Overloading a drill press may result in:

• Damage or breakage to the drill bit, affecting its performance.
• Increased strain on the drive components, potentially causing premature wear or failures.

Excessive friction in a guillotine can cause:

• Increased wear and tear on moving parts, leading to decreased operational efficiency and longevity.

The negative effects of friction on a horizontal band saw include:

• Overheating of the cutting blade, which could compromise its integrity.
• Damage to the cutting blade itself, affecting cutting precision.
• Excessive wear on moving parts, which can lead to mechanical failures.

1. Regularly check the mains electrical switches to ensure they are functioning properly and are free of damage.
2. Inspect the wiring and conduits for any signs of cracks or wear to prevent electrical failures and maintain safety.

1. Apply cutting fluid to the drill bit to minimize friction and heat generation during operation.
2. Ensure that the drill bit is sharp, as a sharp bit reduces resistance and makes drilling easier.
