TECWERK solid carbide end mill D20 mm, TiAlN, 8 flutes (extra long)

The TECWERK solid carbide end mill D20 mm is an extra-long, TiAlN-coated milling cutter designed for vibration-reduced roughing and finishing across a wide range of steels, cast irons and non‑ferrous alloys

• TiAlN coating for high thermal stability
• Solid carbide, fine-grain construction
• Extra-long design with 70 mm effective length
• 8-flute geometry for vibration-reduced cutting

Consistent high-performance at elevated temperatures

The combination of solid carbide (VHM) substrate and TiAlN coating delivers sustained cutting performance where heat and abrasion are challenges. The coating improves oxidation resistance and maintains edge hardness during demanding cycle times, which translates into longer tool life and fewer interruptions for tool changes. With an optimised helix geometry, the cutter supports stable chip flow while preserving surface finish in both roughing and finishing passes.

Accurate clamping and reduced vibration for repeatable results

Built with a 20 mm cylindrical shank to DIN 6535 HB and h6 shank tolerance, the tool provides precise concentricity when used with standard tool holders. The unequal pitch and 8 flutes reduce harmonic resonance for vibration‑reduced machining, while the neck relief and 45° protection chamfer protect the cutting edges during deep or extended-reach operations. These design choices support repeatable tolerances in batch production and minimise rework.

Broad material compatibility to simplify tooling strategies

The cutter’s geometry and coating make it suitable for a wide material spectrum: steels, cast iron, Cr–Ni steels (INOX), non‑ferrous metals, aluminium with silicon content and abrasive materials. That universality reduces the need for frequent tool changes and streamlines processes across turning, milling and slotting operations. The tool therefore contributes to lower overall process costs and higher machine utilisation in mixed‑material shops.

Dimensions and features that integrate into production workflows

Key form factors include a 70 mm effective length, 8 mm cutting length, overall length 126 mm, and a protective chamfer of 0.3 mm with a neck relief of 19.5 mm. The cutter is right‑hand cutting and configured as a multi‑cutter type N for efficient material removal. These measurable specifications allow straightforward integration into existing fixtures and CAM tool libraries, supporting quick set‑up and predictable cycle times for both single‑piece flow and batch production.

FAQ

Is this cutter suitable for stainless steel (INOX)?
Yes. The TECWERK solid carbide end mill with TiAlN coating is rated very well suited for INOX and other Cr–Ni steels, offering good wear resistance during stainless‑steel machining.

Can the tool be used for both roughing and finishing operations?
Yes. The combination of 8 flutes, fine‑grain carbide and optimised geometry makes the cutter suitable for both roughing and finishing, providing efficient material removal and acceptable surface quality.

What advantages does the TiAlN coating provide?
TiAlN increases thermal stability and surface hardness at elevated temperatures, extending tool life and reducing the frequency of reconditioning compared with uncoated carbide cutters.

Does the shank fit standard tool holders?
Yes. The 20 mm cylindrical shank is made to DIN 6535 HB with h6 tolerance, ensuring high concentricity and compatibility with standard collets and holders.

What applications benefit most from the extra-long effective length?
The 70 mm effective length is advantageous for deep pocketing, machining cavities and parts requiring extended reach without compromising rigidity when used in appropriate holders.
