DPMT11T308-MP4 WPP20G indexable turning insert — Tiger·tec Gold coating, MP4 chipbreaker (Walter Tools)

A DPMT11T308-MP4 WPP20G indexable turning insert engineered for steel machining, offering a Tiger·tec Gold coated carbide grade and a dedicated MP4 chipbreaker for stable cutting performance.

• Tiger·tec Gold coating for long tool life
• MP4 chipbreaker for reliable chip control
• Rhombic 55° insert with 0.8 mm corner radius
• Suitable for steel machining (ISO group P)

Reliable cutting edge life for efficient batch production

The combination of the Tiger·tec Gold coating and the WPP20G grade produces a coated carbide surface that resists abrasive and adhesive wear during continuous turning of steels. Designed for the thermal and mechanical conditions typical of ISO group P materials, this configuration yields predictable flank wear and longer edge life, which reduces tool change frequency and production interruptions. The result is improved overall process efficiency and lower unit costs in repetitive turning tasks.

Consistent chip control that protects the workpiece and machine

Equipped with the MP4 chipbreaker, the insert promotes controlled chip formation and evacuation at a wide range of cutting parameters. The positive geometry of the rhombic 55° shape combined with an 11° clearance angle helps maintain a steady cutting force and reduces vibration; this supports a better surface finish and repeatable dimensional accuracy. Tolerance class M ensures interchangeability and secure seating in standard toolholders, contributing to consistent part quality across production runs.

Geometry tailored for versatile turning operations

With an insert size of 11 and a corner radius of 0.8 mm, the design balances edge strength and the capacity for fine contouring. The T3 plate thickness provides sufficient rigidity for medium-duty turning tasks while allowing favourable cutting engagement in a variety of turning applications. The rhombic form enables use in internal and external turning operations where a 55° insert offers good access and visual control of the cutting edge. This geometry supports quick adaptation between roughing and finishing with minimal setup changes.

Practical selection and integration into existing tooling systems

The insert is supplied in the DPMT11T308-MP4 WPP20G designation, matching common tooling conventions for indexable turning systems and enabling straightforward replacement and inventory management. Its specification for steel (ISO group P) simplifies grade selection for mixed-production environments where multiple materials are machined. For complex applications or uncertain cutting data, technical consultation is recommended to align speeds, feeds and depths of cut with the machine and holder in use.

FAQ

What materials is this insert designed for?
The DPMT11T308-MP4 WPP20G insert is specified for machining steel and addresses the typical heat and chip-formation behaviour of ISO group P materials.

How does the MP4 chipbreaker improve machining?
The MP4 chipbreaker on this Walter Tools insert promotes controlled chip formation and evacuation, which helps maintain surface finish and reduces the risk of clogging or toolholder damage.

Is the insert suitable for finishing passes?
With a 0.8 mm corner radius and rhombic 55° geometry, the insert supports fine contouring and can be used for semi-finishing and finishing, depending on cutting parameters and machine rigidity.

What does the Tiger·tec Gold coating provide?
Tiger·tec Gold coating enhances wear resistance and thermal stability of the coated carbide, extending edge life and improving performance in continuous steel turning applications.

Can this insert be used in standard toolholders?
Yes; the DPMT11T308-MP4 WPP20G follows common ISO designation conventions and tolerance class M for compatibility with standard indexable turning toolholders.
