanium Carbonitride) coating, which increases surface hardness and reduces friction 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. It is centercutting, allowing direct plunge entry into a workpiece. This tool is sold as a single unit and is intended for use by machinists and tool-and-die professionals on CNC mills and manual knee mills.

This end mill is suited for production and job-shop milling environments where a long-reach, two-flute tool is required. The 1.125-inch length of cut and 3.0-inch overall length make it appropriate for slotting, profiling, and peripheral milling at moderate depths. The right-hand cut, right-hand flute configuration is the standard orientation for conventional and climb milling on most vertical machining centers. It performs well in aluminum, steel, stainless, and hardened alloys where a TiCN-coated carbide substrate is recommended.

Key Features

• Solid micrograin carbide construction provides high rigidity and wear resistance
• TiCN coating increases surface hardness and reduces built-up edge on ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting design enables direct plunge milling without pre-drilling
• Two-flute spiral geometry suited for slotting and full-width cuts
• Long-reach configuration with 1.125-inch LOC and 3.0-inch OAL for deeper cavity work

Compatibility

Designed as a standard 3/8-inch shank square end mill compatible with ER collet chucks, end mill holders, and Weldon-style tool holders accepting a 0.375-inch shank diameter on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the tool holder and torque the retention mechanism per the holder manufacturer specifications. Verify runout with a dial indicator before engaging the cut, as carbide end mills are sensitive to excessive runout which can cause chipping or premature failure.
