TECWERK Full-radius end mill D 4 mm — solid carbide, TiAlN-coated, 2 flutes

TECWERK Full-radius end mill D 4 mm is a short, centre-cutting solid carbide radius cutter engineered for precision finishing and plunge-capable slotting in steels, castings and non-ferrous alloys.

• TiAlN coating for high wear resistance
• Solid carbide, universal fine grain
• Centre-cutting for plunge capability
• Short version for increased rigidity

High-precision machining of small features and edges

The 4 mm diameter profile with an integrated R2 radius delivers repeatable edge contours and reduced deburring across batches. With an effective length 12 mm and 2 flutes, the tool provides a balance between cutting engagement and chip evacuation that supports consistent surface quality in tight geometries. The centre-cutting geometry enables plunge operations while the short design reduces overhang, resulting in improved stability and fewer rejected parts.

Coating and substrate for extended cutting cycles

The combination of solid carbide substrate and TiAlN coating raises resistance to elevated temperatures and abrasive wear, extending uninterrupted running times on demanding jobs. The coating helps maintain cutting-edge integrity, which translates into high wear resistance and longer tool life under mixed cutting conditions. Fewer tool changes mean lower machine downtime and a better cost profile per produced part.

One tool for a wide range of materials

Designed for versatile workshop use, the cutter is very well suited to steel, cast iron, stainless steel, aluminium with silicon, and many non-ferrous metals such as bronze and brass, as well as abrasive plastics. This broad material compatibility reduces tool inventories and simplifies setup planning, enabling faster changeovers and fewer sourcing decisions for mixed-production environments.

Rigidity, clamping and reliable machine integration

The cylindrical shank to DIN 6535 HB with a 6 mm shank diameter and h6 shank tolerance ensures secure clamping in standard holders and collets, while the 30° helix and right-hand cutting geometry promote smooth chip formation. The short overall length and centre-cutting capability increase rigidity for plunge and slotting tasks, lowering the risk of chatter and improving dimensional stability in serial production.

FAQ

Which materials can this cutter machine effectively? The TECWERK full-radius end mill is very well suited to steel, cast iron, stainless steels, aluminium with silicon, bronze, brass and certain abrasive plastics, offering broad versatility across workshops.

Does the tool allow plunge cutting and slotting? Yes, the centre-cutting geometry permits plunge operations and short slotting tasks while the short overall design improves rigidity for stable machining.

What benefits does the TiAlN coating provide? The TiAlN coating increases heat and wear resistance, which helps extend the cutter’s useful life and maintain consistent cutting performance in tougher operations.

What shank size and tolerance should the clamping system accept? Use a holder or collet compatible with a 6 mm shank and h6 tolerance; the DIN 6535 HB cylindrical shank ensures secure clamping for productive runs.

Can the cutter be used across serial production and prototypes? Yes — the tool’s combination of solid carbide substrate, coating and short geometry makes it suitable for both serial production and precision prototyping; SKU 2000866971NW identifies the short full-radius version.
