Combining the balanced wear resistance of the CVD-coated T5115 grade with the proven stability of an ISO triangular geometry yields consistent cutting performance in cast-iron turning; order the insert directly via Metav Werkzeuge or consult our technical team if required.

TPMR 110304 T5115 – Turning insert, ISO triangular, CVD-coated carbide (Tungaloy)

TPMR 110304 T5115 is an ISO triangular turning insert designed for external and internal turning of cast iron, offering a universal CVD-coated carbide grade for stable cutting and reliable edge life.

• CVD-coated carbide grade T5115
• Universal grade optimised for cast iron
• Triangular ISO insert, 11 mm size
• 0.4 mm corner radius and 11° clearance

Consistent tool life through optimised coating and grade

The combination of a CVD-coated surface and the T5115 carbide formulation provides a well balanced mix of wear resistance and edge stability for cast-iron applications. This composition reduces flank wear and helps maintain cutting geometry over longer cycles, which in turn supports predictable tool change intervals and lower process costs. The single-sided chipbreaker is matched to common cast-iron chip forms, improving chip control and reducing the risk of built-up edge that can affect surface finish.

Geometry and dimensions that ensure secure clamping and surface quality

The triangular ISO shape with an 11 mm inscribed circle and a plate thickness of 3.18 mm gives a robust seating area for secure clamping in standard external holders and boring bars. A 0.4 mm corner radius and 11° clearance permit smooth transitions between finishing and light roughing passes while helping to damp vibration and protect the cutting edge. Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening and plate thickness, so matching the insert geometry to the chosen toolholder ensures repeatable accuracy and improved surface finish.

System approach and practical application guidance

As part of an ISO indexable insert system, the TPMR geometry works with a matching external holder or boring bar, a suitable backing plate/clamp set and replacement screws to form a complete cutting assembly. Typical uses include external and internal turning where a universal grade for cast iron is desired; select the one-sided chipbreaker and grade according to workpiece material, machining method and assembly rigidity. The predictable behaviour of the insert reduces setup iterations and supports efficient, productive machining sequences in both single- and multi-shift production.

FAQ

What materials is this insert best suited to machine?
The TPMR110304 T5115 insert is specified as a universal grade for cast iron; the T5115 CVD-coated carbide balances wear resistance and edge stability for standard cast-iron turning tasks.

Which holders are compatible with this ISO triangular insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening, size and thickness; the triangular ISO geometry with 11 mm inscribed circle fits standard holders designed for that format.

How does the 0.4 mm corner radius affect cutting performance?
A 0.4 mm corner radius provides a compromise between cutting edge strength and surface finish, enabling smoother transitions and improved edge life in finishing and light roughing operations.

Is this insert suitable for internal turning?
Yes, the insert is designed for both external and internal turning applications when used with the appropriate boring bar or holder and correct assembly components.
