SPMW 120404 T5115 Wendeplatten - Tungaloy

Take advantage of the combination of CVD-coated carbide and ISO-standard geometry for consistent performance in cast-iron turning; the insert’s square form and 90° cutting angle provide stable engagement and easy tool matching — order original Tungaloy inserts via Metav Werkzeuge or ask the consultants for compatibility checks.

SPMW 120404 T5115 — ISO turning indexable insert by Tungaloy for turning

SPMW120404 T5115 is an ISO-form indexable insert designed for general turning tasks, optimised for machining cast iron with a balanced wear resistance and edge stability.

• CVD-coated carbide T5115
• Universal grade for cast iron
• Square insert, 12 mm size
• 11° clearance; 90° cutting angle

Stable holder compatibility for predictable tool changes

The insert follows the ISO standard geometry, which simplifies selection and replacement across matching holders. Compatibility is governed by form, clearance angle, tolerance class, fixing method, size and thickness; this predictable system reduces setup time and helps maintain a steady production flow. Where quick reconditioning of fixtures is required, the standardised shape and the central hole with countersink provide reliable locating and clamping, reducing the risk of misalignment during high-volume turning.

Balanced CVD-coated grade for consistent wear control

The T5115 grade is a CVD-coated carbide developed as a universal solution for cast-iron machining, offering a balanced combination of wear resistance and cutting-edge stability. The chemical vapour deposition layer increases resistance to abrasion while the carbide substrate sustains the edge under interrupted cuts typical of cast-iron work. For workshops aiming to keep machining cycles steady, this grade extends tool life and helps reduce the frequency of insert changes without sacrificing surface finish.

Geometry tuned for secure engagement and repeatability

The square shape (12 mm) and the 90° cutting angle deliver a robust seat in the toolholder and allow for versatile turning operations. A 0.4 mm corner radius is suitable for general-purpose profiling and roughing where a compromise between tool strength and edge form is needed. The insert thickness of 4.76 mm and the centre hole with a single-sided countersink (40°–60°) ensure positive clamping and repeatable positioning, which together contribute to machining stability and consistent dimensional tolerances on serial parts.

Practical integration into workshop processes

Supplied as part of an ISO insert system, the package integrates with a matching external holder or boring bar, a backing shim or clamping set, and replacement screws when required. The insert is delivered without a chipbreaker, so selection of a holder with an appropriate chip control geometry or choice of cutting parameters should reflect the workpiece material and machine rigidity. For machining with varying stability or when switching between materials, the standardised insert form simplifies inventory and reduces the variety of holders needed on the shop floor.

FAQ

What materials is this insert suitable for?
The SPMW120404 T5115 indexable insert (Tungaloy, SKU 6862084-Tungaloy) is primarily intended for machining cast iron, benefitting from the T5115 grade’s balanced wear resistance and edge stability.

What does the designation SPMW120404 indicate?
The code refers to the ISO insert form and size: square form (SPMW), ISO code 120404, matching the insert’s 12 mm size and specific geometry suitable for standardised turning holders.

How is the insert clamped in the toolholder?
Clamping is achieved via the central hole and the single-sided countersink (40°–60°); this arrangement ensures secure locating and repeatable positioning when paired with the correct external holder and backing shim.

Why choose a CVD coating for this application?
The CVD coating on the T5115 grade improves abrasion resistance and helps maintain a stable cutting edge under the thermal and mechanical loads typical of cast-iron turning, extending useful tool life.

Is this insert supplied with a chipbreaker?
This variant is supplied without a chipbreaker; chip control should be provided by the chosen holder geometry or by optimising cutting conditions for the specific turning task.
