Accupro 12181557 Square End Mill 0.7874 in 2 Flute Carbide

Product Description

The ACCUPRO 12181557 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.7874-inch mill diameter and a 1.4961-inch length of cut, this tool delivers accurate material removal in a regular-length profile. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. The micrograin carbide construction provides edge retention and dimensional stability under demanding cutting conditions. This end mill is intended for use by machinists and tooling professionals working on CNC mills, vertical machining centers, and manual knee mills.

This end mill suits a wide range of machining applications including slotting, profiling, and peripheral milling in shop and production environments. The centercutting design allows for plunge entry, expanding versatility for pocketing operations. Right-hand cut and right-hand flute geometry is standard for conventional CNC and manual mill setups. The uncoated finish makes this tool well-suited for use with cutting fluids in aluminum, brass, plastics, and softer steels where coating adhesion is not required.

Key Features

Compatibility

Designed as a standard-shank square end mill for use in collet chucks, end mill holders, and shrink-fit tooling systems accepting a 20.00 mm (0.7874-inch) shank diameter on CNC and manual milling equipment.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Verify shank engagement depth meets the tool holder manufacturer minimum before tightening. Confirm runout with a dial indicator after installation to maintain dimensional accuracy and maximize tool life.
