WOMX040304-B57 WKP35S Drilling/Boring Indexable Insert — Tiger‑tec Silver, for Steel & Cast Iron — Walter Tools

A WOMX040304-B57 WKP35S drilling/boring indexable insert designed for metalcutting in steel and cast iron, offering strong edge stability and consistent chip formation for production and jobbing environments

• Tiger‑tec Silver coated grade WKP35S
• Trigon 80° insert form for axial stability
• Optimised B57 chipbreaker for controlled chips
• Corner radius 0.4 mm for edge strength

Consistent wear resistance for higher uptime

The Tiger‑tec Silver coating combined with the WKP35S substrate provides a balanced resistance to abrasive wear while maintaining a sharp cutting edge. Coated carbide (described here as a hardmetal substrate with a multilayer surface treatment) helps to reduce flank wear and extend tool life under the thermal and mechanical loads typical of drilling and boring. This results in fewer tool changes, more predictable tool life and improved process stability in mixed production runs.

Geometry engineered to secure clamping and improve surface finish

The Trigon 80° form and the 0.4 mm corner radius deliver a compromise between cutting-edge strength and accessible cutting action, reducing the risk of chipping during entry and exit. The B57 chipbreaker promotes dependable chip segmentation, which simplifies evacuation and reduces the likelihood of re-cutting. Together, these features support consistent hole quality and lower secondary finishing needs, making the insert well suited to both series manufacturing and single-part production where repeatability matters.

Broad applicability across steel and cast iron with reliable tolerances

Designed for materials in ISO groups P (steel) and K (cast iron), this insert meets the demands of typical machining operations for these groups, from unalloyed to alloyed steels and grey or spheroidal cast irons. The stated tolerance class M ensures compatibility with precision toolholders and predictable positional fit. Use of this geometry and grade can improve throughput by maintaining cutting performance across varying batch sizes and material lots, while helping to deliver the surface integrity required for downstream processes.

FAQ

What materials is this insert suitable for?
The insert is intended for machining steel and cast iron; the WKP35S grade in the Tiger‑tec Silver series is optimised for ISO groups P and K and provides good wear resistance for these materials.

How does the Trigon 80° form affect performance?
The Trigon 80° geometry increases axial stability and edge strength, helping to reduce chipping during drilling and reaming while supporting a predictable surface finish.

What does the B57 chipbreaker deliver in practice?
The B57 chipbreaker promotes controlled chip segmentation for reliable evacuation and reduced risk of recutting, which improves process reliability in through‑hole and blind‑hole operations.

Is the tolerance class important for my toolholder selection?
Yes — the tolerance class M ensures consistent fit in standard toolholders and contributes to repeatable positioning and secure clamping during machining.
