4mm Solid Carbide End Mill TiAlN Coating 45° Helix 4 Flute Long Shank DIN 6527 - TECWERK

Take advantage of the combination of high tool stability, multilayer TiAlN wear protection and a 45° helix for smooth chip evacuation and consistent surface quality; order the cutter directly via Metav Werkzeuge or consult our technical advisers for application advice.

End mill DIN 6527L Type NF-UNI – 4 mm, solid carbide, TiAlN – TECWERK

An End mill DIN 6527L Type NF-UNI 4 mm intended for universal roughing and finishing in steel and stainless steel on precision CNC milling operations.

• Solid carbide with TiAlN coating
• 45° helix for improved chip flow
• Four flutes for stable cutting
• Cylindrical shank to DIN 6535 HB
• Suitable for roughing and finishing

Delivering consistent precision and process stability

The tool is engineered to offer exceptional stability through a specialised cutting geometry that reduces vibration and run-out. With a solid carbide body and a long design, the cutter maintains form under cutting forces, which translates into repeatable part tolerances and reduced scrap rates. This stability benefits shops pursuing tighter dimensional control and predictable tool life in production runs.

Coating technology that extends tool life under heat

The multilayer TiAlN coating provides a robust barrier against abrasive wear and thermal degradation. The coating offers improved temperature stability, making the cutter suited to operations where heat build-up occurs, for example during high-speed passes or interrupted cuts. As a result, tool change intervals are extended and tool management is simplified without sacrificing surface finish quality.

Versatility across common engineering materials

Designed for universal use, the cutter is optimised for steel and stainless steel, showing very good performance on these materials while remaining conditionally suitable for non-ferrous metals, cast iron and certain special alloys. The combination of 4 flutes and a 45° helix balances material removal rate with surface integrity, enabling both schrupp-style roughing and fine finishing in a single tool when set-up and feeds are matched.

Workshop fit and integration for straightforward use

With a 4 mm diameter, 4 mm cutting length, overall length of 57 mm and a 6 mm cylindrical shank to DIN 6535 HB, the cutter integrates easily into standard toolholders and collet systems. The right-hand cutting orientation and the inclusion of a chip-splitter and unequal division on the flutes improve chip control and help avoid clogging in deeper pockets, reducing the risk of rework and downtime in daily machining operations.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill is very well suited for steel and stainless steel, and conditionally suitable for non-ferrous metals, certain special alloys and cast iron as indicated in the product specifications.

What are the key dimensions to check for toolholder compatibility?
Check the 4 mm diameter, 6 mm cylindrical shank to DIN 6535 HB and overall length 57 mm to ensure compatibility with the chosen collet or holder.

How does the TiAlN coating benefit machining?
The TiAlN coating increases wear resistance and thermal stability, improving performance during higher cutting temperatures and extending tool life.

Can this cutter be used for both roughing and finishing?
Yes, the cutter’s geometry and four-flute design make it suitable for both roughing and finishing operations when cutting parameters are set appropriately.

Is the cutting direction right- or left-handed?
The cutter is right-hand cutting, suitable for conventional milling set-ups.
