CCMT120412-RP4 WPP20G Drilling and Turning Indexable Insert, Tiger·tec Gold, for Steel — Walter Tools

The CCMT120412-RP4 WPP20G is a coated carbide indexable insert designed for steel machining in drilling/bore-enlarging and turning operations, delivering robust wear resistance and consistent chip control.

• Tiger·tec Gold coated carbide for durability
• Optimised RP4 chipbreaker for steel
• 7° clearance angle for reliable cutting
• 1.2 mm corner radius, rhombus 80° geometry

Proven cutting performance that extends productive uptime

The coated carbide grade Tiger·tec Gold provides a hard-wearing surface that improves edge retention and reduces flank wear under the thermal loads typical when machining steel (ISO P). By combining a modern coating technology with a stable substrate, the insert achieves longer tool life and fewer indexings, which in turn lowers machine downtime and increases parts-per-tool. The manufacturing-focused design prioritises consistent cutting behaviour; operators benefit from predictable wear progression and a usable edge for more finished cycles before replacement.

Controlled chips and consistent surface quality for fewer reworks

The RP4 chipbreaker is configured to manage the swarf behaviour associated with steel cutting, promoting short, controllable chips that evacuate reliably. Combined with the rhombus 80° geometry and a 1.2 mm corner radius, the insert supports improved surface finishes and dimensional consistency on turned or bored components. The geometry reduces the need for secondary finishing operations in many setups, delivering a measurable improvement in process efficiency and part quality.

Compact format and geometry for versatile toolholders

Configured as a CCMT-style insert with a 12 size and a 4 mm plate thickness, the format suits a broad range of standard toolholders for both drilling/bore-enlarging and turning tasks. The 7° clearance angle helps maintain cutting stability during entry and side passage, reducing rubbing and heat buildup. Tolerance class M indicates consistent manufacturing precision, which supports reproducible tool offsets and reduces setup variation across repetitive production runs.

Operational advantages that support shop-floor demands

Using a coated, modern carbide grade reduces total cost of ownership by extending edge life and enabling higher metal removal rates where appropriate. The insert’s combination of geometry and chip control produces steady cutting forces and fewer interruptions for swarf management, which contributes to a smoother production flow. For operations aiming to optimise cycle time and part consistency when machining steel, this insert delivers a straightforward route to improved process security and predictable results.
