SNMG 190612 KS20 Tungaloy indexable turning insert – ISO SNMG190612, 90° square, 1.2 mm radius

SNMG 190612 KS20 Tungaloy indexable turning insert designed for ISO-compliant external and internal turning applications with a focus on edge stability and consistent chip control

• ISO‑compliant SNMG geometry for universal holders
• KS20 grade for wear resistance and edge stability
• Double‑sided chipbreaker for controlled chips
• Square insert, 19 mm size and 6.35 mm thickness

Consistent cutting performance that extends tool life

The KS20 grade, provided by Tungaloy, is a carbide composition optimised to balance wear resistance and toughness, which translates into longer intervals between indexings and fewer unplanned tool changes. Thanks to the carbide substrate and the geometrical design, the ISO SNMG190612 form maintains cutting‑edge integrity under intermittent loads and variable cutting conditions, delivering predictable surface quality and reduced scrap rates. The result is improved throughput and lower process variability in turning cycles.

Geometry engineered for reliable chip control and stable feeds

The combination of a double-sided chipbreaker and a 0° relief angle promotes consistent chip control, particularly in routine external and internal turning tasks. Controlled chip formation reduces the risk of built-up edge and finished-surface defects while supporting steady feed rates. The central cylindrical hole and standard mounting features ensure secure clamping in compatible holders, which helps maintain axial and radial stability during machining and reduces the likelihood of chatter-related rejects.

Standardised dimensions for quick changeovers and inventory simplicity

Designed as a square insert with a nominal 19 mm side and a plate thickness of 6.35 mm, the geometry allows straightforward replacement in ISO‑compatible toolholders. The 1.2 mm nose radius and the 90° form provide a predictable contact geometry that supports consistent part tolerances and simplifies toolpath planning. Using standardised inserts minimises setup time, simplifies stock management and enables rapid recovery after tool changes, contributing to more efficient shop‑floor logistics.

Practical guidance for selection and typical use cases

Intended primarily for turning, the insert suits a broad spectrum of conventional turning tasks; the cutting performance depends on the matched chipbreaker and the chosen grade relative to workpiece conditions. For best results, pair the insert with a holder that matches form, clearance, tolerance and fastening requirements and select cutting data that reflect the material and stability of the setup. For any uncertainty regarding the correct chipbreaker or machining parameters, technical consultation is available to align grade and geometry with the production goal.
