A Guide for DIY Folks for drilling

By Lance Goodwin

The drill bit market has several types of drill bits available to choose from ranging from low cost to very expensive.

The low cost most inexpensive drill is the regular steel bit which is mostly used in drilling holes in wood. The other types of drill bit are the high speed steel and the titanium coated drill bits. Next in the line which is more expensive but tougher are the carbide tipped and the cobalt bits.

The types of drill bits have been designed for various uses. Let us talk about the twist drill which is used for drill holes into wood, plastic or light metal. Brad Point bit and spade bit are also used for wood but they vary based on the diameter of the hole being drilled.

Another kind of bit which is very common is the installer bit which is used for installing phone wires, TV wires and other cable wires. This is specifically designed so that the wire can be pulled through the hole in the bit.

For drilling holes in copper, brass and aluminum the step bit is used. For drilling holes in glass or tiles the glass bit is used. Masons use a masonry drill which is fixed in front of a rotary hammer or a regular hammer drills.

For doing smaller things in the house you will need a power drill. These drills can easily drill a hole in any household material like wood, glass or even the stained glass.

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.
