Pneumatic hammer drills combine the rotation of regular drills with a hammering action
. This gives them the ability to create holes in masonry easily. If you want to buy one of these drills, there are a few things you will need to consider. This article will give you a few tips for buying pneumatic hammer drills.
Depth Rod
You should always buy pneumatic hammer drills that have a depth rod. This rod is mounted on the side of the drill. The depth rods used on pneumatic hammer drills will let you know when you have reached your desired depth.
Speed
Another thing you need to consider when buying pneumatic hammer drills is speed. You should always get one that will allow you to change speeds. This is useful because it will allow you to adjust the speed for specific jobs. When you need to create small holes, you will need faster speeds. However, when you use pneumatic hammer drills to create larger holes, you will need to use a lower speed.
Reverse
You should always buy pneumatic hammer drills that has a reverse function. The bits used in these drills can easily get stuck in the masonry work. Pneumatic hammer drills with a reverse function will allow you to remove bits that are stuck and hard to get out.
Handle
Another thing to look for is pneumatic hammer drills with a side handle. This handle will allow you to use your other hand to hold the tool while you're drilling. This will give you more control over the drill. You should look for handles that can easily be removed. This will allow you to use the pneumatic hammer drills in tight areas.
Drive System
One of the final things you need to consider when buying pneumatic hammer drills is the drive system. There are two types of drive systems available, namely SDS and SDS max. The SDS systems will allow the bit to slide into the chuck of the tool, which will enhance the hammering action. SDS max systems are available in larger sizes and have larger shanks than SDS bits.
You should always look for one with a depth rod so you'll know when you have reached your desired depth. Also, you should look for pneumatic hammer drills that have a reverse function and a handle so you will have more control over the drill.
