Now that we have covered drill bits, now can now look at the basic types of Drill that you can use with these drill bits.
First we have Hand Drills, these are not widely used today but you will find hand drills are still used by woodworking craftsmen. The standard Hand Drill with a winding handle is best used with jobber drill bits and lip and spur wood bits. The Carpenters Brace also known as the Bit and Brace is normally used for auger bits and flat wood bits. The Carpenters Brace can be used with small bits but due to its size it is normally used for larger drill bits as it’s design provides more torque but it requires more space in which to be used.
Cordless Drills have taken over in the main from hand drills and come in a variety of voltages and sizes covering a wide range of applications. You have the Cordless Drill Drivers which will drill wood, metal and plastics and can also be used as a screwdriver these are available in voltages ranging from 12V through to 18V.
Cordless Hammer Drills (also known as Combi Drills) are general use drills. Cordless Hammer Drills normally have 3 actions, standard rotary drilling, screw driver and hammer action. These are ideally suited to drilling into very hard masonry as they can not only rotate the drill bit but also provide a small hammer action to help the bit bite into the material. You will find this range of Cordless Drill is supplied in voltages from 14.4V through to 36V. The higher voltage machines are as powerful as a mains drill. These are good all round machines and unless you need the features or a more specialist unit one of these will prove to be the most useful type to own. Be sure to switch the hammer action off when drilling into delicate or brittle materials otherwise it could cause damage.
SDS Cordless Drills are designed to use SDS drill bits. Again, these drills can be as powerful as their mains powered counterparts. These are also available in voltages from 18V through 36V. An adaptor for the SDS Drill will allow it to use a non SDS drill bits. An SDS Drill will provide more twisting torque than a traditional drill due to the way the bits are held in the SDS chuck, because of this it is advised that you select an SDS Drill with a safety clutch to prevent injury to the user should the bit become stuck.
Mains powered Electric Drills are available in 110V and 240V models. The 110V drills are designed to be used with a transformer and are mainly used on building sites for safety. The standard Electric Drill is a rotary drill, which can be used to drill wood, metal and plastics. If the drill has variable torque and speed settings then it may be used as a screwdriver. In a workshop or in situations where the drill will always be used in the same place a mains powered drill is the better option as it does away with the issue of having a charged battery to hand, full power is always available. These are also available with Hammer actions with the same advantages as the cordless type mentioned above and are sometimes referred to as an Impact Drill.
An Angle Drill is a special tool, designed to get into tight spaces that a regular drill cannot. You hold it like a torch and the bit faces down at the end. While they are not able to deliver the same power as a regular drill they find lots of uses, especially when you consider that they can be easily used at arms length.
Lastly there is the specialist Diamond Core Drill. This type of drill is a rotary drill with a special clutch mechanism designed to be used with diamond core cutters. They have a high torque output but should the Diamond core bit become stuck in the material that is being cut the clutch will slip to prevent any damage to the user.
