There’s a drill bit that is designed for every type of hole and material. You need a different drill bit for every project. While there are different kinds of drill bits, they usually consist of the same parts. Most drill bits start with a tip or the spearhead of the bit. The lips of the bit are the spiraling cutting edge that usually determines the overall aggressiveness or temperament of the drilling action.
The channels spiraling beneath the lips are called the flutes and it serves as passages for material ejection.
The spiral of the drill bit consists of the flutes and lips. It controls the rate of material ejection while drilling and the quality of the ensuing hole. The shank is the piece of drill bit that fits into the drill chuck. It’s usually roundish and smooth. Each part contributes to the bit’s general behavior. For instance, drill bits designed for aggressive drilling will have a different lip and tip angle than bits made for precision work. Drill bits designed for metal will physically differ from those made for ceramics. You have to be careful when choosing drill bits. Here are the best drill bits that you can find today.
