4mm Milling Cutter DIN 6527K Type N TiAlN Coated Solid Carbide 2-Flute Short, 45° Chamfer, Cylindrical Shank DIN 6535 HB - TECWERK

The combination of solid-carbide construction, TiAlN surface treatment and a two-flute, centre-cut geometry ensures reliable performance for both roughing and finishing in a wide range of materials; order the slot drill directly via Metav Werkzeuge or ask our consultants if needed

TECWERK slot drill DIN 6527K – Ø4 mm, VHM, TiAlN, 2-flute (short)

A compact, centre-cut slot drill designed for short, vibration-reduced machining in steels, cast irons and non-ferrous alloys

• Solid-carbide (VHM) construction for rigidity and life
• TiAlN coating for heat and wear resistance
• Two-flute centre-cut geometry for effective chip evacuation
• Cylindrical shank to DIN 6535 HB, Ø6 mm

High-performance cutting for mixed production needs

The short, two-flute slot drill built to DIN 6527 combines a solid, fine-grain VHM body with a TiAlN coating to deliver stable cutting in both roughing and finishing passes. The centre-cut design allows plunge entry while the compact Ø4 mm diameter and the dynamic helix provide controlled chip flow. These characteristics translate into reliable machining of common workshop materials with reduced tool chatter and longer service intervals, supporting an efficient production flow.

Geometry engineered for low vibration and versatile use

A newly developed cutting geometry with 45° chamfer, neck relief and a short overall length focuses on rigidity and vibration damping. The two cutting edges ensure balanced cutting forces and improved surface quality on interrupted cuts, while the 3.8 mm relief behind the cutting zone reduces contact and friction. Together, these features make the tool particularly suited to confined setups and small-spindle machines where stability and finish are priorities.

Coating and material pairing explained

The TiAlN surface layer increases resistance to heat and abrasive wear, making the cutter especially effective in high-temperature conditions and when machining abrasive alloys. Paired with the VHM substrate, the coating supports extended life in applications such as steel, stainless steel (INOX), cast irons and many non-ferrous metals. For customers less familiar with coatings: TiAlN forms a protective oxide layer at elevated temperatures, which helps maintain edge integrity during sustained contact with the workpiece.

Practical handling, compatibility and workshop benefits

A cylindrical shank to DIN 6535 HB with Ø6 mm and h6 tolerance ensures secure clamping in common tool holders, while the short design eases tool changeovers and reduces overhang. The cutter’s centre-cut capability enables slotting and plunge operations without pre-drilling, simplifying process chains. The combination of solid-carbide rigidity and optimised geometry supports both single-part prototyping and small‑batch production, helping to reduce setup times and improve first-pass yields.

FAQ

Is this cutter suitable for plunge cutting and slotting?
The TECWERK slot drill DIN 6527K features a centre-cut design that permits plunge cutting and direct slotting without prior drilling, making it suitable for both operations.

Which shank size is required for this tool?
The tool has a cylindrical shank to DIN 6535 HB with a diameter of 6 mm and tolerance h6, suitable for standard collets and tool holders that accept Ø6 mm shanks.

For which materials is the cutter recommended?
The cutter is very well suited to steel, cast iron, Cr–Ni steels (stainless), non‑ferrous metals and aluminium with silicon, and it also performs well on abrasive and special alloy materials thanks to the TiAlN coating.

How does the TiAlN coating benefit tool life?
The TiAlN coating increases thermal and abrasive resistance; in combination with the VHM substrate, it helps maintain edge stability during high-temperature cutting and prolonged cycles
