SCGT120408-MN2 WNN10 — Turning indexable insert, square 90°, MN2 chipbreaker (Walter Tools)

The SCGT120408-MN2 WNN10 is a square 90° turning insert in coated carbide, designed for general turning tasks where predictable chip control and repeatable edge life are required

• Coated carbide cutting grade WNN10
• MN2 chipbreaker for consistent chips
• Square 90° form with 0.8 mm radius
• 7° clearance and 04 thickness

Predictable cutting performance with optimised chip control

The insert combines a coated carbide grade with an engineered MN2 chipbreaker, delivering controlled chip formation and steady cutting forces. The square 90° geometry and 0.8 mm corner radius provide a balance between edge strength and cutting precision, making the component suitable for a range of turning tasks. Material suitability should be verified against the official product matrix; the cutting grade is intended for versatile use across many workpiece families when matched correctly. By highlighting repeatability and consistent chip evacuation, the design reduces the need for frequent intervention while maintaining surface integrity on the workpiece.

Increased process stability and extended tool life

A modest 7° clearance limits flank rubbing while preserving the active cutting edge under varying feed conditions. The plate thickness (04) and square format promote rigidity in the toolholder, which in turn reduces vibration and supports longer tool life. The coated surface of the grade enhances wear resistance and contributes to a steadier flank wear progression, helping to maintain dimensional accuracy over longer cutting runs. This focus on process stability benefits production environments that require consistent cycle times and a reliable component finish.

Practical selection and integration guidance for workshop use

The insert is supplied in the standard SCGT contour and bears the designation SCGT120408-MN2 WNN10, making it directly compatible with toolholders designed for SCGT-style plates. The MN2 chipbreaker is optimised for general turning operations; however, selection should be guided by the cutting data sheet and the product matrix to ensure correct matching to workpiece material and cutting conditions. Indexable inserts of this format allow for simple rotation to a fresh cutting edge, reducing tooling downtime and improving cost-efficiency per edge. For bespoke machining strategies or uncertain material classes, technical consultation is recommended.

FAQ

What materials is this insert suitable for?
Material suitability must be checked in the official product matrix; the SCGT120408-MN2 WNN10 is a coated carbide grade designed for broad application, but specific performance depends on the matched workpiece material.

How does the MN2 chipbreaker affect machining?
The MN2 chipbreaker on the insert promotes short, controlled chips and stable cutting forces, which supports consistent surface finish and reduces interruption from long, stringy chips when the cutting data are applied correctly.

Can this insert be rotated to a fresh edge during production?
Yes, the square 90° format of the SCGT120408-MN2 WNN10 allows multiple usable edges; indexed rotation reduces tool change frequency and improves cost-efficiency per edge.

What is the effect of the 0.8 mm corner radius?
The 0.8 mm corner radius increases edge robustness compared with a smaller radius, enhancing resistance to chipping and improving dimensional stability under intermittent cuts or heavier feeds.

Which toolholders accept this insert geometry?
Holders designed for SCGT-style inserts are compatible with the SCGT120408-MN2 WNN10; correct clamping and seat conformity are essential to achieve the stated process stability.

Is the grade suitable for finishing operations?
The coated grade and controlled chipbreaking behaviour support good surface quality; final suitability for finishing should be validated against the cutting parameter recommendations and the product matrix.
