Iscar 5605883 Milling Insert T490 Lnmt 1306PNTR IC5100

Product Description

The ISCAR 5605883 is a solid carbide milling insert carrying the ANSI designation T490 LNMT 1306PNTR IC5100. It belongs to the HELITANG series and is designed for face and shoulder milling operations where consistent chip control and edge integrity are critical. The insert features a butterfly (LNMT) shape with a helical cutting edge style, a negative rake angle, and a 90-degree included angle. CVD-applied TiCN and Al2O3 coating layers provide wear resistance and thermal stability. With four usable cutting edges and a double-sided configuration, it delivers extended tool life per insert. Maximum depth of cut reaches 0.492 inches. Licensed machinists and CNC operators working in production environments are the primary installers of this insert.

This insert is suited for milling cast iron workpieces, corresponding to ISO material application code K. It is engineered for use in the T490 LNK13 cutter series. Typical applications include roughing and semi-finishing passes on cast iron components in metalworking, automotive, and general machining operations. The screw-holding method ensures secure seating in compatible toolholders. Right-hand cutting orientation must be confirmed against the toolholder specification before installation.

Compatibility

Designed for use with the ISCAR T490 LNK13 cutter series. Confirm toolholder pocket geometry and screw size match T490 LNMT 1306 insert specifications before installation.

Installation Notes

Insert replacement is performed by CNC machinists or toolroom technicians following standard indexable insert procedures. Ensure the machine spindle is fully stopped and locked out before accessing the cutter body. Use the correct torx or hex key to the toolholder manufacturer's specified seating procedure to avoid insert rocking or premature edge failure. Verify right-hand cutting direction and confirm insert pocket is free of chips and debris before seating the new insert.
