Types of Electric Drills

There are several types of electric drills, including corded drills, battery-powered (cordless) drills, hammer drills, combination drills, rotary drills, magnetic drills, and more. All these drills are applied differently and used for different purposes.

• Corded Electric Drills

  The best thing about corded drills is that they just plug into the wall and offer a constant supply of power to the user. Because of the unlimited power, they are great for long and intensive drilling work. They are too powerful to be suitable for basic home use as they require the presence of a power outlet nearby. Corded drills are often used in professional settings and workshops.

• Cordless Electric Drills

  Cordless drills are electric drills, which, as the name suggests, can be used without cords, as they are powered using rechargeable batteries. Such drills allow easy and convenient drilling anywhere without the need to be attached to a power outlet, and their battery operation makes them especially useful for onsite or fieldwork. Even though battery drills are not as powerful as corded drills, technological advancements have ensured that newer models hold comparable power and longer battery life.

• Hammer Drills

  Hammer drills are not basic drills that make holes in concrete or masonry walls. They operate with a unique mechanism that combines the rotating action with a hammering motion, which allows them to break up harder materials while still being able to drill into wood and metal.

• Combination Drills

  These drills that combine the basic functions of a drill and a hammer drill are also known as rotary hammer drills. These drills have various settings, including normal drilling, hammering, and rotary drilling. These drills are very versatile and ideal for almost all kinds of tasks.

• Rotary Drills

  Rotary drills are a powerful variety of drills mainly used for heavy construction work. The difference between these drills and other drills is that these drills have a mechanic hammer function that enables them to drill and break hard materials like concrete and stone. An example is the RD-2-100 rotary drill, which drills up to 100 mm max drilling diameter.

• Magnetic Drills

  Magnetic drills, also known as mag drills, are a special type of rotary-based product that utilizes magnets to attach to a ferromagnetic workpiece. They are mainly used in the fabrication and construction industry to drill large holes in metal plates and beams. Because of the magnetic base, these drills are very stable and ideal for vertical and overhead drilling.

Applications of Electric Drills

• Home Improvement and Renovation

  Electric drill sets are the most commonly used tools in any home improvement project. From hanging shelves, curtains, and cabinets to drilling holes and assembling furniture, electric drills save time and effort with their versatility. Cordless models are especially ideal for home use as they can be used without being plugged into a power outlet.

• Construction Works

  Electric drills are one of the most crucial drills in the construction industry, whereby hammer and rotary drills are employed to drill concrete, masonry, stone, and other building materials. Electric drills help contractors and builders make precise holes for anchors, fastening structures, and other applications.

• Manufacturing Industry

  Electrical drills are commonly utilized in manufacturing sets, especially in metalworks and woodworking industries. Drills are used to create holes, attach parts, and do other operations on different materials. Variable speed and cordless drills are most preferred in this area for their flexibility and precision in many applications.

• Automotive Applications

  Electric drills are used frequently in the automotive industry to make repairs and assemble vehicles. They do such things as drilling parts, installing screws and bolts, and performing other mechanical tasks. Cordless drills with special attachments are commonly used to assist the technicians in their operations in tight spaces.

• Metal Fabrication

  In metal fabrication, magnetic drills are mostly utilized to drill accurate and sizable holes in metal sheets, plates, and structures. The magnetic base provides exceptional stability, particularly in vertical and overhead positions, which is very practical when working on large assemblies and constructions.

• Woodworking

  In woodworking, electric drills are used to create pilot holes, move fasteners, and for other joining methods, such as in the making of furniture, cabinets, and other wooden structures. Cordless drills are especially popular to crafters and carpenters for their convenience.

Electric Drill Features

• Variable Speed Control

  This is one of the important features of electric drills. This feature enables the user to adjust the drilling speed according to the application. Cordless drills have variable speed controls, ideal for different drilling methods, such as drilling into softwood and metal, fastening, and others.

• Hammer Function

  Hammer drills and rotary drills incorporate a hammering function into their drilling action to enable them to drill into concrete, masonry, and other hard substances. The electric drill set for home use is usually without the hammer function because it can never be used on hard materials.

• Torque Settings

  Torque settings are basically the amount of rotational force an electric drill can put on a fastener or drill bit. Different torque clutch settings made electric drills versatile – low torque can drive screws within a wood piece and high torque to drill through steel.

• Chuck Size and Type

  The chuck is the part of the drill that grasps or holds the drill bit or bit adapter. Usually, chuck sizes range from 10 mm to 13 mm for home electric drills and up to 16 mm for professional electric drills. There are two types of chuck – key and keyless. Key chucks require a special tool, a key, to tighten or loosen the jaws, whereas a keyless chuck tightens and loosens by hand with simple spinning. These two types of chucks have different advantages and disadvantages.

• Battery and Power Options

  Cordless electric drills are powered by rechargeable lithium-ion batteries, which usually come in varying voltages from 9 to 20 volts. Higher voltage means more power and is more suitable for heavy work. Some drills have dual battery systems that allow one battery to be charged while the other is being used. Other cordless drills have quick-release battery packs to allow fast swapping of a drained battery with a fully charged one during emergencies. Certain electric drills are powered directly by electricity, which provides continuous power without the hustle of battery charging. Corded drills are corded drills.

• Ergonomic Design

  Electric drills are designed to be held comfortably. This is more important for people who use drills for longer periods. An electric drill's weight, grip design, and trigger location are factors in its ergonomics. One of the lightest drills is carefully designed for comfort if working for long hours, and one of the heavier drills may not be after a few hours.

How to Choose an Electric Drill

Many other factors should be considered when choosing the best corded electric drill apart from the type of drill. These factors include power, speed, chuck size, battery, drill/driver ratio, price, and warranty.

• Power

  The power of the electric drill refers to how much voltage or torque it is capable of producing. Cordless drills have voltage ratings, usually between 9 and 20 volts. Higher voltage means a drill better suited for tasks like fast motor driving or even drilling. The power of corded drills are powered directly by electricity; hence, they provide consistent power without fluctuations. Torque is a measure of turning power expressed in units such as inches per pound or Nm. More torque means better drills in tougher applications.

• Speed

  Speed is measured in RPM, meaning revolutions per minute. Different drills have different speeds. Variable-speed drills can have different speeds for different applications. Drills for home use do not need to be more than 2,500 RPM. Higher-speed drills are better, especially for more precise work like drilling in metals. Hammer drills have a hammer action mechanism, which adds pulsating beats to the rotation for drilling into hard materials such as concrete.

• Chuck Size

  Chuck sizes usually range from 10 to 13 mm for most corded electric drills, and 16 mm for the more professional drills. Larger chucks mean the drill can hold drill bits of larger diameter sizes, and smaller chucks would be suitable for lighter duties. 10 mm to 13 mm chuck drill, which is the general electric drill, and 16 mm chucks are for heavy usage, such as in the working areas. Drill models have different types of chucks – standard chucks are like a key and a keyless one.

• Drill/Driver Ratio

  This is the relationship between the speeds for both drilling and driving. The ratio signifies one important aspect of drills – how fast it drives when compared to its drilling speed. The lower the ratio, the better the drill for driving operations. The higher the ratio, the better the drill for drilling operations. For home use, an ideal drill/driver ratio should be around 8:1.

• Budget

  Electric drills vary in prices. Cordless drills with brushes or corded drills are affordable, while cordless drills with brushless motors, combined drills, and other advanced features are quite expensive. So, when one is purchasing an electric drill, there is a need to set a reasonable budget based on the usage requirements.

• Warranty

  Since electric drills are expensive power tools, they often come with a warranty for a certain period, mostly a year. Extended warranties mean the drill will be covered for more time in case of breakdown or even repair defects. Typically, warranties are used to give an assurance on quality and durability. It is advised to check out the manufacturer's details regarding the warranty conditions.
