Understanding the Basics

What is an Electric Drill?

An electric drill is an indispensable power tool used for boring holes in various materials or fastening different materials together with screws. It is operated through a motor, which when powered, spins a replaceable drill bit to perform the tasks. Electric drills come in both corded and cordless models. Corded drills typically provide more power and unlimited run time, making them suitable for heavy-duty work, while cordless models offer convenience and manoeuvrability, making them ideal for lighter tasks and hard-to-reach areas.

Many modern electric drills offer variable speed controls, allowing the user to adjust the rotation speed of the drill bit to suit the material and task at hand. The drill bit is held in a rotating part known as the chuck, which can be loosened to replace the drill bit, then tightened to secure it.

What is a Screwdriver?

A screwdriver is a basic, manual tool that aids in the insertion and removal of screws. It consists of a handle and a long, narrow shaft that ends in a tip. This tip can be of various shapes to match the different types of screw heads, the most common ones being flat (slotted), cross (Phillips), and star-shaped (Torx). 

Screwdrivers are often used in applications that require precision and control, such as in electronics or fine woodworking. They allow for careful control of the torque applied to the screw, minimising the risk of damaging the screw or the material. Furthermore, screwdrivers are usually lightweight, portable, and require no power source, making them a staple in nearly every tool kit.

Electric Drills vs Screwdrivers - Key Differences

Although both electric drills and screwdrivers are designed to work with screws, they have fundamental differences. 

• An electric drill is primarily a high-torque, high-speed tool used for drilling holes and can be adapted to work with screws. It offers greater speed and power, hence is more suited for tasks requiring significant effort or for projects involving a large number of screws. Furthermore, with the right attachments, an electric drill can perform a variety of tasks beyond drilling and screwdriving.

• On the other hand, a screwdriver is a simple, low-speed tool specifically designed to insert and remove screws. It's perfect for tasks requiring precision and delicacy. A manual screwdriver gives you a tactile sense of how much torque you're applying, helping to avoid over-tightening and damaging screws or materials.

Thus, while there's some overlap in their functions, the choice between an electric drill and a screwdriver will largely depend on the specific requirements of your task.

Can Electric Drills Be Used as Screwdrivers?

Yes, electric drills can function as screwdrivers. However, their successful usage hinges on understanding their benefits, applying the right techniques, and using suitable attachments.

Benefits Of Using An Electric Drill As A Screwdriver

Using an electric drill as a screwdriver can save time and effort, especially in projects involving numerous screws or when working with tougher materials. Electric drills, with their variable speeds and higher torque, can drive screws faster and with less manual effort than conventional screwdrivers. 

How To Use An Electric Drill As A Screwdriver

To use an electric drill as a screwdriver, you need to fit it with a screwdriver bit that matches the screw head type. The bit is inserted into the drill’s chuck, tightened, and the drill’s direction switch is set for tightening or loosening screws. With the correct bit in place, align the drill with the screw and apply steady pressure to drive the screw into the material.

Precautions & Tips When Using an Electric Drill as a Screwdriver

Always use safety goggles to protect your eyes from dust or debris. Ensure the drill is switched off when changing bits and maintain a firm grip to control its power.

Choosing The Right Bit

The correct screwdriver bit is critical for effectively driving screws without damaging the screw or the material. Bits should match the screw head type and size, whether it's flathead, Phillips, or another type.

Speed and Pressure

Use lower speeds for greater control when starting a screw or working with delicate materials. Gradually increase speed and adjust pressure as needed once the screw is securely started. Too much speed or pressure can strip the screw head or split the material.

Other Versatile Functions Of Electric Drills

Drilling Holes

While the ability of electric drills to function as screwdrivers is a significant advantage, their primary function - drilling holes - cannot be overlooked. The drilling action is achieved through the rotation of the drill bit, which bores into materials like wood, metal, plastic, and even concrete, depending on the type of bit used. The drill's adjustable speed allows for controlled drilling, ensuring precise and clean holes.

Making Large Holes

For certain tasks, standard drill bits aren't enough. Larger holes, often needed for plumbing, electrics, or carpentry work, call for specialised attachments. Hole saws, for instance, are cylindrical attachments that can cut large-diameter holes in a variety of materials. Spade bits, also known as paddle bits, are another option for drilling larger holes, typically in wood. They have a sharp point for positioning and a flat, spade-like body to remove material. 

Sanding and Polishing

With the right attachments, electric drills can be transformed into a powerful sander or polisher. Sanding discs and flap wheels can be used to smooth out rough surfaces, whether wood or metal. Similarly, with a buffing pad or polishing bonnet attachment, you can polish surfaces to a high sheen. 

Wire Brushing

Wire brushes are another useful attachment for electric drills. These can be used for removing rust and paint, cleaning metal surfaces, or even roughening surfaces for better adhesion of paint or glue. 

Mixing

Surprisingly, electric drills can also be used for mixing duties. Attach a mixing paddle, and your drill transforms into a powerful mixer, capable of blending paint, concrete, plaster, and more.

Understanding the versatility of electric drills, especially their function as screwdrivers, can revolutionise your DIY projects. With correct usage, safety precautions, and the right bits, an electric drill can save time, and effort, and provide professional results.

Frequently Asked Questions

What Types of Screws Can I Drive with an Electric Drill?

The types of screws you can drive with an electric drill depend largely on the bit you're using. With the right bit, you can drive almost any type of screw, from flat and Phillips head to hex, Torx, and Robertson. Always ensure you are using the correct bit for the screw head to prevent damaging the screw or the bit.

Can I Damage the Screw or Material if I Use an Electric Drill Instead of a Screwdriver?

Using an electric drill as a screwdriver can potentially damage the screw or material if not done correctly. This is mainly due to the high torque and speed of electric drills. If you apply too much force or speed, you risk stripping the screw head or damaging the material around it. Always start with a low speed and increase gradually as necessary. A drill with a torque clutch is also helpful as it can be set to stop before the screw is over-tightened.

What Safety Equipment Do I Need When Using an Electric Drill as a Screwdriver?

Safety is paramount when using power tools. When using an electric drill as a screwdriver, you should wear safety goggles to protect your eyes from any flying debris. It's also a good idea to use sturdy gloves to protect your hands and improve grip. If you're working in a noisy environment or the drilling is loud, ear protection is also recommended.

Are There Specific Brands or Models That Are Better Suited for Use as a Screwdriver?

There are various electric drill models on the market that are particularly well-suited for use as a screwdriver. Some top contenders, available in the UK, include the DeWalt 18V XR Lithium-Ion 2-Speed, and Makita DHP484Z 18V Li-ion Brushless Combi Drill. These models offer features such as variable speed controls and adjustable torque settings, which are beneficial for screwdriving tasks. However, the best model for you will depend on your specific needs, including the scale and frequency of your tasks, and your budget.
