Question

When testing an abrasive wheel by tapping the wheel gently with a light, non-metallic instrument you notice that the wheel sounds cracked or damaged. Is it ok to still use the abrasive wheel?

A.
Maybe, if you wear the right protection
B.
No
C.
Yes

Answer 1

The correct option is NO. 
An abrasive wheel with cracked sound should not be used at all, this is because the wheels may fly off during operation and thereby causing serious injury for the user.

Answer 2

Answer:

B. No

Explanation:

A cracked or damaged abrasive wheel is not the correct material to use. It is very important that in any situation where you need to use an abrasive wheel, it is in perfect condition. Cracked abrasive wheels (and damage in general) are very dangerous because they can break or crack further by throwing particles toward you, which will harm your health and could seriously injure you.
