Best Hammer Drill Reviews
Expert Buying Guide on Hammer Drills
A hammer drill, also known as a roto hammer or rotary hammer, has many uses in the construction site as well as the home workshop. It works pretty much like a regular hand drill being smacked on its back side with a mallet. Providing a short and rapid hammer thrust, the tool pulverizes relatively brittle material and provides faster drilling. Many of the units featured in the best hammer drill reviews are electrically powered, but more and more models run on batteries.
A hammer drill is well suited for drilling holes in stone or masonry. It can also be used to create holes in concrete footings to pin concrete wall forms. In addition, a hammer drill can be employed to drill holes in concrete floors so you can pin wall framing.
Large rotary hammers featured in the best hammer drill reviews are typically used for repetitive drilling of large rebar holes for anchoring, or simply doweling. The device’s hammering action helps to pulverize masonry for easy removal by the flutes in the drill bit.
The top rated hammer drills 2017, which are bulkier and more expensive, are well suited or applications that required use of an unknown material, perhaps wood studs or concrete blocks. A typical example of such an application is when an electrician has to attach items, such as switch box, to either masonry walls or wood studs.
Equipped with a uniquely designed clutch, the best hammer drill 2017 not only spins the drill bit but also punches it in and out. Although the force of the bit’s blow and the actual distance it travels are very small, the hammering action is quite rapid at thousands of impacts per minute (IPM) or blows per minute (BPM). The blows may each have relatively low force, but their huge number offers adequate power to pulverize brick or concrete with the carbide wedge of the drill bit, which has spiral flutes to whisk the pulverized elements away.
Drilling a lot faster than a regular speed drill, the hammer drill bores holes through hard materials for attachment of wall plugs, concrete screws and anchor bolts.
Hammer drills usually feature a percussion or cam-action hammering system, which has two sets of toothed gears that interact mechanically with each other to execute a hammering action as the drill bit rotates. Using the hammer action alone is not possible, as the drill bit’s rotation over the cams causes the hammering action.
The advanced power machines featured in the best hammer drill reviews provide a bigger impact force through the utilization of a special technology called the electro-pneumatic hammering system. With these types of tools, the air pressure in the electro-pneumatic chamber facilitates the efficient transfer of hammering force. They allow separate use of the rotation and hammer functions, as well as a combination of both.
