Description

The SECO 00023612 is a solid carbide milling insert carrying the ANSI/ISO designation APEX160408FR-E08, part of the APEX-16 series. It features a parallelogram shape with an 85-degree included angle, a positive rake angle of 25 degrees, and a sharp cutting edge style suited for aggressive chip evacuation in non-ferrous metal applications. The insert is uncoated micrograin carbide in manufacturer grade H15, offering a 0.375-inch inscribed circle, a thickness of 0.1874 inches, and two cutting edges. It is held in the cutter body by a screw and is designed for right-hand cutting. Licensed machinists and CNC tooling technicians are the primary installers of this insert type.

This insert is intended for milling non-ferrous metals such as aluminum, copper alloys, and similar materials where a sharp, uncoated carbide edge delivers clean surface finish and reduced built-up edge. The E08 chip breaker geometry supports efficient chip flow at the depths of cut and feed rates typical for high-speed face and shoulder milling operations. It fits cutter bodies in the R217.69-16 and R220.69-16 series. The positive rake and sharp edge make it well suited for finishing and semi-finishing passes on non-ferrous workpieces in both production and job-shop environments.

Key Features

Solid carbide micrograin construction in H15 grade for non-ferrous metal cutting
Uncoated bright finish eliminates built-up edge risk on aluminum and copper alloys
Positive 25-degree rake angle with sharp cutting edge for reduced cutting forces
E08 chip breaker geometry supports effective chip evacuation
Two cutting edges per insert for extended tooling economy
Screw-clamp insert holding for secure, repeatable seating in compatible cutter bodies

Compatibility

Compatible with SECO cutter series R217.69-16 and R220.69-16. Insert size code 160408 with ANSI/ISO designation APEX160408FR-E08. Sold individually; minimum order quantity is 10 units.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the spindle locked and machine power isolated per facility lockout/tagout procedures. Use the manufacturer-specified torx or hex key to seat the clamping screw to the cutter body specification do not overtighten, as this can fracture the carbide insert. Inspect the insert pocket and screw for wear or debris before seating a new insert. Always verify insert orientation and hand designation match the cutter body before resuming operation.
