You will need a gunsmith to drill and tap the reciever to install a scope mount. Early 22 rifles did not have the dovetail grooves.
For cutting round holes.
A drill bit with a hex shaft rather than a round one.
Used with a router to make detail grooves, normally round bottomed.

To make round cuts in wood, you can use a tool called a hole saw or a spade bit attached to a drill. Simply mark the center of the circle you want to cut, secure the wood, and then carefully drill into the wood using the hole saw or spade bit until you have a clean, round cut. Remember to wear safety goggles and work in a well-ventilated area.
you can cut a hole in wood using a special drill attachment. alternatively you could drill a hole then cut a hole with a jigsaw
Becuase it's hard to drill a square hole.
The smooth round portion of the twist drill that fits into the chuck is known as the shank. This part is designed to securely hold the drill in place while allowing it to rotate. The shank can come in various shapes, such as straight or tapered, depending on the type of chuck it is intended to fit.
The term "tripping the well" got it's start most likely as a reference to the "round trip" made by the drill bit. The first leg of the trip is coming out of the hole, by lifting the entire drill string and unscrewing the upper most drill pipe called a joint, the newly removed drill pipe is laid beside the rig and the drill string is lifted again, etc. until all drill pipe is out of the hole. After service work is performed, for example change to fresh drill bit, then the second leg of the trip is to reverse the process, lowering the drill string as each new joint is made until fully back in the hole with the bit on bottom. You can find a lot of interesting videos on offshore rigs, jobs, etc here: I left the previous answer in place: When drill pipe is lowered or put into the well in the well, it is called running in or is tripping into the well. When drill pipe is raised or pull out of the well, it is call running out or tripping out of the well.

A drill press centering jig for round objects can improve precision and accuracy in drilling operations by securely holding the object in place and guiding the drill bit to the exact center of the object. This ensures that the hole is drilled in the correct location and at the desired angle, resulting in more accurate and consistent drilling outcomes.
