To access the centre of the Earth by making a drill hole is 100% impossible as the geothermal gradient does not allow the drilling tool to perform its drilling function. Drilling tool will melt at a specific depth.
No. That's not possible. Although there have some attempts in the past such as the Kola Superdeep Borehole SG-3 which is 12,262 metres (40,230 ft). Although two more attempts were made, one in 2008 at Qatar and another in 2011.
The earth is made up after God created it for life from seven layers:
A - Earth's crust: called the lithosphere and consists of two layers:
1 Sial: Sial consists of low-density continental rocks, composed of lightweight metals with a density of about 2.8 and a thickness of about ten miles, and rising below the seas and oceans to be nonexistent at the bottom of the Pacific Ocean.
2 The bottom layer: Sima, which consists of ocean floor rocks. It is located below the sial layer. Its density reaches 3.4 and is composed of heavy metals. Its thickness reaches about 40 miles, and the layer is separated from the sial. And other five layers with different thikness and density.
How can one reach at least one layer?
It is impossible
There is good information about the subject in the following link:

Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth.
All responses of the colleagues right. The deepest hole which have drilled is less than 15 km. So necessary equipment doesn't built go further, due to high pressure and high temperature. But scientists in seismology, solved the problem in case of the interior of the earth.
Dear Dr. Hazim,
The deepest is 3,777 metres at the Western Deep Levels gold mine in the Transvaal, South Africa. The earth is not spherical and the best approximation is an ellipse rotated about its minor axis, so distance to the centre of the earth varies with latitude. The earth's equatorial radius is 6,378km; assuming this is reasonably accurate for the Western Deep Levels, the depth represents little more than 0.05% of the distance to the centre of the earth, although a latitude correction should be made.
Best regards
Rama

Impossible.
The deepest drilling done: The Kola Superdeep Borehole on the Kola peninsula of Russia reached 12,262 metres (40,230 ft) and is the deepest penetration of the Earth's solid surface.
