Consistent cutting performance from a tough, coated carbide grade

The SH725 coated carbide grade is formulated for edge stability and toughness, which reduces chipping and extends effective cutting life under fluctuating engagement conditions. A coating over a carbide substrate moderates heat transfer and wear, so the insert maintains a reliable cutting edge during short interrupted cuts and varying depths of cut. This results in fewer unplanned changeovers and more consistent part quality on production lines that require repeatable turning cycles.

Versatile geometry and compatibility for straightforward tool selection

The triangular 60° form with a 5° relief offers a balance between positive cutting action and robustness; the 04 size and a plate thickness of 9.52 mm make this insert suitable for compact toolholders and smaller‑diameter applications. Compatibility with a holder depends on the insert’s form, relief angle, tolerance class, fastening, size and thickness — factors that ensure correct seating and clamping. Choosing the matching holder and clamp fastener simplifies setup and reduces fixture adjustments, thereby saving machine time.

Economical uptime and improved surface results

Using a grade optimised for a wide range of turning tasks yields tangible operational benefits: fewer tool changes, stable dimensional accuracy across runs and predictable surface finishes. The single‑sided chipbreaker design supports controlled chip formation, lowering the risk of recutting and improving surface integrity on turned parts. For production environments aiming for high throughput with minimal intervention, the combination of grade and geometry offers strong return on process stability.

Practical mounting details and assembly considerations

The insert is triangular, no hole design and therefore requires a compatible clamp style and screw for secure mounting. Correct selection of the clamping plate and torque settings is essential to prevent movement and to preserve the cutting edge. The insert belongs to the ISO turning indexable inserts family and is supplied in the TBTR form, so checking holder compatibility against the ISO code 040900 and the designation TBTR040900 avoids dimensional mismatch and facilitates quick replacement during routine maintenance.
