TCMT 16T312 T5115 indexable turning insert by Tungaloy — CVD-coated carbide, 1.2 mm radius

TCMT16T312 T5115 is an ISO-compliant triangular indexable insert designed for external and internal turning applications, optimised for cast iron machining.

• CVD-coated carbide T5115 for cast iron
• 1.2 mm corner radius for robust edge
• ISO TCMT16T312 triangular insert form
• Compatible with holders using 40°–60° countersink

Predictable tool life through a balanced grade

The CVD-coated cemented carbide grade T5115 is formulated to give an even balance between wear resistance and edge stability when machining cast iron. That balance reduces unexpected flank wear and supports consistent cycle times on production runs. The universal character of the grade simplifies grade selection across a range of cast-iron alloys, enabling planners to standardise tooling while maintaining surface quality and tool life.

Geometry that increases cutting stability and clamping reliability

The triangular form with a 60° insert angle, a 1.2 mm corner radius and a 7° clearance angle delivers a robust cutting edge and predictable load distribution. The plate’s thickness of 3.97 mm and the design with hole and single-sided countersink (40°–60°) ensure secure seating and repeatable clamping torque, reducing vibration and edge chipping. These geometric choices translate into improved part finish and fewer indexing events during high-production sequences.

ISO compatibility reduces stocking complexity

Compliance with ISO dimensions and the standard designation ensures interchangeability with many established holders. Compatibility depends on form, clearance angle, tolerance class, clamping method, size and thickness; the system build typically comprises the holder, a shim/clamp, and replacement screws. Using ISO‑conform inserts simplifies procurement and allows existing toolholders to be reused, lowering inventory costs while keeping process reliability high.

Application advantages and handling recommendations

The insert performs in both external and internal turning and features a one-sided chipbreaker suited to cast iron chip formation. Select a chipbreaker and cutting parameters that match workpiece material, machining method and machine rigidity to exploit the grade’s strengths. With correct feeds and speeds, the combination supports stable metal removal and good surface quality, increasing overall productivity and reducing rework rates.

FAQ

What materials is this insert suitable for?
The TCMT16T312 T5115 indexable insert from Tungaloy is designed primarily for cast iron machining, offering a balanced combination of wear resistance and edge stability for a range of grey and nodular cast irons.

How is the insert secured in the holder?
The insert uses a central hole with a cylindrical bore and a single-sided countersink (40°–60°), enabling secure seating in compatible holders when combined with the appropriate shim/clamp and screws.

Can this insert be used for internal turning as well as external turning?
Yes, the TCMT16T312 T5115 insert is suitable for both external and internal turning; select an appropriately sized holder and consider machine rigidity to maintain stability.

What effect does the 1.2 mm corner radius have on machining?
A 1.2 mm corner radius improves edge strength and distributes cutting forces, helping to prevent edge chipping and giving more consistent surface finish under interrupted cuts typical in cast iron turning.

Is the grade easy to integrate into an existing ISO tooling system?
Designed to ISO dimensions, this insert fits many standard holders; compatibility should be checked by matching form, clearance angle, tolerance class, clamping method, size and thickness — the system typically includes a holder, shim/clamp and replacement screws.
