CPGT09T304-MP4 WPP20G turning insert (Tiger·tec Gold, MP4) – Walter Tools

The CPGT09T304-MP4 WPP20G is an indexable turning insert for steel machining that combines a Tiger·tec Gold coated carbide grade with a specifically profiled MP4 chipbreaker to ensure predictable chip formation and long tool life.

• Tiger·tec Gold coated grade WPP20G
• MP4 chipbreaker for consistent chip control
• 11° relief angle for stable cutting action
• Rhombic 80° form, 0.4 mm corner radius

Higher throughput through an optimised coated grade

The Tiger·tec Gold WPP20G grade is designed as a coated carbide solution tailored for the thermal and mechanical demands of steel machining. Its coating technology improves wear resistance while preserving cut-edge toughness, which results in fewer tool changes and extended productive runtime. For process planners, this leads to a measurable improvement in machining consistency and reduced downtime. The grade is specified for the ISO P group (steel), which confirms compatibility with unalloyed and alloyed steels and supports a broad range of turning operations where both wear resistance and edge stability are required.

Predictable chip control and geometry for reliable results

The insert’s MP4 chipbreaker and rhombic 80° geometry deliver controlled chip segmentation and evacuation, reducing the risk of chip entanglement and improving surface finish stability. The 11° relief angle and a 0.4 mm corner radius balance cutting strength with edge definition: the clearance reduces rubbing while the corner radius supports a robust cutting edge, beneficial in medium- to heavy-duty cuts. As a result, workplace safety and machine utilisation are assisted by fewer interruptions and consistent part quality across shifts.

Durability and process security in daily production

Coating plus substrate combination yields a tool that is both wear-resistant and tolerant to heat peaks encountered when turning steel at elevated cutting speeds. This contributes directly to process security: fewer unexpected tool failures, repeatable surface quality and longer intervals between indexings. The insert’s tolerance class G ensures dimensional reliability for toolpath programming and workpiece conformity. For production managers, these attributes translate into a reliable baseline for cycle time estimates and quality assurance procedures.

Compatibility, selection and simple integration into tool systems

The insert is supplied in the CPGT09T304-MP4 format, thickness class T3 and ISO size 09, making it compatible with a wide range of standard insert holders that accept rhombic 80° plates. The designation confirms fitment and orientation for established toolholders; matching holders and clamping torque settings should be referenced in the machine tool or holder documentation. For applications requiring steel machining—primary ISO group P—this insert is a versatile choice for roughing and finishing passes where balanced edge life and chip control are priorities.

FAQ

What materials is this insert suitable for?
The CPGT09T304-MP4 WPP20G is designed primarily for steel machining and is specified for the ISO P material group, meaning it handles unalloyed and alloyed steels effectively.

How does the Tiger·tec Gold coating benefit production?
The Tiger·tec Gold coating on the WPP20G grade increases wear resistance and heat tolerance, resulting in longer edge life and more consistent performance during high-speed or continuous turning cycles.

What does the MP4 chipbreaker do?
The MP4 chipbreaker provides controlled chip formation and evacuation, which reduces the risk of chip build-up and aids surface finish and tool life stability in turning operations.

Is the geometry compatible with standard holders?
Yes; the rhombic 80° form and ISO designation CPGT09T304-MP4 align with common insert holders designed for rhombic plates of size 09, but holder compatibility should be checked against the toolholder catalogue.

What effect does the 0.4 mm corner radius have on parts?
A 0.4 mm corner radius improves edge strength and contributes to a stable cutting action, helping to produce consistent surface finishes while tolerating moderate interrupted cuts.
