Cutting blade vibration
CAUTION: If you use the product with too
much force, the cutting blade can become
too hot, bend and cause vibrations. Use the
product with less force. If the vibrations
continue, replace the cutting blade.
Bonded abrasive cutting blades
WARNING: Do not use bonded 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
materials
Note: Make sure that you use the correct cutting blades
for rail cutting.
Blade type Material
Concrete Concrete, asphalt, stone masonry,
blade cast iron, aluminum, copper, brass,

al.
