The Kola Superdeep Borehole took approximately 19 years to drill, starting in 1970 and reaching its maximum depth of about 12,262 meters (40,230 feet) in 1989. The project aimed to explore the Earth's crust and gather geological data. Despite encountering various technical challenges and high temperatures, it provided valuable insights into the Earth's composition. The borehole remains the deepest artificial point on Earth.
It depends on the drill you use. With diamond drills it can be done in less than two days, but with a cheap, blunt drill, it could take over three weeks.
it depend on the ground level and the kind of hole it is..

Oil workers use advanced drilling technology, such as horizontal drilling and rotary drilling techniques, to produce long drill strings that can reach deep oil reserves. These methods involve using specialized drill bits and equipment that allow for extended reach and precise drilling angles. Additionally, the use of drilling mud helps stabilize the wellbore and cool the drill bit, facilitating the extraction of oil from great depths.
I have a pair of very thin, strong, long nose pliers for that .It almost always works for me.
Drilling to the center of the Earth is a theoretical concept since no drilling project has come close to reaching such depths. The Earth's core is about 3,960 miles (6,371 kilometers) deep. The deepest humans have drilled is about 7.5 miles (12 kilometers) with the Kola Superdeep Borehole, which took over 20 years to complete. If one could theoretically drill straight down at a consistent pace, it would take many decades, if not centuries, to reach the center.
It took 19 years to drill 12,262 meters deep. The crust is 30 miles or 50 kilometers deep.Doing the math:12,262 meters/19 years = 645.37 meters/year50 km = 50,000 meters50,000 meters/645.47 meters/year = 77.47 yearsThis is assuming technology remains at the current level of mining and drilling.
The Earth's mantle begins at a depth of about 30 to 50 kilometers (19 to 31 miles) beneath the surface, depending on location. If one were to hypothetically drill straight down, current drilling technology can reach depths of about 12 kilometers (7.5 miles) in the deepest boreholes, such as the Kola Superdeep Borehole, which took nearly 20 years to complete. Thus, reaching the mantle with existing technology would take an impractically long time, and significant advancements would be needed to achieve this goal.

Drill and tap it for what?
Koalas (which are not bears) are about 23 to 24 inches long.
You can drill holes in aluminum with a drill as long as you have the proper drill bit. Use a regular drill bit and keep speed moderate.
No, a drill bit is quite small and also not a measuring tool. A kilometer is quite a long distance and would be as long as around 10,000 average drill bits.
(trick question? find a more narrow wall.) They sell drill bit extensions - metal rod. OR measure carefully and drill from the other side. Or find a drill bit that is long enough.
These are usually 6 inches long, and have a 1/4" thick part at the base to mount in the drill.

Bitter Kola has some hypertensive properties which means that if you take the Kola along with antihypertensive medications (blood pressure lowering), it could negate some of the effects. But as long as everything is done in moderation and in a consistent manner you should be fine, but you might want to consider checking your blood pressure more till you know how it affects you.
