Accupro 310316 Square End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 310316 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. It features a 0.5-inch cutting diameter, a 1.625-inch length of cut, and four spiral flutes with a 38-degree helix angle for aggressive chip evacuation and smooth finishes. The AlTiCrN coating provides high heat resistance and extended tool life in demanding cutting conditions. The micrograin carbide substrate adds toughness and edge retention. This tool is used by machinists and tool-and-die professionals in CNC milling applications where tight tolerances and surface finish are critical.

The 310316 is suited for peripheral and slot milling in ferrous and non-ferrous metals, stainless steels, and hardened alloys. The single-end configuration with a 0.5-inch shank diameter makes it compatible with standard ER collet chucks and end mill holders used in vertical machining centers and CNC mills. The right-hand cut and right-hand flute direction support conventional climb-milling setups. Variable index spacing reduces harmonic chatter during high-speed passes. The Series HS designation indicates it is optimized for high-speed machining strategies.

Key Features

• 0.5-inch cutting diameter with 1.625-inch length of cut for deep slot and peripheral milling
• AlTiCrN coating for high-temperature resistance and extended tool life in hard materials
• 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Micrograin solid carbide construction for edge retention and dimensional stability
• Variable index flute spacing reduces vibration and chatter during high-speed cuts
• Center-cutting capable, allowing plunge entry without a pre-drilled pilot hole

Compatibility

Designed for use in standard 0.5-inch end mill holders, ER collet chucks, and shrink-fit tooling systems on CNC vertical machining centers and manual knee mills. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully powered down and locked out before inserting or removing the end mill from the tool holder. Verify that the shank is fully seated to the recommended gauge-line depth in the holder to prevent pull-out under cutting loads. Follow the tooling manufacturer and machine builder guidelines for recommended speeds and feeds based on material and depth of cut.
