Titan Usa TC74654 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The TITAN USA TC74654 is a solid carbide corner radius end mill designed for demanding material removal in ferrous metals, superalloys, titanium alloys, stainless steel, and cast iron. It carries a 3/4 inch (0.7500 inch) mill diameter with a 0.0300 inch corner radius, four right-hand spiral flutes, and an AlTiN (aluminum titanium nitride) PVD coating that supports high-heat cutting environments. The extra-long length type provides 3.0000 inches of reach length and a 6 inch overall length, making it well suited for deep-pocket and extended-reach milling operations. This tool handles both roughing and finishing passes in a single setup.

The TC74654 is used in CNC machining centers and manual mills where extended reach into deep pockets, slots, or profiles is required. Its 30-degree helix and normal pitch geometry suit general milling operations on superalloys, Inconel, alloy steel, stainless steel, and titanium alloy workpieces. The straight-cylindrical shank seats in standard toolholders. This end mill is a single-end tool and is sized for production shops, aerospace component machining, and precision job shops cutting difficult materials.

Key Features

• AlTiN PVD coating improves wear resistance and thermal performance in high-temperature alloy cutting
• 0.0300 inch corner radius reduces stress concentration at the cutting edge and extends tool life
• 3.0000 inch reach length supports deep-pocket milling without secondary tooling
• Solid carbide construction provides rigidity and edge retention in ferrous and hard materials
• Right-hand cut, right-hand flute spiral with normal pitch for stable chip evacuation
• Rated for roughing and finishing material removal in a single tool

Compatibility

Designed for use with standard cylindrical toolholders accepting a 3/4 inch straight shank. Suitable for machining superalloys, titanium alloy, Inconel, stainless steel, alloy steel, and cast iron workpieces per UNSPSC code 27112803.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Seat the straight-cylindrical shank fully into the toolholder and torque the retention system per the toolholder manufacturer specifications. Confirm spindle direction matches the right-hand cut orientation before running. Do not exceed the toolholder or spindle rated RPM for this diameter, and verify workpiece fixturing rigidity before initiating cuts in hard or high-temperature alloys.
