EPGT 040101 TH10 indexable insert — uncoated carbide, 75° rhombic for turning (Tungaloy)

The EPGT 040101 TH10 is an ISO‑standard rhombic indexable insert designed for general turning; its sharp, uncoated edge reduces cutting forces and supports clean surface finishes in non‑ferrous materials

• ISO‑standard rhombic 75° insert
• Uncoated carbide TH10 grade
• Single‑sided chipbreaker design
• Compatible with holders with 11° clearance

High efficiency through a sharp, uncoated grade

The focus of this insert is efficiency: the TH10 uncoated carbide grade provides a sharp cutting edge that reduces cutting forces and can produce a clean surface finish on non‑ferrous workpieces. For operations where lower cutting resistance and minimal built‑up edge are priorities, a sharp, uncoated grade frequently outperforms coated alternatives. The design is intended to deliver predictable tool life in applications such as light to medium roughing and finishing where chip control and surface quality matter.

Controlled geometry for repeatable results

Precision geometry creates the conditions for stable machining. The insert features a 75° rhombic form with a 0.1 mm nose radius and an 11° clearance angle, paired with a 1.59 mm thickness in size 04. These specifications yield a compact contact zone that supports dimensional consistency and predictable tool behaviour. The single‑sided chipbreaker helps to shape chips in a controlled manner, reducing vibration and improving turning stability when combined with an appropriate toolholder and setup.

ISO compatibility and secure mounting

As an ISO‑compliant indexable insert, compatibility with toolholders is governed by shape, clearance, tolerance class, attachment style, size and thickness. The system typically comprises the insert, a matching external holder or boring bar, and the required shim or clamp set plus replacement screws. Choosing a holder with the correct pocket geometry and clamping method ensures a secure interface, enabling repeatable seating and consistent cutting conditions throughout a production run.

Best use cases and material recommendations

This insert is optimised for turning operations on aluminium and brass and other non‑ferrous alloys, where a keen uncoated edge minimises cutting forces and avoids surface smearing. Select the single‑sided chipbreaker variant where chip evacuation in longitudinal turning is required and pair the grade with machining parameters that suit the workpiece alloy and rigidity of the setup. For less rigid configurations or interrupted cuts, consider adapting feeds and depths of cut to maintain edge stability and tool life.

Practical selection and handling advice

When selecting this insert, match the TH10 grade and chipbreaker to the workpiece material and the machine‑tool stiffness rather than relying solely on cutting speed charts. Store inserts in their original packaging to protect edges and inspect seating faces and the clamping interface before use. For detailed parameter recommendations, tooling options and application‑specific advice, technical datasheets and cutting parameter tables are available to support process optimisation and reduce trial‑and‑error at the machine.

FAQ

What materials is this insert best suited for? This insert in grade TH10 is best suited for non‑ferrous materials such as aluminium and brass; the TH10 uncoated carbide edge supports low cutting forces and good surface quality.

How does the 75° rhombic form affect turning operations? The 75° rhombic geometry of the EPGT 040101 provides a compact contact area for stable turning and good edge strength while allowing access in many external and internal turning applications.

What does the hole style mean for mounting? The cylindrical hole with a single‑side countersink (40°–60°) ensures secure clamping in compatible holders and supports repeatable seating for consistent cutting performance.

Which chipbreaker should be chosen for interrupted cuts? For interrupted or less stable cuts, select a chipbreaker and feed that favour robust chip control and avoid overloading the sharp uncoated edge; the one‑sided chipbreaker on this insert assists chip shaping in longitudinal turning.

Is an uncoated grade always preferable for aluminium? An uncoated TH10 grade is often preferable for aluminium because it reduces built‑up edge and cutting forces, but final selection should consider alloy, coolant use and machine rigidity.
