DPMT 070208 T9225 Turning Insert by Tungaloy

DPMT070208 T9225 Tungaloy insert — an ISO rhombic turning insert designed for reliable external and internal turning in steel applications

• CVD-coated carbide T9225 grade
• Robust universal grade for steel machining
• Rhombic insert, size 07
• 0.8 mm corner radius for strength
• Cylindrical hole with one-sided countersink

High productivity through a balanced grade and coating

The DPMT070208 combines a CVD-coated carbide substrate with the T9225 grade to provide a balance of wear resistance and fracture toughness. This composition is aimed at medium-to-heavy steel machining where interrupted cuts or variable engagement demand a tougher grade. The coating reduces flank wear and extends tool life in batch production, which translates into fewer indexings and reduced machine downtime. The result is measurable improvement in cycle times and a stable tool life curve for repetitive turning operations.

Geometry that supports secure clamping and consistent results

A rhombic 07 form and a 0.8 mm corner radius add mechanical strength at the cutting edge, while the 55° included angle optimises cutting force distribution for turning tasks. The insert’s ISO-standard dimensions and 2.38 mm thickness make the compatibility with standard holders straightforward; however, secure clamping depends on matching form, clearance angle and size. This geometry reduces vibration sensitivity and helps maintain dimensional accuracy across production runs, supporting consistent surface quality and repeatability in component manufacture.

Versatile mounting and chip control for varied turning conditions

Equipped with hole and a cylindrical hole + one-sided countersink (40°–60°), the insert is suitable for positive axial fixing and straightforward seating in many clamping systems. The single-sided chipbreaker supports predictable chip formation in many steels, aiding evacuation and reducing heat concentration at the cutting edge. Selection of the chipbreaker and grade should follow the workpiece material, machining stability and desired surface finish. When paired with a correctly specified holder, the combination supports efficient swarf removal and longer edge life.

Practical selection and application guidance for workshops

The design and material combination emphasise productive turning where workpiece material and process stability vary. Choose the T9225 grade for jobs where toughness is required without sacrificing wear resistance. Ensure holders match the insert by form, clearance angle, tolerance class, fastening method, size and thickness to achieve the stated benefits. For interrupted cuts or semi-stable setups, this insert gives a reliable compromise between edge strength and wear performance, reducing the need for frequent tool changes and supporting throughput targets.

FAQ

What materials is this insert suited for?
The DPMT070208 T9225 insert is formulated as a robust universal grade for steel machining and performs well in medium-to-heavy turning where toughness and wear resistance are both required.

How does the grade affect interrupted cuts?
The T9225 grade offers elevated toughness compared with purely wear-focused grades, so the insert tolerates light interruptions and variable engagement better while maintaining acceptable wear rates.

Which holder factors are critical for compatibility?
Compatibility relies on matching the insert’s form, clearance angle, tolerance class, fastening method, size and thickness. Ensure the holder accommodates the rhombic 07 shape and 2.38 mm thickness.

Can the insert provide good chip control in turning?
Yes — the single-sided chipbreaker is designed to promote consistent chip formation in many steels; combined with the hole and countersink it aids secure clamping and reliable chip evacuation.

Is the insert suitable for both external and internal turning?
The ISO rhombic geometry and mounting style make the insert suitable for both external and internal turning applications when paired with an appropriate holder and stable setup.
