TECWERK solid carbide roughing end mill NR‑UNI — 14 mm, TiAlN, 35 mm cutting length

The TECWERK solid carbide roughing end mill NR‑UNI (14 mm, 35 mm effective length) is a long‑reach, 4‑flute cutter optimised for high‑capacity roughing of steel, cast materials and non‑ferrous metals in CNC machining environments.

• Solid carbide fine‑grain body
• TiAlN thermal barrier coating
• 4‑flute roughing geometry
• 45° helix, 45° chamfer
• DIN 6535 HB shank, h6 tolerance

Faster roughing with stable chip control

The combination of a solid carbide (fine‑grain) substrate and a TiAlN coating creates a tool that withstands elevated temperatures and abrasive conditions during heavy cuts. The cutter’s roughing profile reduces cutting forces by breaking chips into smaller segments, which lowers the risk of chatter and enables higher feed rates in interrupted or deep cuts. With a 4‑flute geometry and a 45° helix, the design balances axial engagement and radial stability, making the cutter particularly suited to aggressive material removal without compromising runout or surface integrity.

Reliable performance across common workshop materials

Designed for universal use, the tool delivers very good suitability for steel, non‑ferrous metals and castings, while offering conditional performance on certain stainless and special alloys. The positive rake angle contributes to easier chip formation and reduced cutting forces, which benefits both spindle load and tool life. The tool’s neck relief and specified free relief of 13.6 mm aid vibration dampening in long‑reach operations, improving dimensional consistency on roughing passes and preparing the workpiece efficiently for subsequent finishing operations.

Accurate mounting, predictable tool life and process security

A cylindrical shank per DIN 6535 HB with h6 tolerance ensures consistent clamping and concentricity in standard holders, simplifying tool change‑over and reducing setup time. The cutter’s right‑hand cutting direction and the long overall length facilitate access to deep cavities and stepped features on milling machines. Together with the TiAlN barrier and fine‑grain carbide, these characteristics support extended tool life and predictable performance in production runs, helping maintain flow and reduce unplanned downtime.

FAQ

What materials is this roughing end mill best suited for?
The TECWERK solid carbide roughing end mill is very well suited for steel, non‑ferrous metals and castings, with conditional suitability for certain stainless steels and special alloys.

Which shank standard and tolerance apply to this tool?
The cutter features a cylindrical shank to DIN 6535 HB with an h6 tolerance, ensuring precise clamping and consistent concentricity in standard holders.

How does the TiAlN coating improve performance?
The TiAlN coating acts as a thermal barrier and increases oxidation resistance, reducing flank wear under elevated temperatures and extending the service life of the tool during heavy roughing.

What advantages does the roughing geometry provide in production?
The special roughing profile breaks chips into smaller segments to reduce cutting forces and chatter, enabling higher feed rates and more stable heavy material removal.

What are the helix and cutting direction of the tool?
The tool has a 45° helix angle and is right‑hand cutting, optimised for effective chip evacuation and balanced axial/radial cutting engagement.
