Description
More reach, same toughness. The Proxxon large fiber cut-off discs are the bigger sibling to the 7/8" discs — fiberglass-reinforced for near-unbreakable durability, with a 1-1/2" (38mm) diameter that gives you greater cutting depth and reach on thicker stock. Same versatile material coverage: alloyed steel, standard steel, stainless steel, non-ferrous metals, wood, and plastics.

7/8" vs. 1-1/2" — Which Size Do You Need?
The 7/8" discs (No. 28808, 10-pack + mandrel) are ideal for fine, precise cuts in tight spaces and thin stock. The 1-1/2" discs offer greater cutting depth and are better suited for thicker material and longer cuts where the smaller disc would require multiple passes. Many users keep both sizes on hand.
Frequently Asked Questions
Is a mandrel included?
The pack includes the discs with a 2.35mm arbor shaft. If you need a separate mandrel, the 7/8" 10-pack (No. 28808) includes one.
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.
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.
