Bohrnutenfräser DIN 327D Typ N, 12 mm – short HSS-Co8 TiCN, TECWERK

A short two-flute keyway cutter (DIN 327 D, Type N) designed for precision slotting and keyseat milling in confined and form-accurate fits

• High-cobalt HSS-Co8 substrate
• TiCN coating for improved wear resistance
• Weldon shank with driving flat
• Centre-cutting for plunge operations

Precise slotting where space and tolerance matter

The short two-flute design provides controlled chip evacuation and stable cutting forces when machining narrow keyways and deep profiles. Made from HSS-Co8, the tool combines hardness with toughness to resist chipping during interrupted cuts. The centre-cutting geometry enables plunge milling as well as conventional slotting, allowing accurate seat creation without pre-drilling in many cases. For workshops and production lines seeking consistent fits, this design reduces rework and improves assembly reliability.

Durable surface treatment for longer service life

A TiCN coating (titanium carbonitride) offers a harder, more temperature-resistant surface than uncoated high-speed steels, slowing flank wear and maintaining edge integrity at elevated cutting temperatures. The coating, in combination with the high-cobalt steel, increases tool life under medium-duty conditions and supports higher cutting parameters where appropriate. This balance of substrate and coating helps to lower downtime and tooling cost per part in repetitive machining tasks.

Secure clamping and compatibility with common setups

The Weldon shank with a driving flat ensures positive torque transmission in standard holders and collet chucks, minimising slippage under radial loads. The nominal shank diameter is 12 mm with a free cutting length of 11.5 mm, making the cutter compatible with compact toolholders and tight setups. The short form factor is especially useful for machines with limited reach or when machining deep, narrow pockets where rigidity is critical for dimensional accuracy.

Broad material suitability for general engineering tasks

This cutter is specified for materials up to approximately 1000 N/mm² tensile strength. It is classified as very well suited to steel, stainless steel (INOX) and cast iron, while performance in non-ferrous metals and special alloys is conditionally suitable. That combination makes the tool versatile across maintenance, toolroom and small-batch production contexts where mixed materials are encountered. When machining harder or exotic alloys, reduced speeds and adjusted feeds are recommended to preserve tool life.

FAQ

What applications is this keyway cutter designed for? This short keyway cutter is intended for milling narrow keyways and deep keyseat profiles, providing precise fits and form-accurate slots in confined spaces.

Can the tool plunge directly without a pilot hole? Yes, the centre-cutting geometry allows plunge operations; the HSS-Co8 substrate and cutter design support controlled plunging for many slotting tasks.

Which materials is the cutter best suited to machine? The cutter is very well suited to steel, stainless steel (INOX) and cast iron; performance in non-ferrous metals and special alloys is conditional and may require adapted cutting parameters.

What holding system is recommended for secure clamping? The Weldon shank with driving flat is optimised for standard Weldon-style holders and collet chucks to prevent slippage during machining.

Is this cutter compatible with machines used for compact workshop setups? Yes, the short form factor and 12 mm shank diameter make it suitable for machines and toolholders with limited overhang where rigidity is essential.
