REZ Premium Resin Diamond Wheels: The Ultimate Polishing Solution

Introduction

When it comes to achieving mirror-like finishes on gemstones and hard minerals, the REZ Premium Resin Diamond Grinding Wheel stands in a class of its own. Engineered for lapidary artists who demand the finest results, REZ wheels combine advanced resin bonding technology with high-concentration diamond abrasives to deliver unmatched polishing performance.

What Makes REZ Wheels Different?

REZ (Resin Expandable Zone) wheels feature a soft, flexible resin matrix that conforms slightly to the stone surface during grinding. This unique characteristic allows for:

• More consistent contact between the diamond abrasive and the stone
• Reduced chipping and fracturing on delicate or brittle materials
• Superior surface finish compared to hard metal-bonded wheels
• Longer wheel life due to the self-dressing nature of the resin bond

Available Sizes

Hans Lapidary Tools offers REZ wheels in multiple sizes to fit your equipment:

• 6" x 1-1/2" — Compact size for smaller lapidary machines and bench grinders
• 8" x 1-1/2" — Standard professional size for most lapidary setups
• 8" x 2" — Wide-face option for larger contact area and faster polishing

Grit Range

REZ wheels are available in an extensive grit range to cover every stage from pre-polish to ultra-fine finishing:

• 140 Grit — Aggressive pre-shaping and stock removal
• 325 Grit — Medium grinding and surface refinement
• 600 Grit — Fine grinding; removes scratches from coarser grits
• 1200 Grit — Pre-polish; prepares surface for final polishing
• 3000 Grit — Early polish stage; begins developing surface luster
• 8000 Grit — High polish; excellent for most gemstone species
• 14000 Grit — Ultra-fine polish for hard stones like sapphire and ruby
• 50000 Grit — Final mirror finish; produces exceptional brilliance

Best Applications for REZ Wheels

REZ Premium Resin Diamond Wheels excel in the following applications:

• Cabochon cutting and polishing (agate, jasper, turquoise, labradorite)
• Faceting pre-polish and polish stages
• Glass polishing and edge finishing
• Opal and soft stone polishing where gentle abrasion is critical
• Final finishing on carved gemstone pieces

How to Use REZ Wheels Effectively

1. Always use water — REZ wheels perform best wet. Water cools the surface and flushes away swarf.
2. Use light pressure — The resin bond is designed for light, consistent contact. Heavy pressure reduces wheel life.
3. Progress through grits sequentially — Don't skip grits. Each stage removes the scratches left by the previous grit.
4. Clean between grits — Rinse your stone and hands thoroughly when switching grits to avoid contamination.
5. Inspect the surface — Use a loupe or magnifier to confirm all scratches from the previous grit are removed before advancing.

Care and Maintenance

• Store REZ wheels flat and away from direct sunlight to prevent resin degradation.
• Rinse wheels after each use to remove stone slurry.
• Do not use solvents or harsh chemicals on the wheel surface.
• If the wheel surface becomes glazed, lightly dress with a dressing stick to expose fresh diamond.

Conclusion

The REZ Premium Resin Diamond Wheel is the go-to choice for lapidary artists who refuse to compromise on finish quality. With its wide grit range, flexible resin bond, and compatibility with most lapidary machines, it's the complete polishing solution from rough pre-polish to breathtaking mirror finish.
