Iscar 5509501 Turning Insert WBMT520L IC830 Carbide

Product Description

The ISCAR 5509501 is a solid carbide turning insert in the WBMT520L geometry, designed for left-hand turning operations on CNC lathes and turning centers. It carries the IC830 manufacturer grade and features a dual-layer PVD coating of AlTiN and Titanium Nitride, which provides heat resistance and extended tool life across demanding cut cycles. The trigon insert shape delivers an 80-degree included angle, and the 0.20 mm corner radius (0.0079 inches) suits finishing and semi-finishing passes. Maximum depth of cut is 2.00 mm (0.0787 inches). This insert is part of the Isoturn series and is sold individually with a minimum order quantity of 10 pieces.

This insert is rated for primary workpiece material codes M, P, and S, covering stainless steel, carbon and alloy steels, and superalloys. It is suited for external and internal profiling applications where left-hand tool orientation is required. The T-style chipbreaker controls chip flow during continuous and interrupted cuts at moderate to high cutting speeds. Machinists and tooling specialists in production shops, job shops, and aerospace or energy component machining environments will find this insert a direct fit for precision turning programs.

Compatibility

Designed for use in WBMT-style left-hand turning toolholders within the ISCAR Isoturn series. Verify toolholder pocket geometry and insert seating before use. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician with the machine in a powered-down, locked-out state per applicable lockout/tagout procedures. Use the appropriate torque driver or clamping screw tool specified for the toolholder to seat the insert securely without over-torquing the clamping mechanism. Inspect the insert pocket for wear or debris before seating a new insert. Always confirm insert orientation matches the toolholder hand designation before resuming operations.
