Iscar 5540033 VCGT330AS IC20 Turning Insert 3/8 Inch Ic

Product Description

The ISCAR 5540033 is a solid carbide turning insert in the VCGT330AS style, manufactured under the Isoturn series. It carries the IC20 uncoated carbide grade and is designed for positive-rake external turning operations on CNC lathes and turning centers. The insert features a 35-degree diamond shape (V-code) with a clearance code of C and tolerance code of G, making it suitable for precision finishing and semi-finishing passes. It measures 0.6535 inches in length with a 3/8 inch inscribed circle, a corner radius of 0.0079 inches, and an insert thickness of 0.1874 inches. Screw-held mounting keeps the insert secure under cutting loads. Material grades C2 and C3 apply.

This insert is used in general turning applications targeting non-ferrous metals, stainless steels, and heat-resistant alloys, corresponding to ISO workpiece material groups K, M, and N. The AS chip breaker geometry promotes controlled chip formation during light to medium finishing cuts. It is commonly installed in standard VCGT-style toolholders on production turning centers and manual lathes in manufacturing and machining environments. Maximum depth of cut is 0.0980 inches (2.50 mm). The insert meets ISO 13399 standards for cutting tool data representation.

Installation Notes

Turning inserts of this type are installed and indexed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key to secure the clamping screw to the toolholder manufacturer specifications - do not overtighten. Inspect the toolholder pocket seat for debris or wear before seating the insert to ensure proper contact and dimensional accuracy.
