TECWERK Slot Drill DIN 844 Type N — HSS‑Co8, TiCN‑coated, 3‑flute, 16 mm Weldon shank

The TECWERK Slot Drill DIN 844 Type N is a long, centre‑cutting three‑flute cutter designed for precise slotting and plunge operations in steel, stainless steel and cast iron applications.

• HSS‑Co8 for increased wear resistance
• TiCN coating for extended tool life
• 16 mm Weldon shank with drive flat
• Centre‑cutting three‑flute design for plunge milling

Durable cutting performance that keeps production moving

Manufactured from HSS‑Co8, this long‑reach slotting cutter provides elevated hardness and heat resistance compared with standard high‑speed steel, resulting in longer tool life under intermittent or continuous machining. The TiCN coating further reduces flank wear and adhesion when working at elevated speeds, which translates into fewer tool changes and improved uptime. For workshops seeking consistent process throughput, the combination of a cobalt alloy substrate and a wear‑resistant coating delivers measurable efficiency gains.

Plunge capability and slot accuracy for repeatable components

The three‑edge geometry with centre‑cutting capability permits safe and accurate plunging as well as conventional slot milling. The three‑flute arrangement balances chip evacuation and stability, producing clean slot walls and predictable tolerances. Diameters from the series follow standard tolerancing (smaller nominal sizes with h10, others e8), which supports interchangeability and simplifies fixture design. This makes the cutter suitable where dimensional repeatability for slots and grooves is a production requirement.

Secure holding and vibration‑reduced machining for consistent quality

A 16 mm Weldon shank with drive flat ensures positive clamping in standard toolholders and reduces rotational slippage under high cutting forces. The tool’s long design and a 15 mm free cutting length are optimised to provide access to deeper slot geometries while maintaining rigidity where it matters. These features support reduced vibration and improved surface finish, helping to maintain process stability when machining narrower or deeper slots in series production.

Clear guidance on material suitability and cutting limits

The cutter is rated for materials with low to medium tensile strength up to approximately 800 N/mm² using an uncoated tool and up to 1000 N/mm² when the tool is coated, making it very well suited to steel, stainless steel and cast iron. Non‑ferrous metals and certain special alloys are conditionally suitable and may require adjusted feeds, speeds or cutting strategies. For applications requiring higher performance or different alloys, consultation for machining parameters is recommended to balance tool life and surface quality.

FAQ

What machining operations is this cutter intended for?
The TECWERK slot drill DIN 844 Type N is designed for slotting and plunge milling, delivering centre‑cutting capability for both groove milling and direct plunging.

Which materials can be machined with this cutter?
According to the specifications, the cutter is very well suited for steel, stainless steel and cast iron; non‑ferrous metals and special alloys are conditionally suitable with adapted feeds and speeds.

How does the TiCN coating affect performance?
The TiCN coating on this TECWERK three‑flute cutter reduces adhesive wear and increases resistance to abrasion, which typically extends tool life and allows higher cutting speeds in suitable materials.

What clamping system is required for secure mounting?
A standard toolholder that accepts a 16 mm Weldon shank with drive flat is recommended to prevent slippage and ensure stable torque transmission during slotting operations.

Are there recommended strength limits for workpiece materials?
The cutter is intended for materials up to approximately 800 N/mm² with an uncoated tool and up to 1000 N/mm² when coated, providing guidance for selecting feed and speed parameters.
