Slot drill DIN 6527L Type N, 4 mm – solid carbide, TiAlN (TECWERK)

The Slot drill DIN 6527L Type N is a long two-flute solid carbide cutter designed for low-vibration slotting, capable of both roughing and finishing in a wide range of engineering materials.

• Solid carbide with TiAlN coating
• Two-flute, centre-cutting geometry
• 6 mm cylindrical shank, h6 tolerance
• Vibration-reducing neck relief

Greater cutting performance across mixed materials

The TiAlN coating combined with a solid carbide substrate delivers high thermal resistance and wear protection, enabling longer tool life under elevated cutting temperatures. The long version with centre-cutting capability allows plunge entry and effective slotting in steels, cast irons and non-ferrous alloys; this makes the tool suitable for continuous CNC operations where maintenance windows are limited. The combination of coating and substrate also improves edge stability when machining abrasive or Si-containing aluminium grades, so fewer tool changes are needed and cycle times become more predictable.

Stability and precision that reduce scrap rates

Designed to DIN 6527 L Type N standards, the cutter features a dynamic pitch and a neck relief to lower harmonic excitation and suppress chatter. A 45° protective chamfer (0.07 mm) and a freeshank of 3.8 mm contribute to controlled chip flow and axial stability, while the h6 shank tolerance on the 6 mm cylindrical shank ensures repeatable clamping concentricity in collets and tool holders. These attributes translate into consistent slot geometry and surface finish when alternating between roughing cuts and fine finishing passes.

Practical advantages for the workshop and production line

With two cutting edges and a geometry optimised for chip evacuation, the cutter supports efficient slotting at higher feed rates without compromising finish quality. The tool’s universality—proven performance on steel, stainless (INOX), cast iron, special alloys and non-ferrous metals—reduces the need for multiple specialised cutters, simplifying tool inventory management. For production planners, the result is a more resilient machining process: fewer interruptions, lower tooling turnover and steadier output quality, backed by a tool that is specifically configured for vibration‑reduced machining.

FAQ

Is this cutter suitable for plunge cutting into steel?
The TECWERK slot drill with centre-cutting geometry allows plunge entry and is suitable for slotting and plunge operations in steels when used with appropriate feeds and speeds.

What shank size and tolerance does the tool require?
The cutter has a 6 mm cylindrical shank with an h6 tolerance, compatible with collets and holders made for DIN 6535 HB shanks.

Which materials can be machined with this tool?
The tool is optimised for a broad range of materials including steel, stainless steel (INOX), cast iron, non-ferrous metals, aluminium alloys with silicon and certain abrasive materials.

How does the TiAlN coating benefit production?
The TiAlN coating increases heat resistance and surface hardness, improving wear life during high-temperature cutting and extending tool life in demanding applications.

Can this cutter be used for both roughing and finishing?
Yes, the geometry and two-flute design make it suitable for both roughing and finishing passes, offering a balance between material removal rate and surface quality.
