Seco 17007052 Corner Radius End Mill 5/8 in 5 Flute Altin

Product Description

The SECO 17007052 is a single-end, solid carbide corner radius end mill built for finishing operations in demanding materials including steel, stainless steel, superalloys, titanium, and hard materials. It carries a 5/8-inch diameter, a 0.1250-inch corner radius, and five flutes arranged in a right-hand spiral with a 45-degree helix angle. The AlTiN PVD coating provides thermal resistance and wear protection during high-temperature cutting. With a 1.625-inch length of cut and a 3.5-inch overall length, this tool fits standard cylindrical toolholders with a 5/8-inch straight shank. It is center-cutting, allowing plunge entry, and is offered as a single piece in the S545R series.

This end mill is intended for finishing passes in CNC machining centers and milling machines where tight surface finish tolerances and controlled corner geometry are required. The S545R series targets applications in steel and high-alloy workpiece materials where heat generation and tool wear are primary concerns. It is suited for both vertical and horizontal machining setups in job shops, aerospace component machining, and precision manufacturing environments. No coolant-through capability means it relies on flood or mist coolant delivered externally, or air blast for chip evacuation.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• AlTiN PVD coating extends tool life in high-temperature cutting of steel, stainless, and superalloys
• 0.1250-inch corner radius reduces stress concentration at the cutting edge and improves surface finish
• Five-flute geometry with 45-degree high helix improves chip flow and finish quality on finishing passes
• Center-cutting design allows direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and flute direction compatible with standard CNC spindle configurations

Compatibility

Designed for use with standard cylindrical toolholders accepting a 5/8-inch straight shank. Compatible workpiece materials include steel, stainless steel, superalloys, titanium, and hard materials as defined by ISO material codes P, M, S, and H.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Seat the 5/8-inch shank fully into the toolholder and torque the retention mechanism to the toolholder manufacturer's specification. Verify runout against the 0.0005-inch maximum TIR specification using a dial test indicator before the first cut. No coolant-through circuit is required, but external coolant or air blast is recommended to manage chip load and heat in the cut zone.
