18mm Slot Drill DIN 327 Type N HSS-Co8 TiCN 3-Flute Short, Weldon 16mm Shank - TECWERK

Take advantage of HSS‑Co8 construction and TiCN surface treatment for extended tool life and precision keyway milling; combine that with a Weldon cylindrical shank (Ø 16 mm) for secure clamping and stable machining. Order the slot cutter directly via Metav Werkzeuge or ask our consultants if needed.

Slot cutter DIN 327 Type N, D 18 mm – HSS‑Co8, TiCN (TECWERK)

A slot cutter DIN 327 Type N designed for precise milling of keyways and deep slots in steels, stainless steel and cast materials

• HSS-Co8 base material with TiCN coating
• DIN 327 Type N, three‑flute short cutter
• Weldon cylindrical shank Ø 16 mm
• Very good for steel and stainless steel

Precision and material compatibility for reliable results

The combination of HSS‑Co8 substrate and TiCN surface treatment provides a balance of toughness and wear resistance tailored for industrial keyway milling. This composition allows efficient machining of materials up to approx. 800 N/mm² with the uncoated geometry and up to 1,000 N/mm² when the tool is used with its coating intact. The specification follows DIN 327, which standardises form and dimensions for slot cutters and ensures interchangeability across setups. For production planning this means predictable tool life and consistent part tolerances when selecting the correct feed and spindle parameters.

Secure clamping and cutting stability to reduce rework

A Weldon shank with a Ø 16 mm diameter and a short, rigid body reduces deflection and vibration during heavy cuts. The three‑flute layout and centre‑cutting geometry allow both peripheral milling and limited plunge operations for keyways, while the right‑hand cutting direction suits conventional setups. These mechanical design choices minimise chatter and improve surface finish, which in turn reduces the need for secondary machining and inspection. The result is a more consistent process and fewer rejected parts.

Productivity advantages in keyway and deep‑slot machining

Designed for milling keyways (Passfedernuten) with greater depth, the tool’s short length increases stiffness, enabling higher metal removal rates in many applications compared with longer cutters. The three cutting edges distribute cutting forces evenly, so material removal is stable and predictable. Use in steel, stainless steel and cast iron is indicated as very good, while non‑ferrous metals and special alloys are conditionally suitable; this targeted suitability helps planners choose the best tool for each job and avoid unnecessary tool changes.

Handling recommendations and process notes for workshop use

To maximise service life, ensure correct clamping in a suitable toolholder and maintain a clean drive flat for the Weldon interface. The TiCN coating improves wear resistance but should be protected from abrasive cleaning methods; inspect edges regularly for wear and re‑index or replace when cutting performance declines. For unclear material conditions or high‑precision tasks, consult process engineers to define cutting data — this prevents cracks, reduces burr formation and keeps tolerances within specification.

FAQ

What materials is this cutter suitable for?
The slot cutter DIN 327 Type N (TECWERK, SKU 2000866218NW) is rated very good for steel, stainless steel and cast iron, with conditional suitability for non‑ferrous metals and special alloys.

Can the cutter plunge as well as mill laterally?
Yes, the centre‑cutting geometry and three‑flute design allow limited plunge operations as well as profile and peripheral milling with the TECWERK slot cutter.

What is the shank size and clamping style?
The tool features a Weldon cylindrical shank with a Ø 16 mm diameter (TECWERK, 2000866218NW), designed for positive clamping in holders with a drive flat.

Which standard does the cutter follow?
The design conforms to DIN 327 Type N, ensuring dimensional compatibility for keyway and slot milling tasks.

How does the TiCN coating affect performance?
The TiCN coating increases wear resistance and permits machining of materials up to approx. 1,000 N/mm² where coating integrity is maintained, improving tool life and process stability.
