SNMG 120404 T9235 Tungaloy indexable insert for turning — CVD-coated cemented carbide, 0.4 mm radius

A SNMG120404 T9235 indexable turning insert designed for external and internal turning, suited to interrupted cuts and unstable machining conditions

• CVD-coated cemented carbide grade T9235
• Square ISO insert SNMG 120404, 12 mm size
• 0.4 mm corner radius for stable cuts
• Double-sided chipbreaker, cylindrical hole

Consistent machining performance for demanding steel turning

The combination of a CVD-coated surface and a cemented carbide substrate in the T9235 grade provides a dependable compromise between wear resistance and toughness. This formulation is intended for machining steel at lower cutting speeds and in situations with interrupted cuts or less rigid set-ups, where edge robustness matters more than high-speed abrasion resistance. The result is stable chip formation and fewer unexpected tool failures, which supports predictable cycle times and reduced downtime in production.

Clear compatibility and system requirements to avoid guesswork

Produced to ISO dimensions, the insert is a square, 12 mm size with a 4.76 mm plate thickness and a 0° relief angle, featuring a cylindrical hole for screw mounting. Compatibility with a holder depends on form, relief angle, tolerance class, clamping method, size and thickness; selecting a matched external holder or boring bar together with the correct shim and clamp set ensures correct seating and torque transmission. The double-sided chipbreaker extends usable edge life by enabling indexing, while the 0.4 mm corner radius balances edge strength and surface finish for general-purpose turning.

Practical selection and workshop benefits for efficient operation

For workshop planning, choose the T9235 grade and an appropriate chipbreaker when working with steel where interruptions or instability are expected; this reduces the need for frequent tool changes and helps maintain process stability. The insert integrates into a system comprising an indexable insert, an appropriate external holder or boring bar, an underlay/clamp set and replacement screws. Technical support and application data are available to specify cutting parameters and optimise feed and depth for longer tool life and consistent surface quality.

FAQ

What materials is this insert intended for?
The SNMG120404 T9235 insert is specified for machining steel, with the T9235 grade optimised for lower cutting speeds and interrupted or unstable cutting conditions.

How does the T9235 grade compare to wear-oriented grades?
T9235 is a tougher, CVD-coated grade prioritising edge strength and resistance to chipping; it sacrifices some high-speed wear resistance in favour of reliability under interrupted cuts.

Can the insert be used on both external and internal operations?
Yes, the square SNMG120404 geometry with a 90° approach is suitable for both external turning and internal turning applications when paired with the correct holder or boring bar.

What is the purpose of the cylindrical hole?
The cylindrical hole permits secure screw clamping in standard indexable insert holders, ensuring repeatable seating and simplified inventory of replacement screws.
