More explanation gets a much better answer.
Physically, this may be an impossibility, given the material you'd be required to drill through, including the Earth's molten core.
When mounting a flag pole on your home, the only tool you would need would be a drill. Depending on the material of the exterior of your home will need to use the proper drill bit as in either mason or wood bit. You will also need the proper drive bit depending on the type of mounting screw that comes with the pole mount.
The cost will be between $700 and $3200 per pole with no guy wire anchors. (in my area) Pole: $500 for a 40 foot pole (in stock) $700 for a 50 foot pole (in stock) $800 hole drilled into rock ………………………………. $1800 for 65 foot pole $1950 for 70 foot pole $1000 to $1200 to drill hole in rock....longer and wider pole so $1000 to $1200 for this. Cost of guy wire anchor is ??????. If you can dig instead of drill, get a backhoe for about $75/hr plus a one time float charge of maybe $60 to $100. So lets say it comes to $200 to put the pole in the ground on a fairly easy dig.
Through the center? Impossible anywhere, since the core of the Earth is molten iron. The shortest PATH would be from pole to pole, but you still have the problem of the molten iron flowing through the core.
To remove the sand from the portable basketball hoop, first see if the pole will come out of the bottom stand where the sand is. If the pole will not come out, drill two holes in the bottom of the stand and let the sand run out.
Yes It could be extremely dangerous to drill at that point. There is no telling where the wires from that panel go. If you drill into the hot wire from the pole, you will be electrocuted because there is no effective ground between it and the ground. It will turn you into barbecued chicken. You can turn off the circuit breakers for any other room in your house where you wish to drill and drill away. You can use an extension cord to a different room for power. Or, you can be buried next to John Wilson.
This is probably either because of poor plant technique, or not a powerful enough run for how high you're holding on the pole. Move down a couple hand holds on the drill, and in the mean time keep practicing plant drills. A better plant also helps your confidence and pole vault is half mental.
The amount of information needed to safely pole vault is truly staggering. Remember to start off very small! Personally, i did drills with a PVC pipe for three weeks before i was allowed to touch a pole. Start by completing simple pole raising drills and move your way up to planting drills, then to a drill with a short jog into a plant. Always remember it is better to vault safely then to try to jump over your limit!
A drill machine can mean a hand held electric drill, or a bench drill press or a pillar drill.
Drill using a 280 degree drill by samsung drill and drill about 5cm by 5 cm
With your drill
It's the part of the drill that holds the drill bit.
