By Type
Drill bits are usually arranged according to the medium on which they can be used such as metal, masonry, and wood.
Small, pointed tips identify bits designed for wood and if you take a closer look, you will see spurs on either side.
Masonry bits feature come with a slightly sloping tip that is sometimes coated in carbide. This is done to improve their sharpness.
These bits work best with cinder block and stone although they can be used with some tiles as well.
Metal drill bits feature wide-angled points at the end and they may come painted black at times.
If you want the best of such bits, look for those labeled HSS simply because they are extremely versatile. High-end options are usually coated in titanium while others like steel bits will only be ideal for puncturing soft aluminum.
By Size
Did you know that drill bits also come with hole charts to help you identify what size drill bit you need for your particular project?
Such charts are based on the screw shank and should only be used as guides. For instance:
1. You want to use one that is 1/64 inches smaller than your target hole if you intend to create holes on softwood.
2. Go for a bit that is the same size as your hole when dealing with other materials.
3. If you are unsure about what bit to select, pick one that is 1/64 inches larger that the hole you intend to make because that will account for variations regarding screw type and material density.
