When Shopping around for a Cordless Drill you may have noticed the various types you can buy, mainly the hammer drill, the Impact drill, and the normal everyday compact drill.
But What is the Best Type of Cordless Drill to buy?
Before we can know the best cordless drill to buy you need to know the difference between the two main types, that being your normal Compact Cordless Drill and a Cordless Hammer Drill, also known as a Hammer Driver Drill.
Normal Cordless Drills
Plain cordless drills, commonly sold as compact cordless drills are machines that rotate a ‘bit‘ (the large chunky metal bit at the end of your drill) in a circular motion. The drill provides no action apart from this turning motion and it is up to the user to provide the adequate pressure towards or away from the object that is getting drilled.
Normal Compact Drills rely on the design of the screws of drillbits grooves that latch on and pull through the material. Plain cordless drills are usually used for drilling into wood, vinyl, or softer materials.
Cordless Hammer/Driver Drills
On the other hand, hammer drills are a much more violent tool. The drill still turns a special drill bit in a circular motion but it also does an extra function, it hummers down on the bit pushing it into the material. These drills are normally used for drilling into concrete or steel material, material that a normal drill would not be able to drill through. It also requires a special drill bit that will not break with so much friction.
So Which is Best for You?
Of Course, it depends on the application, but as a general rule, it is not advisable to purchase a hammer drill unless you are experienced with a normal drill. The Violent action of a hammer drill and the power it is designed to hold means that only the steady and experienced hand will be able to get the most out of it.
That being said, a lot of Drills now come with the optional Hammer/Driver feature, and although this is never as good as purchasing an actual Hammer Drill, it can sometimes help get through those slightly rougher surfaces.
For example, The Makita BHP452HW 18-volt 1/2-inch compact cordless percussion-driver drill delivers versatility in a compact size to the job site. The BHP452HW can be run as a driver-drill or a hammer driver-drill, allowing the user to carry just one tool on the job instead of two, replacing the standard driver-drill.
Why Not Get Both Drills?
Most Major Manufacturers of Cordless Powertools are well aware that in today's world the line between professional and home handyman is very blurred. As such, there is a large range of Cordless Drill Combo Kits available so you have everything you need for drilling, hammer drilling, driving, and fastening.
