The label specifies a diameter of 4 mm while the technical details list nominal diameters of 9, 11, 13 and 15 mm; additionally, the stated shank diameter is 6 mm, which does not align with a 4 mm cutting diameter. Because these key dimensions are inconsistent, it is not possible to determine the correct tool geometry, tolerances or suitable applications with confidence. Please provide corrected or clarified specifications (consistent cutting diameter, shank diameter and nominal sizes) so an accurate, compliant description can be produced.

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.

Data inconsistency detected for SKU 2000866244NW: the product label indicates a diameter of 3 mm (D.3mm), while the technical enrichment lists nominal diameters of 9 mm, 11 mm, 13 mm and 15 mm with tolerances h10 for certain sizes and e8 for the remainder. The shank diameter is given as 6 mm, which is incompatible with a 3 mm cutter diameter in typical configurations. The specification also references HSS‑Co8 and a TiCN coating, but the conflicting diameter data prevents reliable correlation of cutting parameters, material suitability and correct shank–tool pairing. Please confirm whether “D.3mm” is a typographical error or which dimension it actually denotes, and reconfirm the intended nominal cutter sizes and tolerances so that an accurate, fully compliant product description and technical data sheet can be prepared.

Product data inconsistent: the label specifies a diameter of D.3 mm while the technical details list nominal diameters of 9, 11, 13 and 15 mm and a shank diameter of 6 mm. This discrepancy creates confusion and makes it challenging to determine the actual dimensions of the product. The lack of alignment between the label and the technical specifications raises concerns about accuracy and reliability. Unable to generate a reliable product description due to these conflicting specifications, as the inconsistency prevents a clear understanding of the product's intended measurements. Please provide corrected and consistent data to ensure clarity and avoid further misunderstandings.
