TECWERK long solid carbide end mill DIN 6527L D.20 mm, TiAlN, 8‑flute

A TECWERK long solid carbide end mill DIN 6527L designed for vibration‑reduced roughing and finishing in steels, castings and non‑ferrous alloys.

• TiAlN coating for high heat resistance
• Solid carbide, ultra‑fine grain microstructure
• 8 flutes for efficient material removal
• Long design with neck relief for deep cuts

Faster, more stable machining through optimised geometry

The long multi‑cut geometry combines an 8‑flute configuration with an unequal pitch and a 35–38° helix to reduce harmonic excitation and chatter. This arrangement increases axial engagement while maintaining a fine surface finish, so cycle times fall and process stability rises. The 45° protection chamfer and neck relief enable secure passes in pockets and deep cavities, delivering consistent machining results for both roughing and finishing.

Longer tool life under heat and abrasion thanks to TiAlN and VHM

Manufactured from solid carbide with an ultra‑fine grain structure and coated with TiAlN, the cutter resists thermal loading and abrasive wear even at elevated cutting speeds. The coating forms a hard, heat‑resistant layer that preserves edge integrity when machining stainless alloys and abrasive materials, translating into fewer tool changes and more predictable tool life. The result is a cost‑effective balance between performance and durability.

Secure clamping and extended reach for complex workpieces

A precision cylindrical shank to DIN 6535 HB with h6 shank tolerance ensures repeatable and secure clamping in collets and shrink fit systems, improving runout control and surface quality. With 104 mm overall length, an effective reach of 50 mm and a neck relief / free‑grind zone of 19.5 mm, the long version suits deep pockets and stepped contours while reducing the risk of collision between tool body and workpiece. The short cutting length of 8 mm concentrates cutting forces where they are most effective.

Versatile material suitability and process benefits

The cutter is optimised for a broad range of materials: steel, grey and nodular cast iron, heat‑resistant and Cr‑Ni stainless steels, as well as non‑ferrous metals and aluminium with silicon content. Because of the combination of geometry and coating, the tool performs well in both high‑feed roughing and fine finishing, enabling single‑tool strategies that simplify setups and reduce cycle times. For components exposed to abrasive inclusions the hard coating and solid‑carbide substrate deliver reliable performance where cobalt‑based tooling might struggle.

FAQ

What materials is this long solid carbide end mill best suited to?
The TECWERK long solid carbide end mill is very well suited to steel, cast iron, Cr‑Ni stainless steels, non‑ferrous metals and aluminium alloys with silicon content, as stated in the technical data.

How does the TiAlN coating benefit machining performance?
TiAlN on the TECWERK cutter provides increased thermal and abrasion resistance, which helps maintain edge life at higher cutting speeds and under demanding conditions.

Is the shank compatible with common clamping systems?
Yes; the tool's cylindrical shank to DIN 6535 HB with h6 tolerance is designed for secure clamping in standard collets and holders, ensuring low runout and repeatable positioning.

Can this cutter handle both roughing and finishing operations?
Yes; thanks to its multi‑cut geometry, unequal pitch and TiAlN coating, the cutter is suitable for vibration‑reduced roughing as well as fine finishing, enabling reduced tool changes.

What helix angle and flute count can be expected to influence cutting behaviour?
The 35–38° helix combined with 8 flutes on this TECWERK tool increases axial engagement for good surface finish while maintaining high material removal rates.
