CNMG 090404 T9225 — CNMG ISO turning insert for turning, Tungaloy

CNMG 090404 T9225 is an ISO-standard indexable turning insert for general turning applications, designed for medium to heavy steel machining with a robust CVD-coated carbide grade.

• ISO-compliant geometry for consistent results
• CVD-coated carbide for wear resistance
• Double-sided chipbreaker for versatile cuts
• Cylindrical hole for secure clamping

Consistent cutting performance under variable conditions

The indexable insert delivers reliable cutting in mixed and interrupted cuts thanks to the T9225 CVD-coated cemented carbide grade. The coating increases surface hardness and wear resistance, which translates into longer tool life and fewer tool changes. The insert's ISO geometry ensures repeatable seat and orientation in standard holders, reducing setup time and improving process stability. For manufacturers facing fluctuating engagement or slightly interrupted cuts, this solution provides a measurable increase in uptime and predictable performance.

Secure mounting and repeatable positioning for productivity

Compatibility with standard holders is governed by form, clearance angle, tolerance class, fixation, size and thickness. The rhombic plate with a cylindrical hole and an 80° main angle gives a secure, repeatable clamping interface that supports stable cutting forces. The 0.4 mm corner radius helps to balance edge strength and surface finish, making it suitable for roughing and finishing passes when combined with the correct feed and speed. Clear ISO conformity reduces the risk of misfit and supports fast changeovers on the shop floor.

Versatile chip control and application-oriented grade

Equipped with a double-sided chipbreaker, the insert offers adaptable chip control across a range of cutting conditions. The chipbreaker geometry and the robust grade are selected to handle mid-to-heavy steel machining where toughness is required. This means fewer interrupted cuts causing edge breakage and improved surface integrity on the workpiece. Choosing the appropriate chipformer and machining parameters leads to optimised material removal rates and cost-efficiency per part produced.

Practical benefits for workshop efficiency and process security

Using a CVD-coated cemented carbide insert from a recognised range improves productivity through longer edge life and consistent geometry. The standardised ISO plate format fits common external holders or boring bars with predictable mounting, and the double-sided design offers economical indexability. For workshops seeking greater process security, the combination of coating technology, robust grade composition, and ISO standardisation supports repeatable quality and reduced downtime.

FAQ

What holders are compatible with this CNMG090404 T9225 insert?
Compatibility is determined by the ISO geometry, clearance angle, tolerance class, fixation method, size and thickness; the CNMG090404 T9225 insert fits standard CNMG-size external holders and boring bars designed for ISO turning inserts.

Is this insert suitable for interrupted cuts and variable engagement?
Yes, the T9225 grade and double-sided chipbreaker are designed to provide toughness for interrupted cuts and changing engagement conditions, making the insert suitable for medium to heavy steel machining.

Can the insert be used for finishing passes as well as roughing?
With the 0.4 mm corner radius and the correct feeds and speeds, the insert provides a balance between edge strength and surface finish that allows both roughing and light finishing operations.

Is regrinding or recoating recommended for this plate?
The CNMG090404 T9225 is intended as a disposable indexable insert; regrinding or recoating is generally not practised for this type of plate—replacement with a new insert ensures consistent ISO geometry and performance.
