Generally speaking, the wood auger drill bit is divided into the three-point drill, twist drill, flat drill, and other types of drill bits. Three-point drill, this kind of drill is relatively common, generally used for wood drilling, it is a kind of screw hole, and some are a tenon hole, the price is not particularly expensive. Its size is large or small, for example, the smallest possible set is 3 mm, and the largest can reach 10 mm. The three-point drill is the best for drilling wood, because it is easy to locate, and the price is relatively cheap, and the price is very high.
As a twist drill, it has a feature that can be used to drill metal because of its high hardness. If you need to drill holes in metal materials, choose a twist drill with a slightly higher price, and its use effect will be better.
Flat drills are mainly used for scraping wooden boards. If the quality of the wooden boards is relatively light, this flat drill is the most suitable. There is also a better quality drill bit that can be used for planing wooden boards.
The above drill bits are some manual drills, and now woodworkers also use electric drill bits, such as the HSS cobalt drill bit. There is also a big difference between the drill bit of the electric drill and the manual drill bit. There are three main types, one is the electric hand drill. This kind of electric hand drill is lighter to use, but because of its relatively small power, the range of use is not particularly large. Generally speaking, it can be used for stacking wood.
