What is a Drill?
A drill is a manual or pneumatic power tool designed to drill holes in various materials such as wood, metal, plastic, and masonry.
To perforate a material efficiently, you’ll need to use a drill suitable for the material you’re using.
What is a Drill for?
A drill is used to make holes in various materials to install shelves, fix screws, and assemble furniture, for example, among other things.
You can choose a drill that doubles as a screwdriver, which both screws and unscrews.
What Types of Drills are there?
There are several types of drills, each designed to match various needs and applications.
The main types of drills include:
- Manual drills;
- Pillar drills;
- Percussion drills;
- Cordless drills;
- Right Angle Drills;
- Straight Drills.
What is a Percussion Drill?
Also known as a hammer drill, the percussion drill is a power tool that combines the functions of a standard drill with the characteristics of a pneumatic hammer.
This tool is ideal for drilling hard materials such as concrete, masonry, brick, and stone.
What is a drill without percussion?
A non-percussion drill is suitable for drilling in lighter, non-resistant materials where hammering is not required.
What is the Difference between a Drill and a Screwdriver?
The main difference between these tools is that drills are designed to drill holes in materials, while screwdrivers are used to screw in and unscrew screws.
Both are useful in DIY and maintenance tasks, but the choice between them depends on the specific task you need to perform.
In addition, drills that have a screwing function may not be as efficient as a specific screwdriver built for the task.
What kinds of Industries or Jobs use Drills the Most?
Though they are widely used in construction and furniture assembly, they can be used in various industries, such as:
- Metal fabrication;
- Agriculture and gardening;
- Joinery and carpentry;
- Electricity and electronics;
- Automotive sector, especially in car garages.
Which Types of Drill Bits Can Be Used in a Drill?
You can use different drill bits, depending on the materials and results you want to achieve.
The main categories of drill bits include:
- Drill bits for glass/ceramic: these have a special, particularly hard tip;
- Drill bits for metal: made of carbon steel or high-speed steel with different angles;
- Cranial drill bits: suitable for fast, large-diameter drilling in wood or concrete;
- Drill bits for Stone: are spiral-shaped with deep grooves and have a tungsten carbide tip;
- Drill bits for wood: have wide side edges and sharp tips. They are subdivided into spiral, twist, and flat bits.
Which features should you Consider When Buying a Drill?
Before choosing a drill, you should think about your needs because there’s no point wasting money on a tool you will barely use.
Investing money – however small the amount – in a tool that doesn’t do exactly what you need it to do is also a waste.
As such, read on to find out the points you should take into account when selecting the right tool for you:
-
Torque
Electric drills always have more clamping force than pneumatic tools. However, the clamping force can be adjusted to meet your needs.
-
Cost
Air tools are more expensive when compared to electric power tools, both in terms of the cost of the tool itself and due to the need for an air compressor nearby, which costs a few hundred euros.
Electric drills are cheaper, but their service life is not as long as a pneumatic drill.
-
Feel
An essential factor to consider when buying a tool is the amount of time spent with the tool in your hands.
A pneumatic model is not connected to a pressure system. In contrast, a battery drill can be transported anywhere. However, it can be heavier.
-
Safety
As it is not connected to any type of battery or electric power, electric tools do not present risks with regard to electric shocks and fires.
Want some Tips on how to Maintain your Drill?
To ensure your drill remains operational and extend its service life, you should take some precautions:
- Clean it regularly and after each use with a clean, dry cloth;
- Check and lubricate moving parts regularly;
- Replace the brushes as soon as they are worn;
- Store the drill and bits properly, preferably in a tool cabinet.
Which Drills are available in the KROFtools Catalogue?
The KROFtools catalogue contains the following drill models, allowing you to improve the services provided by your Car Repair Shop:
Pneumatic Grip Drill 2000RPM – 10mm
This tool is regularly used in car garages and for retreads and should not be mistaken for an impact wrench, which is used to tighten the screws on car wheels, as they are entirely different tools.
To use it, you need compressed air – either in the form of a small compressor or an industrial system.

Angle Grip Drill 10mm
This angular model makes it easier to get to spaces that are difficult to access. As such, users should be aware of the direction in which the drill is screwing when in use.
Another factor that requires attention in this type of tool is whether the connections that require specific torque have the correct measurements. These must be checked with a power gauge following installation with an impact driver.
