Yes. Sea-horses are real. There is actually a site with quite a bit of information on them. I will attach it so you may learn more about them if you wish.
You attach a drill bit into the chuck of the drilling machine.
No. You can attach reins to a halter if you have too. A safer option is the sidepull, which is a leather piece of equipment but does not have a bit, just metal rings on the sides. They are great for horses that can't handle a bit.
You would attach the chin strap (not a chain) to the rings of the bit, between the reins and the cheekpieces. The chin strap won't work like one that is attached to a bit with leverage, but it will help keep the bit more secure in the mouth.
In most braces the jaws have a screw cylinder that clamps around the bit end.
A bridle is the actual mechanism that goes over a horses head. It holds the bit and fits over or around the ears and under the jaw. The reins attach to the bit and are used by the rider for controlling the horse.

A bit is metal bar that is on the bottom of the bridle. This fits inside the horses mouth, behind the teeth, where there is a gap.

for example: unsigned char attach (unsigned char byte, unsigned char bit) { unsigned char mybyte; mybyte = byte&0x7f; if (bit) mybyte |= 0x80; return mybyte; }
a single horsed was attached by two poles. Pairs of horses were attached to a central pole. Four horses were attached in pairs to two poles .
The bit goes on the bridle, not the halter.
