Frequently Asked Questions

• Q: When should I use a metal bond wheel vs. a resin bond wheel?
  A: Use metal bond wheels for coarse rough shaping (80–220 grit) where aggressive stock removal is needed. Switch to resin bond wheels for fine grinding (600+ grit) and pre-polish stages where surface finish quality matters.
• Q: Can metal bond wheels be used on soft stones?
  A: Metal bond wheels can be used on soft stones but may cut too aggressively. Reduce pressure and use a finer grit (220+) to avoid over-grinding delicate materials like turquoise or malachite.
• Q: How do I dress a glazed metal bond wheel?
  A: Run the wheel wet and apply a dressing stick across the face to expose fresh diamond abrasive. Dress lightly and repeat until the wheel cuts freely again.
