Titan Usa TC74677 Corner Radius End Mill 1in 4 Flute Altin

Product Description

The TITAN USA TC74677 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining applications. The tool features a 1 inch cutting diameter, a 4 inch length of cut, and a 0.06 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. An AlTiN (aluminum titanium nitride) PVD coating improves hardness and heat resistance at elevated cutting temperatures. Four right-hand spiral flutes with a medium helix angle provide a balance of chip evacuation and surface finish. The TC74677 is a single-end, straight-shank tool intended for use in CNC machining centers with compatible toolholders.

This end mill is suited for roughing and finishing operations on superalloys, titanium alloys, stainless steel, cast iron, alloy steel, and Inconel. The extra-long length of cut and 7 inch overall length make it appropriate for deep-pocket milling, profiling, and contouring where standard-length tools cannot reach. It is commonly used in aerospace, die and mold, and precision manufacturing environments where difficult-to-machine materials are the norm.

Key Features

• AlTiN PVD coating for heat resistance in high-temperature alloy and stainless steel cutting
• 0.06 inch corner radius reduces edge chipping and improves tool life at the cutting corner
• Extra-long 4 inch length of cut enables deep-pocket and long-reach machining
• Four right-hand spiral flutes with medium helix for balanced chip flow in roughing and finishing
• Solid carbide construction provides rigidity and wear resistance over HSS alternatives
• Straight cylindrical shank with h6 shank diameter tolerance for precise toolholder fit

Compatibility

Designed for use with standard CNC toolholders that accept a 1 inch straight cylindrical shank. Primary workpiece materials include superalloys, titanium alloys, stainless steel, cast iron, alloy steel, and Inconel.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or unloading the tool. Seat the shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before cutting; excessive runout accelerates corner wear on radius end mills. Do not use this tool for aluminum or non-ferrous applications without confirming coating suitability.
