SNMM190616 T9225 turning insert — 90° square, 1.6 mm radius — Tungaloy

The SNMM190616 T9225 is an ISO‑standard square indexable insert for external and internal turning, engineered for robust, medium‑to‑heavy steel machining where interrupted cuts and varying engagement require extra toughness.

• CVD‑coated carbide grade T9225
• 90° square geometry for stable cutting
• 1.6 mm corner radius for enhanced strength
• ISO compatibility with standard holders

Robust grade for demanding steel cutting

The insert features a CVD‑coated carbide body in the T9225 grade, developed for medium‑to‑heavy steel machining where alternating cutting conditions and slight interruptions demand increased toughness. The coating improves resistance to adhesion and flank wear, so the tool maintains cutting performance over longer cycles. This results in fewer changeovers and more reliable process stability, especially on setups with variable rigidity. The characteristic of stable chip formation contributes to predictable tool life and consistent component quality.

Geometry optimised for rigidity and repeatable accuracy

The square geometry with a 90° cutting edge and a 1.6 mm corner radius delivers high rigidity at the cutting zone, reducing vibration and deflection during roughing passes. The 0° clearance angle and a plate thickness of 6.35 mm give a solid mechanical interface with the toolholder, while the 19 mm plate size provides a large effective edge for heavy engagement. The centrally placed cylindrical hole ensures secure clamping with the appropriate clamp and screw set, translating into repeatable seating and concentricity across indexings.

Seamless integration into ISO turning systems

Designed as part of an ISO turning system, the insert fits into a matched assembly of a square external holder or boring bar, a backing shim or clamp kit and replacement screws. Compatibility depends on insert form, free angle, tolerance class, fastening style, size and thickness; selecting holders that match these parameters ensures correct seat and torque distribution. The single‑side chipbreaker configuration assists chip control for many steel turning tasks, simplifying process setup and improving swarf evacuation in both longitudinal and facing operations.

Practical selection advice and application notes

Choose the one‑sided chipbreaker and grade combination according to workpiece material, machining strategy and machine/toolholder stiffness: the universal T9225 grade offers a balance of wear resistance and toughness, suitable where chip control and edge security are required. For finishing passes consider reduced feeds and take advantage of the stable 90° geometry for accurate shoulder and face turning.

FAQ

What materials is this insert best suited for?
The SNMM190616 T9225 insert is optimised for steel applications, especially medium‑to‑heavy machining where toughness and stable chip formation are required.

Can the insert be used for internal turning?
Yes, the square plate geometry and robust grade make the insert suitable for both external and internal turning when paired with a compatible boring bar.

How does the T9225 grade behave under interrupted cuts?
The T9225 CVD‑coated carbide offers increased toughness and reliable chip control, making it well suited to lightly interrupted or variable engagement conditions.

Which holders are compatible with this insert?
Compatibility depends on form, free angle, tolerance class, fastening, size and thickness; select ISO‑compatible square holders or boring bars specified for 19 mm square inserts with a 6.35 mm plate thickness.

What is the advantage of the 1.6 mm corner radius?
A 1.6 mm corner radius increases edge strength and reduces the risk of chipping during heavy engagement, improving tool life for roughing operations.
