TBTR 040400 SH725 ISO triangular turning insert, 60° — Tungaloy

TBTR 040400 SH725 is an ISO‑standard triangular indexable insert designed for external and internal turning, offering a 5° relief and a single‑sided chipbreaker for reliable chip formation.

• SH725 coated carbide for stable edge life
• ISO 040400 triangular 60° geometry
• 5° clearance angle for reliable penetration
• Single-sided chipbreaker for consistent chips

Predictable performance and extended edge life for turning

The combination of the SH725 coated carbide grade and the triangular 60° geometry ensures a balance between toughness and wear resistance, which is particularly valuable where engagement conditions vary. The coated carbide substrate provides enhanced surface protection and heat resistance, while the 5° clearance angle minimises flank rubbing and reduces the risk of built-up edge on difficult passes. For manufacturers seeking steady cycle times and fewer insert changes, this configuration supports consistent process outputs and contributes to productive machining across a range of components.

ISO compatibility that simplifies tooling management

Designed to ISO specifications, the insert fits into a conventional indexable system consisting of a matching outer holder or boring bar, a shim or clamp set and replacement screws. The ISO standardisation of form, tolerance class, mounting and size reduces setup time and inventory complexity, allowing straightforward interchangeability between compatible toolholders. For workshops running mixed batches or rapid changeovers, the standardised geometry and thickness give a quick, verifiable basis for selecting a holder and setup, helping to streamline tool logistics and reduce downtime.

Reliable chip control and application versatility

The single-sided chipbreaker on this insert promotes predictable chip segmentation during both external and internal turning, improving surface finish and facilitating chip evacuation in automated or confined setups. The stable cutting edge characteristic of the SH725 grade is especially suited to smaller tooling or operations where cut conditions alter frequently; it maintains edge security under intermittent cuts and supports repeatable part quality. For turned components where dimensional consistency and surface integrity matter, the indexable insert’s chip control and edge robustness help deliver measurable productivity gains and lower rework rates.

FAQ

What materials is this insert suitable for?
The TBTR 040400 SH725 insert (Tungaloy, SKU 6842933-Tungaloy) is a coated carbide grade intended for a broad range of turning tasks; selection of the chipbreaker and grade should match the specific workpiece material and machining mode.

How does the SH725 grade affect performance?
SH725 provides a tough, edge‑stable coating designed to maintain cutting-edge integrity under varying engagement conditions, so the TBTR 040400 SH725 supports consistent part quality and longer tool life in interrupted or small-tool operations.

Is this insert compatible with standard ISO toolholders?
Yes — the insert is ISO‑specified (040400) and compatibility depends on holder form, clearance, tolerance class, mounting style, size and thickness; matching an ISO holder and clamp kit ensures secure seating and repeatable performance.

What advantage does the single-sided chipbreaker provide?
The single-sided chipbreaker promotes predictable chip formation and evacuation, improving surface finish and reducing the likelihood of chip entanglement in both external and internal turning applications with this insert.

Can the insert be used for internal turning?
The geometry and chip control features make the insert suitable for internal turning where space and chip evacuation are considerations; use a compatible boring bar and ensure correct clamping to maintain stability.
