Precise drilling techniques are the first things to learn in woodworking. Modern technology has made it easy to do. The traditional drill is the twist drill. The drilled sawdust can be carried out of the hole by the drill bit. Holes can also be made by the scraping action of a flat drill, which is specially designed for power tools.
There are also hole saws, plane drills, hole saws, etc. Modern drills bring you a lot of convenience.
Power Tool Drilling: The power drill was one of the first power tools.
Jigsaws, circular saws, belt sanders and other tools are then derived. It's hard to imagine how a modern woodworker would work without an electric drill. A hand drill can also be easily mounted on a drill stand to provide precise positioning and verticality.
Most power drills use a drill chuck to tighten the concrete drill bit. They are differentiated by power and clamping range, such as 500W, clamping up to 10mm or 13mm.
The advantage of the flat drill is that it can open large holes: usually 6mm to 38mm holes can be achieved.
The flat drill requires very little torque to operate but some say it is only suitable for normal precision drilling as it will distort the wood fibers. However, it is still widely used.
Prefabricated hole drills are usually not very large in size (less than 6mm). There are also some special prefabricated hole drills, such as hinge drills, which are specially used to drill prefabricated holes when the hinge/hinge is installed.
Electric pistol drills are becoming more common, although they are significantly less powerful than regular drills. Their advantages are easy to carry and use, voltages between 3.6 and 24V and they are low hazard power tools.
The fastest charging time can even reach ten minutes. They are suitable for long field work or working in wet environments.
The drill chuck was also replaced with a quick drill chuck. And they also work as electric screwdrivers. With some accessories they can be extended for more purposes.
1. Twist drill is used for ordinary drilling purposes
2. Tri-point woodworking drill can be positioned precisely
3. Flat drill can open large holes
4. The reamer is used to make countersunk holes to accommodate screw heads, or directly use a countersunk drill to complete the job at one time
5. The cork drill can make short corks to fill the holes in the screw holes.
