TCMT090208-RP4 WPP20G – Triangular 60° indexable insert for steel machining (Walter Tools)

TCMT090208-RP4 WPP20G is a triangular indexable insert designed for drilling, bore-enlarging and light turning in steel applications, optimised for reliable chip control and repeatable results.

• Tiger‑tec Gold coated carbide
• Optimised for steel machining
• 60° triangular form for stable cuts
• 0.8 mm corner radius for versatility

High-performance grade for productive steel machining

The insert employs the WPP20G grade within the Tiger‑tec Gold family, a coated carbide designed for the thermal and mechanical demands of steel (ISO P). This coating technology combines wear resistance with a controlled edge toughness to extend cutting life under mixed cutting conditions. For production shops this translates into consistent surface finish, longer tool life and fewer tool changes, which contributes directly to higher machine utilisation and lower unit costs.

Geometry engineered for stability and chip control

The triangular 60° form and 0.8 mm corner radius provide a balance between strength and accessibility in transitional operations. The 7° relief angle reduces rubbing at entry and exit while keeping the cutting edge engaged under radial loads. The RP4 chipbreaker supports controlled chip formation when machining unalloyed and alloyed steels, lowering the risk of built-up edge and promoting continuous machining in automated or manual setups.

Economic benefits from material and design choices

Built from coated carbide, the insert is suitable for the heat and chip characteristics of steel and offers good wear resistance in general-purpose applications. The WPP20G grade is positioned as a universal to wear‑resistant option, allowing fewer tool variants across mixed steel batches. Fewer tool changes and predictable wear behaviour improve throughput and reduce process interruptions, delivering a measurable return in high-mix or high-volume environments.

Practical fitment and application guidance

The insert designation, TCMT090208-RP4 WPP20G, matches standard indexable insert sizes and fits compatible triangular toolholders for drilling and finishing passes. The plate thickness and 09 size make it suitable for medium to light-duty turning and bore finishing where a combination of rigidity and edge life is required. For best results, select cutting parameters aligned to the workpiece steel grade and machining strategy; the RP4 chipbreaker aids in keeping chips compact and evacuable in common machining set-ups.
