EPGT 040104 TH10 – Tungaloy indexable insert for turning (rhombic, 75°)

The EPGT040104 TH10 is an ISO‑format indexable insert for external and internal turning, designed to deliver low cutting forces and clean surfaces on non‑ferrous materials.

• ISO rhombic insert EPGT 040104, 75° cutting angle
• Uncoated carbide TH10 for low cutting forces
• Single-sided chipbreaker for clean surface finish
• Cylindrical hole + 40°–60° countersink for secure clamping

Consistent turning with a sharp uncoated grade

The TH10 uncoated carbide grade is specified for applications where a sharp cutting edge reduces cutting forces and promotes clean surface finish when machining non‑ferrous workpieces. The uncoated edge lowers friction at the cutting zone, which can translate into reduced power demand and more stable process behaviour when cutting softer alloys. As an ISO‑standard insert, the component supports predictable interchangeability across compatible holders, simplifying tool inventory and replacement procedures while maintaining process repeatability.

Geometry that balances finish and stability

The rhombic form with a 75° included angle and a 0.4 mm nose radius is engineered to offer a compromise between edge strength and surface quality: the modest nose radius helps achieve fine finishes while preserving adequate edge resilience for routine turning tasks. The insert features an 11° relief (clearance) angle and a plate thickness of 1.59 mm, which together contribute to stable seating in the toolholder and consistent cutting engagement. The presence of a cylindrical hole with a one‑sided countersink (40°–60°) ensures reliable clamping and precise location when mounted in the correct ISO‑format holder.

System approach and practical application guidance

This insert is intended for turning — both external and internal operations — and should be used as part of a matched system comprising an appropriate external holder or boring bar, shim/clamp set and replacement screws. Selection of the single‑sided chipbreaker should be matched to the workpiece material and the required machining stability: choose a chipbreaker that promotes chip control for the given cut depth and feed rate. Where quieter cutting and a cleaner surface are priorities, the TH10 uncoated grade is a practical choice for many non‑ferrous applications; for different materials or higher thermal loads, a coated grade may be considered instead.

FAQ

Which materials is this insert best suited for? The EPGT040104 TH10 is tuned for non‑ferrous materials; the TH10 uncoated carbide grade supports lower cutting forces and yields cleaner surface finishes when machining such alloys.

How is compatibility with toolholders ensured? Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness; the EPGT040104 format requires a holder designed for ISO rhombic 04 inserts with a 75° included angle.

What does the 0.4 mm nose radius mean for part finish and edge life? A 0.4 mm nose radius offers a balance between surface finish and edge strength: it helps produce finer surface quality than a larger radius while still providing reasonable resistance to breakage under normal turning conditions.

Can the insert be used for internal turning operations? Yes; the insert is specified for both external and internal turning, provided an appropriate boring bar or internal holder with sufficient clearance and correct seating is used.

Is the insert coated? No — the EPGT040104 TH10 is an uncoated carbide insert (TH10 grade), chosen for applications where a sharp, uncoated edge is advantageous.
