How to Use a Hammer Drill
When you need to drill holes into solid surfaces, the hammer drill is the best tool for the job, especially when trying to make more than a few holes. The push and pull motion, along with the drilling effect, are the key features that makes a drilling hammer efficient in drilling on tough materials rapidly and easily.
Step 1 – Get the Right Measurement
Get the size for the bit to be used for the desired measurement of the hole. If you will be drilling a big hole, you may want to drill a pilot hole to maintain the accuracy of the bit without bending into the material.
Step 2 – Pick the Right Bit
Choose the right bit for the material you will be drilling. Also consider the sharpness of the bits and use carbide for an additional tougher tip.
Step 3 – Attach the Bit
Attach the bit into the hammer, ensuring the tightness of the attachment. Use a chuck to tighten it.
Step 4 – Mark the Drill Bit or Set up the Depth Stop
Measure the depth of the hole. If your hammer drill features a depth stopper, set it up to the desired depth. However, if your hammer drill does not have that feature, just wrap the bit using masking tape to mark the depth that you want to drill.
Step 5 – Plug It up
Look for the safest and nearest outlet to your project to eliminate the use of an extension cord. However, if you need one, make sure that you will be using a heavy duty cord for this type of power tool. Plug it up and then turn it to hammer setting. Make sure that you have protective goggles, ear defenders, and safety gloves ready. Wear them before beginning to drill.
Step 6 – Point It out
Place the tip of the bit on the preferred area. You need to make sure that you are precisely pointing at the right spot. Pull the trigger and then start drilling. You do not need to apply too much pressure on the drill, for it will do the job for you. Just put light pressure on the drill as it does its job.
Step 7 – Blow It away
From time to time, you will need to blow away the dust and bits of rocks from the hole. When you are done drilling, simply switch the unit to the reverse setting to pull the bit out of the hole.
There are times when a drill does not work as you intended, like when you hit a significantly tough material. When this happens all you need to do is to put a concrete nail into the hole and start hammering. This technique will help you break that tough material and then you can go back to using the hammer drill.
