It depends on the size of the point of the instrument doing the puncturing (i.e. a needle takes only a little force, but a bullet takes quite a bit). What you really need is how much pressure does it take to puncture skin. I don't believe there is a tested exact amount of pressure required to pierce human skin. One theoretical number taken from the paper linked below is:
(3.183 x10^6 Pa)this is bull **** the femur can't take that much its is really 20000Pa 461.7 PSI (Pounds per square inch)

Depending on the strength of the skull itself, and the density of the bone itself. If you're looking for something that is blunt force, it would require a well tuned striking motion to actually make a hole. However if you are looking for something like a drill, just the same pressure you use to brush your teeth, the machine will do the rest. Sharp objects would require about the same pressure as a punch however. You need to be careful for damaging the brain too much however, the pressure release to the brain itself wont truly do long term damage, but if you hit the brain itself, that's where the damage comes in. Not sure what you're looking to gain from this knowledge, but there it is.
No, it is unlikely for a human to generate the 36 psi required to crush a human skull with their bare hands. The bones in the skull are relatively strong and require a significant amount of force to crush.
The average human possesses around 20,000 to 25,000 genes.
The average human body contains around 37.2 trillion cells.
The average duration of the human gestation period is about 9 months.
It's possible if the BB gun fires with enough force.
It typically takes about 14 psi (pounds per square inch) to puncture human skin. However, the exact amount can vary depending on factors such as the thickness of the skin, the angle of the object, and the force behind the puncture.
you have to put your hand in a toilet and lick it... i try it...it works
Yes it is possible

Go to the aquarium and see
The average pulling force of a human can vary depending on factors such as age, gender, and physical fitness. However, studies have shown that the average maximum pulling force for an adult human is around 90 pounds (40.8 kg) for men and 70 pounds (31.8 kg) for women. This force can be generated through muscles such as the biceps, triceps, and back muscles working together to exert force in a pulling motion.
The force generated by the human jaw can vary, but an average range is around 70 to 150 pounds of force. This force is primarily used for chewing and biting tasks.
At least 15 miles per hr
Yes. 35 pounds is a force that is well below what most humans are capable.
The average bite pressure is in the range of 2840 to 4270 psi. . Therefore, while the bite force itself averaged 117 to 265 lbs, the pressure remained constant at about 5600 psi…certainly enough to puncture light weight sheetmetal.
Machines can change the amount of force needed to move an object by utilizing mechanisms such as levers, pulleys, ramps, and gears. These mechanisms can amplify or reduce the input force applied to the machine, allowing the object to be moved more easily or with greater force than would be possible by direct human effort.
