For Rough Surface Applications
1. Spade Bits
These bits look just as the name suggests. Every shaft terminates into a spade-shaped blade. The spade at the ends is flat and features a sharp point at the very center. This point acts as the guide and helps to center the hole as well as lead the way. Do not be deceived though, the cutting edges are still the part that does the heavy lifting.
It is worth noting that spade bits are probably the cheapest there is on the market and bore holes at great speeds. Their simple design makes them easily modifiable which may come in handy when you need a smaller size bit.

2. Hole Saws
This type of drill bits features two parts the blade and the mandrel. The mandrel in layman terms is the shaft onto which the blade has been attached. It is the mandrel that fits into the drill allowing the unit to be rotated fast and drill holes. The blade, unlike other blades you might be used to is a hollow cylinder that comes with teeth at the top edges.
It is worth pointing out that hole saws are designed to handle work that is in between the prowess of spade bits and saber saws. In addition to being able to drill through wood and plastic, hole saws can also handle other metals including steel, aluminum, and iron. These drill bits for holes in wood are most important when installing cables, conduits, tubing and piping.

As we start out, note that these come in different makes and designs which make them best suited for certain specific uses. These include wood-boring augers, triple fluted wood bits, carbide-tipped auger bits, ice auger, concrete auger and earth auger. From the names, it is quite clear the application each type has been designed for. Of all these types, however, we shall focus on the wood auger bits.
Needless to say, these are perfect and ideal when drilling large and deep holes in thick wooden boards or dry timber. The screw thread added to the tip of the drill bits draw the bit into the material thus eliminating the need to push down on the unit. The single spur cutting edges on the other hand scribe the circumference thus providing a smoother finish.
The large flutes carved onto the design of the shaft help to get rid of the wood chips as the unit makes its way into the cross-section. Many feature a hexagonal shank which helps to provide a secure and firmer connection between the bit and chuck.

5. Installer Twist Bits
To effectively explain this, it is imperative that we start from the basic of what a general twist bit is. These are probably the most common drill bit type designed for handy home use. They are designed for general purpose drilling through plastic wood and some light metal.
Now, that said, installer twist drill bits are of course a type of twist drill bit, only more specialized and made for wiring including security and entertainment systems.
