  The existence of electric drills makes woodworking work more convenient and labor-saving, but sometimes, hand drills such as Extra Long Wood Drill Bits are more suitable for drilling in narrow spaces, and their controllability is stronger. It is light and noisy when working. smaller. There are two types of manual drills: straight shank drills and crank drills.

  Common drills in woodworking workshops include twist drills, wood drills, hole drills and flat drills. But they all have their own advantages and disadvantages.

  Twist drill: suitable for drilling holes in wood, metal, plastic and (almost) any other material. Twist drills have two shortcomings for furniture production: (1) it is difficult to accurately locate and easily run off; (2) the holes it drills are usually a little oval.

  Woodworking drill: There is a spike in the center of the woodworking drill. The purpose of this design is to allow the drill bit to engage with the wood before the cutting edge of the drill bit touches the wood. Therefore, its positioning is relatively accurate and the drilled hole is also very round. Generally speaking, woodworking drill is the best drill bit used in wood processing, although it cannot be used to drill metal.

  Hole drill: The hole drill can be used in fewer places, but it is very useful. Drill holes too deep. The center spike of the wood drill will pierce the other side.

The disadvantages of hole drilling are slow cutting and rapid heat generation.

  Flat drill: a professional woodworking tool used to drill pipes on the frame. However, flat drills are not very useful for finishing on hardwood. They tend to overheat, cut slowly, and drill holes that are rough and less precise.
