Cordless drills can be divided into two categories; drill drivers and hammer drill drivers.
Cordless drill drivers are used for drilling into wood, metal and plastic, and are also great to use for general purpose screw driving (for screw driving into metal, it’s advisable to use an impact driver). The defining feature of a cordless hammer drill driver (also known simply as a cordless hammer drill) is its ability to drill through masonry.
The ‘hammer’ in their name is derived from the ‘hammer action’ they employ to drill through masonry.
The ‘hammer action’ is produced by two metal plates connected to the drill’s drive shaft that have opposing raised edges. Cordless drills feature many different components, and having a sound understanding of these plays an important part in purchasing the best cordless drill for you. The voltage of the battery that the drill requires to operate will determine the approximate power and weight of the drill. The voltage of a cordless drill is determined by the batteries that the drill is designed to accommodate.
The voltage of a battery doesn’t necessarily indicate the specific power that the tool will output.
Cordless hammer drills are not available in voltages lower than 14.4V, and are usually more robust than drill drivers. Some cordless drills will have battery indicators that show you how much fuel you have left in the battery’s tank. For more detailed information on the types of rechargeable batteries used on best cordless drills and power tools, simply click here. With a flick of this switch, the drilling direction changes to allow for forward and reverse motion (right and left motion respectively).
If flicked between forward and reverse in a neutral position, it also locks the switch to prevent accidental operation of the tool. The clutch collar is very useful for repetitive screw driving, and allows screws to rest at a particular height. The more torque settings (the numbers on the clutch collar) the drill has, the more likely it is that a correct setting will be found for the respective screw driving application. On cordless drills, the mode switch allows you to choose between screw driving, normal drilling and hammer drilling.
Motors are the main component of all power tools, and are the component that converts the electricity into motion. Some manufacturers state the output wattage that a cordless tool produces (UWO, or Unit Watts Out).
If it is both a compact and powerful cordless drill you seek, look for a model with a 4-pole motor.
Also known as a gearbox, transmissions dictate the speed range (revolutions per minute, or rpm) that a drill can operate at, and the corresponding torque (or turning force) that it can produce. Cordless drill accessories come in many different sizes, and all have a recommended speed that they have been designed to operate at. To acknowledge this fact, manufacturers will state the maximum drilling capacities that a drill is capable of drilling into various materials.
The optimum drilling capacities of drills are where they will deliver their best performance. If you would like the most powerful type of cordless drill, search for those models with a planetary transmission.
A clamshell housing is where the housing is manufactured in two plastic halves, and where these halves are fixed together around the internal components.
A jampot housing is where the internal components of the drill are inserted into the housing and then a lid (usually an alloy casing) is screwed down to seal it. Some cordless drills will have an LED light at the front of their housing that light up the material upon operation of the tool, and some may have a small magnetic pad to keep extra bits handy. The handle is the component of the drill that you hold with your dominant hand and is what you use to apply pressure to the drill.
On cordless drills, the handle is called a pistol-grip handle, and is commonly covered by rubber for user-comfort. This handle is designed to stop rotation and to provide stability for the user, and is only found on heavier duty cordless drills. The depth stop is a small plastic or metal rod that sits in the side handle, and can be set to certain lengths in front of the drill to monitor the depth of holes. This is especially useful if you are drilling holes where the drill cannot go through the material or if you need to drill holes of a certain depth.
Accessories that can be used in cordless drills are the same accessories that can be used in electric drills. When purchasing the best cordless drill for you, decide what features are most important to you (from the features above) and make sure these are included in your final purchase.
For most users, a two geared cordless drill of at least 14.4V will be capable of completing the current job at hand and most future jobs that may arise.
It is important to bear in mind that the entire cost of any power tool is not just it’s initial purchase cost.

The following tips will help to preserve the life of your cordless drill, increase your efficiency, and most importantly, keep you safe. If the cordless drill has a gear switch, always ensure it pushed fully into the required gear.
You should never change the direction of drive whilst the tool is still operating, as it is highly likely you will damage the tool’s gears. Hold the drill firmly to counter any light reaction forces when drilling or driving screws.

If the bit jams because the power tool is overloaded or it becomes wedged in your work, switch the power tool off immediately.

Its versatility, portability and ease of use make it an essential tool for both the home and the workplace.
This function enables the drill to produce rapid vibrations that chip away at masonry work whilst the chuck continues to rotate.
These plates connect when pressure is applied to the chuck, and as the chuck rotates, these plates rapidly move the drive shaft back and forth. As a general rule, the higher the voltage, the more power and speed the drill will be able to produce (simultaneously). This is dictated more by the quality and design of the tool’s internal components, especially the transmission. This is mainly because they have to house more internal components, and must also be able to deal with the vigorous forces associated with hammer drilling. This feature is found on all cordless drills, and can be very helpful if you need to remove screws, or if you need to release your drill bit after it has jammed in a hole. It is found on all cordless drills, and is activated by simply selecting a number, known as a torque setting (usually a number between 6 and 24). This means that if the application requires constant changing between screw driving and drilling (or hammer drilling) modes, the clutch collar has to be constantly twisted back and forth. These ports give simple access (with a slotted screwdriver) to the most frequently wearing component of any tool – it’s brushes.
This causes the tool to stop as soon as you release the trigger switch, and mainly prevents you from overdriving and stripping screws. This motor delivers the same amount of torque as a regular 2-pole motor of the same size but in a smaller package. If a small gear is used in the transmission, then rotary speed will be high but torque will be quite low. The best cordless drills have multiple gears, which creates a much more versatile drill that will no doubt increase efficiency and effectiveness. This enables a good choice of speed and power, but prevents consumers from using a third or fourth gear for every application, in spite of differing circumstances. To accommodate these requirements, you must have a drill that has both enough torque and enough speed to handle the accessory. Drilling capacities vary wildly across models, but a cordless drill can be capable of drilling up to 65mm diameter holes in wood, 13mm holes in steel, and 16mm holes into masonry (only on cordless hammer drills). If you halve the drill’s maximum drilling capacity, it will give you the optimum drilling size, and is the size of hole you should be most frequently drilling with that drill. It’s a debatable value to base a decision upon, as eachmanufacturer uses different methods to measure it. These are the most powerful type of transmissions and are generally found on the heavier cordless drills with very chunky housings.
Depending on the quality and purpose of the drill, these chucks can be plastic or metal, or a combination of the two, and usually have a front and rear sleeve.
This durable style of housing is generally used on the best cordless drills, and is much more effective at keeping the internal components aligned and the power tool structurally sound. A simple way to gauge the power of different models (in particular models of hammer drill drivers) is to see whether a side handle is included.
The main considerations you should make include how much power you require, the size and weight of the tool, and how often you will be using it. DIY tools are designed for home use and generally include plenty of features for a very modest price. Bear in mind that at least one of these three elements is commonly sacrificed by manufacturers to reduce the tool’s price and increase its sales. Added costs can include accessories for the tool to function, maintenance, downtime, and replacement costs. Because of this, you should always prepare yourself for a sudden reaction force when drilling. There are a limited number of online resources available for detailed information on tools, especially in Australia. Most of the company usually subs the installation and cabling work to the contractor and they will only do soldering and termination work.
I think it is reasonable price since I also get the Bosch cordless touch light with lithium-ion battery.

This guide will provide you with all the information you need to select the best cordless drill for you. Therefore, the faster the drill rotates, the faster this ‘hammer action’ is, and the faster it becomes to drill through masonry.
It is therefore quite common to find a high quality 14.4V tool that is more powerful than a low quality 18V tool. When this trigger is pressed, the drill will begin to operate, and the further you depress this trigger, the faster the drill will rotate. The numbers act as a fraction of the maximum torque possible, and when the desired torque is reached the chuck ceases to rotate. The best cordless drills on the market (and the most advanced) have brushless motors that create virtually zero maintenance. Cheaper models will only have one gear, whereas high quality models may have up to three or four. If this is done, it will generally result in the stripping of a specific gear, subsequent warranty claims, and a blemish on the manufacturer’s reputation.
These maximum drilling sizes depend on the specific model of the drill, and it is recommended that you consult these specifics before making a purchase.
Nevertheless, cordless drills are known to reach maximum fastening torques of 80 Newton-metres (Nm). If not, it is most likely a light duty model that doesn’t have enough power to warrant the use of a side handle. For me having been using Bosch power tools for so many years it is natural that I choose Bosch brand. The weight of the drill with the battery is only 1.3kg and it is lighter compare to the older model.
This helps prevent driving screws too far, snapping them off, and damaging materials as you work. Got an awesome cordless drill with nicad battery packs and don't want to throw it out?
