4mm Solid Carbide End Mill TiAlN Coated 35° 4-Flute Extra Short, DIN 6527 - TECWERK

Benefit from the combination of solid carbide construction, TiAlN coating and an extra-short form for vibration‑reduced roughing and fine finishing—efficient performance and consistent surface quality. Order the part directly via Metav Werkzeuge or ask our consultants if needed.

TECWERK extra-short solid carbide end mill, Ø4 mm, TiAlN, 35° helix

The TECWERK extra-short solid carbide end mill Ø4 mm is a compact, high-performance cutter intended for high‑feed roughing, finishing and slotting in steel and cast iron applications.

• Solid carbide, fine-grain, TiAlN-coated
• 4‑flute centre-cut design for axial plunging
• Extra-short 4 mm diameter for stable cuts
• Very good for steel and cast iron up to 45 HRC

Faster, more reliable stock removal with optimised HPC geometry

The extra‑short, 4 mm diameter tool combines a proven HPC geometry with an unequal pitch to reduce harmonic vibration and increase tool life. The TiAlN coating improves thermal resistance at elevated cutting speeds and helps maintain edge integrity, which results in higher metal removal rates and extended tool life during serial machining. The cutter’s centre-cut capability and four flutes allow safe plunge operations and efficient chip evacuation, providing a balance between aggressive material removal and surface finish.

Stable cuts and consistent surface quality for demanding steels

Designed for high demands in steel machining, the tool’s fine‑grain solid carbide body and 35° helix deliver a controlled, softer cutting feel (10°), reducing chatter during interrupted cuts. The combination of a short, rigid overhang and a 0.2 mm chamfer with a 45° relief ensures predictable entry behaviour and improved edge strength. These features make the cutter especially effective when preparing components that require consistent dimensional accuracy and improved surface textures without frequent tool changes.

Versatile application range with clear material guidance

The cutter is optimised for steel and grey cast iron, with conditional suitability for stainless steel and non‑ferrous metals such as copper, brass and aluminium. Use the tool for roughing, semi‑finishing and slotting where rigidity and vibration control are crucial. The tool’s cylindrical shank to DIN 6535 HB with h6 tolerance ensures concentric clamping and minimal runout, supporting repeatable results on standard toolholders and reducing downstream rework.

FAQ

Is this cutter suitable for plunge cutting?
Yes. The TECWERK extra‑short solid carbide end mill Ø4 mm features a centre‑cut geometry that permits controlled axial plunging and safe entry into the workpiece.

Which materials are best machined with this tool?
The cutter is optimised for steel and grey cast iron, performs well up to 45 HRC, and is conditionally suitable for stainless steel and non‑ferrous metals such as aluminium, copper and brass.

What advantages does the TiAlN coating provide?
The TiAlN coating increases thermal resistance, reduces wear at elevated speeds and helps maintain edge life, supporting higher cutting speeds and longer tool life in demanding steel operations.

What clamping standard does the shank follow?
The tool has a cylindrical shank to DIN 6535 HB with h6 tolerance, ensuring concentric clamping and low runout for reproducible machining.

How does the unequal pitch help in practice?
Unequal pitch interrupts harmonic frequencies and reduces vibration, which results in smoother cutting behaviour, improved surface finish and longer tool life during serial production.
