Question: 1 / 400

Shaft damage can be reduced or eliminated when a bearing is cut off with a torch by using a ____________.

A straight cutting tip

A blunt cutting tip

A bent cutting tip

Using a bent cutting tip when cutting off a bearing with a torch is beneficial in reducing or eliminating shaft damage. A bent cutting tip allows for more precise control and access in tight spaces, minimizing the risk of excessive heat transfer to the shaft itself. This precision helps prevent overheating, which could otherwise weaken or distort the shaft during the cutting process. By directing the flame more effectively, the bent cutting tip also aids in reducing the size of the cut zone, hence protecting adjacent components from damage and ensuring a cleaner cut.

Utilizing a straight or blunt cutting tip may lead to uneven cuts and increased heat exposure, while a fine cutting tip, intended for intricate work, might not provide the necessary strength for dealing with a dense material like a bearing. Thus, the choice of a bent cutting tip is optimal for maintaining the integrity of the shaft while effectively removing the bearing.
