Seco 17007006 Corner Radius End Mill 3/8 in 5 Flute Altin

Product Description

The SECO 17007006 is a solid carbide corner radius end mill designed for high-performance finishing in demanding machining environments. It features a 3/8 inch (0.3750 inch) mill diameter, a 0.0450 inch corner radius, and five flutes with a right-hand spiral and high helix geometry. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting ferrous and exotic 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 on tight-tolerance finishing passes. It is centercutting and accepts standard straight-cylindrical toolholders.

This end mill is suited for finishing operations on steel, stainless steel, superalloys, titanium, and other hard materials. The stub-length configuration makes it a practical choice for milling pockets, slots, and contoured profiles where reach is limited and rigidity is critical. It is part of the SECO S545R series, which targets high-hardness and difficult-to-machine workpiece materials in both production and job-shop environments. A licensed machinist or CNC tooling technician would typically select this tool for semifinish to finish passes requiring precise corner geometry control.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN PVD coating enhances heat resistance and tool life in steel, stainless steel, superalloys, and titanium
• 0.0450 inch corner radius reduces stress concentration and improves surface finish at part edges
• Five-flute, high-helix right-hand spiral geometry optimized for finishing passes
• Centercutting design allows plunge entry and versatile toolpath options
• Stub-length (1/2 inch LOC) configuration maximizes rigidity and minimizes deflection

Compatibility

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

Installation Notes

Installation is performed by a qualified CNC machinist or tooling technician. Confirm that the toolholder bore is clean and within tolerance before seating the 3/8 inch straight-cylindrical shank. Verify runout does not exceed the 0.0005 inch TIR maximum specification before beginning a cut. Follow the machine tool manufacturer and SECO speed and feed recommendations for the specific workpiece material and coating type.
