DCMT 11T308 11T308 GT9530 — Turning insert by Tungaloy for finishing with coated cermet

A DCMT11T308 GT9530 ISO turning insert designed for finishing and light universal turning in steel, offering a wear-resistant GT9530 grade and ISO rhombic form for consistent surface quality.

• ISO rhombic DCMT shape 55° for versatile turning
• Coated cermet GT9530 for extended tool life
• Designed for finishing and light general turning
• Cylindrical hole with one-sided countersink

Improved surface finish with extended service life

The coated cermet composition of the GT9530 grade combines hard ceramic particles with a metal binder to deliver a balance between wear resistance and edge toughness. This makes the insert particularly suited to finishing passes and light general turning where a consistent surface finish and longer intervals between indexings are required. The GT9530 finish-oriented grade reduces built-up edge formation on steel, helping to maintain dimensional stability and reduce rework. In practice, this means fewer interruptions and steadier process outcomes when machining stable components.

Simple compatibility and secure clamping for quick tool changes

The insert follows ISO geometry, so compatibility with external holders and boring bars depends on the insert form, relief angle, tolerance class, mounting style, size and thickness. The 55° rhombic shape and 7° relief angle support versatile mounting options, while the cylindrical hole with a single-sided countersink (40°–60°) ensures repeatable seating in most ISO clamping systems. The plate thickness of 3.97 mm and the 0.8 mm corner radius contribute to stable clamping and predictable cutting forces, enabling fast changeovers with the appropriate shim or clamping set and replacement screws.

Practical application guidance for reliable machining

Suitable for both external and internal turning, the insert performs best under stable cutting conditions where finishing and light turning are required. Select a matching chipbreaker and grade according to workpiece material and machine rigidity; the single-sided chipbreaker on this insert supports controlled chip formation in continuous cuts. The 0.8 mm corner radius offers a compromise between edge strength and fine surface quality—larger radii increase robustness, smaller radii improve finish—so choose the radius in line with part tolerance and feed rate. For repeatable outcomes, pair the insert with a correctly sized external holder and maintain consistent machining parameters.

FAQ

What materials is this insert intended for? The GT9530-coated cermet grade is intended primarily for machining steel; the DCMT11T308 insert from Tungaloy is optimised for finishing and light general turning in stable conditions.

How does the 0.8 mm corner radius affect performance? A 0.8 mm corner radius increases edge strength compared with smaller radii while still supporting a good surface finish; the DCMT11T308 balances robustness and finishing ability.

Which holders are compatible with this ISO insert? Compatibility depends on holder form, relief angle, tolerance class, mounting style, size and thickness; the ISO rhombic geometry and cylindrical hole with countersink allow use with standard external holders and boring bars designed for DCMT inserts.

Is the GT9530 suitable for interrupted cuts? GT9530 is a finish-to-light universal grade designed for stable conditions; for heavy interrupted cuts, a tougher grade is recommended instead of GT9530.

What system components are recommended when fitting the insert? Use a matching external holder or boring bar, appropriate underlay/shim and the specified replacement screws to ensure repeatable clamping and correct seat geometry for the insert.
