2 - Combi dril - This option is designed for drilling into wood, steel or masonry.
3 - SDS Hammer drill - Can be used for drilling into wood & metal although generally regarded for drilling into masonry.

Drill Drivers

Makita BDF452RFE 18V Lithium-Ion Drill Driver
The drill driver is designed for drilling into metal and wood. This is generally a cheaper option than the combi due to having less features. In most cases the drill will have settings around the collar of the chuck, you will be able to select the drilling option or the screwdriver option depending on what job you are attempting.
Another option will be the torque settings which will adjust the strength at which the chuck will turn, for harder materials the torque can be set higher to help acheive better results.
Drill Drivers can come in cordless or corded versions.Example of a Drill Driver

Combi Drills

A similar design to the drill driver but with an extra option, the hammer mode. The hammer mode is for when drilling into masonry. It enables a small piston to continuously tap at the back of the chuck to give extra help to get through the masonry. The collar still has the torque settings but the extra option of drilling into more materials gives this drill a wider range of applications, therefore a higher price as well.

The SDS Hammer drill is designed mainly for use with masonry. With a piston design like the hammer option on the combi as standard they normally have a larger drilling capacity for this application. Our most popular cordless SDS Hammer drill is the Makita BHR202RFE with a max drilling capacity in concrete of 20mm.

BATTERY TECHNOLOGY

An important factor in cordless tools is the battery technology. The new lithium batteries now available with cordless tools make a huge difference to the run time of the machines as well as the charge time and battery life.
With a fast charger with older Ni-Cd or Ni-MH batteries you could still be looking at 30 minutes or even 60 minutes charge time, the Makita DC18RA charger for lithium batteries has a charge time of 22 minutes from flat. Add this to the fact that you could gat up to 2000 more cycles from a lithium battery compared to the older type and you can see why most professionals these days opt for lithium technology.

SELECTION PROCESS

The best way of choosing the correct drill is to start with the basics. Decide on the application that you need it for, if your not going to need to drill into masonry then you don’t need a combi or SDS drill. Although if you are going to need to drill into masonry then a drill driver is not the tool for you. The application is usually the main factor in deciding on the correct tool for the job!
