SCMT09T304 AH725 indexable turning insert – square ISO insert for turning | Tungaloy

The SCMT09T304 AH725 is a square ISO indexable insert designed for external and internal turning, offering universal performance on steel and stainless steel where process security and fracture resistance are required.

• ISO‑standard square insert SCMT09T304
• AH725 PVD‑coated, universal, fracture‑resistant
• 0.4 mm corner radius for precise profiling
• 7° relief angle, 3.97 mm thickness

Stable process security for reliable turning

The SCMT09T304 AH725 insert is engineered for consistent chip control and repeatable results in turning applications. The PVD‑coated carbide substrate provides a balance between wear resistance and edge toughness, which reduces unexpected tool failure and contributes to steady cycle times. For production environments where material mixes occur, the universal AH725 grade helps maintain cutting stability; this leads to fewer interrupted cycles and more predictable tool changes, improving overall shopfloor efficiency.

Material versatility with focused cutting performance

Optimised for a wide range of steels including stainless variants, the grade delivers reliable behaviour across varying workpiece materials. The single‑sided chipbreaker geometry works with the insert’s edge form to shape chips for safe evacuation, reducing recutting and surface defects. For users less familiar with insert technology: the chipbreaker is a machined groove on the rake face that guides swarf away from the cutting zone, enhancing surface finish and tool life without compromising material removal rates.

Simple compatibility and secure clamping

As an ISO indexable insert, compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the square form and indexed geometry make positioning straightforward in most standard external holders and boring bars. The insert is supplied with a cylindrical hole and a single‑side countersink (40°–60°) to fit common clamping systems and ensure stable seating. Clear mechanical fitment contributes directly to reduced vibration and better concentricity, which is particularly beneficial in finishing passes.

Practical benefits: precision, repeatability and lifecycle

With a 0.4 mm corner radius and 3.97 mm plate thickness, the insert provides a good compromise between edge strength and profile fidelity for finishing and light medium turning. The 7° relief angle reduces rubbing on the flank face, lowering heat generation and improving life in interrupted cuts. Choosing a universal, fracture‑resistant grade minimises tool inventory complexity while preserving performance—ideal for shops seeking economical, predictable production rather than a large range of specialised grades.

FAQ

What materials is the SCMT09T304 AH725 suitable for?
The SCMT09T304 AH725 insert is specified for a broad range of steels, including stainless steels, and is intended as a universal, fracture‑resistant solution for turning operations.

How does the AH725 grade improve process security?
The AH725 PVD‑coated grade combines edge toughness with wear resistance to resist chipping under variable conditions, which enhances process security and reduces unscheduled tool changes.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance and clamping; the insert’s square form, cylindrical hole and countersink are compatible with standard ISO external holders and appropriate boring bars.

What cutting performance can be expected from the 0.4 mm radius?
A 0.4 mm corner radius provides precise profile control for finishing and light medium turning while retaining sufficient edge strength for interrupted cuts.

Is the insert single‑edged or double‑edged, and what is the chipbreaker type?
The insert is single‑sided with a dedicated single‑sided chipbreaker designed to produce controlled swarf and consistent surface finish in turning applications.
