TECWERK Solid Carbide End Mill Ø20 mm, TiAlN, 5 flutes, Extra‑long

The TECWERK Solid Carbide End Mill Ø20 mm is an extra‑long, 5‑flute milling cutter engineered for vibration‑reduced roughing and finishing across steels, castings and non‑ferrous alloys.

Solid carbide, fine‑grain microstructure TiAlN coating for high heat resistance Extra‑long shank for deep and reach milling 5 flutes with centre‑cut geometry

High‑performance coating and substrate for consistent metal removal

The combination of a solid carbide substrate with a TiAlN coating delivers improved resistance to abrasive wear and thermal softening during extended cutting cycles. The fine‑grain carbide achieves a consistent edge life under mixed cutting conditions, while the titanium aluminium nitride layer enhances surface hardness and reduces built‑up edge. These characteristics translate into reproducible results when machining medium and high‑alloy steels, stainless grades and many non‑ferrous materials, enabling stable removal rates and predictable tool life in production environments.

Geometry tailored to reduce vibration and extend reach

An extra‑long design with an optimised neck relief and unequal pitch reduces the propensity for chatter in long‑reach milling operations. The tool features a centre‑cut for safe plunging and a 45° protective chamfer that shields the cutting edges during entry and exit. With a cylindrical shank to DIN 6535 HB and shank tolerance h6, the cutter provides secure clamping and concentricity when used in holders, while the unbalanced pitch improves chip evacuation and surface finish during both roughing and finishing cycles.

Universally applicable across a wide material spectrum

Thanks to the new geometry and coating combination, the cutter is suitable for machining steel, cast iron, Cr‑Ni stainless steels, non‑ferrous metals and aluminium alloys containing silicon, as well as certain abrasive materials. The multi‑flute configuration balances material removal and surface integrity: the five cutting edges permit high feed per tooth for efficient roughing while maintaining the potential for fine finishing passes where required. In practical terms, this means fewer tool changes and a smoother workflow on mixed‑material production runs.

Designed for workshop reliability and process clarity

Specifications such as a defined effective length of 75 mm, overall length of 130 mm and robust shank design ensure compatibility with common toolholding solutions and predictable tool stick‑out. The incorporated protective chamfer (0.3 mm) and neck clearance (19.5 mm) contribute to edge protection and reduce the risk of premature wear during interrupted cuts. Combined with Metav’s accessible stocking and technical advice, this cutter suits job shops and production lines seeking reproducible quality without complex process tuning.
