WCMT040204-E47 WPP20G Drilling/Boring Indexable Insert, Tiger·tec Gold – for steel

WCMT040204-E47 WPP20G is a drilling and boring indexable insert engineered for robust performance in steel machining applications.

• Tiger·tec Gold coated carbide grade WPP20G
• Designed for machining steel (ISO P)
• 80° trigon geometry for stable cutting
• 0.4 mm corner radius with E47 chipbreaker

High-performance grade for reliable metal removal

The WCMT040204-E47 WPP20G belongs to the Tiger·tec Gold coating family and is manufactured as a coated carbide insert to withstand the thermal and mechanical demands of steel cutting. The WPP20G grade is formulated to deliver improved wear resistance and stable chip formation, which translates into fewer interruptions for insert changes and a lower cost per component. For production environments where repeatability matters, the coated carbide technology supports consistent machining behaviour across runs, enabling tighter process control and predictable life cycles.

Geometry that stabilises cutting and improves surface quality

The insert’s 80° trigon outline and 7° clearance combine to provide a stable cutting interface that resists deflection during drilling and boring operations. The 0.4 mm corner radius increases edge strength while the E47 chipbreaker is shaped to control chip flow from typical steels, helping to avoid clogging and protecting the cutting edge. These geometric choices result in a more consistent surface finish and reduced risk of edge chipping, making the insert suitable for demanding component tolerances where surface integrity is essential.

Economical machining with predictable tool life

Selecting a WPP20G grade insert for steel (ISO P) supports a balance between toughness and hardness, which is beneficial when machining a wide range of unalloyed and alloyed steels. The combination of the Tiger·tec Gold coating and the insert’s geometry reduces wear rates and helps maintain a repeatable cutting edge, so throughput can be increased without compromising part quality. Process planners will find that predictable insert behaviour assists with cycle-time optimisation and reduces unplanned downtime, contributing to measurable savings over production batches.

Choosing and integrating the insert into the process

The insert is supplied in the WCMT040204-E47 format with the E47 chipbreaker and is compatible with holders designed for the trigon 80° form. Its specification suits conventional drilling and boring tool bodies that accept indexable inserts of this family; selection of appropriate cutting data and clamping torque will further enhance process security. Walter Tools’ reputation for precision tooling underpins the design intent: consistent results, long tool life and reliable performance in steel-focused applications.
