LNHU120608-B57T WKK25G — Fräswendeschneidplatte for cast iron (Tiger·tec Gold) by Walter Tools

A LNHU120608-B57T WKK25G indexable milling insert designed for productive machining of cast iron components in industrial milling applications

• Tiger·tec Gold coating for superior wear resistance
• Optimised B57T chipbreaker for stable chips
• Rectangular insert with 0.8 mm nose radius
• Designed specifically for cast iron machining

Extended tool life through advanced coating technology

The Tiger·tec Gold coating and coated carbide substrate combine to resist the abrasive wear typical of cast iron workpieces. This coating system forms a hard, heat-resistant barrier that slows flank and crater wear, which translates into longer tool life and fewer tool changes on the shop floor. For users not specialised in coating chemistries, think of the coating as a protective skin that allows the cutting edge to maintain geometry under the high thermal and abrasive loads of cast iron machining.

Reliable chip control and consistent surface quality

The integrated B57T chipbreaker is engineered to produce short, controlled chips when machining cast iron, reducing the risk of chip entanglement and improving process stability. Combined with the rectangular geometry and the 0° (negative) rake, this insert offers a stable cutting action that supports steady material removal and a predictable surface quality. Stable chip control also reduces machine stoppages and contributes to higher productive throughput in serial production.

Geometry tuned for productive milling operations

With a 0.8 mm nose radius and a robust rectangular form, this insert provides a reliable cutting edge for a range of milling tasks on cast iron. The negative rake angle enhances edge strength, making the geometry suitable for interrupted cuts and tougher cast structures. As a direct benefit, machining cycles can be run with confidence at higher engagement depths where a regular edge might chip, thereby increasing overall productivity without sacrificing component integrity.

Clear application guidance and integration into existing processes

The grade WKK25G is specified for ISO group K (cast iron) and is balanced between wear resistance and toughness to handle the typical breaking chips of these materials. The insert designation and format fit standard toolholder systems that accept the LNHU120608-B57T family, enabling straightforward integration. For process planning, expect reliable performance in abrasive cast iron when the tool is used with appropriate cutting data; Metav Werkzeuge can advise on cutter selection and recommended parameters for optimum results.

FAQ

What materials is this insert designed for?
This Fräswendeschneidplatte LNHU120608-B57T WKK25G from Walter Tools is designed primarily for machining cast iron (ISO group K).

How does the Tiger·tec Gold coating benefit production?
The Tiger·tec Gold coating on the LNHU120608-B57G grade improves wear resistance and heat tolerance, which extends tool life and supports consistent performance in abrasive cast iron applications.

What chip behaviour can be expected with the B57T chipbreaker?
The B57T chipbreaker promotes short, manageable chips on cast iron, aiding chip evacuation and reducing the likelihood of machine stoppages due to chip build-up.

Is the insert suitable for interrupted cuts?
Yes; the rectangular shape combined with a 0° (negative) rake and a 0.8 mm nose radius gives the insert a robust edge suitable for interrupted and heavy engagement cuts in cast iron.

Can Metav Werkzeuge help with cutting data and holder selection?
Metav Werkzeuge provides application support and can recommend cutting data and compatible toolholders for the LNHU120608-B57T WKK25G to achieve optimal process security.
