18mm Hole Spline Cutter HSS‑Co8 TiCN Coating Z2 Short, DIN 327 D, 16mm Shank - TECWERK

Take advantage of a high-cobalt HSS substrate combined with a TiCN coating for extended tool life and reliable performance when machining narrow, accurate slots; order the TECWERK slot milling cutter directly via Metav Werkzeuge or ask our consultants for application advice.

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

The Slot milling cutter DIN 327D Type N is a short, centre‑cutting tool for milling narrow slots and form‑accurate keyways in medium‑strength materials

• HSS‑Co8 substrate, TiCN coating
• DIN 327D Type N, Ø 18 mm, short
• Weldon shank Ø16 mm with drive flat
• Centre‑cutting, 2 flutes, right‑hand cutting

Faster production with robust HSS‑Co8 and TiCN protection

The combination of HSS‑Co8 substrate and TiCN surface treatment provides a balance of toughness and heat resistance that reduces wear under intermittent and continuous cutting. This composition allows consistently high cutting performance and a longer service life compared with uncoated tools, which in turn supports shorter machining cycles and fewer tool changes. The design is optimised for sustained accuracy on repetitive operations, making it well suited to series production environments where material removal must remain predictable.

Secure clamping and axial entry for exact slot geometry

A Weldon shank with a 16 mm diameter drive flat ensures rigid, backlash‑free clamping in standard tool holders, while the centre‑cutting geometry permits controlled axial plunging and entry into pre‑drilled starts. With an overall length of 79 mm, an effective cutting length of 29 mm and a freeshank clearance of 15 mm, the tool maintains stability in constrained setups. The two‑flute geometry balances chip evacuation and surface finish, supporting the creation of precision grooves and keyways with minimal vibration.

Material suitability and application advantages on the shop floor

Engineered to machine a wide range of components, the cutter is very well suited to steel, stainless steel and cast iron, and is capable of handling materials up to approximately 1000 N/mm². Performance on non‑ferrous alloys and certain special alloys is conditional; however, the tool’s short version increases rigidity for deeper keyways and narrow, form‑accurate fits. Conformance to DIN 327D ensures compatibility with established machining standards, and the Weldon shank simplifies integration into existing fixtures for reliable repeatability.

FAQ

What cutting tasks is this cutter best suited to?
This slot milling cutter (DIN 327D Type N) is designed for milling narrow slots, form‑accurate fits and keyways, particularly in steel, stainless steel and cast iron.

Can the tool be plunged axially into a start hole?
Yes, the centre‑cutting geometry allows axial entry and controlled plunging for keyway starts and interrupted cuts.

Which shank holder is required for secure clamping?
Use a tool holder that accepts a 16 mm Weldon shank with drive flat to ensure rigid, slip‑free clamping during machining.

How does the TiCN coating improve performance?
The TiCN coating increases surface hardness and heat resistance, reducing flank wear and extending tool life under higher cutting temperatures.

Is the cutter suitable for non‑ferrous materials and special alloys?
Performance on NE‑metals and special alloys is conditional; machining results depend on alloy composition and cutting parameters.
