SAFETY INSTRUCTIONS

Abrasive blades

The cutting material in an abrasive blade consists of abrasive
corn that is held together by an organic bonding agent.
"Reinforced blades" are made up of a fabric or fibre base that
prevents total breakage at maximum working speed if the blade
should be cracked or damaged. (The term reinforced does not
refer to those cutting blades that are only reinforced around the
flange).
A cutting blade's performance is determined by the type and
size of abrasive corn, and the type and hardness of the bonding
agent.
Characteristics that give the blade a shorter service life and
greater cutting capacity are said to make the blade "softer". A
blade with a longer service life and slower cutting capacity is a
blade with a "harder" effect.
High quality cutting blades are normally more economical.
Lower quality cutting blades usually have an inferior cutting
capacity and shorter service life, which results in higher cost per
processed material.
