A cordless drill is not just your ordinary tool. The device is versatile enough to handle tasks such as driving screws and drilling holes with ease. It is the perfect gadget for DIY tasks and also heavy duty commercial work. The cordless drill comes in various sizes with small drills costing less. With so many types of drills to choose from, always get your facts right before making any purchase.
Select the right type
Before buying any type of cordless drill, you first need to figure out how you plan on using these tools. Are you planning on mixing concrete? Or are you planning on installing decking, building interior walls, boring out holes, etc..
If you need to mix paint or concrete, don’t waste your time on a cordless drill and buy a corded drill. If however, you’re going to build a deck or shed, etc., a cordless drill is perfect for you — many opt for either a 20v or 18v drill.
Below is a breakdown of cordless drills majoring on the best 18v drill and 20v drills you can find in the market.
Cordless drill/ driver
This versatile nature of the device makes it one of the most popular gadgets. It has unique attributes such as an advanced clutch system that allows users to shift from low speed to high-speed drilling. To make it easier for use in masonry work, the device comes with a hammer drill feature.
Cordless right-angle drill driver
This kind of a drill is unique. It relies on a right-angled gearing to power up the chunk at a 90° angle to the rotating end of the motor shaft. The design feature shortens the chunk tip and the opposing surface on the motor to about 4 inches. With a short chunk tip, the drill is easy to use when working in cramped up spaces.
Cordless impact driver
The driver makes a very unique tap tap sound as it operates. The internal mechanism of the device continuously strikes the rotating shaft creating the sound. Rotational blows make the device very powerful and efficient when working with tough fasteners. This drill is light, compact and less likely to strip your screws.
The striking features of the device are a small size and the light weight. It is a handy tool if you are using small screws and one can comfortably use it for long periods without having to worry about fatigue. In terms of drilling speed, it is relatively slow compared to other drills.
A note about cordless kits
One can either buy a full kit which comes with the driver’s battery and a charger or get each of the items separately. In terms of cost, it is wiser to buy a full kit as this happens to be cheaper.
2: Select a tool that is comfortable to hold
Depending on the nature of your job, you may need to hold a drill for a long period of time. To minimize fatigue, buy a drill that comfortably fits your wrist so that it is easy to hold. A size bigger than your wrist will not only be difficult to hold but on top of fatigue also give you a hard time to operate.
3: Get enough power
The voltage rating of a battery determines how much torque you get from a drill. The standard voltage is mostly between 6 and 36 volts. Interestingly, the more powerful a drill is, the more it is going to weigh. A drill with a high voltage also packs up more power. Considering this fact, light drills are best suited for lighter work. For most users, a 12-volt drill is more preferred for common drilling with an 18-volt device as the ideal choice for heavy-duty tasks.
4: Select the right chunk size
The size of the bit shanks a drill can old depends on the size of the chunk. Even though the standard size of a chuck is ½ an inch, if you plan on digging large holes, go for a larger sized chunk.
5: Check out the speed
Low torque drills have speeds of about 300 to 400rpm. Those that pack a higher torque operate at speeds of between 1200 to 1500 rpm. Technologically a good drill should have an electronic gadget that can comfortably regulate this speed based on the loadings.
6: A clutch lets you fine-tune driving force
The main function of the clutch in a drill is controlling the level of resistance based on the driving force. Once the limit is reached the clutch initiates a protective feature of slipping making a rapid sound. This ensures no additional force is applied. The innovative feature prevents stripping of screws and overdriving the drill which usually results in overheating.
7: Batteries and chargers are key
The power of a drill originates from the battery. Lithium-ion batteries are commonly used due to their superior quality when it comes to performance and also their light size. The Ni-Cad battery is particularly ideal as it costs less and efficiently keeps the charge. Batteries have different voltage and run time. A standard battery usually takes between 15 to 30 minutes to charge depending on whether it is slow or fast charging. For a fast charging battery, you will require using a fast charger. The two will normally cost more. Having two batteries allows you time to charge one as you use the other.
