Slot Drill DIN 6527L Type N, Ø20 mm — Solid Carbide, TiAlN (TECWERK)

The Slot Drill DIN 6527L Type N is a long‑reach, two‑flute slotting cutter designed for centre cutting and vibration‑reduced machining across steels, cast irons and non‑ferrous alloys

• Solid‑carbide, TiAlN‑coated cutting head
• Two‑flute geometry for centre cutting
• Long effective length 50 mm for deep slots
• Cylindrical shank Ø20 mm to DIN 6535 HB

Consistent performance across demanding materials

The long‑reach solid carbide construction combined with a TiAlN surface treatment provides a reliable balance between hardness and toughness. This makes the cutter well suited to mixed production environments where one tool must handle steel, grey cast iron and non‑ferrous alloys without frequent tool changes. Thanks to the centre‑cut design and two‑flute profile, the tool enables secure plunge entry and stable slotting operations, reducing cycle time and improving process reliability for both roughing and finishing applications.

Geometry and coating engineered to extend tool life

A optimised two‑flute geometry with centre cutting capability and a dynamic pitch reduces harmonics and helps prevent chatter in interrupted cuts. The TiAlN coating increases thermal resistance and protects the cutting edges under elevated temperatures, allowing higher cutting speeds and longer tool life when machining abrasive materials or aluminium with silicon content. The 45° protective chamfer and the robust edge form support repeatable chip control, which benefits surface finish and dimensional stability during production runs.

Secure clamping and shop‑floor convenience

The cutter features a cylindrical shank to DIN 6535 HB with Ø20 mm and tolerance h6, ensuring rigid clamping in standard holders and minimal run‑out. A free relief length of 19.5 mm and an overall length of 104 mm combine to offer accessibility to recessed features while maintaining stiffness where it matters. The neck relief and long effective reach of 50 mm support vibration‑reduced engagement, making the tool a practical choice for job shops and production lines seeking fewer tool changes and dependable finishing results.

FAQ

Is this cutter suitable for plunge milling?
Yes. The Slot Drill DIN 6527L Type N is centre‑cutting and designed for plunge entry as well as slotting operations.

Which materials can be machined with this tool?
The TECWERK slot drill is suitable for steel, cast iron, Cr‑Ni (stainless) steels, non‑ferrous metals and aluminium with silicon; it also performs well on abrasive materials.

What are the shank and clamping specifications?
The tool has a cylindrical shank Ø20 mm to DIN 6535 HB with h6 tolerance, enabling rigid clamping and low run‑out.

How does the TiAlN coating affect cutting performance?
The TiAlN coating increases thermal resistance and wear protection, allowing higher cutting speeds and extended tool life, especially in dry or elevated‑temperature conditions.

Can the cutter be used for both roughing and finishing?
Yes. The geometry and coating make this long‑reach cutter suitable for both roughing and finishing passes in mixed production environments.
