SPGN120304 TH10 — ISO turning indexable insert by Tungaloy

SPGN120304‑DIA TH10 Tungaloy insert for ISO‑standard external and internal turning applications, optimised for non‑ferrous materials and low‑force finishing operations

• ISO‑standard SPGN120304 format
• Uncoated carbide grade TH10 for low cutting forces
• DIA chipbreaker for clean surface finishes
• 11° relief with 0.4 mm corner radius

Consistent compatibility for uninterrupted production

The ISO‑standard design ensures exact fitment with compatible holders and boring bars when form, relief, tolerance class, clamping method, size and thickness are matched. As an ISO‑format indexable insert, it forms part of a modular system—insert, external holder or boring bar, shim/clamp set and replacement screws—that simplifies stocking and changeovers. This standardisation reduces set‑up times and supports predictable tool change cycles, which in turn helps maintain throughput and traceable process parameters on the shop floor.

Precise geometry for low cutting forces and fine finishes

Engineered as an uncoated cemented carbide grade, TH10 promotes low cutting resistance and minimises built‑up edge when machining aluminium, brass and other non‑ferrous alloys. The DIA chipbreaker is tailored to chip control and surface quality, while the 0.4 mm corner radius balances edge strength with the ability to achieve fine finishes. The insert’s 11° relief and 3.18 mm thickness contribute to cutting stability and secure clamping in the seat, and the square 12 mm size provides four indexing positions for economical edge utilisation.

Selection guidance to maximise process security and lifespan

Choose the insert geometry and chipbreaker according to the workpiece material, machining type and machine/tooling stability: the DIA chipbreaker suits light to medium cuts where surface finish is a priority, and the TH10 grade performs well where an uncoated edge reduces cutting forces. Match the insert to a holder with the correct form and tolerance class to avoid unintended edge loading. Regular inspection of clamping hardware and adherence to recommended cutting data will extend tool life and produce consistent results with this Tungaloy indexable insert.

FAQ

What materials is this insert best suited for?
The SPGN120304‑DIA TH10 insert is optimised for non‑ferrous materials such as aluminium and brass; the uncoated TH10 grade lowers cutting forces and helps prevent built‑up edge.

How does the DIA chipbreaker affect machining?
The DIA chipbreaker on the SPGN120304‑DIA improves chip control and supports a cleaner surface finish during light to medium cuts.

Which holders are compatible with this ISO insert?
Compatibility depends on form, clearance angle, tolerance class, clamping method, size and thickness; the insert matches standard ISO SPGN seats when these parameters align.

What does the 0.4 mm corner radius mean for finishing?
A 0.4 mm corner radius gives a compromise between edge strength and fine surface quality, suitable for semi‑finishing and finishing passes.

How many times can the insert be indexed?
The square format provides up to four cutting edges before replacement, subject to wear patterns and machining conditions.
