Regenerate to produce better: Rolling Tools’ technical proposal for rolls and thread rolling dies

The regeneration of cutting and forming tools represents one of the most tangible practices of industrial circular economy: it enables the functional recovery of high value-added components, reducing energy consumption, raw material waste, and operating costs.

According to ECTA and ISO TC/164, a regenerated tool can reduce environmental impact by up to 60% compared to a new one, with the same mechanical integrity, if the process is certified. Rolling Tools, active since 1986 in the manufacturing of thread rolling tools, fits perfectly within this context.

Rolling Tools’ solution: high-precision regeneration for thread rolls and dies

Rolling Tools has developed an advanced technical service for the regeneration of its thread rolling tools, including:

• • thread rolls for all standard types on the market
  • thread rolling dies
  • segmented rolls

The process involves restoring the working geometries through high-precision grinding and sharpening, combined with optional thermal and/or surface re-treatment. Full traceability is ensured by metrological inspections at both the initial and final stages.

HSS and HQC steels: regeneration compatible only with selected materials

Rolling Tools uses high-performance steels (AISI M2, M42, and special steels with custom compositions) sourced from qualified European suppliers. Proper core hardness, achieved through quenching and tempering heat treatments, is essential to ensure that the regenerated tool delivers the same performance as a new one—especially in applications involving high cyclic loads such as cold forming.

Where required, high-resistance coatings are applied to protect against abrasion and oxidation. These coatings are compatible with the residual microstructure and surface morphology of the tool.

A technical and cost-effective service to support production continuity

Rolling Tools’ regeneration service is designed to integrate seamlessly into the production cycles of fastener manufacturers:

• initial dimensional and metallographic inspection
• regeneration using dedicated CNC machine tools
• heat treatment and surface finishing
• final inspection and internal certification
• integrated logistics (pickup and delivery)

This process helps minimize downtime, reduce tooling costs, and limit the use of strategic raw materials (such as cobalt), delivering tangible benefits also from an ESG perspective.

Rolling Tools’ approach fully aligns with ISO 14001 guidelines and lean manufacturing strategies applied to the fastener sector.
