EPGW 040104 DX140 turning insert (PCD) for turning – Tungaloy

The EPGW 040104 DX140 is an ISO‑format rhombic turning insert with a polycrystalline diamond cutting edge, engineered for high‑speed machining of aluminium, non‑ferrous metals and abrasive non‑metallic materials.

• PCD grade DX140 for long tool life
• ISO rhombic 04 profile, 75° cutting angle
• Optimised for aluminium and non‑ferrous work
• Cylindrical hole with single‑side countersink

Exceptional productivity from polycrystalline diamond technology

The insert combines a polycrystalline diamond (PCD) cutting edge with a robust carbide body, enabling substantially higher cutting speeds and markedly longer tool life compared with conventional carbide inserts when machining non‑ferrous materials. DX140 is formulated to maintain edge stability under continuous high‑speed conditions, reducing regrind frequency and lowering cost per part. For components where surface finish and cycle time are critical, this insert supports sustained productivity and predictable tool change intervals.

Stable set‑up and interchangeability with ISO rhombic geometry

The ISO rhombic 04 format and a 75° approach angle provide predictable cutting forces and easy access for a wide range of turning tasks. Compatibility with holders is determined by form, 11° relief angle, tolerance class, fastening method, size and thickness; the insert has a thickness of 1.59 mm and a corner radius of 0.4 mm, with a cylindrical hole plus single‑side countersink (40°–60°) for secure clamping and accurate indexing. These dimensional details help engineers select the correct tooling combination to achieve repeatable results and reduce set‑up time.

Application benefits, system composition and recommended use

Designed primarily for turning, the insert performs best on aluminium, other non‑ferrous alloys and certain abrasive non‑metallic materials where PCD excels. The DIA chipbreaker geometry assists controlled chip formation; selection of chipbreaker and grade should match the workpiece material, machining method and machine stability to maximise life and surface quality. A complete tooling system comprises the ISO insert, a matching external holder or boring bar, a shim/clamp set and replacement screws, all contributing to a secure assembly that minimises vibration and improves dimensional accuracy.

FAQ

Which materials are best machined with this insert?
The EPGW 040104 DX140 turning insert is intended for aluminium, other non‑ferrous alloys and certain abrasive non‑metallic materials, where the PCD DX140 grade offers long life and excellent surface finish.

Can the insert be used at high cutting speeds?
Yes — the polycrystalline diamond cutting edge in the DX140 grade is optimised for high cutting speeds, delivering extended tool life and stable performance during sustained machining.

How is holder compatibility determined?
Compatibility depends on the insert form, relief angle, tolerance class, fastening, size and thickness; the rhombic 04 format, 11° relief and 1.59 mm thickness must match the chosen holder or boring bar to ensure secure clamping and accurate positioning.

What chipbreaker should be selected for this insert?
This insert features a DIA chipbreaker; the final choice of chipbreaker geometry and grade should correspond to the workpiece material, operation (roughing or finishing) and machine stability to ensure optimal chip control.

What components make up the complete tooling system?
A typical system includes the ISO insert, a compatible external holder or boring bar, a shim/clamp set and replacement screws; these elements together ensure correct seat, clamping and repeatable indexing for turning operations.
