P4840P-2R-E67 WKP35S – Drilling/boring indexable insert by Walter Tools (Tiger·tec Silver, coated carbide)

P4840P-2R-E67 WKP35S is a drilling/boring indexable insert designed for productive machining of steel and cast iron, offering a coated-carbide grade optimised for stable chip formation and reliable edge life.

• Tiger·tec Silver coated carbide grade WKP35S
• Optimised chipbreaker 2R‑E67 for stable chips
• Suitable for steel and cast iron machining

Stable chip control for uninterrupted machining

The insert features an optimised chipbreaker (2R‑E67) that promotes consistent chip shape and evacuation during drilling and boring cycles. Stable chip formation reduces the risk of chip jamming and tool-induced vibration, which in turn lowers downtime and improves the predictability of cycle times. The design supports continuous machining strategies and is particularly effective where repeated holemaking operations require dependable performance. By focusing on chip control, the insert contributes directly to higher productivity and reduced secondary operations for chip clearing.

A grade suited to both steel and cast iron applications

The WKP35S grade, supplied within the Tiger·tec Silver family, is a coated carbide formulation tailored for the thermal and mechanical demands of the ISO P and K groups. This means suitability for a range of unalloyed and alloyed steel types as well as cast iron, addressing the typical heat generation and abrasive wear patterns of these materials. The coating technology enhances wear resistance and reduces flank and crater wear rates, allowing shops to maintain machining quality over longer runtimes. For mixed-production environments where both steel and cast iron components are machined, this versatility reduces tool changeovers and inventory complexity.

Consistent edge life and process security

The coated-carbide substrate and advanced coating system work together to deliver repeatable cutting-edge performance under the strain of holemaking. The combination supports a robust cutting edge that resists premature wear and chipping, improving dimensional repeatability and surface finish across batches. Where process security and predictable tool life are priorities, the insert’s construction helps to reduce scrap rates and rework. Stable tool behaviour also enables confident selection of feed and speed parameters to balance productivity and component quality.

Practical advantages for workshop integration

The insert’s ISO-style designation and compact specification simplify tool management in production settings. As an indexable solution, it allows quick indexing to a fresh cutting edge without regrinding, aiding uptime and maintenance efficiency. Its geometry and grade are suited to both single-pass holemaking and repair or bore-enlargement tasks, supporting a range of machine platforms from conventional drilling rigs to CNC boring heads. Clear grade labelling and the familiar Tiger·tec Silver series designation facilitate correct tool assignment and reordering within established vendor systems.

FAQ

What materials is this insert intended for?
The insert is intended for machining steel and cast iron, with the WKP35S grade optimised for the ISO P and K material groups.

How does the 2R‑E67 chipbreaker improve drilling and boring operations?
The 2R‑E67 chipbreaker shapes and breaks chips reliably to prevent jamming, enabling smoother evacuation and reduced vibration during holemaking.

What benefit does the Tiger·tec Silver grade provide?
Tiger·tec Silver coating on the WKP35S grade increases wear resistance and edge stability, extending tool life and supporting consistent surface quality.

Is this insert suitable for CNC boring heads and conventional drills?
Yes; the insert’s geometry and indexable design make it compatible with a range of drilling and boring toolholders used in both CNC and conventional setups.

Can the same grade be used across mixed production of steel and cast iron?
The WKP35S grade is developed for both material groups, allowing reduced tooling complexity in mixed-production environments.
