DCMT 11T312 T5115 Wendeplatten - Tungaloy

Take advantage of the combination of a CVD‑coated carbide grade formulated for cast iron, a stabilising rhombic geometry and a 1.2 mm corner radius to secure consistent component finish and extended cutting performance; order or request application guidance through Metav Werkzeuge if needed.

DCMT11T312 11T312 T5115 — ISO turning indexable insert for turning, Tungaloy

The DCMT11T312 T5115 is an ISO‑standard rhombic indexable insert intended for external and internal turning; it combines a CVD‑coated carbide grade with a controlled geometry to balance wear resistance and edge stability in cast‑iron operations.

• ISO rhombic insert, 11 mm size
• CVD‑coated cemented carbide T5115
• 7° clearance angle for stable cutting
• Cylindrical hole with 40°–60° countersink

Reliable performance for cast‑iron turning

The CVD‑coated T5115 cemented carbide offers a balanced mix of wear resistance and edge stability specifically tuned for cast‑iron machining, which reduces unexpected tool changeovers and supports steady production flow. By selecting a universal grade aimed at grey and ductile cast irons, the tool life becomes more predictable and surface finish more consistent; this translates into lower rework rates and improved throughput on batch runs and single‑piece production alike.

Geometry and seating for steady results

The rhombic shape with an effective 1.2 mm corner radius and a 7° clearance angle gives the insert a secure seat and resilient cutting edge in standard ISO toolholders. The insert’s 11 mm size and 3.97 mm thickness are matched to common holder families; compatibility is governed by form, clearance angle, tolerance class, fastening and plate thickness. The insert features a cylindrical hole with a single‑sided countersink (40°–60°) to ensure repeatable clamping and reduced vibration, which benefits surface quality and extends insert life.

System‑level approach and practical selection advice

An efficient turning setup pairs the indexable plate with a suitable external holder or boring bar, plus the correct shim, clamping kit and replacement screws. Choose the one‑sided chipbreaker and grade according to workpiece material, depth of cut and machine/tooling rigidity to optimise chip control and cutting forces. For less experienced planners: a smaller corner radius improves finish on light cuts, while the 1.2 mm radius here improves edge strength for interrupted cuts or heavier stock removal.

FAQ

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the DCMT11T312 insert fits standard ISO holders designed for 11 mm rhombic plates and secures via a cylindrical hole with a single‑side countersink.

Is this insert suitable for interrupted cuts in cast iron?
Yes; the DCMT11T312 with the T5115 CVD‑coated carbide grade provides a compromise between wear resistance and edge strength, making it appropriate for interrupted conditions in many cast‑iron applications.

What chipbreaker should be selected for finishing cuts?
For finishing cuts choose the finer chipbreaker variant compatible with this plate; the DCMT11T312 is supplied with a one‑sided chipbreaker, and pairing a smaller depth of cut with the same chip control geometry improves surface finish.

Where can cutting data for the T5115 grade be obtained?
Recommended cutting speeds and feeds for the T5115 grade are available from Tungaloy’s technical documentation and can be discussed with Metav Werkzeuge’s consultants to match machine rigidity and workpiece specifics.
