5mm Core Slot Cutter DIN 844 Type N HSS-Co8 Long 3-Flute Centre Cut, Weldon Shank - TECWERK

Benefit from the combination of HSS‑Co8 durability, a three‑flute centre‑cutting geometry and a secure Weldon shank for dependable slotting and plunge operations; order the tool directly via Metav Werkzeuge or consult our specialists for application advice.

Slot drill DIN 844 Type N — long, three‑flute, HSS‑Co8 with Weldon shank (TECWERK)

Slot drill DIN 844 Type N serves as a long, centre‑cutting milling cutter designed for slotting and plunge operations in medium‑strength engineering materials.

• HSS‑Co8 high‑cobalt construction
• Centre‑cutting for plunge and slotting
• Weldon cylindrical shank with drive flat
• Very good for steel and cast iron

Precision and material performance for consistent slotting

The HSS‑Co8 alloy combines heat resistance and toughness to deliver stable cutting under intermittent loads. Its three‑flute geometry balances chip evacuation with axial strength, while the centre‑cutting design enables controlled plunging without the need for a pilot hole. For uncoated conditions the cutter is suited to materials up to 800 N/mm², with coated variants extending capability to about 1000 N/mm². These properties make the tool a sound choice where repeatable slot dimensions and surface integrity matter.

Faster set‑ups and reliable drive transmission

A Weldon shank with drive flat ensures secure torque transfer in standard collets and chucks, reducing slippage during aggressive slotting. The modest shank Ø 6 mm and the standardised tolerances specified for nominal diameters support consistent clamping and interchangeability across fixtures. The right‑hand cutting geometry provides predictable chip flow and simplifies process planning, helping to shorten set‑up times and reduce rework in batch production.

Clear guidance on material suitability and coating choices

The cutter demonstrates very good performance in steel and cast iron, while non‑ferrous alloys and stainless steel (INOX) are listed as conditionally suitable depending on cutting data and coolant strategy. Choosing a coated version extends the working range to tougher grades (up to 1000 N/mm²) and improves wear resistance in dry or high‑temperature applications. For plunge operations, the centre‑cutting profile must be paired with appropriate feed rates and stable workholding to exploit the cutter’s geometry safely and efficiently.

Workshop reliability and workflow benefits

Built to the DIN 844 specification and produced for long runs, this long‑reach slot cutter reduces the need for frequent tool changes and supports continuous operation in small to medium series. The combination of material choice and geometry aims to minimise tool failures and maintain part tolerances. For purchasers seeking dependable supply and technical backing, Metav Werkzeuge provides procurement from a European stock combined with specialist advice to integrate the cutter into existing workflows.

FAQ

Is this cutter suitable for plunge cutting?
Yes. The slot drill features a centre‑cutting geometry that permits controlled plunge operations; the design is intended for slotting and axial entry.

Which materials are best matched to this tool?
The TECWERK slot drill shows very good performance in steel and cast iron; non‑ferrous metals and stainless steel are conditionally suitable depending on cutting data and coating.

What does HSS‑Co8 mean for workshop performance?
HSS‑Co8 denotes a high‑speed steel with approximately 8% cobalt, providing improved heat resistance and toughness for intermittent cutting and extended tool life.

What shank and clamping should be used?
Use a secure clamp or collet compatible with a 6 mm shank and accommodate the Weldon drive flat to prevent axial or rotational slippage during slotting.

Are there nominal diameter tolerances specified?
Yes. The documented nominal diameters 9, 11, 13 and 15 mm are supplied to tolerance h10; other sizes are to e8 as specified.
