It often happens that the timing udarowo hammer-rotary and młotkowy used as synonyms in relation to power tools, are capable of beating and drilling, even for experienced builders. Of course, you will be sorry, thinking that these two tools are the same, but this is actually a misconception . Not only the percussion hammers and rotary hammers have a variety of tools, but are best suited for certain tasks. Before we discuss, which should be used and when, let’s start with a breakdown of how these two differ.
Inside the drill hammer comprises two convex disks, which spin when the button is pressed. When one is moving around, back and cause it to rise and fall. When she falls, hits each other, causing the bumps, known as a hammer drill is known. These ridges are very small, which in turn means that the disk does not move very far when raised and lowered. This impact driver creates a large impact force . Makes up for this, however, is speed, because it often happens that they move with a speed of 3000 revolutions per minute when operating under load and produce 40 000 or 50 000 beats per minute.
When the user removes the gap and remove the accent on the handle, the discs are separated by a clutch that stops the impact and reduce engine wear. Most of the percussion drills can be used in the drilling mode .
Rotary hammers have two pistons. One unit is an electronic crankshaft. When moving forward, creates a pressure increase inside the cylinder are two pistons. The air pressure drives the second piston, often referred to as the piston is flying forward, hitting the bit and creating a movement młotkujący. Because these two internal elements never touch the rotating hammers are more durable, and often last longer than drill bits, wrenches, even under heavy, consistent use. Unlike hammers percussion hammers udarowo-have rotary mode of the hammer, if necessary, turning them into mini-pneumatic hammers .
Percussion drills are best suited for light masonry work, such as drilling holes in bricks and blocks of concrete, but rarely needs to be used on fired me the concrete for a long time, as the engines are, as a rule, overheating, resulting in great wear and shortening their lifespan. Also better for drilling in wood and metal, which require a great speed. Because they do not have a hammer only mode, you cannot use them for work in the demo. On the other side of the coin-they can be used for drilling in more sensitive materials, in which the impact can cause damage and can serve double duty as a screwdriver.
Low speed and big force impact hammer is that it is a bad choice when we’re trying to make holes in one of the above listed materials, but they are excellent at drilling through cured concrete or stones. Can also be used for the works, demolition of buildings when the only mode of the hammer.
If the Drill bit fits, wear it

A lot of consumer products, initially came to market as the most powerful, better made version of themselves, only in order to imitate and lower during the year.

In America, of all places, impact drill popped up from the roots in the form of a Cam and became elektropneumatyczną power that she is today. It was in the late 60-ies, and impact energy increased with the growth of the weights, and the total attenuation has been lowered.
