What points must be followed for a good use of the screwdriver?

When using the screwdriver, the following points must be taken into consideration:

  • Put the tip on the head of the screw and exert a slight pressure on the screwdriver;
  • Make sure that the tip is inserted straight into the screw head, otherwise the screw could be damaged;
  • Start the screwdriver by pressing the on / off switch;
  • To screw wood screws, first drill a guide hole to facilitate screwing and prevent the piece from splintering;
  • The guide hole serves two purposes. It acts as a guide for the entry of the screw and prevents the wood from becoming distorted or splintering;
  • The guide holes must be drilled to a depth equal to or greater than the length of the
    used screw.
  • Select forward rotation to screw in the screws, and reverse rotation to extract them;
  • Be careful not to overtighten the small brass screws. Their heads are easily twisted and the thread could be damaged. It is recommended to manually tighten these screws;
  • Use Phillips screws whenever possible. They are easier to screw, because the tip of the screwdriver enters more firmly in the head of the screw;
  • To insert a screw in an already threaded hole, start screwing it by hand. Screw the screw until you feel that the thread is gripping, and then use the screwdriver to tighten the screw;
  • To use the screw nuts supplied with the screwdriver, be careful not to over tighten the nuts as they could get damaged.

How can you protect yourself from bit Slipping?

There are four main causes of bit slippage. Let’s see specifically what they are. The first cause is undoubtedly the size of the bit not suitable for the screw; a second cause is the angled application of the bit on the screw. The angle during start-up and the pressure that is too low are the other two causes that cause the bits to slip. Each of these cases leads to an application error. The effects of the bit slipping can cause possible danger of injury to the user; damage to the workpiece; damage to the screw; damage to the bit itself. Such application errors are made very often, so it is important to take the necessary precautions before using the tool.
