CCMT120404-MP4 WPP20G — Turning insert CCMT120404-MP4 WPP20G by Walter Tools, Tiger·tec Gold, Rhombic 80°

CCMT120404-MP4 WPP20G is a coated carbide turning insert designed for general steel applications, offering a balanced combination of wear resistance and toughness for stable machining

• Tiger·tec Gold coating for extended life
• Optimised MP4 chipbreaker for controlled chips
• Suited to ISO P steels for versatile turning
• Rhombic 80° form for adaptable cutting angles

Consistent wear resistance for productive turning

The Tiger·tec Gold coating and the WPP20G grade provide a balanced response to heat and abrasion, which results in consistent wear resistance across longer tool life. Coated carbide combines a hard, wear-resistant outer layer with a tough substrate to resist fracture; this means fewer index changes and improved uptime. For operations on ISO P materials (unalloyed and alloyed steel), the insert delivers stable performance even where temperature and chip formation vary.

Controlled chip formation for safer, faster machining

Equipped with the MP4 chipbreaker, the insert is engineered to produce predictable chip shapes that evacuate reliably from the cut. Controlled chips reduce the risk of entanglement and help to maintain surface finish, enabling higher feed rates where process stability permits. The Rhombic 80° geometry supports a wide range of turning tasks, from light finishing to medium roughing, making the insert a practical choice for batch runs or mixed-production shops.

Geometry and tolerances that support repeatable accuracy

The CCMT geometry with a 0.4 mm corner radius and a 7° relief angle offers a compromise between edge strength and the ability to achieve fine surface finishes. The tolerance class M ensures consistent insert seating and repeatable tool offsets, which simplifies tool set-up and helps maintain dimensional accuracy across assemblies. Where interrupted cuts or variable chip loads occur, the coated carbide substrate helps to absorb impact while the coating limits flank wear.

Practical benefits for workshop logistics and process planning

Familiar insert designation and industry-standard format reduce the need for special tooling adaptations. The CCMT120404-MP4 series integrates easily into existing toolholders and tool life planning, helping to streamline inventory management. With predictable wear characteristics, planning for regrinding or replacement becomes more straightforward, contributing to efficient process control and reduced downtime.

FAQ

What materials is this insert suitable for?
This insert is specified for ISO P applications; the Walter Tools CCMT120404-MP4 WPP20G grade is optimised for machining unalloyed and alloyed steel.

How does the MP4 chipbreaker affect machining?
The MP4 chipbreaker on the CCMT120404-MP4 insert promotes controlled chip formation and reliable evacuation, which supports higher feed rates and improved surface finish in many turning operations.

Can this insert be used for both finishing and roughing?
Yes, the Rhombic 80° form and the balanced WPP20G grade make the insert suitable for light finishing and medium roughing on steel, offering flexibility across common turning tasks.

What does the WPP20G grade provide compared with other grades?
WPP20G, part of the Tiger·tec Gold family, delivers a compromise between wear resistance and toughness, enabling longer tool life under variable thermal and load conditions typical for steel machining.

Is the corner radius of 0.4 mm suitable for fine surface finishes?
A 0.4 mm corner radius provides a good balance: it reinforces the cutting edge for stability while still allowing the achievement of fine surface finishes when appropriate feeds and speeds are selected.
