TCGT080202 SH725 Tungaloy indexable turning insert — coated cemented carbide, 0.2 mm corner radius

The TCGT080202 SH725 is an ISO-standard triangular indexable insert for turning, engineered for variable engagement conditions and particularly suited to small tools and changing cutting depths.

Coated carbide SH725 for stable cutting performance
Triangular ISO insert, size 08, 7° clearance angle
Corner radius 0.2 mm for fine finishing
Cylindrical hole with single-sided countersink 40°–60°

High-accuracy edges for consistent surface finish

The triangular geometry with a 60° included angle and a 0.2 mm corner radius delivers predictable contact conditions at the tool tip, which helps to maintain a uniform surface quality during light to moderate cuts. A small corner radius reduces radial cutting forces and limits vibration on less rigid setups, yielding better dimensional control. The function of a corner radius is to disperse cutting loads across a defined edge radius rather than a single sharp point, thereby improving edge life and contributing to reliable finishing in serial production.

Durable grade for variable engagement and small-tool use

The SH725 grade is a coated cemented carbide designed for toughness and cutting-edge stability under fluctuating entry conditions. This composition supports performance where chip load, depth of cut and engagement angle vary from pass to pass, a common situation with small-diameter holders or interrupted cuts. The coating improves wear resistance while the substrate toughness reduces edge chipping, offering a balance between productivity and tool life that is particularly valuable in workshops seeking repeatable results without frequent index changes.

ISO compatibility and fast indexability to reduce downtime

Being an ISO-standard TCGT insert, the component is compatible with a wide range of external holders provided the holder matches the insert form, clearance, tolerance class, fixation, size and thickness. The 7° clearance angle and the cylindrical hole with single-sided countersink (40°–60°) ensure secure clamping and repeatable seating, which simplifies index changes and reduces setup time. A one-sided chipbreaker assists chip control for turning operations, meaning fewer interruptions for chip clearing and a smoother machining cycle.

Practical setup guidance and recommended applications

The insert forms part of a system comprising the indexable insert itself, a matched external holder or boring bar, a locating shim/clamp set and replacement screws. Typical uses are external and internal turning, where the choice of chipbreaker and grade should match the workpiece material and stability of the machining arrangement. For interrupted cuts, small-diameter tooling or operations with varying engagement, the combination of SH725 and the triangular form provides robustness; for heavy continuous cuts, consider a more wear-focused grade or a larger radius where appropriate.

FAQ

What machining tasks is this insert intended for?
The TCGT080202 SH725 insert is designed for turning operations, covering both external and internal turning where varying engagement conditions or small-tool setups occur.

How does the SH725 grade affect performance?
SH725 is a coated cemented carbide grade that prioritises edge stability and toughness, improving resistance to chipping during interrupted cuts and offering longer edge life in variable engagement scenarios.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance, tolerance class, fixation method, size and thickness; the ISO-standard TCGT geometry ensures broad compatibility with appropriately specified external holders and boring bars.

What is the advantage of the 0.2 mm corner radius?
A 0.2 mm corner radius reduces peak cutting forces and helps achieve finer surface finishes on less rigid setups, while also spreading load to prolong edge life compared with a very sharp corner.

Does the insert include a hole and countersink for clamping?
Yes — the insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to ensure reliable seating and clamping in compatible holders.
