Iscar 5607686 Milling Insert Rxcu 43-AXT IC808 Carbide

Product Description

The ISCAR 5607686 is a round, double-sided milling insert designed for high-performance metal removal in demanding machining applications. Manufactured from submicron solid carbide and finished with a multilayer PVD coating — TiAlN, AlTiN, and TiN — this insert delivers wear resistance and thermal stability across a wide range of workpiece materials. It belongs to the HELIDO series and carries ANSI and ISO 13399 compliance. The insert measures 0.510 inches in inscribed circle diameter and 0.236 inches thick, with a 0.250-inch corner radius and a maximum depth of cut of 0.255 inches. Six cutting edges and a T-Land cutting edge style make this insert well-suited for productivity-focused milling operations on CNC machining centers.

This insert is intended for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. The AXT chip breaker geometry and negative rake angle support stable cutting action under moderate to heavy chip loads. It is held in place by a screw-type clamping method and is designed for right-hand cutting. Typical applications include face milling, shoulder milling, and contour milling in aerospace, die-mold, and general metalworking environments. Licensed machinists and CNC setup technicians are the primary installers of this insert type.

Key Features

• Submicron solid carbide substrate with multilayer PVD coating: TiAlN, AlTiN, and TiN via Sumotec PVD process
• Six cutting edges per insert — double-sided design maximizes tool life per insert
• Round RXCU insert shape with 0.250-inch corner radius for smooth surface finish and reduced cutting forces
• Negative rake and T-Land edge style provide edge strength for hard and difficult-to-machine materials
• AXT chip breaker geometry supports controlled chip evacuation across multiple material grades
• ANSI and ISO 13399 compliant; compatible with HELIDO H606 FR.50 cutter series

Compatibility

Designed for use with the ISCAR HELIDO H606 FR.50 cutter series. ANSI code H606 RXCU 43-AXT IC808; ISO code H606 RXCU 43-AXT. Insert size code 43.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Before changing inserts, ensure the machine spindle is fully stopped and locked out per applicable machine safety procedures. Use the appropriate Torx or hex key to seat and torque the clamping screw; do not overtighten or undertighten the screw clamp. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure proper contact and runout performance.
