- Fired at low temperature (approximately 200°C<392°F>) using synthetic resin, such as phenol resin, as the bonding agent.
- Can be manufactured using ultrafine grains and mixed abrasive grains, which are difficult to use in the vitrified grinding wheels without deformation.
- High impact-resistance and high mechanical strength, such as tension, bendability, and compression strength. This type of wheel is widely used, from precision polishing to rough grinding.
- Because of its high grinding performance, this type of grinding stone can be used wherever a high-precision finish is required, such as the mirror finishing of magnetic heads for audio/video equipment and card readers, or for ferrite cores and edge polishing of optic fiber connectors.
- Thanks to the high holding strength of the abrasive grain, this type of wheel can be used for high-efficiency, high-load, and high-speed grinding. The majority of rough grinding depends on this type of grinding stone.
