There is no single best diamond cutting disc for all applications
Unfortunately, this is an undeniable fact (and the same applies, by the way, to resin-bonded cutting discs and grinding discs). Here, too, quality and performance are the result of the interaction between the material and the tool, combined with proper use.
We’ve put together a few useful and easy-to-follow tips for you so that you, too, can boost the performance of your diamond cutting disc, make the right choice, and at the same time maximize the lifetime of this tool, which isn’t always cheap.
Problem: The blade isn't cutting or the blade is getting dull
Diamond cutting disc is clamped incorrectly
- Note the direction of rotation arrow
Excessive pressure during cutting
- Apply less pressure while cutting
The diamond blade has too much hardness for the material being cut
- Use a cutting disc that is suitable for the material being cut
Problem: Short service life (excessive wear)
The diamond blade is not suitable for soft, abrasive materials
- Use a cutting disc that is suitable for the material to be cut
Insufficient drive power for proper cutting performance of the diamond blade
- Use a machine with higher drive power
Problem: Disc overheats
Using a diamond blade with too high a hardness for the material being cut
- Use a cutting disc that is suitable for the material being cut
Insufficient cooling of the cutting disc
- Wet cutting: Ensure sufficient water supply and flow
- Dry cutting: Remove the cutting disc from the cut every 10–15 seconds and let it run freely
Blue discolouration on the blade
- Reduce feed speed
- Take cooling breaks
Problem: Segment loss
Undercut, wear of the steel core beneath the segment
- Wet cutting: Use sufficient water to flush out abrasive particles
- Check the steel core regularly and replace the disc in a timely manner
- Use a disc designed for abrasive materials (hammer segment/angled segment)
Disc tilting
- Secure the material properly and align the machine straight; mark the cutting path if necessary
Use of a diamond blade with too high a hardness for the material being cut; strong vibrations lead to material fatigue
- Use a cutting disc suitable for the material being cut
The right type of cutting edge for your application
The shape of the cutting edge also plays a decisive role in determining the cutting performance of the diamond cutting disc as well as the feel of the cut during use. The choice of the diamond tool best suited to your specific application depends on more than just the material being cut.
Closed cutting edge
ensures precise cuts and very clean cutting edges.
Turbo cutting edge
combines a clean cutting edge with short cutting times.

Segmented cutting edge
Highest cutting speed and maximum service life thanks to segment heights of up to 17 mm.
