Woodworkers and other professional handymen have long known that better tools give you better work results. And modern cordless drills certainly qualify to be among the better tools.
With rechargeable battery as its source of power, the cordless tool is highly popular and does not directly require a power outlet to operate. This popularity has consequently caused the appearance of other specialized tools such as hammer drill and impact driver. Here a look at what these favored tools are.
1. Impact Driver
While the hammer drill is specially good at drilling in masonry, the impact driver is specially good at driving long screws into wood. The impact driver is like a hammer drill with enormous torque. It has the impacting action always on, but it doesn't work with round-shank drill bits directly because its sole purpose is to sink screws into wood quickly and easily.
With an impact driver you can drive long screws in without the need to pre-drill holes for the screws. While the hammer drill is good for drilling in masonry, the impact driver is good for driving long screws in wood. It doesn't have a hammer setting since its impacting motion is always set.
For jobs such as building a fence of a cabinet, you need to drive tens and hundreds of long screws in succession. This is where the impact driver can do best. It can finish the job much faster than a regular cordless drill because the step of pre-drilling holes for the screws can be skipped. Sometime the impact driver is called a impact cordless drill. That's not quite accurate because it's not really used for drilling, but for driving only.
2. Hammer Drills.
Both in looks and functions a hammer drill is almost identical to a cordless drill. They both are rotary tool whose main functions are to drive fasteners and to drill holes. But the hammer drill has one extra capability that the other one doesn't have: a hammer setting that can be switched on or off. What this hammering or impacting action does is very important in masonry work.
Since cement or rock or brick is what's involved in masonry work, normal drill bit can't scrape off material and bore into it as easily as it does with wood. The result is that the bit gets dull quickly and progress is slow. This, however, can be remedied by the hammer drill. By switching on its hammer setting, it will provide chipping as well as scraping action during the drilling. Now the drilling can be done much faster, but you will still need to use masonry bit for this type of work. Naturally, the hammer setting costs a little more. But it's well worth it, particularly when you need a tool to do any kind of foundation or masonry work.
3. Cordless Drill
Cordless drill is a rotary tool that can do both drilling and driving. It is a drilling tool when it uses drill bit, and it's a driving tool when it uses a screw bit or socket bit. A more proper name for this tool should be cordless drill driver, since it's capable of doing both. Its power capability is designated by voltage, which can range from a small 4-volt all the way to a giant 24-volt. Which one is better suited to your need? That will depend on what your projects are. The less powerful one is to do simple basic tasks, and the more powerful one is to do large construction projects, like building a log cabin. The real popular one is middle of the range, a 14v or 18v for example, that can do jobs large and small equally well.
