SNGG 120404 GT9530 indexable turning insert — ISO SNGG120404-01 by Tungaloy

A SNGG120404-01 GT9530 indexable turning insert engineered for external and internal turning, offering a coated cermet grade optimised for finishing and longer tool life in stable turning conditions

• Coated cermet GT9530 for long life
• ISO SNGG geometry for standard holders
• Fine surface finish on steel
• Cylindrical hole for secure clamping

Reliable finishing and longer tool life

The GT9530 coated cermet grade is designed as a wear-resistant finishing to light-universal grade for steel, delivering a balance between surface quality and tool life. The cermet coating reduces flank wear and maintains edge integrity under stable cutting conditions, which means more consistent part quality and fewer insert changes. For shops prioritising surface finish, this grade provides a measurable improvement in component appearance while maintaining predictable performance over a production run.

Consistent fit with ISO SNGG geometry

The insert follows ISO SNGG geometry, so compatibility with holders depends on form, relief, tolerance class, clamping method, size and thickness. The square 12 mm format and 4.76 mm plate thickness combine with a 0° relief angle and a 0.4 mm corner radius to give a reliable seating in standard external-holding tools. The cylindrical hole ensures secure clamping and repeatable positioning, reducing set-up variance and supporting reproducible results across batches.

Controlled chips and adaptable application range

Equipped with chipbreaker 01, the insert supports effective chip formation for external and internal turning tasks when the machining setup is stable. The chip control helps prevent entangling and supports continuous machining cycles, contributing to process reliability. For mixed production, selecting the correct chipbreaker and matching the GT9530 grade to the workpiece and cutting conditions will maximise productivity and minimise unplanned stoppages.

Simple integration into the tool system and predictable economy

The ISO plate integrates into a modular system comprising the insert, a compatible external holder or boring bar, a locating pad/clamp set and replacement fastening screws. Such a system approach streamlines inventory management and reduces downtime when inserts are changed. The cemented carbide substrate combined with the coated cermet top layer offers a compelling balance of precision, longevity and economical performance in series production environments.

FAQ

What materials is this insert suited for?
The SNGG120404-01 GT9530 insert is specified for machining steel with a focus on finishing operations where a good surface and extended life are required.

Which holders will accept the ISO SNGG120404-01 geometry?
Holders designed for ISO SNGG inserts that match form, relief angle, tolerance class, clamping method, size (12 mm) and thickness (4.76 mm) will accept the SNGG120404-01 GT9530 insert.

How does the GT9530 grade affect surface finish?
The GT9530 coated cermet reduces flank wear and maintains edge sharpness, producing a finer surface finish compared with conventional grades under stable turning conditions.

Is the insert suitable for both external and internal turning?
Yes, the insert is intended for external and internal turning; chipbreaker 01 and appropriate holder selection enable versatile application.

What are the key dimensions to check before fitting the insert?
Verify plate size (12 mm), thickness (4.76 mm), corner radius (0.4 mm), relief angle (0°) and the cylindrical hole compatibility to ensure correct fit and clamping.
