Slot drill DIN 6527K Type N — 4 mm, solid carbide, TiAlN (TECWERK)

The Slot drill DIN 6527K Type N (Ø 4 mm) is a short, two-flute centre-cutting solid carbide cutter designed for low-vibration slotting, roughing and finishing across steels, cast irons and non‑ferrous alloys

• VHM solid carbide with fine grain
• TiAlN coating for extended tool life
• Short two-flute design, centre-cutting
• Cylindrical shank HB, h6 tolerance

High productivity across mixed materials

The short solid carbide cutter combines a universal fine-grain carbide grade with a robust cutting geometry to deliver consistent results in a wide range of substrates. The tool is specified for steel, grey and tempered cast irons, Cr‑Ni steels, non‑ferrous metals and aluminium alloys with silicon content, and it is suitable for more abrasive workpieces. This versatility reduces tool changes and streamlines production when diverse components are processed on the same machine.

Geometry engineered to reduce chatter and improve surface finish

A variable helix (dynamic pitch) together with a dedicated neck relief and low‑vibration geometry minimises harmonic excitation during slotting. The short two‑flute, centre‑cutting design enables reliable entry and stable cutting forces for both roughing and finishing passes. As a result, cycle times can be shortened while maintaining better dimensional control and a superior surface quality on machined slots.

Coating and grade for longer tool life under demanding conditions

The TiAlN coating forms a protective layer that increases temperature resistance and reduces flank wear in high‑stress applications. When combined with the fine‑grain carbide substrate, the coating improves performance in intermittent cuts and on abrasive alloys. This means fewer tool changes and lower tooling costs over long production runs, especially when machining harder stainless steels or silicon‑bearing aluminium alloys.

Secure clamping and precise shank dimensions for repeatable results

The cutter features a 6 mm cylindrical shank manufactured to h6 tolerance and conforms to DIN 6535 HB for reliable clamping. A protective chamfer of 0.07 mm and a relief length of 3.8 mm support vibration‑reduced engagement and safe axial entry. Right‑hand cutting and centre‑cutting capability ensure predictable chip formation and make the tool suitable for automated setups where repeatability is essential.

FAQ

Is this cutter suitable for stainless and hardened steels?
The TECWERK slot drill (slotting cutter, SKU 2000866153NW) is specified as very well suited for Cr‑Ni steels and general steel applications; for hardened or heat‑treated components, cutting parameters should be adapted accordingly.

Can the tool perform plunge cuts?
Yes, the cutter is centre‑cutting, which allows axial entry and controlled plunge operations when set up with appropriate feeds and speeds.

What advantages does the TiAlN coating offer?
TiAlN increases thermal resistance and wear protection; on the TECWERK slot drill this results in extended tool life and improved performance on abrasive and high‑temperature cuts.

Is the shank compatible with standard toolholders?
The cylindrical HB shank conforms to DIN 6535 HB and is produced to h6 tolerance, ensuring secure clamping in standard collets and chucks designed for 6 mm shanks.

For which operations is this cutter recommended?
The cutter is recommended for slotting, roughing and finishing operations in a variety of materials, offering a balance between productivity and surface quality during continuous or intermittent machining.
