4mm Core Slot Cutter DIN 844 HSS-Co8 TiCN Long 3-Flute Weldon Shank, Right-Hand - TECWERK

Benefit from a durable HSS-Co8 substrate, a TiCN coating that extends tool life at higher cutting speeds, and a robust Weldon shank that ensures secure clamping — order directly via Metav Werkzeuge or consult our specialists for application-specific advice.

Slot drill DIN 844 Type N — HSS-Co8, TiCN-coated, Weldon shank, 3-flute (long) by TECWERK

The slot drill DIN 844 Type N is a long, centre-cutting end mill designed for precise slotting and groove milling in steels, stainless steel and cast materials

• High-strength HSS-Co8 substrate
• TiCN coating for longer tool life
• Centre-cutting, three flutes for slotting
• Weldon shank with drive flat for secure hold

Higher throughput through material-matched geometry

The long, three-flute geometry delivers a balanced compromise between material removal rate and surface quality. Built on HSS-Co8 for increased red-hardness, the tool sustains elevated cutting temperatures while remaining dimensionally stable; the TiCN coating further reduces flank wear and allows profitable use at higher speeds. Rated for machining materials up to 800 N/mm² with an uncoated insert and up to 1000 N/mm² when coated, the cutter supports efficient production in mixed-shop environments and contributes to predictable cycle times and lower tool-change frequency.

Secure clamping and consistent chip control

A Weldon shank with drive flat ensures positive torque transmission even under interrupted cuts, reducing slip in the holder and preventing chatter. The centre-cutting design permits plunge starts and reduces the need for pilot holes in slotting tasks, while the three-flute layout aids controlled chip evacuation in medium-depth slots. The combination of shank design and flute geometry results in fewer reworks and improved repeatability on serial parts where tolerances matter.

Clear material suitability and application scope

The tool is very well suited for machining steel, stainless steel (INOX) and cast iron, with conditional applicability to non-ferrous metals and special alloys; users should select coating state according to workpiece strength. In practice, an uncoated tool performs reliably up to mid-range tensile strengths, whereas the TiCN-coated variant expands the capability envelope for tougher batches. For production planning, the cutter integrates smoothly into CNC slotting, repair work and prototype milling where a single tool that combines plunge capability with axial cutting is advantageous.

FAQ

What materials is this slot drill best for? The TECWERK slot drill (DIN 844 Type N) is very well suited to steel, stainless steel and cast iron; non-ferrous metals and special alloys are conditionally suitable depending on the coating and cutting data.

Can the cutter be used for plunge cutting? Yes, the centre-cutting geometry allows plunge starts; the long, three-flute design supports axial engagement for slotting and groove milling operations.

How does the TiCN coating affect performance? The TiCN coating on this TECWERK cutter increases wear resistance and allows higher cutting speeds, extending tool life and improving throughput under demanding conditions.

Is the Weldon shank compatible with standard tool holders? The Weldon shank with drive flat provides secure clamping in holders accepting Weldon tooling, offering reliable torque transmission during interrupted cuts.
