Sintered diamond holesaws last a lot longer (about 50x more) than diamond coated holesaws because the diamonds are embedded throughout the segment and fresh ones are exposed as the bonding metal wears away.
These particular ones also have a very thin kerf (thickness of cut) which makes them ideal for precision cuts.
Yes they are more expensive than the same size diamond coated holesaw but quality is remembered long after cost is forgotten.

Glass, marble, jade, greenstone, gem stones, porcelain, ceramic wall and floor tiles, granite, stone and slate etc.

DRILLING TIPS
1. Wet cutting is best, it keeps the holesaw cool making it last a lot longer and also eliminates dust. Use a spray bottle with water while drilling or make a well around the area with plasticine or Blu-tac. Wet cutting is quicker because it flushes out the slurry.
2. If you MUST dry cut then drill 5 seconds and rest 10 seconds to avoid overheating.
3. Never use hammer action it is less effective and the holesaw may be damaged.
4. To get the hole in the right place drill a hole the same size in a piece of wood and clamp it to the work. Remove the template once the holesaw has started cutting. This is a very safe way to cut glass and tiles.
5. Oil after use to prevent rusting.
