Accupro 12180477 Square End Mill 1 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12180477 is a solid carbide square end mill designed for high-performance milling in ferrous and hardened materials. It features a 1 inch cutting diameter, a 2-3/4 inch length of cut, and four flutes with a 40-degree helix angle. The AlTiN coating delivers elevated heat resistance and extended tool life in demanding dry or high-speed cutting operations. Made from micrograin carbide, this end mill provides the rigidity and edge retention required for precision work. It is a single-end, center-cutting tool with right-hand cutting and right-hand flute direction.

This end mill is suited for milling operations in aerospace, die and mold, and general metalworking applications where tight tolerances and surface finish quality are critical. The variable index geometry reduces chatter and harmonic vibration during aggressive cuts. With a 1 inch shank diameter and 5 inch overall length, it fits standard tool holders used in CNC machining centers. It is intended for use by machinists and tooling professionals on vertical and horizontal milling equipment.

Key Features

• 1 inch cutting diameter with plus 0.000 inch and minus 0.002 inch mill diameter tolerance
• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN coating for high heat resistance and extended tool life in ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Variable index flute spacing reduces vibration and chatter during heavy cuts
• Center-cutting capable for plunge entry and ramping operations

Compatibility

Designed as an OEM-style replacement and standard-fit tooling for CNC machining centers and manual milling machines accepting a 1 inch straight shank with standard tool holders or collet chucks.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Verify that the tool holder bore and collet are clean and free of chips before seating the shank. Confirm runout with a dial indicator after clamping to maintain tolerance and prevent premature tool wear.
