Slant lap grinders · independent specification review
Hi-Tech Diamond 6-Inch Slant Cabber — Rock Kit
The rock/mineral six-inch slant lap, correctly labelled with a coarse-to-polish stone kit rather than the finer glass-disc bundle.
This version is easy to mistake for the glass kit because the machine body is the same. The difference is the abrasive package: it starts at 180 grit for shaping stone, then moves through resin discs and polish. That makes it the better choice for cabochons and minerals, not delicate glass finishing.
Reasons to choose it
- Cabochons, stone and mixed lapidary work on a compact bench
- 6 in slanted lap
- 800–3,400 RPM
Consider before buying

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
Four dedicated backing plates simplify grit changes, but contamination control still decides the finish. Rinse the work and hands between stages and keep the coarse disc away from the polishing pad.
Compare glass/crystal and rock/mineral replacement disc kits.
Who it suits
This is a strong shortlist candidate for cabochons, stone and mixed lapidary work on a compact bench. The useful question is whether that describes most of your work, not merely one future project.
When another tool makes more sense
Choose the glass/crystal Slant Cabber when fused glass and fine edge polishing are the main work; choose a six-wheel cabbing station when changing discs interrupts production.
