A drill bit set containing steel, spiral bits is not very expensive and is almost enough for drilling needs at home. However, they cannot drill into concrete or metal as they require special drill bits. These drill bit sets have drill bits ranging from size eight millimeters to thirty two millimeters. Now if you need to have some concrete or masonry work done then you need the tungsten carbide drill sets as they have the required strength to drill holes through concrete. Mind you, they may be expensive than the regular steel bits.

Another advantage of a power drill is that they can work as screw drivers if you buy special hardened steel bits which have round shank on the top and the bit head is like a regular screwdriver. If you need to have the drill bits for use with nuts and fasteners then you will have to buy a drill bit set which has square base and round shaft. That square base fits into the fasteners and the round hole into the power drill.

For doing drilling into the glass or stained glass then you need to have drill bit set which contains diamond drill bits. These drill bits have diamond either bonded or sintered onto the drill tip which helps drill holes easily into glass. There are special diamond drill bits which can also drill holes into the porcelain tiles.
