TECWERK Solid Carbide End Mill D4 mm — extra‑long, 4‑flute, TiAlN

The TECWERK Solid Carbide End Mill D4 mm is an extra‑long, four‑flute cutter engineered for vibration‑reduced roughing and finishing in steel, cast and non‑ferrous materials

• TiAlN coating for heat resistance
• Extra‑long 3×D cutting length
• Fine‑grain solid carbide (VHM)
• Neck relief for reduced vibration

Engineered for extended life and thermal stability

Built from fine‑grain solid carbide and finished with a TiAlN coating, this cutter provides improved heat resistance and surface hardness at elevated temperatures. The coating reduces adhesion and oxidation on the flute edges, which extends tool life in prolonged machining cycles. As a result, cycle times remain stable and regrinding intervals are extended, supporting predictable production planning. The combination of substrate and coating is chosen to balance toughness and wear resistance so that both interrupted cuts and continuous milling run reliably.

Geometry that reduces chatter and improves surface finish

The tool's unequal helix and deliberately engineered neck relief suppress resonant vibration during deep or overhanging cuts, enabling a cleaner finish with fewer re‑passes. The four‑flute layout offers a favourable compromise between chip evacuation and cutting edge engagement, while the centre‑cut geometry allows plunge milling where required. A small 45° chamfer protects the cutting edge and reduces burr formation on entry, which together deliver a consistent surface quality during both roughing and finishing operations.

Versatile material suitability for mixed production runs

This cutter is specified for universal use across a broad material spectrum: steel, stainless steels, cast irons, non‑ferrous metals and silicon‑alloyed aluminium, plus certain abrasive materials. Its 3×D cutting length provides reach for deeper slots and stepped features without sacrificing rigidity. For workshops running mixed batches, the tool reduces the need for frequent tool changes and allows efficient throughput in batch production or prototype work, aiding overall process economy and machine uptime.

Practical handling and integration in the workshop

A 6 mm cylindrical shank to DIN 6535 HB with h6 tolerance ensures concentric mounting and compatibility with standard collet chucks and toolholders. The cutter is right‑hand cutting and supplied as a single unit suitable for CNC milling machines and high‑precision manual setups. Protective chamfering at 0.07 mm and the tool's balanced design simplify handling and reduce the risk of edge damage during tool changes. Metav's application documentation and consultants can advise on feeds, speeds and clamping to match specific machine characteristics.
