Accupro 12183412 Square End Mill 3/8 in 4 Flutes Solid Carbide

Product Description

The ACCUPRO 12183412 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous metals. It features a 3/8 inch diameter cutting face with a 1-3/8 inch length of cut and a 40-degree helix angle that promotes efficient chip evacuation and reduced cutting forces. The TiCN coating adds surface hardness and wear resistance, extending tool life in abrasive or high-heat applications. With a micrograin carbide substrate, it maintains edge integrity under demanding feed and speed conditions. This tool is installed and operated by machinists and CNC programmers in production and job shop environments.

This end mill is suited for slotting, profiling, and pocketing operations where extra reach is required. The extra long overall length of 3 inches combined with the 3/8 inch shank diameter allows access to deeper features without sacrificing rigidity. The right-hand cut and right-hand spiral flute configuration is standard for conventional and climb milling on vertical machining centers and manual knee mills. Centercutting capability allows direct plunge entry without a pre-drilled pilot hole.

Key Features

• Solid micrograin carbide construction for extended tool life and edge retention
• TiCN finish improves hardness and reduces friction at the cutting edge
• 40-degree helix angle promotes aggressive chip evacuation in deep cuts
• Centercutting design allows direct plunge milling without a pilot hole
• Four-flute configuration balances chip clearance with surface finish quality
• Extra long length type provides reach for deep cavity and pocket work

Compatibility

Designed as a standard shank end mill compatible with ER collet chucks, end mill holders, and Weldon-style holders accepting a 3/8 inch shank diameter on vertical machining centers and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator. The machine spindle must be fully stopped and the tool path program verified before tool changes. Seat the shank fully into the holder and torque the retention mechanism per the holder manufacturer specification. Confirm runout with a dial indicator before beginning a production run, as excessive runout will accelerate wear on a carbide tool.
