Accupro 95168255 Square End Mill 1/2 in 5 Flute Carbide

Product Description

The ACCUPRO 95168255 is a single-end square end mill designed for precision milling operations in metal-cutting applications. Built from micrograin solid carbide and coated with AlTiN (Aluminum Titanium Nitride), this tool delivers strong wear resistance and thermal stability at elevated cutting temperatures. It features a 1/2 inch cutting diameter, a 5/8 inch length of cut, and a 45-degree helix angle across 5 spiral flutes. The right-hand cutting and right-hand flute direction suit standard CNC and manual milling setups. At 2.5 inches overall length with a 1/2 inch shank diameter, it fits a wide range of collet and end mill holders used by machinists and tool-and-die professionals.

This stub-length end mill is intended for slotting, profiling, and peripheral milling on ferrous and hard materials where heat generation is a concern. The AlTiN coating extends tool life when cutting alloy steels, stainless steels, cast iron, and similar hard workpiece materials. The 45-degree helix promotes smooth chip evacuation and reduced cutting forces. It is centercutting, allowing plunge entry as well as conventional side-milling passes. Typical applications include production machining environments, mold and die work, and precision fabrication shops operating CNC machining centers or knee mills.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• AlTiN coating provides oxidation resistance and extends tool life in high-heat cuts
• 5 spiral flutes with 45-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Stub length (5/8 inch LOC, 2.5 inch OAL) minimizes deflection in tight setups
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed as an OEM-style replacement or direct-application solid carbide end mill compatible with standard 1/2 inch collet chucks, shrink-fit holders, and end mill holders used in CNC machining centers and manual milling machines.

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 tool from the holder. Follow the tool holder manufacturer's torque specifications when securing set screws or collet nuts. Verify runout with a dial indicator after seating to confirm proper tool engagement before beginning a cut.
