What is the speed of an electric drill?
In addition, when the drill is in use, it usually starts at low speed to contact the surface of the object and then accelerates slowly after being drilled.
Like the gears in the car, the high speed traction is small, but the speed is fast; the low gear traction is large and the speed is slow. The high speed electric force is small, but the drilling speed, suitable for easy drilling objects, such as plastic, wood or drill drill small holes; low speed force, but slow drilling speed, suitable for drilling hard materials and drilling large holes, such as iron, must use low speed.
According to the object to be processed (such as different materials, drilling diameter size), choose a different speed. Drilling hard materials, large holes, you need to choose low speed; drilling soft materials, small holes, you can choose fast.
Can adjust the speed of the drill to drill can sometimes as an electric screwdriver to use, if there is no torque adjustment button, easy to screw the cross slot screw group of flowers, use electric drill speed screw must be tightened quickly when low-speed screw loosen the switch is not so easy to grasp but if long time use of words can also Practice makes perfect.
