Gryphon Zephyr+ Diamond Ring Saw vs Gemini Apollo Ring Saw

The Gryphon Zephyr+ is the better saw for glass and mosaic work. It has a larger 17-1/2" square work surface, a 6-5/8" throat, and a 7" blade that cuts in any direction, and it converts to a hand-held saw. The Gemini Apollo cuts thicker stock (over 3") and tighter curves (1/2" radius), and it handles tile, stone, metal and acrylic. Owners of both praise the ring-blade design for intricate cuts. The Gryphon's 3-year warranty and included spare blade and parts kit make it the lower-maintenance long-term pick; the Apollo's 1-year motor-only warranty and separately sold blade cartridges are the main drawbacks.

• Choose the Gryphon Zephyr+ if you cut stained glass, mosaics or tile shapes and want a big flat work surface, a detachable hand-held head and a long warranty.
• Choose the Gemini Apollo if you need to slice material over 3" thick, cut 1/2" radius curves, or work stone, metal and acrylic as well as glass.
