Drilling is the process of forming holes in steel and other materials utilizing a drill bit. Delta steel has ability to drill up to 3.5” diameter holes and tap up to 1”. This capability is completed by utilizing either carbide single point, carbide multipoint, or high-speed steel bits along with its coolant from the table reservoir. This coolant also blows away the chips as they emerge from the hole ensuring a smooth finish.
A counterbore is a flat bottomed hole that enlarges an existing hole. It is typically used when a fastener is to be used on a workpiece, the head of which must be either flush with or below the surface of the workpiece.
Reaming is a process that enlarges a pre-existing hole, usually drilled, utilizing a special reaming tool. This ensures a closer tolerance hole than can be achieved by drilling alone.
Tapping is a process that forms threads in a drilled or reamed hole, usually for screws or bolts. The tool used for this process is called a tap.
