Quiz Over Drill Press Safety

Explanation
Having a scrap piece of wood under the stock that you are drilling serves as a protective layer between the stock and the table. This prevents the drill bit from accidentally drilling into the table surface, which could cause damage to the table or the drill bit itself. Therefore, it is important to always use a scrap piece of wood as a precautionary measure while drilling.

Explanation
Pulling metal chips from the bit while it is moving can be dangerous and should be avoided. The rotating motion of the bit can cause the metal chips to fly off in unpredictable directions, posing a risk of injury to the person handling the bit or to others nearby. It is safer to wait for the bit to stop moving before removing any metal chips to prevent accidents and ensure personal safety.

Explanation
Small pieces of material should be clamped to the table or held in a vise to ensure stability and prevent movement during various tasks such as cutting, drilling, or sanding. This helps to maintain accuracy and safety while working with small pieces that may be difficult to control by hand alone. Clamping or using a vise provides a secure grip, reducing the risk of accidents and improving the overall quality of the work.

Explanation
Leaving the chuck keys in the chuck while drilling is not safe. The chuck key is used to tighten or loosen the jaws of the chuck, and if it is left in the chuck while drilling, it can get caught in the rotating drill bit and cause accidents or injuries. It is important to always remove the chuck key from the chuck before starting the drilling operation to ensure safety.

Explanation
It is not safe to drill with bent bits on a drill press or hand drill. Bent bits can cause the drill to wobble or become unstable, increasing the risk of accidents and injuries. It is important to use straight and properly aligned drill bits to ensure safe and effective drilling.

Explanation
The statement suggests that if the drill grabs the metal and spins it, one should grab the piece of metal to prevent it from getting damaged. However, this is incorrect. If the drill grabs the metal, it is advisable not to grab the metal as it can lead to injury. Instead, one should turn off the drill and safely remove the metal from it.

Explanation
There is no specific mention of using low speeds while drilling with small drill bits in order to prevent them from breaking. Therefore, the statement is false.

Explanation
Using lubricants while drilling stock is indeed a recommended practice to prevent the bit from heating up and dulling. When drilling, friction is generated between the bit and the stock, which can cause the bit to overheat and become dull. By applying lubricants, such as oil or coolant, the friction and heat are reduced, prolonging the life of the bit and ensuring more efficient drilling. Therefore, the statement is true.

Explanation
The statement suggests that it is false to hold small material free-handed while drilling to prevent breaking the drill bit. This means that it is not necessary to hold small material free-handed while drilling to prevent breaking the drill bit. There may be alternative ways to hold the material securely while drilling, such as using clamps or a vice to ensure stability and prevent accidents.

Explanation
The statement suggests that using gloves while using a drill is a safe thing to do. However, this is not true. Wearing gloves while operating a drill can actually increase the risk of accidents. Gloves can get caught in the drill bit, leading to serious injuries. It is recommended to avoid wearing gloves while using a drill to ensure safety.

Explanation
To ensure safety while drilling, it is important to maintain a sufficient margin of safety from the drill bit. A margin of safety refers to the distance between the drill bit and any potential obstacles or hazards. In this case, a 2" margin of safety would be appropriate, as it provides a reasonable distance to prevent accidental contact with objects or surfaces that could cause damage or injury.

Explanation
When drilling cylindrical stock, it is important to securely hold the stock in place to ensure accuracy and safety. A v-block is a tool specifically designed to hold cylindrical objects firmly and securely while drilling. It has a V-shaped groove that allows the cylindrical stock to be positioned and held securely in place. This ensures that the stock remains stable and prevents any movement or slipping during the drilling process, resulting in precise and accurate holes. Therefore, using a v-block would be the most appropriate choice for holding cylindrical stock while drilling.

Explanation
The long end of the stock should go on the left side of the column of the drill press. This is because the drill press operates with a rotating motion that moves from left to right. Placing the long end on the left side ensures that it will be properly aligned with the drill bit and allows for a smoother and more accurate drilling process.
