Seco 17007002 Corner Radius End Mill 3/8 in 5 Flute Altin

Product Description

The SECO 17007002 is a solid carbide corner radius end mill engineered for high-performance finishing operations in demanding materials. It features a 3/8 inch diameter, a 0.0150 inch corner radius, and five flutes arranged in a right-hand spiral with a 45-degree high helix angle. The AlTiN PVD coating provides thermal resistance and wear protection when cutting steel, stainless steel, superalloys, titanium, and hard materials. At 2 inches overall length with a 1/2 inch length of cut, this is a stub-length tool built for rigidity and reduced deflection. It is centercutting and accepts standard straight-cylindrical toolholders. Machinists and tool-and-die professionals working in job shops, aerospace, and precision manufacturing will recognize this as a finishing-grade carbide end mill suited to tight-tolerance work.

The 17007002 is designed for finishing passes in steel, stainless steel, superalloys, titanium, and hard materials (ISO material codes P, M, S, H). The stub length format makes it well-suited for applications where overhang must be minimized to maintain dimensional accuracy. It seats in standard straight-cylindrical toolholders and is compatible with CNC machining centers and manual mills where a 3/8 inch straight shank is accepted. The corner radius geometry reduces stress concentration at the cutting edge, extending tool life compared to sharp-corner end mills in the same material class.

Key Features

• Solid carbide construction for maximum rigidity and edge retention in hard and abrasive workpiece materials
• AlTiN PVD coating provides elevated-temperature hardness and oxidation resistance for dry or semi-dry cutting
• Five-flute, high-helix (45 degrees) design improves chip evacuation and surface finish in finishing operations
• 0.0150 inch corner radius reduces edge chipping and stress concentration at the tool tip
• Centercutting capability allows plunge entry without a pre-drilled hole
• Stub length format (1/2 inch LOC, 2 inches OAL) maximizes tool rigidity and minimizes deflection

Compatibility

Designed for use with standard straight-cylindrical toolholders accepting a 3/8 inch shank diameter. Suited for CNC machining centers performing finishing operations in steel, stainless steel, superalloys, titanium, and hard materials as part of the SECO S545R series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the toolholder bore and shank are clean and free of chips or burrs before seating the end mill. Verify runout against the specified TIR maximum of 0.0005 inch after clamping. Follow machine tool manufacturer torque recommendations for the collet or set-screw toolholder in use.
