Titan Usa TC99816 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The TITAN USA TC99816 is a solid carbide square end mill designed for precision milling in ferrous and high-temperature alloy applications. It features a 1/4 inch diameter cutting face with a 3/4 inch length of cut and a 2.5 inch overall length. Three right-hand flutes with a 30-degree helix angle promote efficient chip evacuation and smooth surface finishes. The AlTiN (aluminum titanium nitride) coating extends tool life in dry and high-speed cutting conditions by reducing heat transfer into the carbide substrate. Micrograin carbide construction provides edge retention under demanding feed rates. This is a single-end, center-cutting tool suited for slot milling, profiling, and plunge cuts.

This end mill is used in CNC machining centers, manual knee mills, and benchtop mills for cutting steel, stainless steel, hardened alloys, and similar materials. The right-hand cutting and upcut flute direction make it a standard choice for conventional and climb milling passes in production shops, tool rooms, and maintenance machining environments. It is sold individually and is well suited to applications where a 1/4 inch shank toolholder or collet is already in use.

Key Features

• 1/4 inch cutting diameter with 3/4 inch length of cut for shallow-to-medium slot and profile work
• AlTiN coating for extended tool life in high-heat and dry-cutting applications
• 3 right-hand upcut flutes with 30-degree helix for efficient chip removal
• Micrograin solid carbide construction for edge retention and rigidity
• Center-cutting geometry allows direct plunge entry into workpiece
• Single-end design with 1/4 inch shank diameter for standard ER and TG collet compatibility

Compatibility

Designed for use in any milling machine or machining center equipped with a 1/4 inch collet or end mill holder. No specific OEM model compatibility was stated in the product data.

Installation Notes

End mills of this type are installed by machinists or CNC operators using a collet chuck or end mill holder torqued to the toolholder manufacturer's specification. Ensure the shank is clean and fully seated before tightening. Verify spindle direction is set to right-hand (clockwise) rotation before engaging the cut. Do not exceed the recommended depth of cut for the flute length, and confirm workpiece fixturing is rigid to prevent chatter and tool deflection.
