Seco 02881043 High-feed End Mill 1-1/4 in 1/2 in Shank

Product Description

The SECO 02881043 is an indexable high-feed end mill designed for high-feed milling operations in metal cutting and machining applications. The tool accepts 2 LPHT-style indexable inserts and delivers a maximum cutting diameter of 1.25 inches with a maximum depth of cut of 0.025 inches per pass. The 0.5-inch cylindrical shank provides a secure connection to compatible toolholders. With an overall length of 5 inches and a functional length of 1.6 inches, this end mill is well-suited for high-speed material removal where chip load efficiency and insert accessibility are priorities. Rated to 19,700 RPM, it is intended for use by machinists and CNC operators in production and job-shop environments.

This end mill belongs to the SECO High Feed 2-05 series and uses the R217.21 toolholder style. It is intended for milling operations on ferrous and non-ferrous materials in both vertical and horizontal machining center setups. The maximum ramping angle of 3.73 degrees allows for helical entry or plunge ramping where the application permits. The 2-insert configuration is appropriate for smaller diameter high-feed work where balance and insert load distribution are critical to tool life and surface finish.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Secure the cylindrical shank fully in the toolholder to the manufacturer-specified engagement depth before operation. Verify spindle speed does not exceed the 19,700 RPM maximum rating. Confirm insert seating and torque fasteners per the insert manufacturer guidelines before beginning a cut.
