EPGT 040101 SH725 – Tungaloy turning insert, coated carbide, 75° rhombic

EPGT040101 SH725 is an ISO-design rhombic turning insert for general external and internal turning, engineered for stable cutting-edge performance under variable engagement conditions

• ISO rhombic 75° insert SH725
• Coated carbide for edge stability
• Cylindrical hole + 40°–60° countersink
• 0.1 mm corner radius, 1.59 mm thick

Reliable cutting performance for variable engagement

The SH725 coated carbide grade provides consistent edge stability even when engagement conditions change, making it suitable for shorter tools or interrupted cuts. The composition of the grade is optimised for toughness and wear resistance, which translates into fewer unplanned tool changes and more predictable cycle times. Selecting a grade that balances toughness and hardness reduces the risk of chipping and supports stable chip formation, improving process reliability and component finish.

Fast integration into ISO tooling systems and secure clamping

As an ISO-conforming rhombic insert, this item ensures straightforward compatibility with standard external holders and boring bars. The geometry—75° insert angle, 11° clearance, and a 0.1 mm corner radius—facilitates reliable positioning and repeatable results. The cylindrical hole with one-sided countersink (40°–60°) enables positive clamping with common screws and subplates, shortening fixture set-up and minimising repositioning. Clear, standardised interfaces reduce downtime when replacing inserts and support consistent batch production.

Practical application advice and system composition

Designed for turning applications, the insert features a single-sided chipbreaker that suits many general turning tasks; the correct chipbreaker and grade should be chosen to match the workpiece material and the machining stability. Typical systems comprise the insert, a matching external holder or boring bar, a shim or clamp set and replacement screws; this arrangement ensures repeatable tool location and secure fastening. If the intended workpiece material or cutting conditions are unclear, our technical team can advise on the suitable chipbreaker and cutting parameters to achieve the desired surface quality and tool life.

FAQ

What materials is this insert intended for?
The EPGT040101 SH725 insert is a coated carbide grade designed for general turning tasks; the final selection of chipbreaker and cutting data should match the workpiece material and machining stability.

How is the insert clamped in the holder?
Clamping is achieved via the cylindrical hole with a one-sided countersink (40°–60°); this geometry provides secure, repeatable seating in compatible ISO external holders and boring bars.

What does the 0.1 mm corner radius mean for surface finish?
A 0.1 mm corner radius reduces cutting forces at the edge and helps to produce a finer surface finish on turned parts, while still offering sufficient strength for many general turning operations.

Is this insert suitable for interrupted cuts?
The SH725 grade is formulated for edge stability and toughness, making it suitable for applications that involve intermittent engagement, especially when used with appropriate clamping and cutting parameters.

Which components are needed in addition to the insert for a complete tooling setup?
A complete system normally includes a compatible holder or boring bar, a shim/clamp set and replacement screws; these parts ensure correct seating and secure fastening for repeatable machining.
