Seco 02881817 Square End Mill 0.3937 in 3 Flute Carbide

Product Description

The SECO 02881817 is a solid carbide square end mill designed for precision milling operations in non-ferrous metal applications. Part of the SECO JS413 series, this single-end mill features a 0.3937 inch cutting diameter, a 1.5748 inch length of cut, and a 3-flute spiral geometry with a 40-degree helix angle. The right-hand cut, right-hand flute configuration delivers efficient chip evacuation and stable cutting action. Micrograin carbide construction provides edge retention in demanding machining environments. This tool is intended for use by machinists and CNC operators working in production or job shop settings.

The 02881817 is suited for milling non-ferrous metals such as aluminum, brass, and copper alloys where a high-helix, centercutting end mill is preferred. The extended length-of-cut design supports deeper slotting and profiling passes without requiring a tool change. The straight-cylindrical shank with h5 tolerance ensures consistent runout in standard collet and end mill holders. This tool fits the extended length classification and is appropriate for applications where standard-length reach is insufficient.

Key Features

• 0.3937 inch cutting diameter with e8 tolerance for precise fit and finish
• 1.5748 inch length of cut supports deep slotting and full-depth profiling
• 3-flute spiral geometry with 40-degree helix angle optimized for non-ferrous materials
• Centercutting design allows direct plunge entry into workpiece
• Micrograin solid carbide construction for edge retention and wear resistance
• Bright/uncoated finish suitable for aluminum and other non-ferrous applications

Compatibility

Designed as an OEM-style replacement end mill for use in CNC machining centers and manual mills accepting a 0.3937 inch straight-cylindrical shank. Primary workpiece material class is non-ferrous metal (ISO material code N/O).

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the collet or end mill holder to the recommended grip length before tightening. Confirm tool runout with a dial indicator before initiating the cut. Always power down and lock out the spindle before changing tooling.
