Titan Usa TC99524 Square End Mill 3/8 in 4 Flute Carbide

Product Description

The TITAN USA TC99524 is a 4-flute solid carbide square end mill designed for precision milling of ferrous and non-ferrous materials. It features a 3/8-inch cutting diameter with a 1-inch length of cut and a 2.5-inch overall length. The AlTiN (aluminum titanium nitride) coating extends tool life in high-heat applications by reducing friction and improving hardness at elevated temperatures. The micrograin carbide substrate provides rigidity and edge retention. This end mill is sold as a single unit and is used by machinists and tool-and-die professionals in CNC and manual milling applications.

This end mill suits general-purpose slotting, profiling, and peripheral milling operations on a wide range of workpiece materials. The 30-degree helix angle and upcut flute geometry promote efficient chip evacuation, reducing heat buildup at the cutting edge. The centercutting design allows direct plunge entry into the workpiece. The right-hand cut and right-hand flute configuration match standard CNC spindle rotation. Typical applications include job shop machining, mold and die work, and production part milling in both vertical and horizontal machining centers.

Key Features

• Solid micrograin carbide construction for rigidity and extended edge retention
• AlTiN coating for high-heat performance and reduced tool wear
• 4 flutes with upcut geometry for efficient chip evacuation
• 30-degree helix angle balances cutting force and surface finish
• Centercutting design enables direct plunge milling
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 3/8-inch straight shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the collet or tool holder. Seat the shank to the recommended grip depth per the tool holder specification and torque the collet nut per the holder manufacturer guidelines. Verify runout with a dial indicator before beginning the cut to prevent premature tool failure.
