20mm Solid Carbide End Mill DIN 6527L 38/40° Helix 3-Flute Long, Special Coating, 45° Chamfer - TECWERK

Take advantage of the combination of solid carbide construction, a special TiAlN anti-weld coating and an unequal helix pitch for vibration reduction to maintain high throughput and consistent surface quality; order the cutter directly via Metav Werkzeuge or consult our specialists for application advice.

TECWERK solid carbide end mill DIN 6527L — 20 mm, TiAlN-coated

The TECWERK solid carbide end mill DIN 6527L is a long, multi-flute cutter designed for efficient roughing and finishing of non-ferrous metals in demanding CNC operations.

• Solid carbide with TiAlN anti-weld coating
• 38/40° helix for controlled chip evacuation
• 3-flute unequal pitch for low vibration
• Long shank with DIN 6535 HB cylindrical shank

High-performance cutting for non-ferrous alloys

The long, multi-flute cutter is built from solid carbide and finished with a TiAlN-based special coating, which significantly reduces adhesion of chips and prevents weld deposits when machining soft, gummy materials such as aluminium and copper. The centre-cutting geometry enables plunge cuts, while the coating and carbide grade together extend tool life under raised cutting speeds. This combination yields more stable cycles and fewer interruptions in production.

Stable running and better surface finish through geometry

An unequal helix pitch combined with the 38/40° helix angle and a 3-flute layout minimises harmonic vibrations and improves surface quality on the workpiece. The varied helix reduces synchronous forces, which is especially beneficial during high-feed roughing and subsequent finishing passes. As a result, the cutter delivers consistent part-to-part quality and reduces the need for polishing or rework.

Practical design for secure clamping and deep-pocket work

Shank and mounting conform to DIN standards for a dependable hold: the cylindrical shank is specified as DIN 6535 HB and the cutter matches DIN 6527L long type design, providing long reach with controlled neck relief. A small protection chamfer (0.3 mm) and a neck relief of 19.5 mm help to avoid unintended contact in deep cavities while the 20 mm diameter and 104 mm total length permit access into recessed features. The right-hand cutting direction and centre-cut capability make the tool suitable for both roughing and finishing passes on non-ferrous components in production and toolroom environments.

FAQ

What materials is this cutter best suited for?
The TECWERK solid carbide end mill DIN 6527L (SKU 2000806570NW) is optimised for non‑ferrous metals such as aluminium and copper, offering very good performance on these materials thanks to its TiAlN coating and flute geometry.

Can the cutter perform plunge operations?
Yes. The cutter is centre cutting, so the TECWERK end mill can be used for plunge cuts as well as conventional peripheral milling, which enhances flexibility in pocketing and slotting operations.

How does the unequal helix pitch benefit machining?
The unequal helix pitch reduces synchronous vibration during cutting, resulting in a more stable run and improved surface finish, particularly beneficial when using the long version for deep or interrupted cuts.

Is the shank compatible with standard tool holders?
The cylindrical shank is specified to DIN 6535 HB, ensuring secure clamping in compatible collets and holders commonly used in CNC tooling systems.
