Keyway cutter DIN 327D Type N, Ø18 mm – HSS‑Co8, TiCN (TECWERK)

A short, two‑flute keyway cutter designed for precise slotting and form‑accurate keyways in steels and stainless materials

• HSS‑Co8 with TiCN coating
• Two‑flute for precise keyways
• Weldon shank Ø16 mm
• Suited for steel up to ~1000 N/mm²

Precision for tight, form‑accurate fits

The keyway cutter DIN 327D Type N is engineered for machining narrow, form‑accurate slots and deeper keyways where repeatability matters. The two‑flute geometry delivers a balanced cut with reduced radial runout, which helps maintain tight dimensional tolerances in serial production. The central cutting feature enables entry at position without pilot holes in many cases, reducing setup time and ensuring consistent part-to-part accuracy when producing passfedernuten or fitted grooves.

Wear resistance and consistent surface finish

Constructed from HSS‑Co8 and enhanced with a TiCN coating, this short cutter offers improved abrasion resistance and longer intervals between regrinds compared with uncoated high‑speed steel. The coating supports elevated cutting performance when machining steel up to ~1000 N/mm², and results in a cleaner surface on materials such as stainless steel (INOX) and cast iron, both of which are listed as very well suited. For operations that require fewer tool changes and predictable tool life, this combination of substrate and coating reduces downtime and process variation.

Secure clamping and rigid machining setup

The Weldon shank with drive flats and a shank diameter of Ø16 mm provides positive torque transmission and simple, reliable fixturing in compatible tool holders. The short design improves stiffness in constrained workspaces, lowering deflection during entry and while cutting deep slots. Right‑hand cutting and the cylinder shank with driving surface are intended for conventional spindle set‑ups and make the cutter straightforward to integrate into standard milling centres and tool posts without special adaptors.

Broad application range with predictable results

This cutter is specified for materials with low to medium tensile strength up to the stated limit, making it suitable for general engineering tasks as well as demanding assemblies that require precise fits. While non‑ferrous and special alloys are noted as conditionally suitable, the tool excels when used on narrow slots and deep keyways in ferrous components where surface quality and dimensional control are decisive. The result is fewer reworks, stable cycle times and an overall improvement in process efficiency for production and repair work.

FAQ

What is the intended use for this keyway cutter?
This short two‑flute cutter is intended for machining narrow, form‑accurate slots and deep keyways in ferrous components, following the DIN 327D Type N specification.

Which materials does the cutter perform best on?
The TECWERK cutter performs very well on steel up to approximately 1000 N/mm², stainless steel (INOX) and cast iron; non‑ferrous and special alloys are conditionally suitable.

What are the shank and mounting details?
The tool features a Weldon shank with drive flats and a shank diameter of 16 mm for secure clamping and positive torque transmission.

Is the cutter coated and what are the benefits?
Yes, the cutter is made from HSS‑Co8 and coated with TiCN to increase wear resistance, extend service life and improve surface finish in production environments.

Can this cutter be used without pilot holes?
Thanks to the central cutting design, the cutter can often enter material without a pilot hole for many slotting operations, depending on the workpiece setup and material.
