Titan Usa TC58089 Square End Mill 0.089 in 4 Flute Carbide

Product Description

The TITAN USA TC58089 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.0890-inch cutting diameter, a 0.267-inch length of cut, and a 0.125-inch shank diameter, this tool is suited for tight-tolerance slotting, profiling, and contouring passes. The 4-flute, 30-degree helix geometry promotes efficient chip evacuation and a smooth surface finish. The micrograin carbide substrate delivers the rigidity and wear resistance required for consistent performance in production environments. This end mill ships in a bright, uncoated finish and is sold individually.

This end mill is appropriate for use in CNC machining centers and manual mills where small-diameter tooling is required. Typical applications include detail work on dies, molds, and fixtures, as well as fine-feature milling on aluminum, brass, steel, and similar materials. The right-hand cut, upcut flute configuration makes it a standard choice for general-purpose milling in job shop and production settings alike. Machinists and tool-and-die technicians are the primary users of this size range.

Key Features

• 0.0890-inch cutting diameter with 0.267-inch length of cut for fine-feature work
• 4 flutes with a 30-degree helix angle for balanced chip load and surface finish
• Micrograin solid carbide construction for rigidity and extended tool life
• Right-hand cut with upcut flute direction — standard configuration for CNC and manual mill use
• Centercutting capable, allowing direct plunge entry into workpiece
• Bright, uncoated finish — suitable for a wide range of base materials without coating-related limitations

Compatibility

Designed for use in 1/8-inch collets or end mill holders on CNC machining centers and manual vertical mills requiring small-diameter square end tooling.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Use a calibrated torque wrench or collet nut wrench appropriate to the holder style — do not overtighten, as micrograin carbide is brittle and sensitive to clamping stress. Verify runout with a dial indicator after seating to confirm proper tool alignment before beginning a cut.
