Titan Usa TC25900 Square End Mill 3/4 in 5 Flute Carbide

Product Description

The TITAN USA TC25900 is a 5-flute solid carbide square end mill designed for high-performance milling in demanding metalworking applications. With a 3/4 inch cutting diameter and 2-1/4 inch length of cut, it handles deep-slot and peripheral milling passes in a single setup. The micrograin carbide substrate provides edge retention and resistance to chipping, while the AlCrO-MAX coating adds thermal and oxidation resistance at elevated cutting speeds. The 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This tool is installed and used by machinists and CNC operators working in job shops, aerospace, die-and-mold, and general precision machining environments.

The TC25900 is suited for milling ferrous and hardened materials where heat generation and tool wear are primary concerns. The variable index geometry reduces harmonic vibration during aggressive cuts. The single-end, right-hand cutting configuration is standard for conventional CNC vertical machining centers and manual knee mills. Center-cutting capability allows direct plunge entry without pre-drilling. Upcut flute geometry directs chips away from the workpiece surface for cleaner finishes.

Key Features

• 5-flute variable-index design reduces chatter and vibration during heavy cuts
• AlCrO-MAX coating provides oxidation and heat resistance for high-speed ferrous milling
• 38-degree right-hand helix promotes positive chip flow and reduced cutting pressure
• Micrograin solid carbide substrate delivers edge stability in hard and abrasive materials
• Center-cutting geometry allows direct plunge milling without a pilot hole
• Single-end construction with matched shank and cutting diameter for rigid toolholding

Compatibility

Designed as an OEM-style solid carbide end mill for use in standard 3/4 inch ER, shrink-fit, or side-lock toolholders on CNC and manual milling machines.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before mounting. Seat the shank fully into the toolholder to the recommended gauge-line depth before tightening. Verify runout with a dial indicator after clamping, as excessive runout will accelerate wear on a multi-flute carbide tool.
