P4840P-4R-E67 WKP35S drilling and boring indexable insert — Tiger·tec Silver, for steel & cast iron (Walter Tools)

A P4840P-4R-E67 WKP35S indexable insert engineered for drilling and boring applications, optimised to deliver consistent chip control and extended wear resistance in steel and cast iron machining

• Tiger·tec Silver coating for extended life
• Optimised 4R‑E67 chipbreaker geometry
• Suited for steel and cast iron machining
• Stable edge and consistent performance

Predictable chip control for uninterrupted cycles

The specific 4R‑E67 chipbreaker is shaped to produce short, controllable chips during drilling and boring, which reduces the likelihood of recutting and machine downtime. The geometry promotes consistent chip evacuation in a range of feeds and depths, translating directly into fewer interruptions on the shop floor. Combined with the Tiger·tec Silver coating, this geometry helps maintain cutting-edge integrity and lowers tool-change frequency, supporting steady production throughput and measurable productivity gains.

Broad material compatibility with reliable wear resistance

Designed for ISO groups P and K, the grade WKP35S is a coated carbide compound tailored to the thermal and abrasive conditions typical of steel and cast iron machining. The coating decreases friction and resists abrasion, which benefits both tool life and finished-part quality. For operations that switch between unalloyed, alloyed steels and various cast irons, this insert offers a balanced performance profile, making it a pragmatic choice where versatility and predictable lifetime are priorities.

Improved process security and surface quality

A wear-resistant grade and a stable cutting edge contribute to process security and repeatable surface results in hole-making tasks. The reduced flank wear tendency of the grade minimises dimensional drift over longer runs, supporting consistent hole geometry and improved bore surface finish. In addition, the insert’s chip control characteristics reduce the need for secondary cleaning operations, which can shorten the overall machining cycle and support reliable batch consistency.
