TCMT 110204 AH725 triangular indexable insert for Turning — Tungaloy

TCMT110204 AH725 offers a compact, fracture-resistant geometry for general turning across a broad range of steels and rostfreier Stahl

• ISO triangular insert, 60° included angle
• PVD-coated carbide AH725 for Stahl and rostfreier Stahl
• Corner radius 0.4 mm for precise engagement
• One-sided chipbreaker, cylindrical hole + countersink

High process reliability for mixed-material turning

The combination of a PVD-coated carbide substrate and the AH725 grade is designed to deliver stable cutting behaviour when machining a variety of steels and rostfreier Stahl. The coating reduces built-up edge and improves wear resistance, which in turn extends useful edge life and reduces tooling changes. This results in a measurable improvement in process security and repeatability, particularly where workpiece materials vary or cycle times are constrained. The grade’s fracture-resistant properties make it suitable for smaller tool assemblies and situations demanding tight tolerance control.

Integration with existing tool systems minimises setup time

Compatibility is defined by the insert’s shape, clearance angle, tolerance class, fastening, size and thickness, so the insert is engineered to match standard ISO holders and boring bars. The system approach comprises the insert, the appropriate external holder or boring bar, a shim/locking set and spare screws, enabling straightforward replacement and reduced machine downtime. The ISO triangular insert form ensures interchangeability across suppliers that follow ISO standards, while the presence of a cylindrical hole with a single-sided countersink (40°–60°) secures consistent clamping forces and repeatability at each indexing cycle.

Geometry designed for stability and surface quality

The 60° included angle and corner radius 0.4 mm provide a dependable balance between edge strength and cutting engagement, helping to maintain dimensional accuracy on outer and inner turning operations. The specified clearance angle 7° reduces rubbing and heat generation on the flank face, thereby improving surface finish and lowering thermal wear on the cutting edge. The one-sided chipbreaker promotes controlled chip formation for typical turning feeds, reducing the risk of entanglement and assisting chip evacuation in both general and interrupted cuts.

Practical material and coating explanation for procurement decisions

The insert is made from carbide and supplied in the PVD-coated AH725 grade — a universal, outcrop-resistant choice for Stahl and rostfreier Stahl applications. PVD coating is applied in thin, dense layers that enhance abrasion resistance without significantly altering edge geometry, making it suitable for a wide range of cutting speeds. For buyers and process planners, the designation TCMT110204 identifies the insert geometry and size, while the AH725 grade indicates a balance of toughness and wear resistance that suits mixed-material production. This clarity simplifies specification and reduces the need for repeated trials.

FAQ

What materials is this insert suitable for?
The TCMT110204 AH725 insert is formulated as a universal, fracture-resistant grade for machining Stahl and rostfreier Stahl, offering reliable performance across mixed-material batches.

How is the insert clamped in the holder?
The insert features a cylindrical hole with a single-side countersink (40°–60°) to match standard ISO clamping arrangements; the system requires a matching holder, shim/locking set and screws for secure clamping.

What does the designation TCMT110204 mean?
TCMT defines the triangular ISO geometry and insert form; 110204 gives the size and thickness series, combined here with the AH725 grade to indicate the PVD-coated carbide specification.

Which cutting conditions benefit most from AH725?
The PVD-coated AH725 grade is beneficial where process security and resistance to chipping are priorities, such as variable material runs, smaller toolholders or operations demanding consistent surface finish.

Is the insert suitable for internal and external turning?
Yes; the triangular form and one-sided chipbreaker are suitable for both external and internal turning tasks when used with the appropriate external holder or boring bar.
