Bohrnutenfräser DIN 6527L Type N — 6 mm, TiAlN-coated, VHM — TECWERK

The Bohrnutenfräser DIN 6527L Type N is a long two-flute solid carbide slot cutter designed for productive slotting and plunge operations across a wide range of engineering materials.

• Solid carbide, fine-grain for long tool life
• TiAlN coating for heat and wear resistance
• Centre-cutting two-flute design
• Neck relief for vibration-free machining

Optimised cutting performance for shorter cycle times

The combination of solid carbide (VHM) base material and a TiAlN coating gives the cutter superior thermal stability and wear resistance, enabling higher cutting speeds and extended tool life. The tool’s dynamic helix and fine-grain substrate are designed to maintain chip evacuation and reduce build-up during continuous production, which improves throughput and reduces downtime for tool changes. As a result, process planners can expect a reliable reduction in machining time when replacing older geometries with this modern cutter.

Accurate slot geometry and improved surface finish

A centre-cutting, two-flute geometry provides clean entry and precise slotting without the need for pre-drilling, while the 45° protective chamfer (0.12 mm) helps preserve the cutting edge during engagement. The intentionally ground neck relief and tailored flute design minimise chatter and vibration, producing repeatable slot widths and consistent surface quality. These features translate directly into less rework and fewer scrap parts for demanding production runs.

Broad material compatibility reduces tool inventory

This cutter is developed as a universal solution: the new geometry and coating make it suitable for machining steel, cast iron, stainless steels (INOX), non-ferrous metals, aluminium with silicon, special alloys, and even abrasive materials. It is capable of both roughing and finishing, meaning one tool can cover multiple machining steps and reduce the number of items required in a tool crib. For workshops aiming to simplify logistics without compromising capability, the tool supports a wide spectrum of components and production tasks.

Practical integration and workshop readiness

The tool is supplied with a cylindrical shank to DIN 6535 HB, shank Ø 6 mm and shank tolerance h6, making it compatible with standard collets and holders. The effective relief diameter of 5.8 mm and a 20 mm cutting length ensure access to deeper slots while maintaining stiffness. The cutter is right-hand cutting with centre cutting capability, allowing plunge operations where needed. These mechanical details simplify tooling decisions and support predictable setup times on milling machines and machining centres.

FAQ

What materials can this cutter machine effectively?
The TECWERK Bohrnutenfräser is designed for a broad range of materials including steel, stainless steel (INOX), cast iron, non-ferrous metals, aluminium with silicon, and various special alloys, making it suitable for both roughing and finishing applications.

Can the cutter be used for plunge cutting?
Yes, the tool is centre-cutting, which allows plunge operations in addition to conventional slot milling, and the TiAlN coating helps preserve cutting edges under intermittent engagement.

Which shank holders are compatible with this tool?
With a cylindrical shank to DIN 6535 HB and h6 tolerance, the cutter fits standard collets and holders designed for a 6 mm shank diameter.

How does the neck relief improve machining?
The neck relief reduces tool–workpiece contact behind the cutting edges, lowering vibration and improving surface finish; this is particularly beneficial during deep slotting and long overhangs.

Is this cutter suitable for high-speed machining?
The TiAlN coating and fine-grain carbide substrate are engineered for thermal stability and wear resistance, supporting elevated cutting speeds in many common materials.
