SCGT120408-MP4 WPP20G – Square 90° turning/boring insert for steel by Walter Tools

The SCGT120408-MP4 WPP20G is a square 90° indexable insert designed for turning and boring operations in steels, featuring a Tiger·tec Gold coated grade for enhanced wear resistance.

• Tiger·tec Gold coated grade WPP20G
• Designed for ISO P (steel) machining
• Square 90° form, 0.8 mm corner radius
• MP4 chipbreaker for stable chip control

Extended tool life through advanced coating technology

The coated carbide grade WPP20G, part of the Tiger·tec Gold series, combines a wear-resistant coating with a substrate optimised for the temperatures and chip forms typical in steel turning. This results in improved flank and crater wear resistance, which extends tool life and reduces changeover frequency. Coated grades are engineered to maintain cutting-edge integrity under thermal and mechanical load; in practice this means fewer interruptions to production and more consistent part quality over long runs.

Predictable geometries for accurate and repeatable results

A square 90° insert profile paired with a 0.8 mm corner radius yields a robust cutting edge that balances strength and surface finish. The modest radius enhances edge stability during heavier cuts while still enabling good surface quality in finishing passes. The 7° clearance angle reduces rubbing and helps maintain dimensional accuracy across tool life. These geometric parameters support tight tolerances and repeatable cycle times in batch production.

Controlled chips and stable processes with the MP4 breaker

The MP4 chipbreaker is tuned for chip formation in steels (ISO P), promoting short, manageable chips that evacuate reliably from the cutting zone. Stable chip control lowers the risk of chip entanglement, protects the workpiece surface and toolholder, and contributes to safer, more predictable machining. For manufacturers seeking to improve process stability, the chipbreaker design is a direct contributor to reduced scrap rates and fewer machine interventions.

Integration into production and practical advantages

The insert designation SCGT120408-MP4 follows standard indexable insert geometry, enabling straightforward integration into toolholders that accept the SCGT format. With tolerance class G and execution T, the insert provides consistent seating and repeatable indexing for multi-edge use. The WPP20G grade is primarily intended for steel machining, offering a versatile balance between wear resistance and toughness suitable for a broad range of turning tasks from roughing to light finishing.

FAQ

Is this insert suitable for stainless steel?
The WPP20G grade and SCGT120408-MP4 insert are optimised for ISO P (steel); they are not specified for stainless steel applications and performance may differ on austenitic or high-alloy stainless types.

What advantages does the Tiger·tec Gold coating provide?
The Tiger·tec Gold coating improves wear resistance and thermal stability during turning of steels, which helps extend tool life and maintain dimensional consistency in longer production runs.

How does the MP4 chipbreaker affect machining?
The MP4 chipbreaker promotes short, controllable chips in steel machining, enhancing evacuation from the cutting zone and reducing the chance of entanglement or surface damage.

Which toolholders are compatible with this insert?
The insert follows the SCGT format; it fits holders designed for SCGT120408 geometry and the corresponding clamping system—verify holder compatibility and clamping torque before first use.

Can this insert be used for finishing passes?
Yes, the combination of the square form, 0.8 mm corner radius and the WPP20G grade supports a range of operations from roughing to light finishing, depending on cutting data and machine stability.
