Accupro 12176632 Square End Mill 7/16 in 3 Flute Carbide

Product Description

The ACCUPRO 12176632 is a solid carbide square end mill designed for precision material removal in milling operations. Built from micrograin carbide with an AlTiN (aluminum titanium nitride) finish, this tool delivers high wear resistance and heat tolerance in demanding cutting environments. The 7/16-inch diameter cutter features three spiral flutes at a 40-degree helix angle, balancing chip evacuation with cutting stability. With a 2-inch length of cut and 4-inch overall length, it is classified as a long-reach end mill, giving machinists access to deeper pockets and features that standard-length tools cannot reach. Licensed machinists and CNC operators install this type of tooling in vertical and horizontal machining centers.

This end mill is suited for ferrous and non-ferrous metal cutting applications in both job shop and production environments. The centercutting geometry allows plunge milling as well as conventional peripheral and slot milling. The right-hand cut and right-hand flute configuration make it compatible with standard spindle rotation on most machining centers and manual mills. The long flute length and AlTiN coating make it a practical choice for stainless steel, alloy steel, and hardened materials where heat generation is a concern.

Key Features

• 7/16-inch (0.4375 inch) mill diameter with tight tolerance of +0.000/-0.002 inches
• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN finish for extended tool life in high-heat cutting applications
• 40-degree helix spiral flute promotes smooth chip evacuation
• Centercutting design enables plunge entry without a pre-drilled hole
• Long flute length (2 inches LOC) for deep pocket and feature access

Compatibility

Designed as a standard-shank replacement end mill for use in machining centers, CNC mills, and manual milling machines accepting a 7/16-inch straight shank with collet or end mill holder tooling.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The shank should be seated securely in a collet or end mill holder to the recommended engagement depth before tightening. Inspect the tool and holder for runout before beginning a cut. Always bring the spindle to a complete stop before changing or adjusting tooling.
