Iscar 5600943 Milling Insert Semw 1204AFTN IC250 Carbide

Product Description

The ISCAR 5600943 is a solid carbide milling insert carrying the ISO designation SEMW 1204AFTN and manufactured in the IC250 grade. It features a square insert shape with a 90-degree included angle, four cutting edges, and a neutral hand orientation. The insert is coated via PVD process with a TiCN plus TiN multilayer finish, which supports cutting performance in steel and stainless steel applications. At 0.187 inches thick with a 0.5000-inch inscribed circle and 0.5000-inch cutting edge effective length, this insert is sized for moderate-depth face and shoulder milling operations. It is installed using a screw-holding method and is classified as a single-sided insert with a flat top chip breaker and T-Land cutting edge style.

This insert is intended for use in face milling and shoulder milling operations on steel and stainless steel workpieces, corresponding to ISO material codes P and M. The positive rake geometry and T-Land edge prep reduce cutting forces and help manage heat generation when machining these materials. It is compatible with the ISCARMILL F45ST cutter series. Typical users are CNC machinists and tooling specialists in job shops, production machining, and aerospace or general metalworking environments. The maximum depth of cut is 0.2560 inches.

Compatibility

Designed for use with the ISCARMILL F45ST cutter series. ANSI catalog reference is SEMW 43 AFTN IC250. Verify toolholder pocket specifications against insert dimensions before installation.

Installation Notes

Installation is performed by CNC machinists or tooling technicians using the designated clamping screw for the F45ST cutter body. Ensure the spindle is fully stopped and machine is locked out before indexing or replacing inserts. Seat the insert fully into the pocket and torque the clamping screw to the toolholder manufacturer's specified value using a calibrated torque wrench. Inspect seating surfaces for chips or debris before securing the insert.
