Accupro 12181413 Square End Mill 3/8 in 2 Flute Carbide

Product Description

The ACCUPRO 12181413 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining applications. With a 0.375-inch mill diameter and a 40-degree helix angle, this two-flute, right-hand cut tool delivers efficient chip evacuation and clean shoulder milling. The TiCN (titanium carbonitride) coating increases surface hardness and reduces friction at the cutting edge, extending tool life in ferrous and non-ferrous materials. The micrograin carbide substrate provides rigidity and wear resistance. This tool is installed and used by machinists, tool-and-die workers, and CNC operators across job shops and production environments.

This end mill is suited for slot milling, profiling, and plunging operations in a wide range of workpiece materials. The centercutting geometry allows direct plunge entry without a pre-drilled hole. With a 0.875-inch length of cut (LOC) and a 2.5-inch overall length (OAL), the regular-length profile keeps tool deflection low in standard-depth applications. The 0.375-inch shank diameter matches common collet and end mill holder sizes used on vertical machining centers and manual knee mills.

Key Features

• 0.375-inch mill diameter with tight tolerance of +0.000 / -0.002 inches for accurate dimensional milling
• TiCN finish for improved hardness and reduced built-up edge in demanding cuts
• 40-degree spiral helix promotes smooth cutting action and effective chip clearing
• Centercutting design enables direct plunge milling without pre-drilling
• Micrograin solid carbide construction for high rigidity and extended tool life
• Right-hand cut, right-hand flute configuration compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 3/8-inch collets and end mill holders on vertical machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before loading or unloading the tool. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut to avoid premature tool wear or workpiece damage.
