Frequently Asked Questions

• Q: Are these discs compatible with my Inland glass grinder?
  A: Yes — these 5" diamond discs are designed for direct compatibility with Inland brand glass grinders and other 5" twin grinder systems. They are replacement discs for standard Inland grinder models. If you have a different brand of glass grinder, verify your machine's disc diameter and mounting system before ordering.
• Q: What grit should I use for stained glass work?
  A: For stained glass grinding, 60 grit is the standard choice for most cutting and shaping work — it removes glass quickly and handles most pattern shapes efficiently. Use 180 grit for detail work and refining shapes where more control is needed. Use 360 grit for final edge smoothing before copper foiling or leading, producing a smoother edge that accepts foil more cleanly.
• Q: How long do 5" diamond grinder discs last?
  A: Diamond grinder disc life depends on glass type, applied pressure, and water cooling. On standard stained glass, a quality 5" diamond disc typically lasts 100–300+ hours of use. Always use adequate water flow during grinding — running dry significantly reduces disc life and can cause overheating. Replace discs when cutting action noticeably slows or the disc surface appears smooth.
• Q: Can these discs be used for lapidary work?
  A: Yes — 5" diamond grinder discs can be used for lapidary grinding on compatible 5" twin grinder systems. They are effective for grinding softer to medium-hard gemstones (Mohs 5–8) such as glass, opal, and softer minerals. For harder lapidary stones (Mohs 7+) like agate and quartz, use dedicated lapidary diamond grinding wheels rated for higher hardness materials.
• Q: Do I need to use water with these diamond grinder discs?
  A: Yes — water cooling is essential for all diamond grinder disc applications. Water reduces heat buildup, extends disc life, prevents glass from cracking due to thermal shock, and flushes glass particles from the disc surface. Most Inland glass grinders have a built-in water reservoir and drip system — ensure it is filled and functioning before use.
