Types of Drills – (Guideline for Better Use Cases & Considerations)
This is a power tool that absolutely no one should be without. That’s because it has so many uses for both professional and do-it-yourself type users. It is just your average power drill that comes in both corded and cordless models and they also come in all different budget ranges too.
With a drill driver, you can do anything from driving all different types of screws to making a large variety of different size holes. These have a decent amount of torque and power in both corded and cordless versions. They are, however, not designed for all-day, heavy-duty use. Some of the other drills on our list are better suited for that.
The real beauty of these drills is their versatility. They feature quick-change chucks in most cases. That means you can be driving in screws one minute and then quickly switch over to drilling holes the next. They also have a wide assortment of different types of bits you can use with them. That makes them even more versatile.
These are also the most portable types of drills in most cases too. Even the cordless models are not that heavy. They can easily be kept in even smaller vehicles and they are also ready for use in little or no time at all. Drill drivers can also drill and set screws very accurately due to the fact they are so light and easy to control. As we mentioned, they are a must-have power tool for just about everyone.
These drills are really just a beefier and heavier version of a drill driver in most cases. As a matter of fact, many hammer drills can be used as both a drill driver and a hammer drill. You simply have to disable the hammer function on the drill to use it as a conventional drill driver. What sets them apart from drill drivers is they have more torque and their hammer function is very unique. These power drills are used primarily to drill holes into concrete, brick, and other types of masonry material.
How does their hammer function work? Like most drills, a hammer drill spins and uses torque to help drive its drill bits into a hard substance. But it also has an additional hammer stroke too. As a hammer drill chuck spins it also makes a percussion type strike that pushes the drill bit down harder several times a second. It’s this repeated percussive striking that enables a hammer drill to drill into masonry products faster and easier than with any other type of drill.
Since hammer drills are heavier than drill drivers, it’s tougher to drill precisely with them and control them. So they are not recommended for repeated precision drilling by hand.
Rotary Hammer Drill
These are a regular hammer drill’s larger and tougher cousins. They work very similarly to a regular hammer drill except they are made for non-stop, heavy-duty drilling into concrete, brick, and other masonry surfaces. Rotary hammer drills are heavy and powerful which can make them hard to control at times and not everybody can handle them.
They are the perfect choice when large holes have to be drilled repeatedly into concrete or other masonry surfaces. That’s because they have much torque and a heavy percussive strike. It’s no problem for these large drills to drill holes that are 1-inch or even bigger into concrete surfaces. With their special ‘spline’ bits, there is little chance their bit will spin in the chuck even under heavy torque conditions.
These large drills can also be used for other purposes besides just drilling holes too. You can insert a chisel bit in them and then very effectively do light demolition work or break up concrete with them.
Right Angle Drill
One thing that is very hard for most power drills to do when using them is to fit them into tight spaces. A right angle drill will help you overcome this. That’s because since its chuck is turned to the right, it does not have the same length from chuck to body that a conventional drill driver has. They are usually very lightweight in nature too because of the odd positions you will sometimes have to use them in.
These power tools are somewhat of a cross between a conventional drill driver and a cordless screwdriver. Because of the tight spaces they can get into, they are a favorite among such professionals as carpenters, mechanics, plumbers, and electricians.
There are some drawbacks to using right-angle drills. They often do not have the torque that standard drill drivers have. It can also be harder to keep the drill bit in the screw head or fastener you are trying to drive home with them. Because of this, you have to be very patient when drilling or driving fasteners with a right angle power drill.
These power drills are best used for driving in screws and other fasteners on a repeated basis. Because of the way they are made, they are also an excellent choice if you are driving in lengthy screws or fasteners too. That’s why they are becoming a popular choice for those that do such things as deck building, hanging drywall and furniture assembly. Impact drivers are very lightweight and easy to handle also.
Why do they work so well at these types of jobs? It’ because of their high torque and downward force they generate as they spin. So the operator does not have to put downward force on the bit as they drive in a screw or fastener. This not only makes putting in screws and fasteners quicker but it also makes it easier on the operators’ body.
Impact drivers differ from normal power drills in the fact that they do not have a conventional chuck setup on them. They have what is known as a collet on them. This collet setup only accepts bits with a hex-head shank and also makes it easier to change bits than with a more conventional style chuck. Hex shank bits stay firmly in the collet and do not spin when they encounter resistance when driving screws or fasteners. As a result of this, it’s much harder to strip the head of a screw when using an impact driver.
Because of the wide variety of styles and price ranges that impact drivers come in, they are now widely considered to be a must-have power tool for any professional craftsman or do-it-yourself type person.
These are not a type of drill that is used out in the field very often. They are best served as part of a modern workshop setup. That’s because these are very heavy drilling units that usually consist of a solid base, center working table, and a top control unit. Drill presses are specifically made to drill smooth and precise holes in all different types of materials.
They work great at drilling precision holes for several reasons. For one, you can attach the material you are about to drill very securely to the center working table. The drilling is also activated by means of a handle or wheel that will very slowly feed the drill bit into the material you need to drill into.
Drill presses have many other uses besides just making holes. They are also very useful for doing the following:
- Boring out existing holes to make them larger
- Making countersink holes
- Tapping threads into holes
- Air Impact Wrenches
