TECWERK Solid Carbide End Mill D20 mm, TiAlN, 5‑flute, Extra‑long

The TECWERK Solid Carbide End Mill D20 mm is an extra‑long, TiAlN‑coated cutter engineered for vibration‑reduced roughing and finishing across steels and non‑ferrous alloys

• Solid carbide VHM fine-grain
• TiAlN coating for heat resistance
• 75 mm effective length, extra-long reach
• 5-flute centre-cut for plunge milling

Faster machining in deep pockets and long reach applications

With an extended profile and deliberate cutting reach, the cutter reduces repeated tool changes in deep cavities and complex components. The 75 mm effective cutting length together with the 130 mm overall length ensures longer accessibility, while the 3×D cutting length gives predictable engagement for stable metal removal. Longer reach shortens cycle times on multi‑stage parts and simplifies fixture strategies, delivering measurable efficiency gains on batch runs and single‑piece flow.

Coating and geometry that extend tool life and process reliability

A fine‑grain VHM substrate combined with TiAlN surface treatment supports elevated cutting speeds and higher thermal resistance, directly improving tool life under mixed machining loads. The optimised flute geometry with unequal pitch and a 45° protective chamfer suppresses harmonic excitation for low‑vibration machining. Because the cutter is centre‑cut, it also permits safe plunge operations, enabling a single tool to perform both entry cuts and conventional milling passes.

Consistent clamping and predictable surface quality

Accurate holding is provided by the DIN 6535 HB cylindrical shank with h6 tolerance, promoting concentric clamping in standard collets and predictable run‑out. The 20 mm shank diameter paired with the 5‑flute arrangement balances chip load and surface contact for improved finishes. Right‑hand cutting geometry suits standard machining cycles on rigid setups, making the tool compatible with common machine tool interfaces and collet systems.

Universal material range for consolidated tool sets

The tool’s geometry and coating make it a universal solution for a wide material spectrum: steels, various cast irons, Cr‑Ni alloys, non‑ferrous metals and aluminium alloys containing silicon. Rated as very well suited for INOX and abrasive applications, the cutter performs both roughing and finishing tasks, which helps to reduce inventory complexity and to harmonise machining strategies across mixed production runs.

FAQ

Is this cutter suitable for plunge cutting and pocketing?
Yes. The centre‑cut design of the TECWERK solid carbide end mill allows plunge cutting and pocketing operations in addition to conventional milling passes.

Which materials can be machined reliably with this tool?
The cutter is designed as a universal solution and is very well suited for steel, INOX (stainless steel), castings, non‑ferrous metals and aluminium alloys containing silicon, as stated in the technical features.

How does the TiAlN coating influence cutting performance?
TiAlN increases thermal stability at the cutting edge, reducing wear under higher temperatures and permitting increased cutting speeds while maintaining surface quality and tool life.

What clamping accuracy can be expected from the shank?
The DIN 6535 HB cylindrical shank with h6 tolerance provides consistent concentricity in standard collets, delivering predictable run‑out and stable surface finish.

Will the tool reduce vibration during roughing passes?
Yes. The optimised flute geometry with unequal pitch and a 45° protective chamfer is engineered to suppress chatter and support low‑vibration machining during heavy material removal.
