Teknik Makina Shank Milling Cutter S904TM – 21 mm diameter, for WNMX 0603 indexable inserts

The Teknik Makina Shank Milling Cutter S904TM is a precision insert-mounted milling tool designed for robust material removal using WNMX 0603 indexable inserts, ideal for general machining and production setups.

• Compatible with WNMX 0603 indexable inserts
• Shaft Ø20 mm for robust clamping
• Cutting length 40 mm for deep cuts
• Two cutting edges with 90° cutting angle

Stable clamping for consistent machining results

A solid shaft diameter of 20 mm paired with a 21 mm diameter body reduces vibration and improves runout stability, which directly benefits surface finish and tool life. The tool’s two cutting edges are arranged for efficient chip removal and balanced cutting forces; this means fewer tool changes and more predictable cycle times in series production. For operations using indexable tooling, the arrangement translates into repeatable cuts and easier process parameter tuning, because insert geometry does much of the cutting work while the shank ensures positional stability.

Fast insert changes and low downtime

Designed for rapid serviceability, the cutter secures inserts with a Torx screw M2.5x5.5 driven by a T8 key, allowing quick replacement without specialised fixtures. The tool accepts WNMX 0603 inserts (Korloy-compatible), which are widely available and simplify inventory management. A cutting length of 40 mm and a 90° cutting angle enable reliable shoulder milling and face operations; the modular insert system reduces regrinding and dressing needs, improving overall workshop throughput and lowering lifecycle costs compared with solid-carbide equivalents.

Built for everyday workshop reliability

With an overall length of 150 mm and a weight of 0.379 kg, the cutter is balanced for both CNC and manual milling applications where rigidity and accessibility are important. The insert-based concept delivers versatility: different grades and coatings of WNMX 0603 inserts can be selected to match workpiece materials and surface finish requirements. This makes the tool a pragmatic choice for job shops and production lines seeking a combination of flexibility, predictable maintenance intervals and straightforward spare-part handling.
