SNMG 120402 T6215 ISO Turning Insert by Tungaloy — CVD-coated carbide, 0.2 mm radius

SNMG 120402 T6215 is a square, double-sided turning insert designed for external and internal turning, optimised for stainless steel in stable to lightly interrupted cutting conditions

• CVD-coated carbide for enhanced wear resistance
• Suitable for stainless steel turning applications
• 0.2 mm corner radius for refined surface finishes
• ISO SNMG form with cylindrical hole for secure clamping

Extended tool life through CVD-coated carbide for steady production

The CVD-coated carbide grade offers improved resistance to abrasive and adhesive wear, which translates into longer tool life and fewer index changes. In practice this means fewer interruptions for tool exchange and a steadier production flow when machining stainless steel. The coating also helps maintain a stable cutting edge at raised temperatures; in combination with the insert geometry, this reduces flank wear and helps preserve part tolerances over longer runs.

Precision geometry and system compatibility to avoid setup issues

The insert follows the ISO SNMG standard and is supplied as a square insert, size 12 with a thickness of 4.76 mm, a 0.2 mm corner radius and a 0° clearance geometry. Compatibility with a toolholder is defined by form, clearance angle, tolerance class, fastening, size and thickness; matching these parameters ensures correct seat and clamping. The SNMG120402 design includes a cylindrical hole for secure fixation and is intended to be used with a suitable external holder or boring bar together with the required shim/clamp set and replacement screws.

Application-focused design for stainless steel with reliable chip control

The double-sided chipbreaker and the T6215 grade are selected for productive machining of stainless steel under stable to slightly interrupted conditions. The modest corner radius supports a balance between strength and surface quality: feeds that suit the 0.2 mm radius will promote consistent finish while limiting edge chipping. For interrupted cuts or less rigid setups, selecting a chipbreaker and cutting data aligned with stability and material behaviour improves process reliability and reduces the likelihood of unexpected tool failure.

Practical benefits: productivity, repeatability and simple integration

Using an ISO-conform insert reduces setup complexity and simplifies stocking of replacements across multiple machines. The combination of a robust carbide substrate, CVD coating and standard SNMG geometry supports reproducible component quality and predictable tool consumption. Integration into an existing turning system is straightforward when the holder and clamping components are verified; the result is enhanced uptime, consistent surface finishes and lower overall machining costs through reduced tool changes.

FAQ

Which materials is this insert best suited for?
The SNMG120402 T6215 insert is optimised for machining stainless steel and performs best under stable to slightly interrupted cutting conditions.

How can compatibility with a toolholder be ensured?
Compatibility requires matching form, clearance angle, tolerance class, fastening, size and thickness; check that the holder accepts ISO SNMG inserts and accommodates a 12 mm square, 4.76 mm thick insert with a cylindrical hole.

Does the insert provide good chip control for turning operations?
Yes, the double-sided chipbreaker integrated in the insert design supports effective chip formation and evacuation when paired with appropriate feeds and speeds.

What surface quality can be expected with the 0.2 mm corner radius?
A 0.2 mm corner radius offers a balance between edge strength and finish quality; when combined with correct cutting parameters the result is refined surface finishes and consistent part quality.

Is the insert indexable and suitable for multiple index positions?
The SNMG120402 is double-sided and indexable, allowing rotation to fresh cutting edges as wear occurs; this extends usable life per insert.
