TECWERK End Mill DIN 6527L, 20 mm — VHM, TiAlN, 8‑flute, long

The TECWERK End Mill DIN 6527L is a long solid‑carbide cutter with TiAlN coating and eight flutes, engineered for vibration‑reduced roughing and finishing across steels, cast materials and non‑ferrous alloys

• Solid carbide, TiAlN coating for long tool life
• 8 flutes for high material removal rates
• 35–38° helix for smooth chip evacuation
• Long shank, vibration‑reduced roughing and finishing

Faster, more reliable cutting across mixed materials

The long solid‑carbide tool with TiAlN surface treatment combines thermal resistance with wear protection to maintain cutting geometry under higher temperatures. This results in improved tool life and consistent edge retention when machining steels, stainless alloys and aluminium alloys with silicon content. The 8‑flute geometry increases contact area for higher feed rates while the 35–38° helix supports controlled chip formation, so operators achieve stable material removal without compromising surface quality.

Stable grip and reduced chatter for superior surface finish

A cylindrical shank manufactured to h6 tolerance and conformity with DIN 6535 HB secures a precise connection to the tool holder, reducing run‑out and enabling repeatable accuracy. The tool’s unequal pitch and neck relief (Halsfreischliff) lower harmonic excitation, delivering vibration‑reduced machining even on long overhangs. These characteristics translate into fewer rejects, less rework and a measurable improvement in process stability for serial and single‑piece production.

One tool for roughing and finishing with predictable results

The combination of a long shank, 8‑cutter layout and optimised cutting geometry makes the cutter suitable for both aggressive stock removal and fine finishing passes. The small protective chamfer (0.3 mm) preserves the tool tip during engagement and the compact cutting length (8 mm) with an effective working length of 50 mm provides a controlled engagement depth. Process planners benefit from reduced tool changes and consistent part quality, which supports higher throughput and lower per‑part machining cost.

FAQ

What materials is this end mill suited to machine?
The TECWERK end mill is designed for a broad range of materials; it is very well suited for steel, cast iron, stainless steel, non‑ferrous metals and special alloys thanks to its solid‑carbide substrate and TiAlN coating.

How does the TiAlN coating benefit machining?
TiAlN on the TECWERK cutter increases thermal resistance and surface hardness, which helps maintain cutting performance at higher temperatures and extends tool life under demanding conditions.

What does the 35–38° helix angle mean in practice?
A 35–38° helix supports smoother chip flow and reduced cutting forces; the geometry on this tool promotes controlled chip evacuation and stable cutting when high feeds are required.

Can this tool be used for both roughing and finishing operations?
Yes, the long 8‑flute design and optimised geometry allow the tool to perform both roughing and finishing, providing versatility in a single cutter.

What is the significance of the shank tolerance h6 and DIN 6535 HB?
A shank tolerance of h6 and a DIN 6535 HB cylindrical shank ensure precise clamping and low run‑out, which improves repeatability and surface quality in production.
