SPMN120308 TH10 indexable turning insert, square 12 mm, 90° for turning — Tungaloy

SPMN120308 TH10 is an ISO‑standard indexable turning insert for external and internal turning, designed for low cutting forces and clean surface finishes in non-ferrous applications.

• ISO-standardised turning geometry
• Uncoated carbide grade TH10
• Square 12 mm, corner radius 0.8 mm
• 11° clearance angle, 90° cutting corner

Product design that reduces cutting forces and improves finish

The square indexable insert delivers a reliable balance between rigidity and accessibility. Manufactured in carbide and supplied in the uncoated TH10 grade, the insert supports machining of non-ferrous materials where minimal cutting force and a pristine surface are priorities. The flat 12 mm size and 0.8 mm corner radius permit stable contact with the workpiece while offering sufficient edge strength for light to medium turning operations. Compatibility to the toolholder is determined by the insert’s form, clearance angle (11°), tolerance class, fastening method, size and thickness, ensuring predictable seating and repeatable results when matched with ISO‑compliant holders.

Practical system setup and predictable process behaviour

This ISO series is intended to be used as part of a complete system: an ISO turning insert, a matching external holder or boring bar, a shim/clamp set and replacement screws form the assembly. The insert is supplied without a chipbreaker and without a hole, so application planning should include selection of a holder that secures the insert and provides the required chip control externally. The 3.18 mm thickness contributes to insert stiffness; combined with the square form and 90° cutting corner geometry, the component yields repeatable contact conditions that support consistent surface quality and tool life under proper cutting parameters.

Material focus and selection guidance for productive turning

The TH10 uncoated grade is a sharp, general‑purpose carbide formulation intended primarily for non‑ferrous materials and situations where an uncoated cutting edge reduces cutting forces and produces cleaner surfaces. The combination of grade and geometry is particularly suited to aluminium, brass and similar alloys, where edge sharpness helps avoid built‑up edge and maintains dimensional accuracy. For unfamiliar materials or higher stability requirements, select an alternate grade or add a suitable coating as necessary; process engineers typically pair the insert with a rigid holder and optimised feeds to exploit the low cutting force characteristic while maintaining cycle times.

Reliability, economic operation and application notes

Using a standardised ISO insert simplifies inventory and holder interchangeability, which in turn reduces setup time and enhances process reliability. The uncoated edge of the TH10 grade supports predictable chip formation and surface finish in the indicated material range, while the square format provides four usable cutting corners per indexable insert, contributing to economical edge usage. Because the insert is delivered without a chipbreaker, chip evacuation and coolant strategies must be considered during fixture and tooling selection to ensure productive, stable machining cycles.

FAQ

What materials is this insert recommended for?
The SPMN120308 TH10 insert in uncoated carbide is recommended primarily for non‑ferrous materials such as aluminium and brass, where the sharp edge supports low cutting forces and clean surface finishes.

How is holder compatibility determined for this insert?
Compatibility depends on the insert form, 11° clearance angle, tolerance class, fastening method, size (12 mm) and thickness (3.18 mm); match the insert to ISO‑compliant external holders or boring bars designed for SPMN geometry.

Does the insert include a chipbreaker or hole for clamping?
This insert is supplied without a chipbreaker and without a hole; clamping is achieved via the holder’s seat and clamp system as per the ISO system design.

How many cutting edges are available per insert and what is the corner radius?
The square format provides four indexable cutting edges, each with a 0.8 mm corner radius, enabling multiple re‑indexes for economical edge usage.

Is TH10 suitable for hardened steels or pre‑hardened materials?
TH10 is an uncoated universal grade optimised for non‑ferrous materials and is not intended for machining hardened steels; for pre‑hardened or high‑hardness steels, a dedicated grade should be selected.
