What is a Cordless Drill
In this review, we will consider the cordless drills as they are the most sought-after helpers at home or on the construction site. Such drills are very flexible and feature all the main functions of the corded drills. Mobility is the main difference of a cordless drill. The cordless drill is heavier than the corded analog, yet it is more convenient.
If you have to work for a long time and perform the hard tasks, you need the powerful mains operated tool. So, we advise you to give a glance at hammer drills and consider buying one of demolition hammers.
What Features to Compare
Torque is the first thing that’s got to be considered before purchasing. This is the torque that determines the force which the drill will use to rotate. The cordless drills with bigger torque are more versatile and suitable for multiple jobs – they can screw / unscrew the fasteners and drill the holes in dense materials of various thickness. Rotations per minute is another essential parameter to look at. The higher this number is, the more powerful the drill will be. 500 RPM would be definitely enough for simple works like screwing while drilling would require at least 1000 RPM. Chuck size and drill speed are the main parameters that determine the diameter of a drilling hole. Note that the material also matters. Drilling into wood compared to drilling into a denser material will always result in bigger drilling holes.
To ensure long-term operation, the drill needs to have a high-performance battery. Usually, the battery life is predetermined by a few factors - the material the drill is used for and work duration. So if you often use the drill and for heavy load jobs, it may be a good idea to purchase one more battery and keep it at hand.
Every cordless drill features its own control system for various drilling needs. A trigger to control the speed of drilling will ensure convenient operation while a reverse switch that changes the direction of a drill bit will let you handle most jobs around the house that require screwing and unscrewing dowels, fasteners and so on.
Choosing a cordless drill, you should also consider its features. More often than not, drills are used for long-term works, and this is where the convenience of use comes down to the size of a drill. The tool shouldn’t be too unwieldy and is expected to provide an ergonomic grip. Yet, the drill that feels too small in hand might not be good for most dense materials and long-term jobs.
The chuck of any particular cordless drill determines the size of the bit that it can work with. It also determines the grip. Thus, if you're planning to use the drill for heavy jobs, consider the drills with 1/2 chuck size.
Those consumers who’ve already done some research on the Internet could probably see that all cordless drills differ in this or that way. To find the best-suited tool for your needs, consider the additional functions of different drills. A cordless drill with hammer drilling capabilities will come in handy if you’ve got no puncher at hand. Built-in lights are great for working in dimly lit work spaces. The clutch will not let the motor burn or overheat when used on dense materials.
DEWALT 18V XR Lithium-Ion 2-Speed
You'll Like It!
We'd like to describe a cordless drill made by a well-known DEWALT. This drill serves as a screwdriver, a drill, and an impact drill. The model refers to a new XR series of tools with advanced batteries for fast and efficient work. According to our findings, reduction gear and all the components of DCD785M1 are made of metal, and this surely boosts the performance and extends the life of the drill. We'd like to emphasize the 60 Nm torque as the major benefit of this drill. It is enough for drilling through wood, polymer, metal and concrete! The drill features 2 modes for optimized performance. The first is intended for screwdriving, while the second stands for drilling and hammering. 14 positions of the torque control simplify screwing and drilling materials of different density. When you deal with self-tapping screws and bolts, unscrewing will be a child's play thanks to the forward/reverse control button. In addition, this button can lock the trigger switch, you just need to set it to the central position. Also, we like a compact keyless chuck with an automatic spindle lock. The chuck allows you to quickly remove and fix bits and drills with one hand.
Now we'd like to tell you about extra conveniences of this drill. The tool is compact and lightweight, so you can use it comfortably in restricted spaces. The drill features a convenient rubber-coated handle, hence, working for a long time won't bring you hand fatigue. The built-in LED light will illuminate the place you work at when the trigger is pressed. The drill is fitted with a convenient metal belt hook for hanging the tool. The magnetic bit holder is another pleasant function that holds drills, screws, and other attachments at hand. The drill comes with a 4Ah battery that is easy to install and remove thanks to the slide fixtures. The package includes the charger that allows you to quickly charge the drills and is compatible with all Lithium-Ion batteries of XR series. Based on the foregoing features, we'd like to say that DeWalt XR is a multipurpose drill that is able to cope with most tasks thanks to its high performance.

Makita DHR242Z 18 V 24 mm Cordless Li-ion SDS Plus Rotary
It's high time to review the battery-powered hammer drill made by Makita, the world's leading manufacturer of power tools. This drill has wide functional capabilities. DHR242Z can work in 3 modes: drilling, hammer drilling, and hammering only. The drill chuck can rotate in reverse, so the drill can be also used as a screwdriver. Despite the fact that the drill has no torque control, you can still use it to drive screws and bolts, controlling the process yourself. The quick charge chuck for SDS-plus is incredibly convenient as it takes a second to install or remove a bit or drill. If you have a set of magnetic screwdriver bits, don't worry about compatibility with the drill as you only need to buy a special SDS adaptor compatible with all the kit elements. With regard to the drill powering, DHR242Z can be equipped with any Makita battery from 1.5Ah to 5Ah. Besides, Makita has outrun the competitors by using brushless motors in its tools. So, if we compare this model with a related drill BHR202, Makita DHR242Z efficiency is higher by 30% thanks to a less power loss. Owing to such performance, this rotary hammer drill allows drilling holes in concrete up to 24 mm!
Usable and Simple
This rotary drill deserves a closer attention, so we're going to tell you about some useful features. The rubberized auxiliary handle is one of the main conveniences of this drill. This handle helps distribute the load between your hands while heavy-duty use. Moreover, the handle is equipped with the depth gauge, so you can set the desired drilling depth and make truly accurate holes in any material. The connectivity of the drill with the dust extractor (not included) is obviously nice as this lets you work free from dust and debris. The drill's safety is provided by the torque limiter that disengages the motor from the output shaft if a drill bit jams. To summarize, we can say that Makita DHR 242Z can be used for the toughest tasks at construction sites.

How to Pick the Right Drill Bit?
The right drill bit allows you to accomplish drilling properly, makes the job faster, and extends the tool life.
- A metal drill bit is a round rod with 2 spiral flutes. The edges of these flutes are machined at a specific angle which is known as a helix angle or a rake angle. Each drill bit has a marking that identifies a type of steel it is made of. HSS-drill bits are usually multi-purpose, HSS-Co drill bits feature 5% of cobalt and serve for drilling hardened steel.
- The special hard-metal drill bits with inserts of titanium, tungsten, or boron are used for the masonry drilling. Such drill bits are intended for drilling concrete and bricks and are inappropriate for other materials.
- Wood drill bits come in many types; twist drill bits are designed for making narrow and deep holes, spade bits serve for making blind holes, step drill bits are used for boring large-size holes and are highly efficient.
