You should always remove the chuck key from the chart before turning on the power.
Correct Answer
A. Every time
Explanation
The chuck key is a tool used to tighten or loosen the chuck on a power tool. It should always be removed before turning on the power to ensure the safety of the operator. Leaving the chuck key in the chuck while the power is on can cause it to spin and potentially injure the operator or damage the tool. Therefore, it is important to remove the chuck key every time before turning on the power.
2.
Keep the guard over the pulleys and belts unless the drill press is unplugged.
Correct Answer
A. True
Explanation
This statement is true because it is important to keep the guard over the pulleys and belts unless the drill press is unplugged. The guard is there to provide safety and prevent any accidents or injuries that could occur if someone were to come into contact with the moving parts of the pulleys and belts while the drill press is plugged in and operational. Therefore, it is necessary to always keep the guard in place unless the drill press is completely powered off and unplugged.
3.
When should you use a clamp for your stock on the drill press?
Correct Answer
A. Every time you are drilling
Explanation
Using a clamp for your stock on the drill press is important to ensure safety and accuracy. It helps to secure the stock firmly in place, preventing it from moving or spinning during drilling. This is crucial to avoid accidents or injuries caused by the stock slipping or being pulled into the drill bit. Additionally, using a clamp ensures that the drilling is precise and controlled, resulting in better quality and more accurate holes. Therefore, it is recommended to use a clamp every time you are drilling on the drill press.
4.
For control and safety, how far should your hands and fingers be away from the revolving drill bit?
Correct Answer
B. As far as practical, with a minimum of 3 inches.
Explanation
The correct answer is "As far as practical, with a minimum of 3 inches." This answer emphasizes the importance of keeping a safe distance from the revolving drill bit. While the drill press may be considered safe, it is still crucial to maintain a certain distance to ensure control and prevent any potential accidents or injuries. The minimum requirement of 3 inches ensures a reasonable level of safety while operating the drill press.
5.
When drilling a hole into cylindrical stock, hold the stock:
Correct Answer
C. Only drill into cylindrical stock by using V-block or drill press vise to support the stock
Explanation
When drilling a hole into cylindrical stock, it is important to use a V-block or drill press vise to support the stock. This ensures that the stock remains stable during the drilling process and reduces the risk of it slipping or moving. Holding the stock securely by hand may not provide enough stability, and drilling without any support can lead to inaccurate holes or damage to the stock. Using a V-block or drill press vise is the recommended method for drilling into cylindrical stock.
6.
When drilling a long piece of stock:
Correct Answer
B. Place the excess length of the stock to the left of the operator.
Explanation
When drilling a long piece of stock, it is recommended to place the excess length of the stock to the left of the operator. This is because the operator typically stands on the right side of the drilling machine, and having the excess length of the stock to the left allows for better control and visibility during the drilling process. Placing the excess length to the right or in front of the operator may obstruct their view and make it more difficult to handle the stock effectively.
7.
When drilling a deep hole, you should raise the bit; how often?
Correct Answer
D. Both A and B.
Explanation
When drilling a deep hole, it is important to raise the bit both when chips are beginning to block the hole and as often as you need to cool off the bit or add cutting oil. Raising the bit helps to clear away the chips that may be obstructing the hole, allowing for smoother and more efficient drilling. Additionally, raising the bit periodically helps to prevent overheating by allowing the bit to cool off and also allows for the application of cutting oil to lubricate the drilling process. Therefore, both options A and B are correct.
8.
When does the drill bit begin to break through the underside of the stock, you should?
Correct Answer
A. Ease up on the feed pressure
Explanation
When the drill bit begins to break through the underside of the stock, it is important to ease up on the feed pressure. This is because applying more pressure or maintaining the same feed pressure can cause the drill bit to break or damage the material. By easing up on the feed pressure, it allows for a controlled and gradual breakthrough, reducing the risk of any mishaps or damage to the stock.
9.
It is okay to wear gloves when drilling:
Correct Answer
D. It is never okay to wear gloves around rotating machinery
Explanation
Wearing gloves around rotating machinery can be extremely dangerous as the gloves can get caught in the moving parts, leading to severe injuries or even amputations. Gloves can also reduce dexterity and tactile sensitivity, making it harder to operate machinery safely. Therefore, it is important to avoid wearing gloves around rotating machinery to minimize the risk of accidents.
10.
The safest way to remove chips from the drill press workpiece is:
Correct Answer
C. Brush the chips away with a bench or chip brush or a use cheap paintbrush
Explanation
The safest way to remove chips from the drill press workpiece is by brushing them away with a bench or chip brush or using a cheap paintbrush. This method ensures that your hand or breath does not come into direct contact with the chips, reducing the risk of injury or inhaling harmful particles. Using high-pressure compressed air can be dangerous as it may blow the chips towards your face or cause them to scatter, increasing the risk of injury.
