1. Determine the Purpose of the Rotary Drill
One of the crucial factors to consider when choosing rotary drills is its intended use. Some rotary drills are suitable for light-duty drilling activities like home DIY projects and simple repair works, while others are perfect for professionals who deal with demanding drilling tasks. Therefore, before purchasing a rotary drill, determine the projects you plan to tackle with the drill. This way, you can choose a model that will efficiently serve your purposes.2. Consider the Power and Speed of the Drill
When selecting rotary drills, both power and speed are essential factors to consider. Power is measured in amps, and the higher the amp rating, the more powerful the drill. On the other hand, the speed of the drill is measured in revolutions per minute (RPM), and the higher the RPM, the faster the drill. For tougher drilling tasks, you need a high-powered rotary drill with considerable speed. However, for simple projects, a moderate-powered and moderately speedy drill are sufficient.3. Check the Chuck Type and Size
Another critical tip to consider when selecting rotary drills is the type and size of the chuck. The chuck is the part of the drill that holds the drill bits in place. Most rotary drills come with two types of chucks - keyless and keyed. Keyless chucks are easy to use and adjust, and they don't require a separate tool like a key to tighten or loosen them. On the other hand, keyed chucks require a key to tighten or loosen them, and they are suitable for heavy-duty drilling tasks. The size of the chuck determines the size of the drill bits that the rotary drill can hold. Common chuck sizes include 1/4, 3/8, and 1/2 inches. It's essential to choose a chuck size that can hold the drill bits you need for your project.4. Consider the Ergonomics of the Drill
Ergonomics plays a vital role in selecting rotary drills. When using a rotary drill, you need to be comfortable to work for extended periods. Therefore, choose a rotary drill that has a comfortable grip, is lightweight, and well balanced. The handle of the drill should also have sufficient padding to reduce vibrations and minimize the risk of hand fatigue. The drilling tool should also have minimal noise and vibrations to allow you to use it for long periods comfortably.5. Check the Cordless/ Corded Option
Rotary drills come in two power supply options - cordless and corded. Cordless drills are powered by rechargeable batteries and are suitable for tasks that require mobility. They are also portable and ideal for outdoor drilling tasks. On the other hand, corded drills are powered by electricity and have an unlimited power source. They are more powerful than cordless drills and are best for tough drilling tasks that require a constant source of power. Therefore, it's essential to determine the nature of your project to choose the appropriate power supply option for your rotary drill.6. Look for Extra Features
Some rotary drills come with additional features that make them more versatile and efficient. Some common features to look for when selecting rotary drills include:- LED lights that illuminate the project area, making it easy to see what you are drilling;
- Reverse functionality that allows you to remove screws easily;
- Clutch settings that allow users to set how much torque the drill applies to the screws, ensuring that they don't overdrive or strip the screws;
- Versatility, such as having the option to switch between rotary drilling, hammer drilling, or screwdriving modes;
- Dust collection system to keep the work area clean;
- Carrying cases, allowing you to keep your rotary drill and accessories organized and portability.
