NR-UNI roughing end mill Ø16 mm — VHM, TiAlN, 4-flute, long (TECWERK)

A NR-UNI roughing end mill Ø16 mm designed for robust material removal in steel, non-ferrous metals and castings, offering long reach and stable roughing performance for workshop and production environments

• VHM solid carbide, universal fine grain
• TiAlN coating for high-temperature resistance
• Special roughing profile for low-vibration machining
• 45° helix and neck relief for deep-pocket access

Stable, high-rate material removal with reduced chatter

The combination of VHM (solid carbide, universal fine grain) and a TiAlN coating delivers thermal stability and wear resistance during heavy roughing passes. The cutter’s special roughing profile and positive rake angle actively split chips and reduce cutting forces, which results in quieter, more stable removal rates and fewer rejected parts. This geometry is particularly effective when working with steel and non-ferrous metals, where the design maintains cutting integrity over longer cycles and supports consistent surface quality during pre-finishing operations.

Secure clamping and geometry built for precision and reach

A cylindrical shank manufactured to DIN 6535 HB with a h6 tolerance ensures concentricity and repeatable clamping in standard toolholders, improving balance and reducing runout-related wear. The long version (overall length 92 mm) and a neck relief (freed clearance approx. 15.5 mm) permit access into deep pockets and stepped features while keeping the working portion free from interference. The 45° helix provides a compromise between axial engagement and chip evacuation, making the cutter versatile for interrupted cuts and tougher engagement angles.

Efficiency through chip control and adaptable application range

With 4 flutes and an effective cutting length of 40 mm, the tool supports higher feed per tooth strategies while maintaining chip breaking thanks to the roughing profile. This leads to fewer tool changes and shorter cycle times in batch production. Material suitability is broad: very good for steel, non-ferrous metals and cast iron, conditional for stainless steel and certain special alloys. For workshops seeking to streamline tool inventories, the cutter’s universal carbide grade and coating mean a single reference can cover many roughing tasks with reliable life and performance.

Application guidance and process reliability

The right-hand cutting direction and long flute form make the cutter particularly suited to conventional milling set-ups and CNC applications requiring stable toolpaths. The neck relief and protective chamfer combine to reduce the risk of tool fracture when entering features. Although optimised for roughing, the cutter’s geometry allows measured material exits with good chip control, reducing load peaks on both machine and spindle and supporting repeatable production output.

FAQ

What materials is this roughing cutter suitable for?
The NR-UNI roughing end mill is optimised for steel, non-ferrous metals and cast iron (very good suitability); stainless steel and certain special alloys are listed as conditionally suitable for the TECWERK roughing cutter SKU 2000866123NW.

Which shank and tolerance does the tool use for mounting?
The tool features a cylindrical shank to DIN 6535 HB with h6 tolerance to ensure concentric clamping and repeatable runout performance in standard holders.

What advantages does the TiAlN coating provide?
The TiAlN coating increases oxidation resistance and thermal stability at elevated cutting temperatures, extending tool life and supporting more sustained roughing cycles with the TECWERK VHM cutter.

How does the roughing profile affect machining behaviour?
The special roughing profile improves chip fragmentation and reduces cutting forces, enabling low-vibration machining and more consistent material removal during heavy cuts.

Is the cutter suitable for deep-pocket milling?
Yes — the long version, neck relief and an effective cutting length of 40 mm make the cutter appropriate for deeper pockets while maintaining chip evacuation and tool stability.
