Freedom of Movement

Cordless drills give you all the freedom you want to move around the house, whereas with a corded drill you need to be near a power socket. This could be an issue for hard-to-reach areas or if you don’t want the hassle of extension leads. 

Power

Given that they’re plugged directly into a power source and don’t have a battery that could run low, corded drills tend to offer the most reliable power. However, some cordless drills come with two batteries, so if one runs out of power you can charge it while you work with the other. Li-ion batteries, which most of them are, are very efficient and charge quite quickly (often in under an hour).

The power of corded drills is measured in watts and ranges from around 450W for budget models to 1500W for more powerful hammer drills, which are used for drilling into masonry. Lower wattage drills are fine for drilling into plasterboard. For the average home DIY tasks, a 550W drill will do the job.

Cordless drill power is measured in volts, usually from around 12V to 20V. The higher the voltage, the more powerful it will be. More powerful drills that need 24 or 36 volts provide an extra boost of power for tougher tasks, though as the voltage goes up, so does the price. 

Batteries

The weight of the battery in a cordless drill can be off-putting for some as they can be relatively heavy, making corded drills a better choice for those who’d prefer something more lightweight. 

Some brands have multi-use batteries which can be swapped in and out of tools in the same range, saving you money – as well as being kinder to the environment – as you don’t have to buy a battery for every tool. If you already have a tool like this, it might be worth considering a drill in the same range.

Price

Cordless drills tend to be more expensive than their corded counterparts due to the batteries and chargers that come with them. 

Introduction

Finding the ideal one doesn't have to be a daunting task.

In this guide, I'll walk you through everything you need to know to make an informed decision and choose the perfect cordless power drill for your needs.

Let's dive in and unlock the secrets!

 

What is a Cordless Power Drill?

A cordless power drill is a portable tool powered by rechargeable batteries, eliminating the need for a cord. It features a motor that rotates a drill bit to create holes in various materials such as wood, metal, or plastic. Cordless drills offer convenience and flexibility for both DIY enthusiasts and professionals.

 

Benefits of buying a Cordless Power Drill

Investing in the right cordless power drill can be a game-changer for homeowners. Whether you're tackling simple repairs or ambitious renovation projects, having the right tool at your disposal can save you time, effort, and frustration. From assembling furniture to drilling into tough materials, a quality cordless drill is a versatile companion that can handle a variety of tasks with ease.

 

Cordless Power Drill Features

Cordless power drills are equipped with various features, each serving a specific function to enhance performance and usability. Understanding these features is essential for making an informed purchasing decision. Here's a breakdown of the key features found in most drills:

 

Power

Power is measured in battery voltage. This metric directly correlates with the tool's torque, its ability to overcome resistance. Over the past decade, top-tier voltage has surged from 9.6 to 18V, presenting a spectrum of options ranging from 6 to 18V. Contemporary high-voltage drills boast formidable power, capable of effortlessly penetrating framing lumber and flooring. Nevertheless, this enhanced power comes with a trade-off: weight. A conventional 9.6V drill weighs a modest 3 1/2 lbs., whereas an 18V counterpart can tip the scales at up to 10 lbs., signifying a notable increase in bulk.

 

Handles

Handles come in two primary configurations: the pistol grip and the T-handle. Historically, pistol grips dominated the scene, with the handle positioned behind the motor, akin to a gun's handle. However, contemporary cordless models predominantly feature the T-handle design.

The base of the handle widens to prevent hand slippage and accommodate the battery. This placement ensures the battery's weight is centralized beneath the motor, enhancing overall balance, particularly in heavier drills.

Moreover, T-handle drills offer added maneuverability in tight spaces, as the hand is positioned centrally on the drill. Conversely, for tasks requiring robust drilling and driving force, the pistol grip shines, enabling pressure application closer to the bit, thereby exerting greater force on the work piece.

 

Torque Settings (AKA the Clutch)

The clutch serves as a distinguishing feature setting apart cordless drills/drivers. Situated just behind the chuck, this mechanism disengages the drive shaft upon encountering a predetermined resistance, emitting a distinctive clicking sound.

This action allows the motor to continue running while halting the rotation of the screwdriver bit.

The clutch provides users with precise control, preventing the stripping or overdriving of screws once they're snugly in place. Additionally, it safeguards the motor from damage when encountering significant resistance during screw driving or bolt tightening.

The number of clutch settings varies across drills, with higher-quality models boasting a minimum of 24 settings. With such a range, users can finely adjust the power output of the drill. Lower settings cater to smaller screws, while higher settings are tailored for larger screws. Furthermore, most clutches offer a dedicated drill setting, enabling the motor to operate at full power for drilling tasks.

 

Speed/Gears

While basic models operate at a single speed, most offer two fixed speeds: 300 rpm and 800 rpm.

The lower speed setting is optimal for driving screws, whereas the higher speed setting is ideal for drilling holes.

A convenient slide switch or trigger mechanism allows users to toggle between high and low speeds, catering to various tasks.

For more intricate carpentry and repair endeavors, opt for a drill featuring the same dual-speed functionality alongside a trigger equipped with variable speed control. This enables users to adjust the speed from 0 rpm to the maximum of each range, providing greater precision and adaptability.

Furthermore, if your projects primarily involve drilling holes rather than driving screws, seek drills offering higher speeds, ideally exceeding 1,000 rpm at the upper end of the spectrum.

 

Batteries and Chargers

Nickel-metal-hydride (NiMH) batteries represent the latest breakthrough in batteries. They offer enhanced performance, being smaller yet more long-lasting compared to standard nickel-cadmium (Nicad) batteries. Moreover, NiMH batteries present a safer disposal option as they lack cadmium, a highly toxic element found in Nicads.

Leading manufacturers such as Makita, Bosch, Hitachi, and DeWalt have embraced NiMH technology, with others poised to follow suit.

Each cordless drill comes accompanied by a battery charger, featuring varying recharge times ranging from 15 minutes to three hours. However, faster charging isn't always advantageous.

While contractors may prioritize swift recharges, slower charging rates are generally acceptable for home use, especially if multiple batteries are available. Moreover, rapid charging can potentially harm batteries by generating excessive heat, unless the charger is specifically designed to mitigate this risk.

For those seeking expedited recharging, tools from Makita, Hitachi, or Panasonic offer viable solutions. Equipped with "smart" chargers featuring temperature sensors and feedback circuitry, these units safeguard batteries from damage while providing a rapid charge in as little as nine minutes.

 

Keyless Chuck

The chuck at the end of the drill tightens the bits. Adding a bit involves opening the chuck to spread the teeth wide, then tightening it by hand.

 

Depth Stop

Positioned near the drill bit, the depth stop prevents drilling beyond the desired depth. It is adjustable to accommodate different tasks.

 

Auxiliary Handle

This provides additional safety and precision during drilling. It can be attached to the left or right side according to your dexterity for better control.

 

Forward/Reverse Setting

This is a sliding switch feature that changes the direction of the drill's rotation. It is useful for backing out of bored holes or removing screws.

 

LED Work Light

Positioned above the trigger, this feature illuminates darker work areas, such as attics or basements. It’s activated when the trigger is pressed.

Belt Clip

It allows you to hang the drill from your belt, keeping it within reach for quick access and freeing your hands for other tasks.

 

Matching the Tool to the Job

Choosing the right cordless drill can be a daunting task amidst the plethora of options available. However, it's essential to match the tool to the job at hand to ensure optimal performance and value for money.

 

Light Maintenance and Repair

For tasks like installing drapery brackets or assembling furniture, a drill with one battery will suffice.

Look for a drill with two fixed speeds, variable speed options, and an adjustable clutch for drilling holes and driving screws accurately.

Models in the 6 to 7.2V range, such as the Ryobi HP61 or Black & Decker 9099KB, offer a perfect blend of power, portability, and affordability.

 

Repair and Remodeling

Projects involving building storage racks or hanging drywall require more power.

Opt for at least a 9.6V tool, or preferably a 12V drill for increased power.

Look for features like variable speed, two speed ranges, a clutch, and a T-handle for enhanced control and efficiency.

Consider professional-level models like the Hitachi FDS10DVA or Makita 6222DWLEK, which offer the necessary features for these tasks.

 

Heavy-Duty Construction

Projects such as drilling into pressure-treated wood or masonry walls demand high-voltage tools.

Invest in a minimum 12V or preferably a 14.4V model for these heavy-duty tasks.

Look for features like a 1/2-inch chuck to handle larger bits and longer-lasting NiMH batteries for extended usage.

Consider premium models like the Hitachi DS14DV, Porter-Cable 9873, or Makita 6333DWAE for pure power and reliability.
