TECWERK Solid Carbide End Mill D20 mm — TiAlN, 35–38° helix

A TECWERK D20 mm solid carbide end mill designed for vibration‑reduced roughing and finishing across steels, cast iron and non‑ferrous alloys.

• Solid carbide VHM construction
• TiAlN coating for heat resistance
• Extra‑long shank for deep reach
• 35–38° helix for improved chip evacuation

High‑performance materials for longer tool life

The tool combines VHM (solid carbide) substrate and a TiAlN coating to deliver high wear resistance and thermal stability under demanding conditions. The harder carbide core provides rigidity for stable cuts, while the TiAlN layer reduces oxidation and supports higher cutting temperatures; this results in extended service life and fewer tool changes. Practical benefits include reduced downtime and a more predictable production rhythm when machining demanding alloys.

Geometry designed to cut faster and reduce vibration

With an 8‑flute configuration, a short cutting length of 8 mm and an effective length of 70 mm, the cutter offers a balance between wear distribution and rigidity for deep pockets and stepped features. The tool features variable pitch and a dedicated neck relief that lower harmonic excitation and reduce chatter. A cylindrical shank to DIN 6535 HB with h6 tolerance ensures precise clamping and concentricity in milling holders, while the 0.3 mm protective chamfer preserves the first cutting edge during entry.

Wide material suitability with clear process benefits

This multi‑flute design, together with a 35–38° helix, supports efficient chip evacuation and stable cutting in a broad range of materials: steels, cast iron, temper castings, Cr‑Ni steels (INOX), non‑ferrous metals and abrasive alloys, including aluminium with silicon content. The cutter is optimised for both roughing and finishing, so each pass can be tuned for either high material removal rates or improved surface quality, reducing the number of tool variants required on the shop floor.

Suitable for production‑grade machining and easy integration

The extra‑long shank and right‑hand cutting geometry make this cutter suitable for CNC operations where reach and repeatability matter. The robust design minimises tool deflection during heavy cuts and the TiAlN finish supports dry or reduced‑lubrication strategies in many setups. Proven measures such as shank tolerance and neck relief simplify toolholder selection and contribute to consistent part tolerances across batch runs.

FAQ

What materials is this cutter best suited for?
The TECWERK solid carbide end mill (SKU 2000866999NW) is very well suited for steel, cast iron, INOX, non‑ferrous metals and special alloys, including aluminium with silicon content.

How does the TiAlN coating help in production?
The TiAlN coating increases thermal resistance and reduces oxidation, so the tool sustains higher cutting temperatures and delivers longer life under continuous production loads.

What does the 35–38° helix angle achieve?
The relatively steep helix promotes smoother chip flow and reduces cutting forces per tooth, supporting higher feed rates and improved surface finish in both roughing and finishing passes.

Is the shank compatible with standard toolholders?
Yes; the cutter has a cylindrical shank to DIN 6535 HB with h6 tolerance, which ensures accurate clamping and concentricity in standard toolholders and collets.

Why choose an 8‑flute geometry for this diameter?
An 8‑flute design increases cutting edges per revolution for higher material removal rates and improved surface finish in semi‑finishing and finishing applications, while the variable pitch counters vibration.
