Drills

Drills are one of the most versatile power tools available and can be a handy addition to any DIYer’s tool box. There are numerous configurations and sizes to choose from depending on your project, but you if you need a place to start, a basic 3/8 inch model should be a good choice.

Most people know that drills can be used to create holes in various materials, but a few other functions they can be adept at are acting as screwdrivers, grinders, polishers, sanders, wrenches, and paint stirrers it all depends on the attachments used and there are plenty to choose from.

Types of Drills

Even though there may be many sizes and shapes, most drills have very similar designs – when you pull a trigger, the end of the power tool where the bit is attached begins to rotate. The end that rotates is called the chuck and once you have installed a bit or attachment, the chuck can be tightened down to hold it in place – older models needed a key for this process, but most modern drills only require hand tightening. This makes it very easy to change drill bit sizes quickly and eliminates time wasted by searching for an elusive chuck key.

Electric drills are sized by amps and cordless drills are measured in volts – the more amps or volts your drill has, the more power it’s capable of providing. Drills at the low end of the price spectrum are often limited in power and can only operate at one speed, but you have more options with mid-range and upper end models. Drills in these categories often allow you to adjust the speed of the chuck rotations by how far the trigger is depressed and you can often adjust the torque of the motor to suit your job as well. Most of these types of drills also have a reverse switch to change the direction of the chuck rotation. A few common drills types that might come in handy for your home improvement projects:

  • ¼ inch drill – if you want a complete drill collection, you might want to add one of these models to your workshop, but they’re very limited in their uses.
  • 3/8 inch drill – this universal model should be ideal for most household projects. They can range from very economical to higher end models with 8 and 9 amp motors.
  • ½ inch drill – these models are like the big brothers to the 3/8 inch drills. They feature a little more power and torque and are good for larger jobs that might stress a smaller model. They can also handle larger bits and attachments due to their wider opening chucks.
  • Hammer drills – if drilling through masonry or concrete is a part of your project, a hammer drill can make the job much easier. These power tools combine a hammer action with the chuck rotation to add a little muscle to your drilling tasks.
  • Angle drills – when you’re drilling in a tight space such as between floor joists, the 90 degree angle on the chuck of these drills can make the job go much faster.
  • Cordless drills – battery powered drills have come a long way in the past 20 years and are now capable of handling just about any job, but you’re still limited by battery capability. If you like the convenience of these handy power tools, it’s a good idea to have at least one spare battery charged and ready.

The biggest safety issue with using drills is eye protection – a fast moving bit can throw a minute piece of metal or wood back into your eye in a split second. Always wear safety glasses or goggles designed for that purpose when using a drill – even for the smallest jobs.
