CCMT09T312-MW4 WPP20G — Turning insert, Tiger·tec Gold, for steel | Walter Tools

The CCMT09T312-MW4 WPP20G is an 80° rhombic turning insert with a 7° clearance angle and a robust chipbreaker, designed for general steel turning applications where a balance of wear resistance and toughness is required.

• Tiger·tec Gold coating for longer tool life
• WPP20G grade optimised for steel machining
• MW4 chipbreaker for reliable chip control
• 80° rhombic geometry with 1.2 mm corner radius

Increased process efficiency through advanced coating and grade

The combination of Tiger·tec Gold coating and the WPP20G graded substrate provides a coated cemented carbide construction engineered for turning steel. The multilayer wear coating reduces flank wear and thermal loading, which extends tool life and lowers tooling costs per component. For workshops aiming to raise throughput while keeping machining stable, this coated grade offers a measurable improvement in durability without sacrificing cutting-edge toughness.

Consistent chip control and improved surface finish

The MW4 chipbreaker and the 80° rhombic geometry work together to ensure controlled chip formation and evacuation during turning. The modest 7° clearance angle supports secure cutting edge engagement, while the 1.2 mm corner radius adds mechanical strength at the cutting tip. These geometry choices help produce repeatable surface quality and reduce the risk of unexpected tool damage, especially in interrupted cuts and varying feed conditions.

Easy integration and high process reliability

Designed to match standard CCMT toolholder systems, the CCMT09T312-MW4 designation ensures straightforward replacement and positioning in existing setups. With a T3 thickness and tolerance class M, the insert delivers consistent indexability and predictable repeatability in production. Walter Tools’ manufacturing standards contribute to process security and consistent performance for general-purpose turning of unalloyed and alloyed steels in accordance with ISO group P.

FAQ

Which materials can be machined with this insert?
The CCMT09T312-MW4 WPP20G insert is specified for steel applications (ISO group P), covering unalloyed and alloyed steels with typical heat and chip formation characteristics.

What does the WPP20G grade offer?
WPP20G denotes a Walter Tools grade within the Tiger·tec Gold family: a coated cemented carbide composition that balances wear resistance and toughness for general steel turning.

How do the geometry and chipbreaker affect performance?
The 80° rhombic shape combined with a 1.2 mm corner radius, 7° clearance and the MW4 chipbreaker promote stable cutting, consistent chip control and improved surface finish under typical turning conditions.

Is this insert suitable for finishing or roughing operations?
As a universal grade, WPP20G offers a compromise between wear resistance and toughness, making the insert suitable for finishing and light to medium roughing in steel; heavy roughing may require a more robust grade.

Will the insert fit standard CCMT toolholders?
Yes. The CCMT09T312-MW4 ISO designation corresponds to common CCMT toolholders and clamping systems; proper seating and clamping torque should be observed for reliable performance.
