TECWERK Keyway cutter DIN 327D Type N — 3 mm, HSS‑Co8, TiCN, Weldon shank

A compact TECWERK keyway cutter designed for precision machining of narrow, deep keyways and form-accurate slots in steels and stainless steels, suitable for workshop milling and CNC applications.

• HSS‑Co8 base for high wear resistance
• TiCN coating for reduced friction
• Weldon shank with drive flat
• Precision for narrow, deep keyways

Exceptional cutting performance for medium‑strength materials

The cutter is manufactured from HSS‑Co8, a cobalt‑alloy high‑speed steel that offers enhanced heat resistance and wear stability compared with standard HSS. The TiCN coating further reduces friction and the tendency to form built‑up edge, which improves surface finish and prolongs tool life when machining materials up to ≈1000 N/mm². This combination is particularly effective on stainless steel and cast iron, where hardness and heat resistance are decisive for consistent cutting results.

Accurate keyways and tight tolerances with DIN 327D geometry

Designed to DIN 327D as Type N, the tool features a 2‑flute geometry and a centre cutting capability, which enables controlled plunge entry and precise slot formation. The short, rigid design supports repeatable positioning in narrow grooves and form‑accurate keyseats, reducing vibration and improving dimensional consistency. The product name appears in workshop inventories as a compact option ideal for applications demanding tight fits.

Reliable clamping and process stability in routine use

A Weldon shank with drive flat ensures secure clamping and torque transmission in standard tool holders and collet chucks, while the 6 mm shank diameter preserves stiffness in slender setups. The cutter’s right‑hand cutting action produces clean chip flow in typical milling directions and helps to minimise burr formation at the slot edges. The short configuration contributes to durability under intermittent heavy engagement, provided appropriate feeds and coolants are used.

Practical benefits for the industrial workshop

The tool is tailored for machining narrow, deep slots and keyways in production and repair environments, offering a compact alternative where access and setup space are limited. Compatibility with common milling spindles and the secure Weldon mounting reduce preparation time and increase process uptime. Combined with Metav’s stable supply chain and quality filter in Emmerich, the cutter supports a predictable tooling strategy and dependable workshop throughput.

FAQ

Is this cutter suitable for stainless steel?
Yes. The TECWERK keyway cutter is rated as very well suited for stainless steel thanks to its HSS‑Co8 substrate and TiCN coating, which together resist heat and adhesion during machining.

Can the tool produce narrow and deep keyways reliably?
Yes. The DIN 327D Type N geometry and short, rigid design enable consistent machining of narrow, deep keyways and form‑accurate slots with improved dimensional control.

Does the TiCN coating extend tool life?
The TiCN coating reduces friction and the formation of built‑up edge, helping to extend tool life and maintain surface quality during extended runs.

What shank size and clamping method are required?
The cutter has a 6 mm shank and a Weldon drive flat for secure clamping in standard tool holders and collets suited to a 6 mm diameter.

Is the cutter suitable for aluminium and other non‑ferrous metals?
The cutter is conditionally suitable for non‑ferrous metals; performance will depend on the specific alloy and chosen cutting parameters.
