SCMT 09T304 T5115 turning insert by Tungaloy – ISO square turning insert, CVD-coated carbide, 0.4 mm radius

The SCMT09T304 T5115 is an ISO-standard square insert designed for external and internal turning, optimised for cast iron with a balanced combination of wear resistance and edge stability.

• CVD-coated carbide grade T5115
• Universal grade for cast iron machining
• 0.4 mm corner radius for fine finishing
• Square 09 insert with 90° cutting angle
• Central hole with cylindrical plus 40°–60° countersink

Reliable performance for cast iron turning

The CVD-coated carbide grade T5115 provides a reliable compromise between wear resistance and edge stability, making the insert well suited to the typical demands of cast iron turning. The chemical vapour deposition (CVD) layer increases surface hardness and thermal resistance, which helps to maintain a consistent cutting edge under interrupted cuts and medium cutting speeds. As a result, machining times remain predictable and tool changes are less frequent, supporting continuous production workflows and lower overall tooling costs.

ISO compatibility and secure clamping

Designed to the ISO plate family, the insert’s compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness. The square 09 geometry and a 90° cutting angle deliver straightforward set-up for standard external and internal operations. The plate is supplied with a central hole and a cylindrical bore plus a one-sided countersink (40°–60°) for positive screw clamping; this arrangement ensures secure seating in a matching holder and consistent rigid support during heavy or interrupted cuts. Clear specification of these parameters reduces setup time and prevents incorrect mating with the toolholder.

Stable cutting edge and consistent productivity

With a single-sided chipbreaker and a modest 0.4 mm corner radius, the insert supports fine finishing while preserving edge strength. The engineered chip control of the breaker promotes predictable chip formation and evacuation when paired with a suitable holder and cutting parameters, which contributes to safer machining and less downtime. The balanced properties of the grade reduce the need for excessive feeds or speeds to protect the edge, allowing processes to be optimised for both surface finish and throughput without sacrificing tool life.

Assembly guidance, chip control and application notes

The insert forms part of a system: an ISO insert, a compatible external holder or boring bar, a backing shim/clamp set and the correct replacement screws. Select the chipbreaker and the grade to match the workpiece material, machining operation and machine/tool stability; the T5115 grade is intended as a universal solution for cast iron. For mixed or less stable setups, choose a chipbreaker or holder that prioritises firm clamping and improved chip evacuation. Technical datasheets and component drawings should be consulted to confirm tolerance classes and seating geometry before final assembly.

FAQ

What materials is this insert intended for?
The SCMT09T304 T5115 turning insert is formulated as a universal grade for machining cast iron and offers a balanced mix of wear resistance and edge stability for such applications.

Which geometric specifications define the insert?
The insert is a square 09 plate with a 90° cutting angle, a 0.4 mm corner radius and a thickness of 3.97 mm; it has a 7° clearance angle and a central hole with cylindrical bore plus a one-sided countersink (40°–60°).

How is the insert fixed to the holder?
Fixing relies on the central hole and the countersink style; the combination of form, clearance angle, tolerance class, fastening method, size and thickness defines compatibility with a chosen holder or boring bar.

What advantages does the CVD coating provide?
The CVD coating on the T5115 grade increases surface hardness and thermal resistance, improving wear behaviour and maintaining edge integrity under normal turning conditions, which supports more consistent process results.

Is the insert suitable for fine finishing operations?
Yes; the 0.4 mm corner radius and the balanced grade characteristics make the insert appropriate for finishing and semi-finishing passes when paired with correct feeds and stable setups.
