8mm Solid Carbide Long 4-Flute End Mill TiAlN Coated, 25mm Cutting Length, 45° Helix - TECWERK

Take advantage of the combination of solid carbide construction, TiAlN surface protection and a 45° helix for consistent, vibration-resistant roughing in mixed-production environments; order the end mill directly via Metav Werkzeuge or ask our consultants if needed.

End mill DIN 6527 L – NR‑UNI, Ø8 mm, TiAlN coated, solid carbide (TECWERK)

The End mill DIN 6527 L – NR‑UNI, Ø8 mm is a long, four‑flute cutter developed for robust roughing and versatile machining of steels, non‑ferrous metals and castings

• Solid carbide (VHM) for high rigidity
• TiAlN coating for extended tool life
• 4-flute design for efficient chip evacuation
• DIN 6535 HB shank, long version

Increased throughput with stable chip removal

The long, four‑edged geometry with a 45° helix and specialised roughing profile enables higher feed rates and reliable chip evacuation. This form reduces cutting forces while maintaining material removal, so the production process benefits from fewer interruptions and a lower risk of chatter. The combination of Ø8 mm nominal diameter and cutting length 25 mm provides a pragmatic balance between reach and stiffness, suitable for medium‑depth pocketing and slotting tasks in series production.

Longer service life through material and coating technology

Constructed from VHM (solid carbide) and finished with a TiAlN coating, the cutter is engineered to resist abrasive and thermal wear typical of aggressive roughing cycles. The coating increases heat resistance and reduces adhesion of workpiece material, prolonging edge life and maintaining dimensional stability over longer tool life. The tool's positive rake geometry further lowers cutting forces, which contributes directly to lower tool wear and more predictable maintenance intervals.

Precise clamping and vibration suppression for consistent results

A DIN 6535 HB shank with h6 tolerance ensures concentric clamping and minimal runout when used with standard holders, which is critical for surface finish and hole tolerances. The long version features a neck relief (neck‑ground shank) that allows deeper entry into workpieces while keeping the clamped section rigid. Together with the tool’s special roughing profile, these characteristics produce a vibration‑reduced cut and more repeatable results across batches.

Application guidance and material suitability

The cutter is optimised for general workshop and production use: very well suited for steel, non‑ferrous metals and castings, conditionally suited for stainless steels and special alloys. Its right‑hand cutting action and robust design make it a practical choice for roughing-heavy operations where stability and tool life are priorities. For guidance on feeds and speeds tailored to specific alloys or machine setups, consult the Metav Werkzeuge technical team; machining parameters should be adapted to machine rigidity and coolant strategy.

FAQ

Which materials are best suited for this end mill? This end mill (End mill DIN 6527 L – NR‑UNI, TECWERK, SKU 2000866115NW) is very well suited for steel, non‑ferrous metals and castings; stainless and special alloys are conditionally suitable.

Is the tool suitable for high‑speed machining? Yes, the VHM substrate combined with the TiAlN coating on this cutter supports higher cutting speeds and improved thermal resistance for sustained performance.

What clamping specification is required for reliable performance? A tool holder compatible with a DIN 6535 HB shank and h6 tolerance is required to ensure concentric clamping and minimise runout for the best surface and dimensional results.

Can this cutter be used for both roughing and semi‑finishing? Designed with a specialised roughing profile and a positive rake, the cutter primarily excels at roughing but can be used for semi‑finishing where material removal and tool life are priorities.

What design features reduce vibration during cutting? The combination of the 4‑flute geometry, 45° helix and the tool’s roughing profile promotes smooth chip formation and lowers the tendency to chatter, enabling vibration‑reduced machining.
