Choose The Right Drill Size

Wall Drill Specifications

  With the development of the construction industry, people have higher and higher requirements for interior decoration, and in interior decoration, wall drilling is an inevitable task. To ensure that the wall is perforated.It is also very important to choose the appropriate drill size for the effect and safety.

1. The material of the drill bit

The material of the drill bit is the key to determine its hardness and service life. common in the market drill bits are made of high-speed steel, hard alloy, tungsten steel, etc. High speed steel drill bits are suitable for drilling diameter.For smaller cases, carbide drills are suitable for larger drilling diameters, while tungsten steel drills are suitable for deep drilling.

2. Drill diameter

The diameter of the drill bit is the determining factor for the size of the drilled hole. Generally speaking, wall sockets, switches the diameter of the drill bit required for small holes is 6-8mm, and the diameter of the drill bit required for hanging pictures, mirrors, etc. is 8-12mm, and the drilling diameter is greater than 12mm, you need to use a large diameter drill.

3. The length of the drill bit

The length of the drill bit refers to the effective length of the drill bit, that is, the length that can enter the wall.Generally speaking, the thickness of the wall is between 10-30mm, so the length of the drill bit should also be within this within a range. If the drill bit length is too short, it cannot penetrate the wall; if the drill bit length is too long,it is easy to break or the drill bit is deflected.

4. The shape of the drill bit

The shape of the drill is also a factor to consider. In general, the shape of the drill bit is divided into two types, namely flat head and cone head. Flat drill bits are suitable for shallow drilling depths, while cone drill bits the head is suitable for the case of deeper drilling.
