How to change the drill bit of an electric drill

If the drill bit of the electric drill fails, is damaged, or needs to be replaced according to the material of the hole, such as replacing the tile drill bit when drilling tiles, do you know how to change the drill bit of the electric drill? Different types of drill bits have different operation methods and replacement methods. Many friends do not know how to replace them, so this article will talk about 4 ways to replace the drill bit based on the commonly used drill bit types.

How to change the drill bit of the electric drill-hand-tight type

The drill bit position of the hand-tight electric drill is all made of steel and has a steel gear structure. Generally, this kind of hand drill will be given a "key". Insert the "key" into the small hole at the front end of the electric drill to loosen the electric drill and replace the drill bit.

Specific steps: prepare relevant tools, such as the drill bit to be replaced, electric drill key, etc.; stand the electric drill upright, hold the toothed swivel below and loosen it, and the bite mouth on the drill bit will loosen; when the bite mouth is opened to the size of the drill bit, you can insert the drill bit, and pay attention to put it in the middle of the three bite columns, and then reverse the loosened swivel so that it can bite with the drill bit rod; if the drill bit is relatively small, the electric drill bite column will extend a little when it is clamped. This is very normal; after the electric tooth ring clamps the drill bit, use the electric drill key to insert it into the small hole on the steel ring on the electric drill, and then turn the key to tighten it. This operation is required for several holes; after each hole is tightened with the electric drill key, the electric drill bit is installed. When disassembling, you must also use the electric drill key to loosen the hole.

How to change the drill bit of an electric drill-self-tightening type

Self-tightening electric drills generally use threads to fix the drill bit. The front part of the drill bit is plastic with anti-slip patterns. Hold the anti-slip textured plastic bolt at the front with your hand, preferably wearing thick gloves, then slow down the speed, press the switch, and you can grab the "three claws" of the drill bit at the front end to open it, and then put the new drill bit in, and then reverse the operation.
