Nowadays, most cordless electric drills are also designed to drive screws, which is why they are called electric drill drivers. If you have never used a screwdriver before, or tried it without much success, then here is a complete guide to using a drill bit to drive a screw.
This passage is going to talk about the followings of using electric drill for screws:
(1) What kind of drill bit do I need?
(2) Which drill speed is best for driving screws?
(3) Choose the correct action settings
(4) What is the torque setting?
(5) What if the electric drill does not stay on the head of the screw?
First choose the right drill bit for the screws you need.
The type of drill you need depends on the shape on the screw head. The most common is the star-shaped Phillips head. For this, you need to use a No. 2 Phillips head screwdriver, which is the correct size to fit most of these screws. Other common drive bits you will encounter are internal hex drives for bell mouth slat screws; square drive bits for mounting screws and nut hex keys that can be mounted on roof screws.
Then choose the right speed for your drill.
Low speed can control the driving screw to the greatest extent, especially for beginners. If you use a Phillips screwdriver, it will not lock on the head of the screw like other types of screws. Once you get used to using the drill bit as a screwdriver, you can try to increase the speed to get the job done faster.
Do not forget to select the correct action setting on the electric drill.
The action setting is a switch on the drill bit with pictures of screws, hammers and drill bits. Turn it to the screw setting, which means the bit is ready to drive the screw. Other settings are used for regular drilling and to put the drill in hammer mode when you drill into bricks or concrete.
Choose the appropriate torque setting.
The torque setting is an adjustable collar with many numbers on the drill. Torque is the rotational power of the drill bit, and the torque setting allows you to control how much force is applied to rotate the screw. Setting the drill bit to the correct torque setting will mean you will not overtighten the screw. Test at the beginning of the job to get the correct settings for the job you are performing. Generally, soft materials need a low torque setting, while hard materials need to be set to a higher value.
This usually happens with Phillips head screws because the head of the drill bit will not lock in the screw like other drill bit types. If it does happen, stop immediately. The drill bit will not lock the screw, the final thing you have to do is to peel off the head of the screw and cause bigger problems. The followings are a guide for driving Phillips head screws:
Check if your drill is in good condition. Worn drill bits are unlikely to remain on the head of the screw.
While driving, continue to press the bit to keep the bit in the screw. When you are close to the material to be screwed in, do not relieve the pressure, maintain the pressure, and allow the torque setting to stop the drill in the correct position.
Do not try to continue to slip some screws that have already slipped. Pull it out and get a new one.
