Seco 17007063 Corner Radius End Mill 3/4 in 5 Flute Altin

Product Description

The SECO 17007063 is a solid carbide corner radius end mill designed for finishing operations in demanding materials. It features a 3/4 inch diameter, a 0.0300 inch corner radius, and five right-hand spiral flutes with a 45-degree high helix angle. The AlTiN PVD coating improves heat resistance and tool life when cutting steel, stainless steel, superalloys, and titanium. With a 1-5/8 inch length of cut and 4 inch overall length, it fits standard toolholders with a 3/4 inch straight cylindrical shank. It is centercutting and single-end. Machinists and tool-and-die professionals use this end mill for tight-tolerance finishing passes where corner geometry and surface finish are critical.

This end mill is suited for finishing applications in CNC machining centers handling steel, stainless steel, superalloys and titanium, and hard materials. The short flute length and high helix geometry reduce chatter and improve chip evacuation in difficult-to-machine workpiece materials. It belongs to the SECO S545R series and accepts standard cylindrical toolholders. It is well suited for mold, die, aerospace, and precision machining environments where corner radius integrity and dimensional control are required.

Key Features

• 0.0300 inch corner radius with tolerance of plus or minus 0.00100 inch for consistent part geometry
• AlTiN PVD coating extends tool life in high-temperature cutting of steel, stainless steel, superalloys, and titanium
• Five-flute, high helix spiral design optimized for finishing and smooth surface finish
• Centercutting capability allows plunge entry as well as peripheral and slot milling
• Solid carbide construction provides rigidity and wear resistance in hard and abrasive workpiece materials
• Right-hand cut and right-hand flute direction for use with standard CNC spindle rotation

Compatibility

Designed for use with standard cylindrical toolholders. Part of the SECO S545R series. Primary workpiece materials include steel, stainless steel, superalloys and titanium, and hard materials (material codes P, M, S, H).

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool is secured in a clean, properly sized toolholder before tightening. Verify runout against the stated TIR maximum of 0.0005 inch after seating the tool. Follow shop safety procedures and machine manufacturer guidelines when setting tool offsets and beginning finishing passes.
