Take advantage of a compact DIN‑standard design with HSS‑Co8 substrate and TiCN coating for extended service life and reliable keyway production; order directly via Metav Werkzeuge or contact their consultants for technical guidance.

Keyseat cutter DIN 327 Type N, 3 mm – HSS‑Co8, TiCN, Weldon shank (TECWERK)

The TECWERK Keyseat cutter DIN 327 Type N, 3 mm is a short, centre‑cutting slot milling tool optimised for precise keyway and narrow slot machining in workshops and small production runs

• HSS‑Co8 substrate for high thermal resistance
• TiCN coating for superior wear protection
• 3‑flute geometry for stable chip evacuation
• 6 mm Weldon shank for secure clamping

Accurate slotting with compact geometry

The short DIN 327 Type N profile gives consistent results when producing deeper keyways and narrow slots. The combination of centre‑cutting geometry and a 3‑flute configuration enables controlled plunge starts and smooth peripheral passes, which helps to maintain concentricity and repeatable fits. With a focus on dimensional accuracy, this cutter is suited to workshops and production cells where part tolerances are critical and rework must be avoided.

Longer tool life through alloy and coating

Built from HSS‑Co8 and finished with a TiCN layer, the tool combines improved hot hardness and abrasion resistance for extended cutting performance. The TiCN coating reduces built‑up edge and improves surface finish under heavier cutting loads; when coated, the cutter can handle materials up to about 1000 N/mm², offering a measurable benefit in life‑cycle costs and fewer tool changes during batches.

Rigid clamping and compatible dimensions

With a 6 mm Weldon shank, 3 mm cutting diameter and overall length 49 mm (cutting length 3 mm, effective length 5 mm), the cutter delivers secure seating and reliable drive transfer in Weldon holders and compatible chucks. The short overhang improves stiffness and reduces the risk of chatter, while the right‑hand cutting direction matches standard spindle rotations in most milling equipment, promoting stable machining and consistent surface quality.

Practical advantages for mixed workshops

Designed primarily for keyway and slot milling, the tool shows very good suitability for steel, stainless steel and cast iron, with conditional performance on non‑ferrous metals and special alloys. The compact design and robust substrate support frequent, repetitive operations, shortening set‑up times and helping to maintain throughput. For tasks requiring secure key fits and reliable cycle times, this cutter supports efficient production workflows.

FAQ

What materials is this cutter best suited to machine?
The TECWERK keyseat cutter is optimised for steel, stainless steel and cast iron (very good suitability); non‑ferrous metals and special alloys are conditionally machinable depending on parameters.

Can the cutter perform plunge cuts?
Yes. The centre‑cutting geometry allows plunge starts and controlled axial entry, so face milling and slot plunges are achievable with appropriate machine settings.

What are the key dimensions and how is it clamped?
The tool has a 3 mm diameter, 49 mm overall length, 3 mm cutting length, 5 mm effective length and a 6 mm Weldon shank for secure clamping in Weldon holders or compatible chucks.

What benefit does the TiCN coating provide?
TiCN increases hot hardness and wear resistance, reduces built‑up edge and extends tool life compared with uncoated HSS, especially under elevated cutting stresses.

Is this cutter suitable for producing standard keyways?
Yes. Designed to DIN 327 Type N with three cutting edges, the cutter is intended for keyway and narrow slot production; refer to the SKU 2000866200NW for ordering and specification confirmation.
