TBTR 040900 SH725 — Tungaloy triangular ISO turning insert, coated carbide, single‑sided chipbreaker

The TBTR040900 SH725 is an ISO‑standard triangular turning insert designed for external and internal turning, offering a tough, edge‑stable coated carbide grade for variable engagement conditions.

• ISO‑standard triangular insert 04
• Coated carbide SH725 for edge stability
• Single‑sided chipbreaker for chip control
• 5° relief angle for secure clearance

Boosted productivity through a tougher cutting grade

The coated SH725 grade offers a tough, edge‑stable performance that is particularly effective in turning applications where engagement conditions change or where smaller tool holders are used. By selecting a coated carbide grade designed for resilience rather than pure wear resistance, the result is fewer unexpected edge failures and reduced machine downtime. This translates into a more predictable process and improved component throughput, especially valuable in production runs where repeatability and consistent surface quality matter.

Geometry that ensures secure clamping and reliable chip control

The triangular 04 format with a single‑sided chipbreaker combines a robust geometry with simplified chip management. The insert’s 5° relief angle and 60° included angle provide predictable cutting forces and secure clearance, while the absence of a hole means the insert is used with a compatible clamping system. Compatibility is governed by form, relief angle, tolerance class, fastening method, size and thickness, so selecting the appropriate holder and clamp ensures correct seating, repeatable indexing and safe cutting performance.

Practical advantages and application guidance

For both external and internal turning, the combination of ISO classification, a clearly defined insert size and the SH725 grade helps reduce set‑up time and simplifies inventory. The coated carbide substrate supports long edge life under moderate feeds and interrupted cuts. When choosing an insert for a specific workpiece material, pair the chipbreaker style and the SH725 grade to the material and stability of the set‑up to achieve the best surface finish and tool life. For machinists transitioning from general‑purpose grades, this insert offers a balance between toughness and wear resistance that reduces the need for frequent index changes.

Installation, indexing and maintenance considerations

Because the insert is supplied without a hole, secure mounting relies on the correct matching of the insert form and the clamping system on the toolholder; ensure the holder accepts triangular ISO‑type inserts of size 04 and thickness 9.52 mm. When indexing, confirm seating and clamp torque to avoid micro‑movement that could shorten edge life. The coated surface assists in reducing built‑up edge and facilitates easier chip evacuation with the single‑sided breaker, which can help maintain consistent cutting conditions and reduce post‑process inspection.

FAQ

What determines holder compatibility for this insert?
Compatibility is determined by insert form, 5° relief angle, tolerance class, fastening method, size and thickness; using a holder that matches the ISO triangular 04 geometry ensures correct seating for the TBTR040900 SH725 insert.

Which materials is the SH725 grade suited to?
The SH725 coated carbide grade is formulated for tough, edge‑stable performance in turning; selection of the chipbreaker and grade should be matched to the workpiece material and machining stability for optimal results.

How does the single‑sided chipbreaker affect chip behaviour?
A single‑sided chipbreaker guides chip formation on one face to promote controlled evacuation and consistent cutting forces, which can improve surface finish and reduce the risk of chip entanglement in many turning operations.

What does 'without hole' mean for mounting?
'Without hole' indicates the insert is clamped by a top clamp or screw in a compatible toolholder rather than located by a centre hole; proper clamp design and torque are important for repeatable performance.

Are these inserts ISO‑standardised for easy replacement?
Yes, the insert follows ISO turning insert conventions, which simplifies replacement and inventory management when paired with ISO‑compatible holders designed for triangular size 04 inserts.
