DCGT070204 TH10 Tungaloy indexable insert — ISO turning insert with uncoated carbide grade TH10

DCGT070204 TH10 Tungaloy indexable insert is an ISO‑standard turning insert designed for external and internal turning applications, favouring non‑ferrous materials and situations that require low cutting forces and fine surface quality.

• ISO-compatible turning insert
• Uncoated carbide grade TH10
• Rhombic 07 form, 55° included angle
• Cylindrical hole with one-sided countersink

Consistent low cutting forces and improved surface quality

The uncoated carbide TH10 grade delivers a sharp, low‑friction cutting edge that is particularly suitable for machining aluminium, copper and brass alloys where reduced force and a clean finish matter. As an indexable insert, the geometry minimises built‑up edge and helps maintain dimensional accuracy during interrupted cuts. The single‑sided chipbreaker assists reliable chip control without coating layers that might blunt the edge; this makes the grade an economical choice for high‑volume production where repeatable surface quality and low cutting forces translate into fewer reworks and higher throughput.

Accurate seating and rapid tool exchange for stable processes

The insert conforms to ISO specifications so compatibility with holders depends on form, relief angle, tolerance class, clamping method, size and thickness. The rhombic 07 form and the cylindrical hole with single‑side countersink (40°–60°) ensure secure clamping in compatible external holders or boring bars. A 2.38 mm plate thickness and standardised dimensions facilitate straightforward replacement and minimal set‑up time, supporting stable cutting conditions and fast tool changes that reduce machine downtime and maintain production flow.

Geometry choices that balance edge strength and finish

A 0.4 mm corner radius combined with a 55° included angle provides a compromise between edge robustness and fine surface generation: the smaller radius favours better finishes and lower cutting forces, while the insert geometry preserves sufficient edge strength for medium stability cutting. The 7° relief angle reduces rubbing on the flank, lowering heat generation and extending usable edge life in appropriate applications. Selecting the correct chipbreaker and matching the grade to material and process stability will optimise component quality and tool life.

System approach for reliable turning results

The working system comprises the ISO insert plus a suitable external holder or boring bar, a proper seat or clamping set, and the correct replacement screws. Correct pairing of the insert geometry with the holder and clamping hardware ensures repeatable seating and consistent cutting conditions. For production environments seeking dependable interchangeability, the standardised format of this insert simplifies inventory management and reduces the variety of spare parts required on the shop floor.

FAQ

What materials is this insert best suited for?
The DCGT070204 TH10 Tungaloy indexable insert (SKU 6802806-Tungaloy) is optimised for non‑ferrous materials such as aluminium, copper and brass, where its uncoated TH10 grade and sharp edge produce low cutting forces and good surface finish.

How does the insert mount into a holder?
Mounting requires a compatible ISO‑type holder matched to the insert form, relief angle, tolerance and thickness; the DCGT070204 uses a cylindrical hole with a one‑sided countersink to provide secure clamping and repeatable seating.

What effect does the 0.4 mm corner radius have on machining?
A 0.4 mm corner radius balances edge strength and surface quality: it supports improved finishes and lower cutting forces while maintaining sufficient robustness for typical turning tasks when stability is adequate.

Is the TH10 grade coated or uncoated, and why does that matter?
TH10 is an uncoated carbide grade; the lack of coating keeps the cutting edge very sharp, which reduces cutting forces and helps achieve cleaner surfaces, particularly useful for non‑ferrous materials and low‑force applications.

Which parameters should be considered when selecting this insert for production?
Key parameters include the insert geometry (rhombic 07, 55°), corner radius (0.4 mm), relief angle (7°), plate thickness (2.38 mm) and the chipbreaker style; matching these to material, holder stability and cutting conditions ensures consistent performance.
