TECWERK Slot Drill DIN 844 Type N — 5 mm, HSS‑Co8, TiCN, Weldon, 3‑flute, long

A TECWERK slot drill designed for plunge and slotting operations in steel and cast materials, featuring a centre‑cut geometry and a Weldon shank for secure mounting in milling holders

• HSS‑Co8 body with TiCN coating
• 3‑flute, centre‑cut design
• Weldon shank, 6 mm for secure clamping
• Suitable for steel, stainless steel and cast materials

Reliable cutting performance for medium‑strength materials

This long version follows DIN 844 Type N standards and uses HSS‑Co8 (cobalt high‑speed steel) to deliver improved heat resistance and toughness compared with standard HSS grades. The TiCN coating increases surface hardness and reduces built‑up edge, enabling the tool to machine materials with tensile strength up to 1000 N/mm² when coated, and approximately 800 N/mm² uncoated. The combination of substrate and coating reduces wear rates and extends tool life, which translates into fewer tool changes and more consistent cycle times in series production.

Secure clamping and geometry that enables plunge and slotting

The cutter’s Weldon shank with a 6 mm diameter provides a positive drive and reduces slippage under torque, essential for narrow‑diameter cutters. The centre‑cutting design allows vertical plunging into material, while the 3‑flute geometry promotes efficient chip evacuation in slotting operations. Right‑hand cutting rotation ensures conventional milling feeds. Together, these features improve dimensional stability and minimise chatter, resulting in cleaner slot walls and reduced rework for precision workshops and toolrooms.

Long reach and compact cutting length for precise grooves

With an overall length of 57 mm and a cutting length of 3 mm (effective length 13 mm), this long variant gives access to deeper pockets and recessed grooves without compromising rigidity at the tool tip. The short cutting length concentrates forces close to the spindle, which supports accuracy in narrow slots and bores. The tool is particularly well suited for machining steel, stainless steel and castings, while non‑ferrous and special alloys are conditionally suitable depending on cutting data and coolant strategy. Compliance with DIN tooling dimensions supports repeatable clamping and interchangeability in standard toolholders.

FAQ

What materials can this slot drill machine reliably cut?
The TECWERK slot drill (slot drill, Type N, SKU 2000866248NW) is very well suited for steel, stainless steel and cast materials; non‑ferrous and special alloys are conditionally suitable depending on cutting data.

Can the tool plunge into material or only mill slots?
The centre‑cutting geometry and 3‑flute design allow vertical plunging as well as conventional slotting, so the tool can be used for both plunge‑type operations and peripheral milling.

What are the clamping requirements for this cutter?
A secure Weldon clamping in a suitable holder is recommended; the 6 mm Weldon shank provides positive drive and reduces slippage during torque‑intensive slotting.

How does the TiCN coating affect performance?
The TiCN coating raises surface hardness and reduces adhesion, extending tool life and allowing machining of materials up to 1000 N/mm² tensile strength when coated.

Is this tool compatible with standard DIN toolholders?
Yes — the design follows DIN 844 Type N dimensions for long cutters, ensuring interchangeability with standard milling toolholders that accept a 6 mm Weldon shank.
