TECWERK slotting cutter DIN 844 Type N — Ø 9 mm, HSS‑Co8, TiCN, Weldon shank

The TECWERK slotting cutter DIN 844 Type N is a long, three‑flute, centre‑cut tool designed for precision slotting and groove milling in a wide range of steels and stainless materials

• HSS‑Co8 high cobalt steel for durability
• TiCN coating for increased cutting life
• Weldon shank with drive flat for secure clamping
• Centre‑cut three‑flute design for clean entry

Durable materials and coating for longer service life

The combination of 8% cobalt high‑speed steel (HSS‑Co8) and a TiCN coating provides a balance between toughness and wear resistance that is particularly valuable in serial shop work. The cobalt‑alloyed substrate increases red‑hardness and fracture resistance, while the TiCN layer reduces abrasion and adhesion on the cutting edges, allowing the tool to maintain geometry for longer. This translates into fewer tool changes, more consistent slot dimensions and improved uptime for production processes.

Precise geometry for reliable slotting and centring

A three‑flute, centre‑cut geometry with a long flute length enables accurate entry and efficient chip evacuation when cutting slots or keyways. The Weldon shank with drive flat ensures secure clamping in standard toolholders, reducing slippage during heavy engagement. Right‑hand cutting and the cutter’s DIN 844 Type N profile deliver predictable cutting forces and repeatable results, which is essential for maintaining tolerances on critical components.

Clear material suitability and performance limits

The tool is engineered for a broad material spectrum: very well suited for general steels, stainless steel and cast iron; conditionally suitable for non‑ferrous metals and special alloys. With an uncoated geometry the cutter can handle materials up to approximately 800 N/mm², and when paired with the TiCN coating it is rated for work up to around 1,000 N/mm², offering a practical guideline for selecting cutting speeds and feeds in workshop applications.

Workshop practicality and dimensional control

Available nominal diameters include 9, 11, 13 and 15 mm with tolerance h10, while other diameters are supplied to e8 tolerance where applicable. The tool features a 10 mm shank diameter and a free cutting length of 8.5 mm, making it compatible with common collet chucks and Weldon holders. Conformity to DIN 844 ensures standardised dimensions and repeatability, supporting quality assurance processes and easier tool management across multiple machines.

FAQ

What sizes are available for this slotting cutter?
The TECWERK slotting cutter is supplied in nominal diameters 9, 11, 13 and 15 mm (tolerance h10); other diameters are available to tolerance e8 as stated in the product data.

Is the TiCN coating mandatory for machining harder steels?
TiCN coating improves wear resistance and allows the cutter to handle materials up to around 1,000 N/mm²; without coating the cutter is recommended for materials up to approximately 800 N/mm².

Can this cutter be used in standard Weldon toolholders?
Yes, the tool is supplied with a Weldon shank and drive flat for secure clamping in Weldon holders and compatible collet chucks.

Which materials is the cutter best suited to machine?
The cutter is very well suited to steel, stainless steel and cast iron; it is conditionally suitable for non‑ferrous metals and certain special alloys depending on cutting parameters.

Does the cutter allow direct plunge or centring cuts?
The centre‑cut geometry of the cutter enables reliable vertical entry and centring for slotting operations, reducing the need for pre‑drilling.
