Before operation, the table should be adjusted according to the size of the hole, and the selected drill bit should be installed in the drill card, the tail end should be at the bottom of the drill card, and the drill bit should be installed vertically and fastened. Put the components marked with the ink line on the work surface, clamp them with a clamp, and conduct test drilling. The work can only be carried out after the test drilling is normal.

 When operating, hold the handle with the right hand, drop the drill bit for drilling operation, and gradually increase the pressure until the required depth is drilled. When the handle is lifted, the drill bit is pulled out of the structure at the same time. When drilling through the hole, if it is drilled at one time, a plank should be added under the wood; if the thickness of the wood is greater than the length of the drill bit, first drill half the depth from the back of the wood, and then turn the wood to drill through from the front.
 
When drilling a half hole, the table can be adjusted to the required height and drilled according to the scale shown.

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.
 
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.
