Iscar 5550450 Turning Insert Tcmt Triangle IC807 Isoturn

Product Description

The ISCAR 5550450 is a TCMT-style triangular turning insert designed for general-purpose and universal material turning applications. It features a solid carbide substrate with a TiAlN coating applied via PVD process, carrying ISCAR grade IC807. The insert has a 3/8 inch inscribed circle, a 60-degree included angle, a 1/64 inch corner radius, and a positive rake geometry. The SM chip breaker designation makes it suitable for a wide range of cutting conditions. Licensed HVAC and machining professionals working with CNC lathes or manual turning centers will recognize this as a screw-held insert with a center mounting hole.

This insert is rated for universal primary workpiece material, covering material codes H, K, M, P, and S under ISO 13399 classification. That range spans steels, stainless steels, cast irons, non-ferrous materials, and heat-resistant superalloys. It is commonly used in finish to medium turning passes. The insert sits in the Isoturn series and is supplied individually per package, with a minimum order quantity of 10 units per order.

Key Features

• Solid carbide substrate with TiAlN PVD coating for wear resistance across multiple material groups
• IC807 grade with SM chip breaker for controlled chip formation in universal turning applications
• TCMT insert style with positive rake and 7-degree relief angle for reduced cutting forces
• 3/8 inch inscribed circle with 60-degree triangle shape for three usable cutting edges
• Screw-held mounting with 0.1732 inch hole diameter for secure insert seating in compatible toolholders
• Compliant with ISO 13399 tooling data standards for digital tool management integration

Compatibility

Designed for use in TCMT-style screw-clamp turning toolholders within the ISCAR Isoturn series. Compatible with workpiece material codes H, K, M, P, and S as defined by ISO 13399.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or tooling technician with the machine fully stopped and the spindle locked out. Use the appropriate torx or hex key as specified by the toolholder manufacturer to seat the clamp screw to the correct engagement without over-torquing. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert. Handle carbide inserts with care, as the cutting edges are brittle and susceptible to chipping from impact.
