TECWERK solid carbide long end mill D20 mm — 3‑flute, 38/40° helix

A TECWERK solid carbide long end mill designed for high‑feed roughing and precise finishing of aluminium, copper and other non‑ferrous metals, compliant with DIN 6527 L standards

• Solid carbide VHM construction
• Special TiAlN anti‑adhesion coating
• 3‑flute long design for deep cuts
• 38/40° helix for superior surface quality

High removal rates with consistent surface quality

The long, multi‑edge geometry combines solid carbide stiffness with an unequal helix pitch to reduce chatter and improve tool life. The 3‑flute layout balances chip evacuation and cutting engagement, enabling efficient material removal during roughing while maintaining control for subsequent finishing passes. The 38/40° helix provides a favourable cutting angle for soft and ductile materials, delivering a smoother cut face and reducing built‑up edge formation in non‑ferrous machining.

Geometry engineered for plunge and pocket operations

Centre‑cutting capability and a long effective reach allow plunge milling and deep pocketing without additional tool changes. The tool’s neck relief and protective chamfer 0.3 mm at the cutting edge protect the flute entry and extend service life when entering cavities. With an effective length 50 mm and an overall length 104 mm, this long cutter is suited for jobs that require depth access while preserving rigidity and repeatable results.

Coating and material choices that prevent clogging

The combination of VHM substrate and a TiAlN‑type special coating minimises soldering and adhesion when machining aluminium and copper alloys. This coating lowers friction, increases thermal resistance and helps preserve sharpness over longer cycles. As a result, the cutter sustains consistent cutting forces and reduces the frequency of rework, supporting predictable cycle times in production environments.

Practical fit‑up and operational compatibility

Shank dimensions comply with common toolholder standards, providing stable clamping and concentricity for high‑speed applications. The right‑hand cutting direction and centre‑cut feature make the cutter versatile for conventional milling routines. Unequal pitch on the flutes yields a vibration‑damped run, improving surface finish and extending the time between regrinds—benefits that directly impact throughput and part quality in workshop and industrial settings.

FAQ

Is this cutter suitable for full‑depth pocketing in aluminium?
The TECWERK long end mill 2000806570NW is centre cutting and designed for deep pockets in non‑ferrous metals; its long effective reach and unequal helix pitch support stable full‑depth operations in aluminium.

Can this tool be used for finishing as well as roughing?
Yes, the combination of a 3‑flute geometry and the 38/40° helix enables both effective roughing and a high‑quality finish on softer metals when feed and speed are adjusted accordingly.

What advantage does the special coating provide when machining copper and aluminium?
The TiAlN‑style special coating reduces chip adhesion and friction, helping to prevent built‑up edge and allowing longer intervals between tool changes on non‑ferrous materials.

Does the shank fit standard collets and chucks?
The cutter features a cylindrical shank designed to conform with common DIN 6535 HB interfaces, ensuring secure clamping in standard toolholders.

Why is unequal helix pitch important for surface quality?
An unequal helix pitch distributes cutting forces and interrupts harmonic frequencies, producing a quieter run and improving surface finish compared with equal‑pitch cutters.
