3mm N-Type Keyseat Cutter HSS-Co8 TiCN Coated Long 2-Flute Centre Cut, 6mm Shank - TECWERK

Benefit from the combination of HSS‑Co8 substrate, TiCN coating and a Weldon shank for extended tool life and secure clamping — order the Slot Drill Type N, 3 mm via Metav Werkzeuge or consult our technical advisors for application support.

TECWERK Slot Drill Type N, 3 mm — HSS‑Co8, TiCN‑coated, Weldon shank

The Slot Drill Type N, 3 mm is a long two‑flute, centre‑cutting end mill designed for slotting and plunge operations in materials up to approximately 1000 N/mm².

• HSS‑Co8 with TiCN coating for long life
• Two‑flute centre‑cutting geometry
• Weldon cylindrical shank Ø 6 mm
• Suitable for steel and stainless up to ~1000 N/mm²

Durable cutting life for repetitive production

The combination of HSS‑Co8 (8% cobalt) and a TiCN coating delivers increased red‑hardness and improved wear resistance compared with uncoated high‑speed steels. For repetitive slotting tasks the result is consistent edge retention and reduced tool-change frequency, which supports throughput and lowers total machining cost. The selected substrate and coating are particularly beneficial where intermittent contact and higher temperatures occur during slotting of medium‑strength steels.

Confident plunge and slotting performance

With its centre‑cutting geometry and two‑flute design, the cutter enables reliable plunge starts and controlled chip evacuation from narrow slots. The short relief of 2.9 mm ensures a stable cutting edge in restricted depths, while the two‑flute form balances rigidity with efficient swarf removal. This configuration is well suited for producing clean slot walls and accurate slot widths in shorter‑to‑moderate slotting operations.

Secure clamping and machine compatibility

The Weldon cylindrical shank with drive flat and Ø 6 mm shank diameter provides a secure mechanical drive in standard holders and setscrews, reducing the risk of slippage under higher torque. The long version of the cutter maintains reach for deeper features while retaining the clamping reliability expected in production environments. The right‑hand cutting direction matches common spindle arrangements and simplifies toolpath planning.

Material suitability and practical guidance

Engineered for robust performance, the cutter shows very good suitability for steel, stainless steel (INOX) and cast iron, with conditional suitability for non‑ferrous metals and special alloys; it is specified for materials up to approximately 1000 N/mm² tensile strength. For best results, select conservative feeds when cutting harder alloys and employ adequate coolant or high‑pressure coolant where permissible to extend tool life. The tool’s centre‑cutting characteristic also allows cautious plunge milling when required by the application.

FAQ

Is the cutter suitable for plunge milling?
Yes. The TECWERK Slot Drill Type N (SKU 2000866152NW) features a centre‑cutting geometry that permits controlled plunge starts and short plunge operations.

What shank size and clamping type does the tool require?
The cutter has a 6 mm cylindrical shank with a Weldon drive flat, designed for secure clamping in set‑screw holders and Weldon collet systems.

Which materials offer the best results with this cutter?
Best results are achieved in steel, stainless steel (INOX) and cast iron; the tool is specified for materials up to roughly 1000 N/mm², while non‑ferrous metals and special alloys are conditionally suitable.

How does the TiCN coating affect performance?
The TiCN coating increases surface hardness and reduces built‑up edge, improving wear resistance and cutting stability for repetitive slotting tasks on medium‑strength materials.

Is this a standard or long version of the cutter?
This is the long version, offering extended reach for deeper slots while maintaining a Weldon shank for secure drive.
