KNMX160405 GH330 Tungaloy indexable turning insert — 55° parallelogram, 0.5 mm radius

The KNMX160405 GH330 is an ISO-standard indexable turning insert engineered for external and internal turning, offering a balanced combination of wear resistance and edge stability for general turning tasks.

• KNMX160405 ISO insert, parallelogram shape
• GH330 grade for wear resistance and toughness
• 55° cutting edge angle for versatile turning
• 0.5 mm corner radius for reliable edge strength

Engineered for reliable, continuous turning performance

The insert’s GH330 cutting grade, developed by Tungaloy, combines wear resistance with sufficient toughness to maintain a stable cutting edge under varied cutting conditions. The use of a carbide substrate ensures consistent hardness and thermal stability during sustained operations, which contributes to longer tool life and fewer indexings. For production-oriented turning, this results in improved process stability and reduced downtime due to insert changes. The GH330 grade suits a broad range of steels and offers a compromise between abrasive wear protection and resistance to edge chipping.

Geometry and compatibility that simplify setup

The parallelogram shape with a 55° cutting edge angle and a 0.5 mm corner radius delivers versatile engagement for both finishing and light roughing passes. The insert conforms to ISO dimensions, so compatibility with carriage-mounted holders and boring bars depends on the holder’s form, relief angle (the insert has a 0° relief), tolerance class, clamping method, size and thickness. The insert features a special hole and hole style for dedicated clamping systems, so checking holder and screw compatibility before mounting is recommended. This geometry supports predictable cutting behaviour and straightforward toolpath planning.

Chip control and grade selection explained

Chip evacuation and surface finish are influenced by the chipbreaker design and how the insert grade interacts with the workpiece material. The KNMX160405 is supplied with a special chipbreaker tailored to targeted chip shapes and controlled evacuation under typical turning conditions. For machinists less familiar with chipbreaker function: the chipbreaker locally alters shear conditions to break and curl chips, reducing entanglement and easing coolant access. Selecting GH330 together with the appropriate chipbreaker balances edge stability and wear performance, improving process reliability when machining a variety of steels.

Practical application notes and system components

This insert is intended for external and internal turning as part of a system that includes a matching outer holder or boring bar, a shim/clamping set and spare screws. The system approach ensures repeatable clamping and positional accuracy. For initial setup, verify the insert’s orientation and clamping torque specified by the holder manufacturer; incorrect seating can compromise tool life and surface quality. Where high material removal rates or interrupted cuts occur, opt for more robust geometries or adjust feeds and depths to preserve edge integrity.

FAQ

What materials can be machined with this insert?
The KNMX160405 GH330 insert is designed primarily for turning steels; the GH330 grade provides a balance of wear resistance and toughness suitable for a wide range of steel alloys.

How does the parallelogram shape affect cutting?
A parallelogram geometry with a 55° edge angle offers versatile engagement, enabling controlled chip flow and suitability for both finishing and light roughing operations on shafts and bores.

Is the insert compatible with standard ISO holders?
The insert follows ISO dimensions, but compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness; check the holder’s specifications and the insert’s special hole style before mounting.

What is the purpose of the special chipbreaker?
The special chipbreaker design promotes predictable chip formation and evacuation, improving surface finish and reducing the risk of chip entanglement in typical turning operations.

Which spare parts are recommended for a complete system?
A complete system normally includes a suitable external holder or boring bar, a shim/clamping set and spare screws to ensure repeatable and secure clamping of the insert.
