A drill is a hand tool that allows for quick drilling and screwing in both professional repair and design work, as well as amateur projects. Although its use may seem simple and easy, it is considered a delicate hand tool. Like any product, drills come in different types suited for various functions and uses.
What types of drills are there?
Drills are divided into 4 types based on their purpose and technical specifications: impact, non-impact, cordless (battery-powered), and corded.
Impact drill: Used on hard surfaces such as concrete and walls. Operates with a high noise level. Some models are a bit heavy.
Non-impact drill: Ideal for drilling and expanding holes in relatively soft surfaces like wood, metal, and plastic. You can choose these types of drills for repairs, hobbies, and various handyman jobs.
Corded drill: Drills that require high electrical energy to operate fall into this category.
Cordless (battery-powered) drill: You can comfortably use these types of drills anywhere without needing electricity.
Pay attention to these technical specifications when buying a drill
Sometimes, choosing a drill that meets your needs may not be enough to achieve effective results in your work. Therefore, it is important to pay attention to certain technical characteristics of the device during selection.
Volt: In cordless (battery-powered) drills, the device's power is measured in volts. The higher the voltage, the higher the drilling power. A 10-volt cordless (battery-powered) drill is sufficient for household use.
Watt: In corded drills, this power is indicated in watts. For household use, a selection between 500-800 W can be made. If polishing work is also to be done, products above 900 W may be preferred.
Ampere: The battery life in a cordless (battery-powered) drill is indicated by amperes. The higher the ampere value, the longer you can perform drilling work after charging.
Rotation speed: Drills that can perform 1300 revolutions per minute are suitable for household use. If drilling and boring work is to be done on surfaces like wood and metal, it is advisable to prefer devices with 3800 revolutions.
Chuck type: There are two types: keyed and keyless. Keyed models require a key to change the drill bit. If there is no key, it is not possible to change the drill bit. In keyless drill types, you do not need any key to change the bit. Therefore, it is a fact that keyless models are more practical.
