Product Description
The SECO 17007014 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding machining environments. Built on the S545R series platform, it features a 7/16 inch (0.4375 inch) cutting diameter, a 0.0300 inch corner radius, and a 5-flute geometry with a 45-degree high helix angle. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting hard and abrasive workpiece materials. At 2.5 inches overall length with a 9/16 inch length of cut, this is a stub-length tool optimized for rigidity and minimal deflection during finishing passes. It is a single-end, centercutting design with right-hand flute direction and right-hand cutting direction.
This end mill is suited for finishing cuts on steel, stainless steel, superalloys, titanium, and hard materials. The stub-length profile and high helix make it a strong choice for close-tolerance work in CNC machining centers and mill-turn setups where surface finish and edge quality are critical. The straight-cylindrical shank interfaces directly with standard toolholders across common collet and end mill holder systems. It is appropriate for shops running production or precision work in aerospace, medical, die-mold, and general metalworking applications.
Key Features
- 0.0300 inch corner radius with tolerance of +0.001 to -0.001 inch for consistent edge geometry
- 5-flute spiral configuration with normal pitch for smooth chip evacuation during finishing
- AlTiN PVD coating rated for steel, stainless steel, superalloys, titanium, and hard material applications
- 45-degree high helix angle reduces cutting forces and improves surface finish quality
- Centercutting design allows plunge entry without pre-drilling
- Solid carbide substrate for maximum rigidity in stub-length geometry
Compatibility
Designed for use with standard end mill toolholders. Compatible workpiece materials include steel, stainless steel, superalloys, titanium, and hard materials per SECO S545R series application data. UNSPSC Code: 27112803.
Installation Notes
Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Seat the shank fully in the toolholder to the recommended gauge line and confirm runout does not exceed the 0.0005 inch TIR maximum before initiating a cut. Follow the toolholder manufacturer torque and clamping specifications for the collet or set screw style in use.
