The 100mmx20mm Diamond Felt Polishing Wheel is a professional lapidary polishing tool designed for achieving flawless, mirror-like finishes on gemstones, minerals, glass, and hard stone surfaces. Crafted from dense, high-quality felt impregnated with ultra-fine diamond abrasive, this wheel delivers consistent, swirl-free polishing performance with minimal material loss.
Felt wheels excel where rigid laps cannot—conforming slightly to curved or irregular surfaces while maintaining aggressive polishing action. This makes them ideal for cabochon finishing, faceted stone polishing, and final-stage surface refinement on a wide range of hard materials.
Compatible with standard lapidary machines, grinders, and polishing units, the 100mmx20mm felt polishing wheel fits multiple arbor sizes to suit different machine configurations and polishing requirements.
Key Features
- Diamond-Impregnated Felt Matrix – Ultra-fine diamond particles bonded throughout the felt for consistent, long-lasting polishing action
- Mirror-Finish Performance – Produces high-gloss, swirl-free surfaces on gemstones, glass, and stone
- Slight Surface Conformity – Felt construction adapts to minor surface contours for even polish coverage
- Reduced Heat Buildup – Felt material dissipates heat effectively, protecting delicate stones
- Multiple Arbor Sizes – Fits 1/2", 3/4", 5/8", 1", 32mm, 20mm, and 22.22mm arbors
- Wet or Dry Use – Versatile for both wet polishing compounds and dry finishing

FAQ
-
Q: What polishing compound should I use?
A: Cerium oxide, tin oxide, or diamond polishing paste depending on the material. For gemstones, cerium oxide or 50,000-grit diamond paste delivers excellent mirror finishes. -
Q: Can this wheel be used dry?
A: Yes. Wet use is recommended for heat-sensitive stones. -
Q: How do I select the correct arbor hole size?
A: Match the arbor hole to your machine’s spindle diameter. Common sizes are 5/8" for most US lapidary machines and 22.22mm for angle grinder spindles.
