WNMG080408 TH10 trigon indexable insert for Turning — Tungaloy

The WNMG080408-33 TH10 is an ISO-standard trigon indexable insert designed for external and internal turning, offering a sharp universal grade for non-ferrous materials and situations that benefit from an uncoated cutting edge.

ISO standard WNMG 080408 insert Uncoated carbide TH10 for non-ferrous Trigon shape with cylindrical hole 0.8 mm corner radius, 0° clearance

Accurate fit and why ISO compatibility matters

The ISO designation ensures predictable mounting and replacement: form, clearance angle, tolerance class, fastening, size and thickness determine holder compatibility. For this insert, the trigon outline and the cylindrical centre hole provide a stable seat in matching clamping systems; the specified plate thickness 4.76 mm and the ISO code 080408 must match the toolholder. For production planning, compatibility is best verified by comparing these parameters with the chosen holder specification. This reduces downtime through reliable indexing and repeatable positioning, especially in batch runs where consistent geometry is essential.

Grade behaviour and machining advantages

The TH10 grade is an uncoated carbide characterised by a sharp, universal cutting edge that lowers cutting forces and produces a clean surface finish on non-ferrous materials. Uncoated grades are particularly suitable where low friction and minimal built-up edge are priorities; they often perform well in softer alloys and in operations where coating thickness could blunt the edge. The chipbreaker 33 guides chips away from the cutting zone to support process stability, while the 0.8 mm corner radius strikes a balance between edge strength and surface quality — a modest radius that maintains a fine finish without compromising durability. These attributes translate into efficient turning where tool life and part integrity must be balanced.

System integration, handling and application notes

Integration into a turning system involves more than the insert itself: a matching external holder or boring bar, a suitable shim or clamp, and correct clamping screws form the complete system. The WNMG080408-33 TH10 insert is intended for both external and internal turning; selection of the chipbreaker and grade should be aligned with workpiece material and machining stability. The specified 0° clearance angle means the insert edge geometry must be considered when setting lead angles and approach paths to avoid rubbing. For less experienced users, a conservative feed and speed setting is recommended initially, then optimised based on surface finish and vibration behaviour. Proper storage and handling of the inserts will preserve the sharp uncoated edge and ensure consistent performance across multiple indexings.

FAQ

What materials is this insert intended for?
The WNMG080408-33 TH10 insert is designed primarily for non-ferrous materials and applications where an uncoated carbide edge supports low cutting forces and a clean surface finish.

How does the chipbreaker 33 affect machining?
Chipbreaker 33 controls chip formation and evacuation to promote stable cutting; in the WNMG080408-33 TH10 the breaker supports predictable chip flow and reduces the risk of chip re-cutting.

Is the insert compatible with standard ISO WNMG holders?
Compatibility requires a holder that matches the insert’s ISO code 080408, form, thickness (4.76 mm), hole style and tolerance class; matching these parameters ensures secure clamping and correct seating.

What does the 0° clearance angle mean in practice?
A 0° clearance angle indicates the specified relief behind the cutting edge; machining setups should account for this when selecting tool approach angles to avoid rubbing and to achieve the intended cutting geometry.

How many times can the insert be indexed?
Indexing frequency depends on wear and the chosen operating parameters; the trigon shape and cylindrical hole facilitate secure indexing, but actual reuse depends on observed edge condition and process stability.
