SCMT120412-RP4 SCMT120412-RP4 WPP30G Twist-drill/turning insert for steel — Walter Tools

The SCMT120412-RP4 WPP30G is a square 90° indexable insert engineered for productive steel machining, combining a Tiger‑tec Gold coating with an RP4 chipbreaker for stable chip formation and reliable tool life.

• Tiger‑tec Gold coating for high wear resistance
• Optimised RP4 chipbreaker for stable chips
• Square 90° plate with 1.2 mm corner radius
• 7° clearance angle for reliable cutting

Increased productivity through advanced coating and grade

The Tiger‑tec Gold coating paired with the WPP30G grade provides a measurable increase in wear resistance and thermal stability when machining steel. The coated carbide construction reduces flank wear at elevated cutting temperatures, which extends effective edge life and decreases tool-change frequency. For production environments where consistent cycle times and predictable regrind intervals matter, this coated grade supports stable machining with fewer interruptions. The combination of coating and grade renders the insert especially suitable for medium to heavy interrupted cuts where thermal loads and abrasive wear are typical.

Better chip control and surface integrity from geometry

The RP4 chipbreaker and the square 90° plate form with a 1.2 mm corner radius are designed to control chip form and influence cutting forces. The chipbreaker guides chip flow to avoid long, stringy chips and to promote short, controllable fragments, improving process safety at higher feeds. The 1.2 mm corner radius increases edge strength, contributing to improved surface finish and reduced risk of edge chipping in roughing and semi-finishing passes. Explained simply: a larger corner radius balances edge robustness and surface quality, while the RP4 geometry helps maintain consistent chip evacuation across a range of feeds.

Geometry and compatibility for stable turning and boring

The insert’s 7° clearance angle and the dimension set (plate size 12, thickness code 04) support predictable cutting behaviour and secure clamping in standard toolholders. The insert is offered in an execution marked T with tolerance class M, which aligns with common toolholder interfaces used in turning and boring operations. Designed primarily for steel applications, the insert integrates into established process chains and is compatible with typical CNC lathes and gang tooling setups. For integrators and production engineers, this means straightforward insertion into tool lists and uncomplicated optimisation of cutting parameters for throughput and repeatability.

FAQ

What materials is this insert intended for?
The SCMT120412-RP4 WPP30G is specified for machining steel; the WPP30G grade and Tiger‑tec Gold coating are optimised for the heat and chip behaviour typical of steel turning.

How does the RP4 chipbreaker affect machining?
The RP4 chipbreaker on this insert directs chip formation to short, controllable fragments, improving process safety and enabling higher feed rates without problematic chip entanglement.

What benefits does the 1.2 mm corner radius provide?
A 1.2 mm corner radius increases edge strength and supports improved surface finish in roughing and semi-finishing operations while reducing the susceptibility to edge chipping.

Is the insert compatible with standard toolholders?
Yes; the insert’s square 90° form and tolerance class M suit common indexable-insert holders for turning and boring. The execution code and dimensions facilitate straightforward integration into typical setups.
