A manual impact driver is a powerful tool that you can use with one hand for fastening bolts. It operates on the same principle as a traditional electric drill, but instead of an electric motor turning the chuck, it has a spring-loaded punch that rotates the chuck.

Understanding how to use this power tool is essential for any DIY enthusiast; following these six simple steps will help you understand how to use this amazing piece of equipment.

Step 1:

The first step when using this tool is to choose the right drill bit. The drill bit will be connected to the chuck of the manual impact driver. Therefore you must find one which fits your needs. Common sizes include SAE and Metric. You can choose from either T-shank or Hex shank drill bits. 

A T-shank drill bit fits into a traditional electric drill chuck, whereas a hex shank drill bit will fit onto a manual impact driver or power screwdriver.

Step 2:

Next, the drill bit needs to be mounted onto the chuck of the impact driver. This can be done in two ways; using a set of spanners or using nuts and bolts. 

The spanners are usually more convenient for most people. However, there is nothing to say that you cannot choose to use bolts and nuts for this process – it is entirely up to you.

Step 3:

Place the drill bit into the chuck of the impact driver; this will ensure that it is held securely. Then tighten the set screw onto the chuck, which will secure the drill bit to the impact driver. 

You can now test your manual impact driver by pulling on your screw with a light force. If this fully engages in your screw, you are in luck! If not, go back to Step 2 and try again.

Step 4:

Now that your drill driver is ready to go, you can now prepare your work surface. Choose a sturdy and level surface to ensure that your impact driver can work effectively. 

Holding the handle firmly in your hand, let the chuck bite into the surface. Carefully set the bit onto the screw head and gently push down with some force; this will fully engage with the screw head.

Step 5:

This is when you will need to use some force and will be when you find out how useful your new tool is. 

Hold the chuck in place and simply push all of your weight onto this; this should fully engage it into the screw head. If it does not, simply go back to Step 4 and try again.

Step 6:

Once you have the screw fully engaged, your impact driver is ready to go. If it does not, repeat Step 3 and follow these six simple steps to complete your project.

Things to Consider When Using an Impact Driver:

Impact drivers and impact wrenches (sometimes referred to interchangeably) differ from each other in that there is a distinct difference present between the amount of force applied and the size of the torque produced. Torque is measured in ft.-lbs. and impacts can be divided into one-half inch, three-quarter inch, half-inch, and quarter inch. 1/4″ effects create an average 1,000 ft.-lbs. of torque at 2,500 rpm, while 1/2″ impacts produce 3,500 ft.-lbs. At 2,500 rpm. Three-quarter inch impacts create 1,800ft. lbs. at 2,000 rpm, and 1/2″ impacts give you 2,500 ft.-lbs. At 3,000 rpm.

To effectively use an impact driver, you must first work out the amount of torque required to drive the fastener into place. Determine whether to apply a breaker or tightened-fastening technique. Then, work out how much pressure you will need to apply (either by using the proper torque or loosening your grip). Then consider how far you want to go and whether the screw is to be driven in only so far as it takes for removal or if it is to be driven in as far as it needs to go for proper anchoring.

It is recommended that you use the most powerful impact driver you can afford. If you are driving long screws (screws with a head larger than three inches or with a self-tapping screw head), then you should choose one with enough power for this task. However, if you find an affordable average-powered one, it is still better to buy the most powerful one possible.

There are many different brands and styles of impact drivers available for your use today. You can choose from corded or cordless models, single-speed or variable-speed drivers, and top-handle models designed to fit into tight spaces easily.
