Accupro 311367 Square End Mill 1/8 in 5 Flute Solid Carbide

Product Description

The ACCUPRO 311367 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 1/8 inch cutting diameter and five flutes, this tool delivers high material removal rates while maintaining surface finish quality. The 38-degree helix angle promotes smooth chip evacuation and reduces cutting forces across a range of workpiece materials. An AlTiCrN coating provides thermal resistance and hardness at elevated temperatures, making the 311367 well suited for hard materials, dry cutting, and high-speed machining applications. Machinists and CNC operators in job shops and production environments are the primary users of this tool.

This end mill is appropriate for milling operations on ferrous and non-ferrous metals, hardened steels, and similar materials where a high-performance coated carbide tool is required. The 3/4 inch length of cut supports slotting, profiling, and peripheral milling in shallow to medium-depth features. The 1/8 inch shank diameter fits standard collets and toolholders configured for that size. It is a single-end tool from the ACCUPRO HS series, intended for CNC machining centers and manual mills with appropriate spindle speeds and feeds for the diameter.

Key Features

• AlTiCrN coating for high heat resistance and extended tool life in hard and abrasive materials
• Five-flute design increases feed rates and improves surface finish compared to standard four-flute tools
• 38-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Variable index flute spacing reduces chatter and vibration during milling
• Micrograin solid carbide substrate provides rigidity and wear resistance at small diameters
• Centercutting geometry allows plunge entry into the workpiece

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines using 1/8 inch collets or toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and the machine is in a safe state before inserting or removing tooling. Seat the 1/8 inch shank fully and evenly in a clean, undamaged collet or end mill holder and tighten to the toolholder specification. Verify runout with a dial indicator before beginning a production cut, as runout at this diameter has a significant effect on tool life and surface finish.
