Iscar 5400943 Pcd Turning Insert Ccmt 3-1 Isoturn

Product Description

The ISCAR 5400943 is a single-tipped Polycrystalline Diamond (PCD) turning insert in the CCMT 3-1 style, designed for high-precision machining of non-ferrous metals. It carries an 80-degree diamond shape with a 3/8 inch inscribed circle, a 1/64 inch corner radius, and a 7-degree relief angle. The insert measures 9.70 mm (0.3819 inch) in length and 5/32 inch in thickness. It is uncoated and classified under ISCAR grade ID5. This insert is intended for use in CNC turning applications by machinists and tooling technicians working with aluminum, copper, brass, and similar non-ferrous workpiece materials.

The ISCAR 5400943 belongs to the Isoturn series and is suited for turning operations on non-ferrous metals where surface finish and tool life are critical. With a positive rake angle of 4 degrees and a T-style chip breaker, it handles light to moderate depths of cut up to 3.00 mm (0.1181 inch). The screw-holding method provides secure clamping in compatible CCMT-style toolholders. This insert is appropriate for production turning environments and precision shop applications where consistency across passes is required.

Key Features

Compatibility

Designed as a CCMT 3-1 style replacement insert for use in compatible screw-clamp CCMT turning toolholders within the ISCAR Isoturn series. Verify toolholder pocket dimensions and insert seat geometry before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before handling any cutting inserts or adjusting the toolholder. Use the appropriate torx or hex key to torque the clamping screw to the toolholder specification — do not overtighten, as this can fracture PCD tips. Inspect the insert pocket and clamping screw for wear or debris before seating the insert.
