CPMT 120412 T5115 ISO indexable insert for Turning — Tungaloy

The CPMT120412-CM T5115 is an ISO rhombic indexable insert designed for external and internal turning applications, optimised for cast-iron machining with reliable chip control.

• CVD-coated carbide universal grade T5115
• 11° clearance for stable cutting
• 1.2 mm corner radius for robustness
• Rhombic ISO shape, 12 mm size

Increased productivity through balanced grade and geometry

The combination of a CVD-coated carbide substrate and the T5115 grade provides a dependable compromise between wear resistance and edge toughness, especially in cast-iron applications. The rhombic plate form and the CM chipbreaker geometry support consistent chip formation, which reduces interruptions and allows longer uninterrupted cutting times. This results in fewer insert changes and improved cycle times on batch runs, making the component suitable for production environments where both process reliability and predictable tool life are priorities.

Stable cutting behaviour and reliable seating in holders

Built to ISO plate dimensions and tolerances, the insert features a 1.2 mm corner radius and an 11° clearance angle, which together offer mechanical strength at the cutting edge and reduced rubbing on the flank face. The 80° included angle supports robust contact with matched external or boring holders, while the cylindrical hole with single-sided countersink (40°–60°) ensures secure clamping and repeatable positioning. These design elements minimise vibration and edge chipping, translating into a consistently high surface finish and reduced rework.

Practical selection and material guidance forTurning

When machining cast iron, selecting an insert with balanced toughness and abrasion resistance is essential; the T5115 grade is formulated for exactly this role. Use the rhombic ISO geometry for general-purpose external turning and light to medium internal operations where chip control and stable cutting forces are required. Match the insert with a compatible external holder or boring bar that corresponds to the ISO size, thickness (4.76 mm) and fixation style to ensure correct seating. For higher-speed operations, verify machine stiffness and coolant strategy to obtain the full benefit of the CVD coating.

FAQ

What materials is this insert designed for?
The insert is specified for turning, with the T5115 grade optimised as a universal solution for cast-iron machining and balanced wear resistance.

How does the chipbreaker affect performance?
The CM chipbreaker promotes predictable chip formation and evacuation, improving process stability and reducing the risk of built-up edge during cast-iron turning.

Which holder types are compatible with this ISO plate?
Compatibility is determined by plate form, thickness (4.76 mm), hole style and tolerance class; use holders and boring bars complying with ISO dimensions for 12 mm rhombic inserts.
