Seco 17007056 Corner Radius End Mill 3/4 in 5 Flute Carbide

Product Description

The SECO 17007056 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding machining environments. Built to Series S545R specifications, it features a 3/4 inch cutting diameter, a 0.0300 inch corner radius, and five flutes with a high 45 degree helix angle. The AlTiN (aluminum titanium nitride) PVD coating provides enhanced heat resistance and wear life when cutting hard, abrasive workpiece materials. Centercutting capability allows plunge entry, and right-hand cutting and flute direction suit conventional CNC milling setups. This tool is intended for use with standard straight-cylindrical toolholders.

This end mill is suited for finishing passes in steel, stainless steel, superalloys, titanium, and other hard materials. Its stub-length configuration and normal pitch make it appropriate for rigid setups where chatter control and surface finish quality are priorities. Machinists and CNC programmers working in aerospace, die and mold, and precision manufacturing will find the S545R series geometry appropriate for tight-tolerance finishing cuts on difficult-to-machine alloys.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating for elevated heat resistance and extended tool life
• 0.0300 inch corner radius with a tolerance of plus 0.00100 to minus 0.00100 inch
• Five-flute, high-helix (45 degree) design optimized for finishing passes
• Centercutting geometry permits direct plunge entry
• Right-hand cut, right-hand spiral flutes; single-end configuration

Compatibility

Designed for use with straight-cylindrical toolholders. Primary workpiece materials are steel, stainless steel, superalloys, titanium, and hard materials (material codes P, M, S, H). No specific machine or toolholder model compatibility was stated in the product data.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before mounting. Confirm runout against the stated TIR maximum of 0.0005 inch after clamping. Follow the toolholder manufacturer torque and retention specifications; do not exceed the recommended overhang for the stub-length configuration.
