Description
Thin, tough, and versatile. The Proxxon fiber cut-off discs are fiberglass-reinforced for near-unbreakable durability at high RPM — making them safe and effective for cutting alloyed steel, standard steel, stainless steel, non-ferrous metals, wood, and plastics with a Micromot rotary tool. At just 1/32" (0.8mm) thick, they produce a minimal kerf for clean, precise cuts with minimal material loss.

Frequently Asked Questions
Is the mandrel included?
Yes — one mandrel with a 2.35mm shank is included in the pack. No additional hardware needed to get started.
What rotary tools are these compatible with?
These discs fit any Micromot-compatible tool with a 2.35mm collet, including the IBS/E and IBS/A.
Are these safe at high RPM?
Yes — the fiberglass reinforcement makes these discs highly resistant to shattering, unlike unreinforced abrasive discs. Always use appropriate eye protection when cutting.
What do I use after cutting to clean up the edge?
Follow up with a corundum grinding bit for deburring, then the felt polishing bits for a finished surface.
