Iscar 5508107 DNMG431TF IC8250 Turning Insert Carbide

Product Description

The ISCAR 5508107 is a DNMG431TF IC8250 grade indexable turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured from solid carbide with a CVD-applied TiCN, Al2O3, and TiN multilayer coating, this insert delivers wear resistance and thermal stability during continuous and interrupted cuts. The diamond-shaped insert (55-degree included angle) provides a 0.016-inch corner radius and a 0.5-inch inscribed circle diameter. It belongs to ISCAR's Isoturn series and is suited for machinists and tooling specialists working in high-production or precision turning environments.

The 5508107 is engineered for turning and boring operations on stainless steel and steel workpieces, corresponding to ISO material groups M and P. The TF chip breaker geometry promotes positive rake cutting action, making it effective for medium to light finishing passes. With a maximum depth of cut of 0.118 inches (3.00 mm), it is well suited for finishing and semi-finishing turning passes in both residential shop environments and large-volume industrial machining cells. Boring is listed as a confirmed multi-use application.

Compatibility

Designed for use in DNMG-style toolholders that accept a 431 insert size code with clamp or pin clamping. Compatible with turning and boring applications on stainless steel and steel workpieces as identified by ISO material groups M and P. Verify toolholder pocket specifications and clamping style before installation.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Always power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert firmly against the pocket locating surfaces before engaging the clamp or pin to ensure accurate positioning and prevent insert movement under cutting loads. Follow the toolholder manufacturer's torque and clamping procedure for the specific holder in use.
