SAFETY INSTRUCTIONS

Abrasive discs

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