Fact #1. A lot of consumer products hit the market as the strongest, best-made version of themselves. Others hit a peak of quality and innovation later in their development. The hammer drill started out as a powerful, cam-action unit in Germany. The question as to who invented it is a little complicated. There's a long-standing feud between the companies Bosch and Fein over the origins. Either way, one of them introduced it in the early part of the 20th century. Once it reached America in the 1960s, it became the electro-pneumatic powerhouse that it is today.
Fact #2. Sometimes you'll see the terms rotary hammer and hammer drill used interchangeably. Even experienced construction workers get confused. It's quite a common misconception. Both are capable of pounding and drilling. However, they are completely different tools. Each is best suited for certain kinds of tasks.
Fact #3. Hammer drills contain a pair of ridged discs. These rotate when the trigger is depressed. As one slides past the other, the ridges cause it to rise and fall. They slam against each other as they fall. Because the ridges are very small, a hammer drill doesn't create a high impact force. It more than makes up for this in speed, though.
Fact #4. These devices are best suited to light masonry work. This can include drilling holes in bricks and concrete blocks. They should rarely be used on poured concrete for long periods. The motors tend to overheat. This causes heavy wear and shortens their lifespan. Hammer drills are also great for drilling through wood and metal.
Fact #5. Consider the nature of the particular job before choosing a hammer drill. If it requires tighter, tougher angles, you may want a more compact model. Though you'll sacrifice power, it'll save you money. These types are best suited to tackling under the sink and low-space jobs, where every inch counts.
