Impact drills do all kinds of things besides simply drilling holes. Discovering how impact drills work includes learning how they also perform on sanding and polishing jobs, driving screws into any number of materials and how they are utilized to act as brushes and to mix substances.
What Puts the Impact in an Impact Drill?
Supplemental pressure, operated by a manual feed, describes how impact drills work to aid in boring faster into concrete, rock, or other challenging materials. A mechanism located in the drill gearing system makes it possible, at the flip of a switch or lever, to pulsate the drill chuck and bit forward at speeds of up to 48,000 times every 60 seconds.
This special mechanism defines in a nutshell how impact drills work. The impact function of an impact drill can only be used when working with masonry, however. To avoid damage to it, the impact mechanism should always be turned to the off position when the drill is used to drill into wood, plastic, metal, or any material other than masonry.
Add-Ons Create Different Tools for Different Jobs
How impact drills work depends a lot upon what accessories you purchase to use with them. Sanding disks come available in varying grits of paper to refinish furniture, remove paint and rust, and a myriad of other uses. You can also buy a host of other attachments like wire brushes, grinding points, polishing sponges, drill-bit sharpeners, mixing tools, and more, all with uses limited only by your own imagination.
As important as learning how impact drills work is knowing the correct way to hold them. Some impact drill manufacturers include on their product what is called an auxiliary handle. This is a handle in addition to the main one that is located at the front of the drill. These auxiliary handles not only provide much greater control over the tool, but also allow for precision angle work.
Match Bits Properly
Using the correct drill bit also plays an important role in using an impact drill. When first learning how impact drills work, you may be tempted to use a slotted bit to take out a crosshead screw. This inevitably leads to ruining the head of the screw. To avoid this, always use the proper, corresponding bit.
A Model for Every Job
As a rule of thumb, the more powerful the drill, the larger diameter hole it will drill in concrete, stone, steel, and wood. It also, as stands to reason, does the job faster the more power it has available to use. Impact drill motors come in an array of sizes ranging all the way from 500 to 1200 watts in many manufacturers models.
Most companies provide information either online at manufacturers or resellers Web sites, within or on the product packaging, or at the retail store product display site to guide consumers as to which models do what.
