Slot milling cutter DIN 6527L Typ N D.20 mm — TECWERK (solid carbide, TiAlN)

Slot milling cutter DIN 6527L Typ N D.20 mm is a long, solid‑carbide tool with a TiAlN coating engineered for vibration‑reduced slotting and plunge operations across steels, cast irons and non‑ferrous alloys

• Solid carbide with TiAlN coating
• Centre-cut design for plunge milling
• Long 50 mm cutting length for deep slots
• Cylindrical shank DIN 6535 HB h6 tolerance

High material removal rates with reliable surface quality

The modern cutter geometry and TiAlN coating combine to increase thermal resistance and wear life, enabling high‑performance metal removal with a consistent finish. The tool’s centre‑cut capability permits controlled plunging into workpieces, while the dynamic helix helps to evacuate chips efficiently. These technical traits translate into higher throughput and fewer tool changes during mixed production runs, making the cutter well suited to both aggressive roughing and fine finishing operations on demanding components.

Stable clamping and reduced vibration for accurate slots

Designed for vibration‑reduced machining, the tool features a neck relief and a precise shank fit to maintain concentricity in the holder. The h6 tolerance on the cylindrical shank to DIN 6535 HB ensures secure clamping and repeatable concentricity, while the neck relief reduces contact in deep slots and prevents rubbing. Together these elements minimise chatter, improve surface integrity and extend tool life, which is particularly beneficial when processing long slots or working with interrupted cuts.

Broad material range and process flexibility

The long cutting length and robust geometry make the cutter versatile across a wide material spectrum: steels, cast iron, stainless steels (Cr‑Ni), non‑ferrous metals, aluminium alloys with silicon content and abrasive components. A protective 45° chamfer (0.3 mm) guards the cutting edges during engagement, and the two‑flute design balances chip clearance with cutting stability. This versatility enables consolidation of tool inventories, reducing the need for multiple specialised cutters while maintaining machining quality across different batches.

FAQ

Is this cutter suitable for plunging operations?
Yes — the tool features a centre‑cut geometry that enables controlled plunging and makes the cutter appropriate for slotting where axial entry is required.

Which materials does the TECWERK slot milling cutter handle best?
The TECWERK slot milling cutter is rated very well for steel, cast iron, stainless (Cr‑Ni) and non‑ferrous alloys, and it is also suitable for aluminium with silicon content and many abrasive materials.

What shank tolerance and standard does the tool use?
The cutter has a cylindrical shank to DIN 6535 HB with an h6 tolerance for secure, repeatable clamping.

How does the TiAlN coating benefit machining?
The TiAlN coating improves heat resistance and wear performance, extending tool life during high‑temperature cuts and enhancing surface quality in both roughing and finishing.
