Today, technology is apparently taking over and we are largely dependent on it to make our lives simple and quite easy and to say that cordless drill is one such gift technology has given to us. This portable electric drill machine is well known for its versatile power, preferred by homeowners and tradesmen, it operates with the help of rechargeable batteries with a good battery lasting time, no requirement for any power or electric source as it is easily carried around anytime and to anywhere.
TYPES OF CORDLESS DRILLING MACHINES
Before making a purchase one needs to know about the different types of cordless drill machines available;
- Cordless drill/driver: This is the most popular cordless tool with a variable drilling speed and clutch for driving fasteners.
- Cordless Impact Driver: it is a perfect tool for screwdriving activities, it is more compact and lighter and its 24 torque clutch makes it perfect for such use.
- Cordless Screwdriver: This lightweight electrical machine is used for driving smaller screws. It lasts for a long period of time without exhaustion and can be accessed even in small spaces.
FEATURES OF A CORDLESS DRILL
The power of a cordless drill is measured in battery voltage and higher voltage means the tool has more torque-spinning strength to overcome resistance. Drills today come in higher voltage which is enough power to bore big holes in floors and framing lumbers. But the trade for power is weight, a 9.6V drill weighs 3½ Ibs while an 18V weighs about 10 Ibs, the higher the power voltage the more weight the tool carries.
Unlike before when most cordless drills came with pistol grips and the handle is found behind the motor like that of a gun but today we see these drills with a T-handle, the base of the handle accommodates the battery which is centered under the bulk and weight of the motor and prevents hand slips and in heavier drills it provides a good balance.
What separates a cordless drill from a corded one is the presence of an adjustable clutch, which is located right behind the chuck. When a particular level of resistance is reached, the drill drive shaft detaches with a clicking sound. A drill requires a clutch to give control so as not to overdrive it and it also protects the motor when in use to tighten a bolt or screw a nut.
Depending on the drill, the number of separate clutch settings varies, one can really fine tune the power delivered by a drill with many clutch settings, high numbers are for large screws while low numbers are for small screws.
Drills come with varying speed limits which can be selected depending on the job, most of them have two fixed speeds; 300 rpm and 800 rpm, low speed is for driving screws while high speed is for drilling holes. It is always advisable for carpenters and repairers to choose a drill with the same two speeds and trigger that allows one to select a particular speed required.
- Batteries and Chargers
All cordless drills come with a battery charger, with recharge times ranging from 15 minutes to three hours. Depending on the location and availability of power source, some workers might require fast recharges but fast charging isn't always better because it damages batteries and causes overheating. For speedy recharging it is advisable to go for manufacturers with smart chargers equipped with feedback circuitry and temperature sensors which allow fast charging in as little as nine minutes without damaging the battery and causing overheating.

FREQUENTLY ASKED QUESTION ON CORDLESS DRILLING MACHINES (FAQs)
How long does a cordless drilling machine last?
It is normal for the battery to lose the capacity to hold a charge over time and this would depreciate the usage time of the battery, but when it comes to the lifespan of a well-managed cordless drill battery should be able to last up to 3-5 years or even more.
What Cordless Drill Should I Go For?
There is actually no need to overwork yourself in thinking about all the possible jobs that need to be done by your new tool. The type of drill to get will widely depend on the type and nature of job that you might want to carry out as seen in these three categories;
- Light maintenance and repairs
- Repairs and re-modelling
- Heavy duty construction
Depending on the type of job that needs to be carried out, you should select the handle type of the drill machine. It can be pistol-shaped or T-handle shaped. The latter is preferred for heavy-duty drilling. Also, selecting the right chuck size is essential for the perfect drilling. The tool required for the job should have optimum speed. These tools come with options of variable speeds to set according to the work required.
With all the different models of drill/drivers on the market, it’s easy to buy more tools than you really need. The solution is to buy a drill based on how you will use it. It's quite a waste of resources and time to buy tools that will only be used to hang pictures, or get a drill for less and burn it out as a result of heavy work.
What Should I Consider Before Buying A Cordless Drilling Machine?
There are various parameters to consider when buying cordless drill machines online Here are what to look out for;
- Chuck jaws: Maximum capacity on most drills is 3/8 inches. Some 14.4 and 18V drills can handle 1/2-inch-diameter bits.
- Clutch: More settings give you greater control of the depth screws are driven.
- Speed-range switch: High is for drilling; low is for driving screws. Look for the widest range between them.
- Forward/reverse switch: Should be easy to operate with your thumb and trigger finger.
- Hand grip: Texture and contour should aid your grip; try out the grip before you buy.
- Voltage: More voltage means more power but also added weight.
- Battery: Two are better than one. New NiMH batteries offer some advantages.
- Trigger: Make sure your index finger fits around it comfortably when gripping drill. Variable speed offers the greatest control.
- Keyless chuck: Hand-turn it to open and close the chuck jaws.
