Accupro 12181422 Square End Mill 3/8 in 2 Flute Carbide Altin

Product Description

The ACCUPRO 12181422 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 3/8 inch cutting diameter and a 7/8 inch length of cut, this end mill delivers consistent material removal in ferrous and non-ferrous applications. The micrograin carbide substrate provides the rigidity and edge retention needed for demanding cuts. An AlTiN coating enhances heat resistance and wear life, making this tool well suited to higher-speed dry or semi-dry machining. It is installed and operated by machinists and CNC programmers working with milling machines and machining centers.

This end mill fits standard milling applications requiring a 3/8 inch shank and a regular-length tool profile. The 2-flute configuration supports efficient chip evacuation in slotting and peripheral milling operations. A 40-degree helix angle improves cutting action and surface finish on a range of workpiece materials. The right-hand cut and right-hand flute orientation is the conventional setup for the majority of vertical and horizontal milling machines. Centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled pilot hole.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN coating for elevated heat resistance and extended tool life
• 40-degree helix angle promotes smooth cutting action and improved surface finish
• Centercutting design permits direct plunge milling without pre-drilling
• 2-flute spiral geometry aids chip clearance in slotting and profiling cuts
• Right-hand cut and right-hand flute for standard milling machine spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard milling machine and machining center toolholders accepting a 3/8 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Secure the shank fully into the toolholder collet or end mill holder, ensuring the shank is seated to the recommended engagement depth before tightening. Verify spindle rotation direction matches the right-hand cut orientation of this tool before starting the machine. Inspect the cutting edges and coating condition prior to each use and replace the tool if chipping or excessive wear is present.
