Where to Use a Cordless Grinder and Where Not?

We’ll discuss how and where to use a battery-powered cordless drill driver. This is one of the must-haves in a DIY home improvement projects because of its several benefits. These include ease of handling, portable use, and wide range of applications.


Where Do You Use a Battery-powered Cordless Drill Driver?

Most DIY enthusiasts use a cordless drill driver in their home improvement projects. This is because the power tool can handle the following jobs:

  • Repetitive turning of screws, drilling of holes, and driving of fasteners. With a power tool, sore hand and arm muscles after several jobs can be avoided.
  • Jobs on harder materials like metal, bricks, concrete and masonry. With it, the drilling and driving results are easier, faster and cleaner, too.
  • Jobs on delicate materials like glass and porcelain. With it, the material’s integrity can be preserved, thanks to clean holes.

Indeed, a cordless drill driver will work best in jobs where manual drills cannot.


What are Its Parts?

But before using a cordless drill driver, you must first know its parts and their uses. You will likely use it in a safe, effective and efficient manner with such knowledge.

The most common parts are:

  • Forward/reverse control is a sliding switch with an arrow indicating the drill’s direction.
  • Speed switch sets the speed for the job. Low speed equals high torque and high speed means low torque. For this reason, the speed should correspond with the job at hand.
  • Clutch setting ranges from 1 to 10 in most drills. Choosing a clutch setting means selecting a torque range. The higher the torque, the larger the fastener for driving can be.
  • hand-o-right
    Drill and hammer drill settings are identified by drill and hammer icons. These can be used for various jobs but not for driving fasteners and screws.
  • hand-o-right
    Keyless chuck adjustment usually come with hammer drills. These have removable handles that offers more leverage and control. The result: More force can be applied when driving or drilling into cement, brick and masonry.
  • hand-o-right
    Charge indicator provides information about the charge left on the battery pack. Check it before drilling to ensure continuous work.

If you’re new to a cordless drill, you should read the instructions manual first. You can familiarize yourself with its parts and features for safe and effective use.

Drilling Preparations and Proper

Now that you know the parts, you can start drilling with the cordless drill driver. Since you’re working with a power tool, safety is always a top priority.

First, wear the right personal protective equipment. You should wear safe clothing – no baggy clothes and dangling jewelry. You must also wear protection for your eyes (safety goggles) as well as dust mask and ear buds, if necessary.

Second, choose the correct drill bit. You can suffer from injuries when using the incorrect bit for the material since either one can break. Your eyes, for example, can be injured by the flying debris from the material.

Tip: Choosing the right bit when drilling a hole for a screw is easy. Hold the screw behind the bit. The bit may hide the screw shaft from view but its threads are still visible on both sides.

Third, with the cordless drill turned off, fit the bit into the chuck.

  • Loosen the chuck using a chuck key and insert the bit into the opening. Tighten the chuck again.
  • Check that the bit is secure and straight in the chuck. Remove the chuck key before turning on the drill.

Fourth, turn on the drill with the bit facing up and away from your face. Watch the bit as it spins. Check that it doesn’t wobble from side to side, which means that it’s securely attached.

Fifth, secure the work piece. You can clamp it down, use a vise, or place it on top of scrap plywood depending on its size. The goal here is to keep the work piece as steady as possible and, thus, ensure cleaner results.

You should never hold down a work piece with one hand while you’re drilling with the other hand. You can injure yourself with the power drill since it can slip from your hands.

Sixth, start drilling. You should have an easier time drilling with a cordless drill driver than with a manual drill. But for the best results, you should keep these practical tips in mind.

  • Drill a shallow pilot hole using a smaller bit. You can switch to the right-sized bit to finish the job. You may also use masking tape in marking the place for drilling in ceramic and glass.
  • Drill using a steady pressure on the drill. You should hold the drill as steady as possible.
  • Adjust the clutch to change the torque. The higher the clutch setting, the greater the rotational force applied by the drill.
  • You should increase the torque if you’re having trouble drilling through the material. You must lower it when the screws are being buried too deeply.
  • hand-o-right
    Start at a low speed and increase it depending on the type of material being drilled. You must avoid overheating the bit by letting it rest for a few seconds at a time.
  • hand-o-right
    Avoid forcing a jammed bit through the material. You must first turn off the drill, separate the bit from the check, and remove the jammed bit from the material. Your manual tools will come in handy here.

You must let the drill do its job instead of pressing too hard on it. Light force is all that’s necessary – and if you’re pushing too hard, you chose the wrong bit.

Final Words

A battery-powered cordless drill driver is a must-have power tool for DIY enthusiasts. You can choose from dozens of brands and models depending on your budget and preferences.

When you have the right cordless drill driver, you can use it for your home improvement projects. Just be sure to respect its power in drilling holes through materials including your own skin.
