Hi-Tech Diamond 8-Inch All-U-Need — Glass Kit
The eight-inch glass/crystal All-U-Need adds useful support area while retaining the fine 360-to-3,000-grit sequence glass workers actually need.

This is the horizontal counterpart to the eight-inch glass Slant Cabber. The larger lap face supports broad fused pieces and straight edges more comfortably than a six-inch disc, while the glass bundle avoids buying a coarse stone kit and replacing most of it immediately.

What ownership is actually like
The small machine footprint is slightly misleading: eight-inch backing plates and clean grit storage need a wider dry area. Separate every stage and inspect for stray coarse particles before the polishing pass.
Who it suits
This is a strong shortlist candidate for larger glass faces and a fine horizontal polishing sequence. The useful question is whether that describes most of your work, not merely one future project.
When another tool makes more sense
Choose the six-inch glass All-U-Need to control cost and storage, or the angled eight-inch Slant Cabber if contact-point visibility is the recurring difficulty.
