Gryphon Gryphette Glass Grinder
Compact beginner benches
Small and straightforward, the Gryphette suits occasional projects and tighter workspaces.
Five machine families
The right grinder depends on the surface.
These names are often mixed together in listings. This comparison keeps them separate so you can match the machine to the geometry and finish you actually need.
Tight inside curves, pattern fitting and foil-ready edges.
Flat faces, straight edges and staged polishing.
The same disc workflow with a clearer view of the contact point.
Long edges, broad outside curves and repeatable bevels.
Fast rough-to-polish progression on contoured glass and stone.

Four strong choices, each for a different bench.
Instead of making you scan nine near-identical cards, we start with the four clearest use cases. The full comparison remains available when you want every specification.

Compare all 9 grinders →Grinding beyond stained glass
Choose by the shape you need to finish.
A grinder bit fits pattern pieces. A flat lap controls flat faces. A wet belt supports long edges. A cabbing machine keeps a full grit progression ready. This is the distinction most buying pages skip.

Best flat lap for glassFlat lap grinders
Hi-Tech Diamond 6-Inch All-U-Need Glass Kit
Compact glass grinding and multi-stage polishing

Gryphon Wet Belt Sander

Useful evidence, without invented hands-on claims.
Our research desk checks exact model numbers against manufacturer pages, manuals and established specialist suppliers; separates measured specifications from editorial judgement; records when sources were checked; and explains when another model makes more sense. We do not copy Amazon reviews, invent star scores or claim personal testing that did not happen. Prices, sellers and bundles change, so Amazon remains the source for live purchasing information.
