Slot drill DIN 6527L Type N Ø 8 mm — solid carbide, TiAlN-coated, long version by TECWERK

Slot drill DIN 6527L Type N Ø 8 mm is a long, centre‑cutting, three‑flute tool designed for low‑vibration slotting and both roughing and finishing across steels, castings and non‑ferrous alloys

• Solid carbide, TiAlN coating for long tool life
• Centre‑cutting three‑flute design for slotting
• 8 mm cylindrical shank to DIN 6535 HB, tolerance h6
• Unequal pitch for vibration‑reduced machining

Precision material and coating for extended tool life

The long, solid construction and solid carbide substrate combined with a TiAlN coating deliver superior wear resistance and oxidation stability at elevated temperatures. This translates into fewer tool changes and lower downtime in batch production. The coating also supports higher cutting speeds where appropriate, while the long flute form maintains chip control during deep slotting. Such characteristics improve overall process economy by extending service intervals and maintaining consistent part quality.

Geometry engineered to reduce chatter and improve surface finish

A centre‑cutting, three‑flute layout with an intentionally unequal pitch reduces harmonic vibration and stabilises the cutting process when slotting or plunging. The tool features a small 45° chamfer (protective chamfer 0.12 mm) and a neck relief that enables access into narrow features while keeping the cutting forces manageable. These design choices support both roughing and finishing operations, yielding efficient material removal rates together with improved surface integrity on steels, stainless steels, cast irons and many non‑ferrous alloys.

Secure clamping and workshop compatibility to ensure repeatability

The cylindrical shank manufactured to DIN 6535 HB with tolerance h6 ensures repeatable seating in standard holders and collets, reducing runout and improving concentricity. With a 8 mm shank diameter and a free relief length of 7.7 mm, the tool suits conventional holders while the right‑hand cutting and centre‑cutting capability make it versatile for multi‑axis and plunge‑cut operations. The combination of geometry and shank standard makes this cutter a dependable choice for industrial workshops seeking consistent results across a wide material range.

FAQ

What materials is this slot drill suitable for?
The TECWERK slot drill DIN 6527L Type N Ø 8 mm is specified for use on steel, stainless steel (INOX), cast iron, non‑ferrous metals, special alloys and aluminium with silicon content, as well as certain abrasive materials.

Is the tool suitable for plunge cutting?
Yes, the centre‑cutting geometry and three‑flute design of the slot drill allow safe plunge operations as well as conventional slotting.

How does the unequal pitch benefit machining?
Unequal pitch reduces synchronous vibration and chatter; this design feature improves stability and surface finish during slotting and finishing operations.

What shank standard and tolerance does the cutter use?
The cutter is supplied with an 8 mm cylindrical shank to DIN 6535 HB and a shank tolerance of h6, ensuring repeatable clamping and low runout.

Can this cutter be used for both roughing and finishing?
Yes, the combination of geometry and TiAlN coating makes the tool appropriate for both roughing and finishing tasks in the materials listed above.
