Seco 17003160 Square End Mill 1/2 in 3 Flute Carbide A345

Product Description

The SECO 17003160 is a solid carbide square end mill designed for high-precision material removal in aluminum and non-ferrous metal applications. Built to Series A345 specifications, it features a 0.5 inch mill diameter, a 45-degree helix angle, and a micrograin carbide substrate that supports sharp cutting edges and tight tolerances. The bright, uncoated finish is well suited for non-ferrous materials where coating adhesion or aluminum pickup could be a concern. This is a single-end, center-cutting tool, meaning it can be used for both peripheral milling and plunge operations. It is installed and operated by machinists and CNC operators in job shops, production environments, and maintenance machining applications.

This end mill is optimized for cutting aluminum, brass, copper, and other non-ferrous materials where material code N applies. The stub-length classification and 0.625 inch length of cut provide rigidity in short-reach setups, reducing deflection during aggressive feed rates. The straight shank fits standard collet chucks and end mill holders with a 0.5 inch bore. Right-hand cut and right-hand flute geometry follow conventional CNC milling conventions for typical spindle rotation.

Key Features

• 45-degree helix angle promotes efficient chip evacuation in aluminum and non-ferrous materials
• Center-cutting design allows direct plunge entry without a pre-drilled hole
• Micrograin solid carbide substrate for edge sharpness and wear resistance
• Bright, uncoated finish reduces built-up edge when machining aluminum
• Stub-length body (0.625 inch LOC) maximizes rigidity in short-reach applications
• Right-hand cut, right-hand spiral flute geometry for standard CNC spindle direction

Compatibility

Designed for use in standard 0.5 inch collet chucks, end mill holders, and shrink-fit tooling systems. Primary workpiece material designation is aluminum and non-ferrous (material code N). Part of the SECO Series A345 end mill family.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or quill is locked before installing or removing the tool. Seat the straight shank to the full recommended engagement depth in the holder and torque the collet nut or set screw to the toolholder manufacturer specifications. Verify runout against the TIR maximum of 0.0005 inches before beginning any cut.
