S457TM Shank milling cutter — 20 mm shank, for WNMU 0403 indexable inserts (Teknik Makina)

The S457TM Shank milling cutter is a precision cutting tool designed for reliable steel machining with WNMU 0403 indexable inserts, offering a practical solution for production and repair workshops.

• Compatible with WNMU 0403 indexable inserts
• 20 mm shank for stable clamping
• Three cutting edges for efficient removal
• Lightweight 0.29 kg for easy handling

High-efficiency cutting with predictable tool life

The tool is engineered for steady metal removal rates thanks to its three cutting edges and secure insert seating. Using indexable inserts means that cutting geometry can be restored in seconds by replacing just the insert, which keeps process times low and machining quality consistent. The cutter is certified for the WNMU 0403 insert family and is compatible with ISCAR inserts, so material removal for general steel machining tasks is economical and repeatable without complex regrinding.

Stable mounting and straightforward insert fastening

A rigid connection between the toolholder and spindle is critical for surface finish and dimensional accuracy; the cutter’s 20 mm shank provides a compact, vibration-resistant interface for most toolholders. Insert clamping is secured with a Torx system (key torx T8) and a dedicated screw (M2.5x5.5), ensuring repeatable seating and minimal play. These features support stable clamping and enable a quick insert change, which reduces set-up time and supports lean production workflows.

Practical workshop benefits and manageable handling

With an overall length of 120 mm overall length and a mass of only 0.29 kg, the cutter balances reach with good tool stability in short to medium overhang applications. The light weight simplifies manual handling and tool changes, while the geometry minimises the risk of chatter in typical workshop setups. Backed by Teknik Makina, the shank milling cutter S457TM is a pragmatic choice for vendors and maintenance engineers looking for a dependable, easy-to-service indexable solution that keeps machines running.
