DCET 11T301 SH730 – DCET turning indexable insert, 55° rhombic, Tungaloy

DCET 11T301 SH730 is an ISO-standard indexable turning insert intended for external and internal turning applications with a focus on edge stability for small tools and variable cutting conditions

• Coated carbide grade SH730 for edge stability
• ISO 55° rhombic geometry for wide holder fit
• Single-sided chipbreaker for varied cutting conditions

Reliable edge performance for varied turning tasks

The DCET11T301 insert combines a coated carbide substrate with the SH730 grade to deliver consistent edge stability even when engagement conditions change. The applied coating and substrate chemistry are selected to resist cratering and wear, which translates into longer effective tool life and fewer unscheduled indexings. For operations where small-tool rigidity and repeatable chip formation matter, this insert reduces the frequency of tool changes and helps maintain cycle-time consistency, supporting improved production efficiency and predictable part quality.

Interchangeability that speeds up tooling setups

Designed to ISO dimensions, the insert’s 55° geometry and standardised form ensure compatibility across a broad range of holders when matched by form, clearance, tolerance class, fixing method, size and thickness. The 3.97 mm thickness and 11 mm nominal size make the insert straightforward to fit into common external holders and boring bars, while the 7° clearance angle supports secure seating and reduced rubbing. This interchangeability reduces setup complexity and shortens downtime during tool replacement, enabling more reliable machine utilisation and faster changeovers.

Predictable chip control and stable cutting behaviour

The single-sided chipbreaker is optimised for stable chip formation under a variety of feeds and depths of cut. Combined with the insert’s rhombic form and the central cylindrical hole with a single-sided countersink (40°–60°), clamping is positive and repeatable, which contributes to consistent cutting forces and improved surface quality. Better chip control lowers the risk of entanglement or irregular evacuation, supporting safer operation and easier downstream handling. These technical choices aid both finishing passes and medium-accuracy production where repeatability matters.

Practical selection and mounting advice for consistent results

When specifying this insert, match the plate to a holder that accepts the rhombic 55° form and accounts for the corner radius 0.1 mm for the desired edge engagement — small radii favour finishing and tight-tolerance profiling. Ensure the insert seat is clean and that clamping hardware (including any underlay or clamp set) meets the tolerance class required for secure fastening. The SH730 grade is intended for robust edge life with changing conditions, so selecting an appropriate feed and cutting speed will preserve the cutting edge and reduce vibration. If required, Metav Werkzeuge’s technical team can provide application guidance to integrate the insert into a specific machining process and recommend clamping hardware and torque settings.

FAQ

What corner radius does this insert have and what is it best used for?
The DCET11T301 insert features a corner radius of 0.1 mm, which is suited to finishing operations and fine profile work where small radii and a sharp cutting edge support tighter tolerances and improved surface finish.

How does the insert fit into common toolholders?
Compatibility depends on form, clearance, tolerance class, fixing method, size and thickness; the ISO 55° rhombic form and 3.97 mm thickness of the DCET 11T301 make it suitable for many ISO-compatible turning holders when the holder accepts the DCET geometry (SKU: TUN6856623) and the correct clamping arrangement is used.

Which cutting conditions are ideal for the SH730 grade?
The SH730 grade is a tough, edge-stable coated carbide designed for turning where variable engagement or smaller toolholders are present; it offers a balance of wear resistance and toughness for repeatable machining under fluctuating loads.

What clamping arrangement is required for secure seating?
The insert uses a central cylindrical hole with a single-sided countersink (40°–60°); this arrangement provides a positive location for the clamping screw and helps ensure repeatable seating and stable cutting when matched with the correct clamp set and replacement screws.

Is this an indexable insert and can it be rotated to a fresh edge?
The DCET 11T301 is an indexable turning insert designed for rotation or replacement according to its rhombic geometry and single-sided chipbreaker; consult the insert orientation and holder compatibility to determine the number of usable cutting positions for a given setup.
