TPMT16T312-CM T505 — triangular ISO turning insert, CVD-coated carbide, 60° included angle

The TPMT16T312-CM T505 is a triangular ISO turning insert for general turning, optimised for economical and productive machining of cast iron components.

• ISO triangular insert for turning
• CVD-coated carbide grade T505
• Optimised for cast iron machining
• Cylindrical hole with countersink 40°–60°

High productivity for cast iron with consistent edge life

The insert combines a CVD-coated surface with a carbide substrate in grade T505, delivering a balance of wear resistance and cost efficiency that suits long production runs on cast iron. The chipbreaker CM is designed to control swarf formation for stable chip flow during continuous cuts, which reduces downtime associated with clearing chips. With a 1.2 mm corner radius, the geometry provides increased edge strength and predictable tool life while maintaining a good surface finish on external and internal turning operations. These properties make the component a pragmatic choice where repeatable performance and lower tool costs are priorities.

Designed for secure clamping and straightforward integration into ISO systems

The insert is made to ISO standards, so compatibility with a matched external holder or boring bar depends on form, clearance angle (11°), tolerance class, clamping method and thickness. The triangular form and 60° included angle allow three usable edges per indexable insert, improving cost-effectiveness per cutting edge. The central feature — a cylindrical hole with a one-sided countersink (40°–60°) — provides reliable positioning and clamping force in the pocket, which helps reduce micro-movements at the cutting edge under load. The 3.97 mm thickness ensures sufficient support in robust holders while the component’s ISO designation allows straightforward matching to existing toolholders and clamping sets.

Practical selection tips for process stability and chip control

When choosing cutting data, the main factors are workpiece stability, fixture design and whether the cut is continuous or interrupted. The CM chipbreaker is intended for cast iron applications and will typically perform best where steady engagement and consistent swarf evacuation are possible. For interrupted cuts or reduced rigidity, select a more robust holder or a smaller radial depth of cut to protect the cutting edge. The CVD coating reduces flank and crater wear, which extends usable edge life and supports higher material removal rates in many cases. For specific process windows and toolholder pairing recommendations, consult Metav Werkzeuge’s technical advisors who can help match the insert geometry and grade to the machining centre and workholding conditions.

FAQ

What materials is this insert best suited for?
The TPMT16T312-CM T505 insert is optimised for cast iron machining; the CVD-coated T505 grade provides good wear behaviour and economical edge life for this material class.

How does the chipbreaker CM affect machining?
The CM chipbreaker on the TPMT16T312-CM T505 controls chip shape and evacuation for stable machining, reducing the risk of chip entanglement and improving process reliability on continuous turning operations.

Is the insert compatible with standard ISO holders?
Yes — the insert follows ISO geometry. Compatibility with a specific holder is determined by form, 11° clearance, tolerance, clamping method, size and thickness; ensure the holder pocket matches these parameters.

How many cutting edges are available per insert?
The triangular form and 60° included angle provide three indexable edges per insert, maximising economy per cutting edge when used correctly in a matching holder.

What role does the CVD coating play?
The CVD-coated surface on the carbide substrate reduces flank and crater wear, supporting longer tool life and better performance at elevated cutting parameters compared with uncoated grades.
