What are drills?

Drills are mechanized power tools that are widely used to drill holes in surfaces on one hand, and to loosen and tighten fasteners like screws and nuts on the other. They can be used to drill across a wide variety of materials, including wood, concrete, metal, and so on. 

Types of drills

Drills come in a wide range of varieties, each with different functional capabilities and features. The most common types of drills include: 

• Drill Drivers: These types of drills have two functions – they drill holes and drive screws.
• Combi Drills: These are multi-purpose combination drills with hammer action. They are used widely to drill into woods, plastics, metals, etc.
• Hammer Drills: Drills like hammer drills are responsible for maximizing the applied force during the drilling process, enabling it to drill holes in harder surfaces like concrete and masonry.
• Angle Drills: These types of drills are functionally similar to combi drills but possess 90-degree bent heads, allowing drilling through materials and driving screws in small spaces.
• Magnetic Drills: Magnetic drills are portable tools used to drill through metals. They have magnets at the base, using which the drill locks itself to the surface. 

Best practices while buying drills

With so many different types of drills available in the market, it is important that you pay special attention to some factors before buying one. The following points will help you:

• Material: It is critical to determine what type of material you are going to use your drill against. Not all types of drills are ideal for all surfaces. So, for example, if you want to drill holes specifically to metals, then magnetic drills are recommended.
• Power: Another important thing to consider is the power of the drill. If you are choosing the drill to use on hard materials like stone and masonry surfaces, then you should consider selecting drills with higher powers.
• Speed: Excessive or inadequate speed of the drill can damage surfaces. Hence, considering the speed is essential. While the speed of drills depends on individual tools, you can make sure that the drill you are choosing has adaptable speed with electronic speed control.
