Titan Usa TC99528 7/16 in 4 Flute Solid Carbide End Mill

Product Description

The TITAN USA TC99528 is a 4-flute solid carbide square end mill designed for precision milling in demanding metalworking and machining applications. With a 0.4375 inch (7/16 inch) cutting diameter and a 1 inch length of cut, this tool delivers accurate, consistent stock removal in ferrous and non-ferrous materials. The micrograin carbide substrate provides rigidity and edge retention, while the AlTiN coating adds heat resistance and extends tool life at elevated cutting speeds. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces across a range of materials and operations.

This end mill is suited for CNC machining centers and manual mills used in job shops, tool rooms, and production environments. The upcut right-hand flute geometry and right-hand cut direction make it a standard configuration for conventional and climb milling of slots, pockets, and profiles. The 0.4375 inch shank diameter matches the cutting diameter, allowing direct clamping in collets or end mill holders without a reduction sleeve. Typical applications include side milling, full-width slotting, and contour work in steel, alloy steel, stainless, aluminum, and similar materials.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• AlTiN coating provides thermal barrier and extended tool life at high cutting speeds
• 4-flute design balances chip load capacity with surface finish quality
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting capable, allowing plunge entry into workpiece material
• Upcut right-hand flute with right-hand cut — standard configuration for broad machine compatibility

Compatibility

Designed as a standard 7/16 inch shank square end mill for use in CNC machining centers and manual knee mills equipped with compatible collet chucks or end mill holders accepting a 0.4375 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the recommended minimum insertion depth in the collet or holder to prevent tool pullout under load. Verify runout with a dial indicator before commencing cuts, as excessive runout accelerates edge wear and reduces surface finish quality.
