TPGT 070101 SH7025 ISO turning insert for turning – Tungaloy

TPGT 070101 SH7025 is an ISO-indexed triangular turning insert designed for external and internal turning operations in standard ISO holder systems

• Triangular ISO 07 size, 60° included angle
• Coated carbide grade SH7025 for tough conditions
• 0.1 mm corner radius for fine finishing
• Cylindrical hole with single-sided countersink

Consistent edge stability for reliable production

The coated carbide composition and the SH7025 grade deliver edge stability that supports continuous machining with reduced edge chipping. The grade is engineered for toughness and wear resistance, which means the insert maintains cutting geometry under varying entry conditions. In practice, this reduces process interruptions and contributes to a steadier surface finish. The term edge stability refers to the insert's ability to retain a consistent cutting edge under fluctuating forces, which is critical for repeatable cycle-to-cycle accuracy in turning operations.

Geometry tailored for precision and surface quality

The triangular design with a 60° included angle and a 0.1 mm corner radius provides controlled cutting engagement and predictable chatter behaviour. A smaller corner radius improves surface finish while still permitting modest depth of cut; the 11° relief angle helps to avoid rubbing and supports efficient chip formation. For users unfamiliar with these parameters: the included angle determines cutting forces and insert strength, the corner radius affects finish and edge strength, and the relief angle controls clearance behind the cutting edge to prevent overheating.

Secure clamping and compact construction for tight setups

The insert's cylindrical hole with a single-sided countersink (40°–60°) ensures secure axial location and repeatable seating in compatible ISO clamping systems. With a thickness of 1.59 mm and ISO 07 size, the design is compact and suited to smaller toolholders or reduced overhang assemblies where rigidity is at a premium. Compatibility is governed by form, relief angle, tolerance class, fastening and thickness; using the correct seat and screw ensures consistent clamping force and repeatable tool positioning.

Application guidance and selection for process reliability

The one-sided chipbreaker geometry is intended for general turning; selection of a matching chipbreaker and the SH7025 sort should be based on workpiece material, machining mode and machine stability. For example, the SH7025 sort is specified for tougher conditions and changing engagement, offering a balance between wear resistance and fracture toughness. Choosing an appropriate chipbreaker improves chip control and surface integrity while extending the effective tool life, which in turn supports predictable production costs and uptime.

FAQ

What holder compatibility is required for this insert?
Compatibility is defined by form, relief angle, tolerance class, fastening, size and thickness; the TPGT 070101 SH7025 insert fits holders designed for ISO 07 triangular inserts with matching seat and clamping system.

For which machining conditions is the SH7025 grade intended?
The SH7025 grade is a coated carbide sort optimised for tougher cutting conditions and variable engagement, offering a balance of wear resistance and edge stability for turning applications.

How does the 0.1 mm corner radius affect surface finish and strength?
A 0.1 mm corner radius produces finer surface finishes and reduces built-up edge risk on light to moderate cuts; however, it is less robust than larger radii for heavy interrupted cuts, so selection should match cutting parameters.

What is the purpose of the countersunk hole design?
The cylindrical hole with single-sided countersink ensures precise axial location and repeatable clamping torque, which supports consistent insert seating and minimises movement under load.

Can this insert be used for internal and external turning?
Yes, the geometry and chipbreaker type make the insert suitable for both external and internal turning tasks when combined with the appropriate holder and cutting parameters.
