Iscar 5604601 Milling Insert Onmu 080608-TN-MM IC928

Product Description

The ISCAR 5604601 is a solid carbide milling insert carrying the manufacturer part designation ONMU 080608-TN-MM in grade IC928. It features an octagonal shape with a neutral hand orientation, a negative rake geometry, and a T-Land cutting edge style. The insert is coated with TiAlN via a PVD process, delivering wear resistance suited to demanding milling operations. With 16 cutting edges available on a double-sided body, it offers extended tool life per insert. A corner radius of 0.0315 inches (0.80 mm) and a maximum depth of cut of 0.2170 inches (5.50 mm) define its cutting envelope. Licensed machinists and CNC toolroom technicians are the primary installers and users of this insert.

This insert is designed for milling steel, stainless steel, superalloys, and titanium, covering ISO material codes P, M, and S. It belongs to the 16MILL series and is compatible with ISCAR cutter bodies in the F45NM and F45WG series. Typical applications include face milling, shoulder milling, and high-productivity roughing to semi-finishing passes on ferrous and difficult-to-cut materials in both job shop and production environments. The MM chip breaker geometry supports reliable chip control across this material range.

Key Features

• Octagonal insert shape provides 16 cutting edges per insert, maximizing cost-per-edge value
• IC928 grade with TiAlN PVD coating for high wear resistance on steel, stainless steel, superalloys, and titanium
• Negative rake with T-Land cutting edge style for edge strength on interrupted cuts and hard materials
• Double-sided design with neutral hand - fits both right- and left-hand cutter configurations
• MM chip breaker geometry engineered for controlled chip evacuation on P, M, and S workpiece materials
• Screw-held insert mounting for secure, repeatable seating in compatible cutter bodies

Compatibility

Designed for use in ISCAR 16MILL series cutter bodies, specifically confirmed compatible with the F45NM and F45WG cutter series. Conforms to ANSI and ISO 13399 standards under the designation ONMU 080608-TN-MM IC928.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC toolroom technician with the spindle fully de-energized and locked out per facility LOTO procedures. Use the appropriate torx or hex key to the cutter body manufacturer's specified seating procedure - do not overtighten the clamping screw, as this can fracture the carbide insert. Inspect the insert pocket and screw threads for debris or damage before seating a new edge. Handle carbide inserts with care to avoid chipping cutting edges prior to use.
