TCMT110204-FK6 WKK20S — Triangle 60° turning insert for cast iron, Tiger·tec Silver — Walter Tools

TCMT110204-FK6 WKK20S is a triangle‑form indexable insert designed for turning and boring applications in abrasive cast iron environments, delivering stable chip formation and long tool life.

• Tiger·tec Silver coating for durability
• Optimised for cast iron machining
• Triangle 60° insert form
• 0.4 mm nose radius for fine finishing

Consistent chip control that reduces rework

The geometry and the FK6 chipbreaker are engineered to manage the short, brittle chips typically produced by cast iron. Controlled chip formation minimises the risk of surface damage and tool interruptions, which translates into more predictable cycles and fewer secondary operations. For operators unfamiliar with chipbreaker design: the FK6 profile directs and fractures chips reliably, improving evacuation in both stable and interrupted cuts and helping to maintain surface integrity.

Coated carbide grade that extends productive time

Belonging to the Tiger·tec Silver family, the WKK20S grade is a coated carbide formulation optimized for abrasive wear encountered when machining cast iron. The coating provides enhanced thermal and wear resistance, so the insert keeps a sharper, usable edge for longer periods. For production planners, this means fewer insert changes per shift and a smoother production flow, supporting consistent component tolerances without frequent tool adjustments.

Geometry tuned for precision and repeatability

With a triangle 60° form and a 0.4 mm nose radius, this insert balances strength and finish capability. The relatively small nose radius enables fine finishing passes and consistent dimensional control on interrupted surfaces, while the triangular shape provides three usable cutting edges, contributing to cost efficiency per insert. The specified 7° relief angle reduces rubbing and heat at the cutting edge, supporting stable cutting conditions and repeatable outcomes.

Practical advantages for workshop integration

The insert’s standard designation and dimensions follow common tooling conventions, allowing straightforward toolholder selection and fast replacement. The insert comes in execution code T with tolerance class M, facilitating interchangeability in established tool systems. Shops aiming to streamline tooling logistics benefit from the clear classification and the insert’s versatility within cast iron operations, reducing procurement complexity and setup time.

How it supports quality and throughput

By combining wear‑resistant coating, targeted chip control and robust geometry the insert helps to raise first‑pass yields on cast iron components. The result is measurable: fewer interrupted cuts, reduced scrap due to surface defects and a lower frequency of tool changes. For manufacturing engineers, the net effect is improved cycle‑time stability and a predictable maintenance rhythm for cutting equipment.

FAQ

What types of cast iron are suitable for this insert?
This TCMT110204-FK6 WKK20S insert is optimised for a broad range of cast iron grades; the WKK20S grade is targeted at abrasive, breakage‑prone chips typical of many grey and nodular cast irons.

Can the insert be used for finishing passes?
Yes. The 0.4 mm nose radius and the triangle 60° geometry enable fine finishing and consistent dimensional control when using appropriate feeds and speeds with the TCMT110204-FK6 WKK20S by Walter Tools.

How does the Tiger·tec Silver coating benefit production?
The Tiger·tec Silver coating on the WKK20S grade increases thermal and wear resistance, extending edge life and supporting longer uninterrupted production runs with Walter Tools inserts.

Is this insert compatible with standard triangular turning toolholders?
The insert follows common triangular insert dimensions and can be mounted in compatible holders designed for TCMT inserts; ensure the correct clamping and seat geometry for secure positioning.

What is the main advantage of the FK6 chipbreaker?
The FK6 chipbreaker on this insert promotes consistent fragmentation and evacuation of short, brittle chips in cast iron machining, reducing the risk of surface damage and tool interruption.
