TPMT110202 GH730 Tungaloy insert — ISO triangular indexable turning insert, 60°, 0.2 mm nose radius

The TPMT110202 GH730 is an ISO-format indexable turning insert intended for external and internal turning, combining a cemented carbide substrate with a chipbreaker and a cylindrical clamping hole for secure fixation in compatible toolholders

• GH730 grade for wear resistance
• ISO triangular insert, 60°
• 0.2 mm nose radius for precision
• Cemented carbide, with clamping hole

Consistent cutting performance that reduces process variation

The combination of the GH730 cutting grade and a cemented carbide substrate delivers a measured compromise between abrasion resistance and fracture toughness. In production environments where repeatability matters, this balance extends usable edge life and reduces unscheduled insert changes. The 0.2 mm nose radius supports fine-detail turning and repeatable surface finish while the 60° triangular geometry ensures stable seating in ISO-compatible holders. These attributes translate into fewer interruptions and a more consistent cycle time across batches.

Secure clamping and straightforward system integration

Compatibility with a toolholder depends on form, relief angle, tolerance class, fixing method, size and thickness; this ISO-format insert facilitates straightforward integration into existing turning systems. The cylindrical hole with single-sided countersink (40°–60°) provides reliable clamping and repeatable positional accuracy, while the 2.38 mm plate thickness and standard 11 mm size match common holder designs. Assembling the system requires the insert, a matching outside holder or boring bar, an underlay/shim or clamp set and replacement screws — a practical setup for maintenance planning and spare‑parts provisioning.

Material behaviour and edge stability for mixed workloads

The Tungaloy grade is engineered to perform across a broad range of steels and alloys by offering stable chip formation and a resilient cutting edge. When machining varied components, selecting a single-sided chipbreaker and the GH730 grade helps maintain surface quality under changing cutting forces. The insert’s geometry and the grade’s properties minimise edge chipping and support predictable tool life, which is particularly valuable for medium-duty turning operations where both durability and finish count.

Practical guidance for application and insert selection

For best results in external and internal turning, match the chipbreaker and the GH730 sort to the workpiece material and the rigidity of the setup. A more rigid machine and workholding permit higher feed and depth of cut, leveraging the insert’s wear resistance; conversely, less stable arrangements benefit from conservative feeds to protect the cutting edge. The ISO designation and standard dimensions simplify inventory management and reorders, while the TPMT110202 geometry supports a range of turning tasks without the need for frequent retooling

FAQ

What toolholders are compatible with this insert?
Compatibility is determined by the insert’s form, relief angle, tolerance class, fixing method, size and thickness; the TPMT110202 fits holders designed for ISO-format triangular inserts and secures via the cylindrical hole and countersink.

Which materials can be machined with this grade?
The GH730 grade on the TPMT110202 insert is intended for turning a broad range of steels and similar alloys, offering a balance of wear resistance and toughness for mixed applications.

How does the 0.2 mm nose radius affect surface finish?
A 0.2 mm nose radius on this indexable insert supports a fine surface finish while retaining edge strength; it is suited to finishing and light-medium turning passes where dimensional accuracy is required.

Is the insert suitable for internal turning?
Yes — the TPMT110202 insert’s ISO geometry and chipbreaker selection permit use in both external and internal turning operations, provided the holder and setup offer adequate rigidity.

What is the exact article number and manufacturer code?
The article number is 6821010 and the manufacturer SKU is TUN6821010 for the TPMT110202 GH730 Tungaloy insert.
