How long does hybrid filament last compared with pure silicon carbide?

Life sits between pure silicon carbide and pure diamond - longer than SiC, at a cost much closer to SiC.

In a pure silicon carbide filament, every grain is consumed by the work. In a hybrid strand, the diamond portion - the most wear-resistant abrasive available - keeps cutting long after much of the silicon carbide has done its job, slowing the overall wear rate.

How to read this

If your current pure silicon carbide brushes wear out too fast on stone, hybrid usually extends change intervals meaningfully without jumping to diamond pricing. Test one brush position first and measure square metres processed per brush - that number decides it.
