Titan Usa TC54665 Square End Mill 0.5 Mm 3 Flute Carbide

Product Description

The TITAN USA TC54665 is a square end mill designed for precision milling in tight-tolerance applications. Built from solid carbide micrograin material, it cuts a 0.5 mm diameter path with three flutes and a 30-degree helix angle. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern. At 2.5 inches overall length with a 0.125-inch shank, this single-end tool fits standard collet chucks used in CNC machining centers and high-speed spindles. Center-cutting geometry allows plunge entry as well as peripheral cuts. Machinists and CNC operators working in prototype shops, tool rooms, and production environments are the primary users.

This end mill is suited for fine-detail milling on small-scale features in ferrous and non-ferrous materials. The extended reach configuration and 0.3-inch reach length make it capable of accessing recessed floors and narrow pockets without tool interference. The right-hand cut and right-hand flute direction are standard for conventional CNC vertical milling setups. A length of cut range of 0.1 to 0.2 inches keeps the tool rigid at this micro diameter, reducing deflection during aggressive passes.

Key Features

• 0.5 mm (0.0200 inch) cutting diameter for micro-scale milling work
• 3-flute, solid carbide micrograin construction for rigidity and edge retention
• 30-degree helix angle with upcut flute direction for efficient chip evacuation
• Center-cutting design allows direct plunge entry into the workpiece
• Extended reach with 0.3-inch reach length for accessing deep or recessed features
• Bright/uncoated finish — no coating interaction with sensitive workpiece materials

Compatibility

Designed for use in CNC machining centers and high-speed spindles accepting a 0.125-inch (1/8 inch) shank diameter via standard collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with micro-diameter tooling. Ensure the spindle and collet bore are clean and free of debris before seating the shank to the correct engagement depth. At 0.5 mm diameter, this tool is highly susceptible to breakage from side-load shock, improper runout, or excessive feed rates — verify collet concentricity and program feeds and speeds appropriate for the workpiece material before running. Power down the machine and lock out the spindle before changing tooling.
