End mill WN Type N, Ø 4 mm — Solid carbide, TiAlN, 35° helix (TECWERK)

The End mill WN Type N, Ø 4 mm is an extra‑short, solid carbide four‑flute cutter with TiAlN coating, designed for high‑performance roughing and finishing in steels up to 45 HRC and a range of non‑ferrous materials.

• Solid carbide, TiAlN coating for long tool life
• 4‑flute geometry with centre‑cut for plunge operations
• 35° helix for smooth chip evacuation
• Extra‑short design for vibration‑reduced cutting

Maximise material removal with predictable performance

The extra‑short solid carbide design and proven HPC geometry deliver a reliable combination of stiffness and cutting efficiency. The tool’s 35° helix promotes controlled chip flow, which reduces chatter and helps maintain consistent cutting forces during aggressive passes. With a four‑edge configuration and a centre‑cut, the cutter is suitable for helical interpolation and plunge entry, enabling faster cycle times while preserving tool life through reduced deflection.

Broad material capability with industrial confidence

Engineered for demanding shop environments, the cutter offers very good performance in steel up to 45 HRC and cast iron, with conditional suitability for stainless steel and many non‑ferrous metals such as aluminium, copper and brass. The TiAlN coating increases thermal resistance and surface hardness at elevated cutting temperatures, supporting higher cutting speeds and longer tool life without excessive wear. For users less familiar with heat‑resistant coatings, TiAlN forms a protective oxide layer in use, which reduces adhesion and improves durability.

Accurate gripping and stable cutting for precise finishes

The tool is supplied with a cylindrical shank produced to DIN 6535 HB with h6 tolerance, offering concentric clamping and reliable spindle transfer. A protective chamfer of 0.2 mm and a 45° protective edge help avoid premature corner damage when entering the workpiece or during retraction. The short, stable execution and a slight positive rake (soft cut) contribute to a smoother surface and consistent dimensional results in both roughing and finishing operations.

Practical benefits for workshop operations

Unequal pitch and four‑cutter geometry reduce harmonics and vibration, improving surface quality and tool life in interrupted cuts and slotting. The combination of centre‑cut capability and HPC profile makes the cutter versatile for pocketing, slotting and step milling with fewer tool changes. Delivered as an extra‑short option, the tool is particularly helpful where rigid setups or deep cavities demand reduced overhang to maintain accuracy and throughput across serial production.
