Read the following guidelines to help you choose a cordless screwdriver
What is a Cordless Screwdriver?
Cordless screwdrivers operate like a typical drill but with less power and a slower speed. They are also smaller and more lightweight than cordless drills. The power of cordless screwdrivers is measured by the voltage of their batteries. Smaller and more compact models can run on 3.6 volts. Their sizes range from very compact models the size of a flashlight that run for about 6 volts and require just AA batteries. These models are designed to screw and pull out a screw but not to drill. The usual speed for these small screwdrivers is 250rpm. Smaller ones are cheaper (about US$10) than larger and powerful models.
Larger models combine a drill and screwdriver in one. They run on rechargeable batteries and require about 12 volts. Normally the speed for large cordless screwdrivers is 500rpm which is enough to drill. They are more expensive than compact models, fetching about US$20 to US$40. Although they resemble cordless drills a lot, larger cordless screwdrivers are way lighter. They weigh about 2lbs each.
Advantages of Cordless Screwdrivers
Unlike corded models, cordless screwdrivers can be used in areas where there is no source of electricity available. You can use it outdoors without the need for cable extensions. Also, it allows you to angle and maneuver it in awkward angles because it is lightweight. You can even install a ceiling fan with it. It is safer to use a cordless screwdriver because it poses no risk of toppling objects over and getting tangled with other devices. When working on a project involving other people, cordless screwdrivers do not clutter your workspace with cables that can cause other people to trip.
As mentioned earlier, they are available in very compact and larger models. This offers the user versatility. You can buy both small and large cordless screwdrivers. Use a compact model on appliances and a larger model on making your own cabinet, desk, or even artisan work. The last but not the least, it saves you time and effort.
Battery and Run-time
As mentioned earlier the voltage of cordless screwdrivers varies from unit to unit, typically around 3.6 to 12 volts. The run-time depends on the machine’s voltage. The versatility of cordless screwdrivers allows the user to use it not only to drive, drill and remove screws but also nuts and bolts. Each resistance it encounters also contributes to its run-time.
Cordless Screwdriver Bits
Each screwdriver bit is attached to a hex chuck. That is the part that accommodates all kinds of screwdriver bit to be used for drilling. Each bit has a ¼” hex shank that fits into a ¼” hex chuck. There are three kinds of bits: insert bits, power bits and double ended bits. Insert bits have a short shank and is clipped to a magnetic bit holder. Power bits have a longer shank and can fit into a drill’s chuck without the magnetic bit holder. Double ended bits have a screwdriver bit on both ends.
Types of Bits
Cordless screwdrivers have a basic set of 11 bits, more if each of those bits would come in various sizes. A basic bit set would contain the following bits:
- Philipps bit
- Pozidrive bits
- Slotted bits
- Tamperproof Torx bits
- Torx bits
- Square recess bits
- Internal hex bits
- Driwall bits
- Tri-Wing bits
- Torq bits
- Trilobular bits
- Spanner bits
As mentioned, cordless screwdrivers can also tighten nuts. This can be done by attaching socket adaptors. They are available in three sizes: ¼”, 3/8 and ½”. A word of caution: cordless screwdrivers are designed by manufacturers to work with screws. Damage caused by socket adaptors are not covered by the manufacturers’ warranties.
Clutch, Speed and Additional Features
Not all cordless screwdrivers have a clutch. Clutches are helpful by disengaging the device once a certain amount of depth and resistance has been met. This would prevent the machine from overworking itself. Also, clutches allow the user to set the drilling depth so there would be no need to guess how long you should hold down the trigger button.
When purchasing a cordless screwdriver for serious or professional needs, opt for a unit with variable speed triggers. This would allow you to progress from slow to high speed performance.
Customer and Aftersales Services
A cordless screwdriver is a must-have in every home. Even though there are cheap and compact models available, whatever you purchase, make sure that it comes with a good customer and aftersales service. Inquire if the store offers a return or does repairs. If they don’t, make sure you know where to get your cordless screwdriver repaired. Some online sellers offer free shipping and there are parts available if you’re sure that you can repair it yourself. A word of advice: opening up your device can void its warranty. Unless it isn’t past its warranty, have it repaired in the manufacturer’s repair center. If the store allows testing, have one tested.
