Titan Usa TC99525 Square End Mill 0.3906 in 4 Flute Altin

Product Description

The TITAN USA TC99525 is a solid carbide square end mill designed for precision material removal in milling operations. It features a 0.3906 inch (25/64 inch) cutting diameter, a 1 inch length of cut, and a 0.4375 inch (7/16 inch) shank diameter, with an overall length of 2.75 inches. The four-flute, right-hand cut geometry combines with a 30-degree helix angle and an AlTiN coating to handle demanding cuts in ferrous and non-ferrous metals. The micrograin carbide substrate provides edge retention and resistance to chipping under high-feed conditions. This tool is sold as a single end mill and packaged individually.

This end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills where tight tolerances and clean sidewall finishes are required. The upcut, right-hand flute direction promotes chip evacuation away from the workpiece, making it appropriate for slotting, profiling, and peripheral milling operations in steel, stainless steel, cast iron, and similar materials. The AlTiN coating extends tool life in high-temperature cutting environments. Machinists and toolroom technicians working in job shops, production facilities, and maintenance environments are the primary users of this tool.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• AlTiN coating provides heat resistance and extended tool life in ferrous metals
• 30-degree helix angle balances cutting force and chip evacuation
• Four-flute design supports higher feed rates and improved surface finish
• Upcut right-hand flute direction clears chips away from the cut zone
• Centercutting capability allows plunge entry into the workpiece

Compatibility

Designed as a standard straight-shank square end mill compatible with ER collet chucks, end mill holders, and other 7/16 inch shank tool-holding systems used on CNC and manual milling machines.

Installation Notes

Installation is performed by machinists using appropriate tool holders rated for the 0.4375 inch shank diameter. Ensure the tool holder and spindle are clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping to avoid premature tool wear or dimensional error. Follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material and depth of cut.
