DCET 11T302 SH730 ISO turning insert, 55° rhombic – Tungaloy

The DCET11T302 SH730 is an ISO-standard rhombic indexable insert designed for external and internal turning, offering edge stability where engagement conditions vary.

• SH730 coated carbide grade
• 55° rhombic geometry for versatility
• 0.2 mm nose radius for fine turning
• One-sided chipbreaker for controlled chips
• Cylindrical hole with 40°–60° countersink

Productivity gains through a resilient cutting grade

The coated SH730 grade is formulated for edge stability under fluctuating engagement, making the insert particularly suitable for machining small tools and components. With a coated carbide substrate, the insert reduces the frequency of edge changes and supports steady cycle times, so throughput improves without complex process adjustments. The 55° rhombic layout provides a favourable cutting direction for a range of operations, and the modest 0.2 mm nose radius helps achieve precise contours while maintaining acceptable tool life. These properties together enable a reliable balance between surface quality and economical cutting performance.

Clear compatibility with ISO toolholder systems

This indexable insert conforms to ISO dimensions and is intended for use with matching external or boring toolholders; compatibility depends on form, relief angle, tolerance class, attachment and thickness. The insert’s 7° relief angle and 3.97 mm plate thickness must be checked against the holder specification to guarantee correct seating and clamp pressure. Where stability is critical, pairing the insert with an appropriately rigid holder and verified clamping kit prevents chatter and extends usable edge life. For verification of holder match and recommended clamping sets, Metav Werkzeuge provides technical advice and specification checks.

Controlled chip formation and predictable edge behaviour

The one-sided chipbreaker design is optimised for consistent chip control in turning tasks, reducing the risk of entanglement and improving machine uptime. Combined with the SH730 coating technology, the cutting edge resists abrasive wear and maintains geometry under interrupted cuts or variable feed conditions. This results in reproducible part quality and less rework, which is particularly advantageous where batch consistency matters. The cylindrical locating hole with a 40°–60° countersink supports secure fastening and repeatable indexability during insert changes.

Practical selection and workshop handling tips

When selecting this insert for daily workshop use, consider the workpiece material and stability of the setup: the grade is optimised for versatile applications in turning, but choosing the correct chipbreaker and cutting data is essential for best results. Use conservative feeds for fine finishing with the 0.2 mm radius and increase feed gradually when roughing to preserve edge condition. Keep a set of spare clamps and screws in the tool crib to avoid downtime during index changes. If additional data or tailored cutting parameters are required, Metav Werkzeuge can supply cutting charts and compatibility guidance by email or phone.

FAQ

What materials is this insert suitable for?
The DCET11T302 SH730 insert is a coated carbide grade optimised for a broad range of turning tasks; the SH730 formulation targets stability under variable engagement, so it performs well on typical steel and mixed-material turning applications.

Which holders fit this ISO insert?
Compatibility requires a holder that matches the ISO form DCET, the 7° relief angle, plate thickness 3.97 mm, and the 55° rhombic seating; verify the holder’s clamping system against these dimensions before assembly.

How does the 0.2 mm nose radius affect finish and feeds?
A 0.2 mm nose radius favours finer surface finishes and reduced cutting forces in finishing passes; for roughing, increasing feed while monitoring tool life is recommended to avoid premature edge chipping.

Can this insert be used for internal turning (boring)?
Yes, the ISO rhombic form and secure locating hole allow use in compatible boring bars for internal turning, provided the bar supports the 11 size and the 3.97 mm thickness.

What does the chipbreaker type mean for machining?
The one-sided chipbreaker gives consistent chip control in turning and helps prevent long, tangled chips; it is especially useful in automated or multi-part production where reliable chip evacuation matters.
