CCMT120412-E47 WPP20G — Drill / Boring indexable insert, Tiger·tec Gold coating, Rhombus 80° — Walter Tools

A CCMT120412-E47 WPP20G is a drilling and boring indexable insert designed for demanding steel applications, combining a coated carbide grade with an E47 chipbreaker and rhombic geometry for stable, repeatable machining.

• Tiger·tec Gold coated for longer life
• Optimised for steel machining (ISO P)
• Rhombic 80° geometry for stable cutting
• 1.2 mm corner radius for durable edge

High productivity for steel: coating and grade that pay off

The combination of the Tiger·tec Gold coating and the WPP20G grade delivers a measurable advantage when machining steels (ISO P). The coating reduces flank wear and improves thermal resistance, which leads to longer tool life and fewer indexings in production cycles. For process planners this means greater machine uptime and a better cost‑per‑part ratio, while operators benefit from more predictable tool change intervals and consistent surface finishes.

Better chip control and reliable cutting forces

Equipped with the E47 chipbreaker, the insert channels chips away from the cutting zone and helps to maintain a steady cutting force. The chipbreaker design reduces the likelihood of clogging and supports uninterrupted chip evacuation during drilling and boring tasks, which is particularly important when working with long or heavy sections of steel. For those less familiar with chipbreaker functions: it is a micro‑geometry on the rake face that shapes chip formation to improve safety and surface quality.

Geometry and edge strength for precise bore enlargement

The rhombic 80° profile and the 7° relief angle provide a robust seating in the toolholder and predictable cutting directions for bore enlargement and drilling operations. The 1.2 mm corner radius increases the edge strength and reduces chipping under intermittent cuts or varying feed rates. This geometry supports dimensional stability and repeatability, which is essential for operations where concentricity and hole tolerance matter.

Practical application and process guidance

This indexable insert is specified for steel machining and is available in the Tiger·tec Gold series for a balance of wear resistance and toughness. Selection of the insert influences feeds and speeds: the WPP20G grade favours higher cutting speeds with reliable wear behaviour. For integration into existing tool systems, ensure the insert seat and clamping are compatible with CCMT format holders and confirm the thickness code and size match the holder specifications.

FAQ

What materials is this insert suitable for?
The insert is specified for machining steels; the WPP20G grade and Tiger·tec Gold technology are optimised for ISO P materials.

How does the E47 chipbreaker affect machining?
The E47 chipbreaker promotes controlled chip formation and evacuation, improving surface quality and reducing the risk of chip congestion during drilling and boring.

What benefit does the rhombic 80° geometry provide?
The Rhombus 80° geometry offers stable clamping and predictable cutting directions, which helps maintain dimensional accuracy in bore enlargement tasks.

Is the corner radius of 1.2 mm suitable for heavy cuts?
A 1.2 mm corner radius increases edge strength and is beneficial for intermittent or heavier cuts, contributing to reduced chipping and longer edge life.

Can Metav Werkzeuge supply cutting data for this insert?
Supplier guidance on feeds and speeds for the CCMT120412-E47 WPP20G can be provided by Metav Werkzeuge to match the application and machine capability.
