A drilling machine is a tool which we use to cut something. Drilling machines consist of a cutting tool attachment, called the drill bit. This part is the core of a drilling machine, and it’s tip pierces the material and drills through it. There is a base which supports this drill bit and rotates it. So the fundamental process of drilling is rotating the drill bit while pressing it against a material. This results in cutting or piercing of the material.
A drilling machine can also be used to make large holes in comparatively softer materials.Using special drill bits one can make holes in glass.
