Slot cutter DIN 6527 K Type N, 20 mm – solid carbide, TiAlN-coated (TECWERK)

A short, centre-cut slot cutter (DIN 6527 K Type N) designed for vibration-reduced roughing and finishing across steels, castings and non-ferrous alloys

• Solid carbide VHM, fine-grain
• TiAlN coating for heat resistance
• Three cutting edges with centre cut
• Shank DIN 6535 HB, tolerance h6
• Unequal helix for low-vibration machining

Higher material removal with controlled edge stability

The short 3-flute geometry combines rigidity with a centre-cutting capability, enabling secure plunge and slot operations without sacrificing stability. Thanks to the solid carbide substrate and TiAlN wear resistance, the tool maintains cutting performance during extended cycles when machining steel, stainless steel and alloyed materials. The reduced overhang inherent to the short design increases effective stiffness, which in practical terms means higher achievable feed rates and better surface finishes during both roughing and finishing passes.

Geometry tuned to suppress chatter and improve surface quality

Unequal helix pitch and a dedicated relief profile reduce harmonic excitation during cutting, resulting in low-vibration machining even in interrupted cuts. A protective 45° chamfer and precise relief length offer reliable chip control and prevent premature chipping of the cutting edges. These geometric decisions translate directly into fewer rejects and more consistent part quality in mixed-production environments where both cast components and forged steels are processed.

Standardised shank and compact dimensions for reliable toolholding

With a shank DIN 6535 HB and h6 tolerance, the shank diameter aligns with widely used toolholders to ensure repeatable concentricity and minimal runout. The cutter’s diameter is 20 mm, the total length is 92 mm, and the short cutting length increases rigidity for demanding slotting tasks. The centre-cutting capability allows plunge cutting where appropriate, while the three-edge design balances chip evacuation with radial cutting stability.

Long-term productivity through coating and material choice

The combination of a fine-grain carbide substrate and a TiAlN top layer improves thermal stability and resistance to adhesive wear, extending tool life under elevated temperatures and high contact pressures. This makes the cutter well suited to a wide range of materials including cast irons, Cr–Ni steels, non-ferrous alloys and abrasive aluminium grades. The result is fewer tool changes, reduced downtime and a steadier process window for production runs.

FAQ

What operations can this slot cutter perform?
The TECWERK slot cutter (DIN 6527 K Type N) is designed for slotting and plunge operations, enabling both roughing and finishing passes thanks to its centre-cutting 3-flute geometry.

Which materials is the cutter best suited for?
This cutter is suitable for a broad range of materials including steel, stainless steel, cast irons, non‑ferrous alloys and abrasive aluminium grades, with the TiAlN coating improving life under thermal load.

How does the unequal helix help in production?
The unequal helix reduces harmonic excitation, which lowers the tendency to chatter and improves surface consistency during interrupted cuts and slotting.

What advantages does a short cutting length provide?
A short cutting length increases rigidity, reduces deflection and enables higher stable feeds and better surface finish compared with longer overhang cutters.

Which shank standards and tolerances apply to this tool?
The cutter features a cylindrical shank compliant with DIN 6535 HB and a tolerance of h6 for reliable concentricity in standard toolholders.
