The standard length for a new API drill collar is 31' shoulder to shoulder with the pin threads adding an extra 6-8 inches depending on the type of connection.

Yes, a non-magnetic drill collar can be magnetized through various processes such as applying a magnetic field or inducing a magnetic charge. This can be done to aid in drilling operations or to improve the performance of the drill collar in specific downhole conditions.
It's an easy way to limit the depth of your holes.
A collar clamp on a drilling rig is used to secure the drill string during operations, particularly when making connections or changes to the drill string components. It helps to stabilize the drill string and prevent it from falling or shifting, ensuring safety and efficiency while drilling. Additionally, the collar clamp facilitates the handling of heavy equipment and minimizes the risk of accidents in the rig environment.
make a normal drill just leave out the cord
That would depend on what you were drilling and what the project is.
It is a normal, straight drill bit, as opposed to the type with a tapered shank for use in industrial drill presses.
A pillar drill, can be an industrial drill or a DIY hand drill, standing on a single vertical post (THE PILLAR) and a mechanism to lower the drill to the workpiece to drill a hole.
It drills straight holes. In other words it is a perfectly normal drill bit.
No, a non-magnetic drill collar cannot be magnetized because it is specifically designed to have low magnetic permeability. This property helps reduce interference with directional drilling tools that rely on magnetic measurements to navigate the wellbore.
A standard HSS drill bit, slow it down from normal drilling speed.
