Bonded abrasive cutting blades
WARNING:
abrasive cutting blades together with water.
Moisture decreases the strength in the
bonded abrasive cutting blade and the
cutting blade can break and cause injury.
A bonded abrasive cutting blade is made of small
abrasive grains joined with an organic or vitrified bond,
molded with fabric reinforcements, which prevents the
cutting blade from breaking during high speed operation.
Bonded abrasive cutting blades for different

that are made of industrial diamonds.
• Diamond blades are used for masonry, reinforced
concrete and stone.
• Make sure that the diamond blade rotates in the
direction of the arrows shown on the diamond blade.
• Always use a sharp diamond blade.
• Diamond blades can become blunt if you use an
incorrect feeding pressure or when you cut materials

diamond blade it becomes too hot, which can cause
the diamond segments to come loose.
