TECWERK solid carbide long end mill DIN 6527L, Ø12 mm, TiAlN-coated

The TECWERK solid carbide long end mill DIN 6527L is engineered for high-feed roughing and fine finishing of aluminium and other non‑ferrous metals in precision CNC work.

• Solid carbide construction for high stiffness
• Special TiAlN coating prevents material build-up
• 38/40° helix for stable chip flow and surface finish
• Three-flute geometry for high feed rates
• Optimised for aluminium and non‑ferrous alloys

High‑performance cutting with reduced build‑up

The combination of a solid carbide body and a special TiAlN coating delivers sustained cutting performance when machining sticky, soft materials such as aluminium and copper. The coating acts as a barrier to welding and adhesion on the cutting edges, which helps maintain edge integrity and extends tool life. For operations where chip evacuation and thermal stability matter, this configuration reduces the need for frequent tool changes and supports continuous production.

Designed for stable, vibration‑reduced machining

A pronounced 38/40° helix paired with an unequal-pitch three‑flute layout produces a vibration‑reduced run and steady cutting forces. This results in improved surface quality during both roughing and finishing passes. The tool’s long flute geometry provides reach in deep pockets while the unequal helix pitch helps to dampen harmonics that otherwise cause chatter, enabling reliable feeds at higher material removal rates.

Precise dimensions and compatibility for workshop setups

With a Ø12 mm shank, 83 mm overall length and 35 mm effective cutting length, this long end mill is suitable for many standard holders and extension applications. The tool features a cylindrical shank to DIN 6535 HB and a small protective chamfer for safer handling. Its right‑hand cutting orientation and three cutting edges allow for efficient chip removal and compatibility with typical CNC toolpaths and fixture arrangements.

Practical benefits for production workflows

Because the tool is optimised for non‑ferrous metals, operations benefit from predictable tool life and lower scrap rates. The three‑flute design balances rigidity with chip space, enabling faster feed per tooth than comparable two‑flute cutters while maintaining good surface finish. Where stable supply and consistent quality are essential, the tool’s construction supports reduced setup time and predictable machining cycles.

FAQ

What materials is this long end mill best suited for?
The TECWERK solid carbide long end mill (end mill, SKU 2000806568NW) is optimised for aluminium, copper and other non‑ferrous metals, offering very good suitability for these materials.

Can this cutter be used for both roughing and finishing?
Yes. The tool’s long flute geometry and three‑flute layout allow efficient roughing while the 38/40° helix and TiAlN coating support fine finishing with improved surface quality.

What are the key dimensional specifications to check for machine compatibility?
Check the Ø12 mm shank, 83 mm overall length and 35 mm effective cutting length to ensure holder and spindle compatibility with the intended CNC setup.

How does the TiAlN coating affect performance?
The TiAlN coating prevents material build‑up on the cutting edges, increases thermal resistance and helps deliver consistent tool life when machining sticky non‑ferrous alloys.
