TECWERK solid‑carbide end mill DIN 6527 L – Ø 20 mm, TiAlN coated

The TECWERK solid‑carbide end mill DIN 6527 L is a long‑reach, four‑flute tool engineered for high‑performance roughing and finishing across steels, cast irons and non‑ferrous alloys

• Solid carbide, fine‑grain construction
• TiAlN coating for heat and wear resistance
• Centre cutting, 4 flutes for versatile milling
• Long‑reach design for deep pocketing

Robust construction for demanding production

Made from solid carbide with a TiAlN surface layer, the tool combines high hardness and thermal stability to extend tool life under elevated cutting temperatures. The HPC‑oriented geometry and fine‑grain carbide substrate enable reliable material removal rates while maintaining edge stability. With a Ø 20 mm diameter and an effective length 50 mm, the design supports aggressive axial engagement without rapid wear, making it a dependable choice where tool longevity and consistent surface quality are required.

Precision features that reduce vibration and improve accuracy

The tool is specified to DIN 6527 L and fitted with a h6 shank to ensure concentric clamping and low run‑out when mounted in suitable toolholders. An unequal helix and dedicated neck relief promote chip evacuation and break up harmonic vibrations, which helps to maintain dimensional accuracy in long‑reach operations. The combination of a centre cutting geometry and a 45° protection chamfer (0.3 mm) supports plunge starts and protects the cutting edges in interrupted cuts, delivering stable performance in both roughing and finishing passes.

Wide material compatibility and practical application guidance

Designed as a universal solution, the cutter is very well suited for steel, cast iron, stainless steel, non‑ferrous metals, special alloys and abrasive workpieces, including aluminium with silicon content. Its four‑flute layout balances chip space and flute strength, allowing efficient finishing while retaining high material removal capability. For best results in high‑speed or high‑performance cutting, pair the tool with rigid fixturing and appropriate coolant or air blast to aid chip evacuation and maintain the TiAlN film performance.

FAQ

Which materials can be machined with this end mill?
The TECWERK solid‑carbide end mill DIN 6527 L Ø 20 mm (SKU 2000866529NW) is very well suited for steel, cast iron, stainless steel, non‑ferrous metals, special alloys, aluminium with silicon content and abrasive materials.

Is the tool suitable for both roughing and finishing operations?
Yes, the tool’s HPC geometry and four‑flute design allow effective roughing while the fine‑grain carbide and TiAlN coating support high‑quality finishing passes.

What advantages does the TiAlN coating provide?
The TiAlN coating increases oxidation resistance at high temperatures, reduces friction and extends tool life under elevated cutting speeds compared with uncoated carbide.

What does centre cutting mean and why is it important?
Centre cutting indicates the tool can plunge axially into the workpiece; this enables direct entry into pockets and makes the cutter suitable for operations where vertical starts are required.

How does the tool minimise vibration in long‑reach milling?
Features such as the unequal helix, neck relief and solid‑carbide stiffness reduce harmonic vibrations and improve chip evacuation, resulting in more stable long‑reach machining.
