TECWERK Keyway cutter DIN 327 Type N — 12 mm HSS‑Co8, TiCN, Weldon shank

The TECWERK Keyway cutter DIN 327 Type N, 12 mm is a short, three‑flute, centre‑cutting tool designed for milling pass‑fed keyways and slots in steels, stainless steel and cast iron.

• TiCN coating for extended tool life
• HSS‑Co8 high‑cobalt substrate
• Short three‑flute design for rigidity
• Weldon shank 12 mm for secure clamping

Precision keyway milling with durable geometry

The short three‑flute design is engineered to combine rigidity and cutting efficiency: the three cutting edges distribute load evenly, reducing vibration and improving surface finish when producing keyways. Constructed from HSS‑Co8, the tool offers increased hot hardness compared with standard high‑speed steels; the TiCN coating further reduces abrasive wear and friction, which translates into longer intervals between tool changes. As a centre‑cutting tool compliant with DIN 327 Type N, it is suitable for plunging and peripheral milling operations where accurate slot depth and consistent flank geometry are required.

Stable clamping and repeatable accuracy on shafts

Clamping stability has a direct impact on concentricity and repeatability; the Weldon shank (12 mm) provides secure axial locating for high‑torque operations and quick changeover in production settings. The cutter’s dimensions—overall length 73 mm, effective length 26 mm and a cutting length of 3 mm—are balanced to keep overhang to a minimum, increasing stiffness and reducing the risk of chatter. The specified relief length 11.5 mm supports clearance during slotting, while the right‑hand cut direction matches standard spindle rotations for routine setups on milling machines and machining centres.

Reliable material suitability and practical performance

This short slot cutter was developed for demanding workshop and industrial use: material compatibility is excellent for general steels and notably very good for stainless steel and cast iron, while non‑ferrous metals and special alloys are rated as conditionally suitable. Performance guidance from the technical data indicates capacity for work up to approximately 800 N/mm² with uncoated geometry and up to 1,000 N/mm² when the TiCN coating is applied. The centre‑cutting geometry allows safe entry into slots, which is particularly useful when machining keyways to precise depths without pre‑drilling.

Efficiency, service continuity and advised application

The combination of a cobalt‑alloyed substrate and hard surface coating helps to reduce downtime through extended tool life, lowering the frequency of replacements and supporting continuous production. For workshop operators and purchasing managers seeking consistent supply and technical backing, Metav offers expertise and a central European logistics hub that acts as a quality filter for stock. For specific machining parameters, secure clamping recommendations or application checks for coated versus uncoated use, the technical advisers at Metav are available to provide tailored guidance and ensure the cutter is matched to the machining task.

FAQ

Which materials can be machined with this cutter?
The TECWERK keyway cutter (DIN 327 Type N, SKU 2000866212NW) is very well suited to steel, stainless steel and cast iron; non‑ferrous metals and special alloys are conditionally suitable.

Is the cutter suitable for plunging operations?
Yes, the tool is centre‑cutting (DIN 327 Type N) so the TECWERK keyway cutter can be used for plunging as well as peripheral milling.

What clamping system is required?
A secure Weldon clamping system is recommended for the 12 mm shank to ensure axial stability and repeatable concentricity during keyway milling.

How does the TiCN coating benefit production?
The TiCN coating on the TECWERK cutter reduces abrasive wear and friction, which improves tool life and maintains cutting edge integrity under higher workpiece strength conditions.

Can this cutter produce deep keyways?
The short three‑flute geometry and 3 mm cutting length are designed for stability and accurate keyway profiles; for deeper keyways, multiple passes or alternative lengths should be considered.
