Why it remains on our shortlist
Published machine specifications, replacement disc systems and a repair service support the recommendation. The standard machine warranty is one year; consumables are excluded.
Ownership considerations
The ownership jump is mostly in disc cost and storage. Mark every backing plate by grit and never place a polished piece on a contaminated coarse surface.
Compare glass/crystal and rock/mineral replacement disc kits.
Who it suits
This is a strong shortlist candidate for larger cabochons and broad stone faces. The useful question is whether that describes most of your work, not merely one future project.
When another tool makes more sense
Choose the eight-inch glass kit for fused glass, or the CabKing 8 when continuous wheel-to-wheel production justifies a much larger station.
