Cordless Impact Wrench Designs and Information

What is a Cordless Impact Wrench?

A cordless impact wrench is most usually a battery powered tool designed to tighten a nut or other fixing, although other varieties do exist. An impact wrench works by using a motor to spin a mass inside the tool called a hammer. The hammer stores energy which is rapidly transferred to the drive shaft of the tool, which is called the anvil. The power transfer occurs very fast and is deliberately intermittent. Peak torque can be very high, but as this transfer process only occurs for a short period of time very little of the energy makes its way back to the tools operator.

What Designs are Available?

The usual design for a light industrial cordless impact wrench is very similar to that used in automotive designs. That is to say that it is a small torque gun style of product. The difference between a battery powered tool and one powered by compressed air comes from the fact that the power comes from a batter inserted into the base of the handle, rather than a compressed air line.

These pistol style impact wrenches are the more powerful of the cordless designs available, but for jobs where access is limited they can be too bulky to use and so another format is required.

Angle head cordless impact wrenches are used where there is a desire for mobility and increased flexibility of use. A typical tool in this class can offer a number of head positions, not just 90 degrees and so can be used in a variety of positions as demanded by the work environment.

What are the Advantages of a Cordless Impact Wrench?

Cordless power tools are generally less powerful that their corded cousins, there is no denying it, but the gain in flexibility of use is great. If work is to occur at a distance from a power source then a cordless tool is a huge help as all that is required is a few batteries and work can continue with minimal disruption.

Cordless impact wrenches are also safer in the workplace as they leave no dangling cables to trip over.

Angle head tools are designed for ease of use in tight working environments and generally come with their own LED lights as natural light is often restricted in these cramped environments. While these tools lack the power of more conventional pistol grip designs they do have exception reach due to their elongated design and narrow heads. The can be excellent additions to an automotive workshop for this reason alone.

While cordless impact wrenches will never replace heavier industrial units in terms of power there is no doubt that they do offer increased flexibility of working. Surely any workplace that values safety of the workforce should consider replacing old cabled tools with a safer alternative that is a cordless impact wrench?

Diamond Earrings and Other Fine Jewelry

Diamond rings are the most common form of diamond jewelry, but diamond earrings, bracelets and necklaces are also quite popular. In fact, diamond jewelry has been around since the days of the Roman Empire, although it took almost 1500 years before diamond jewelers had figured out how to cut diamonds into attractive shapes that displayed their "fire," or shine and brilliance. Diamond earrings are but one way that people adorn themselves with this mystical, precious gem.

A Fascinating History

Chances are that the first diamond jewelry was from India. The tremendous geologic forces required to form diamonds exists mainly in regions of the world where one tectonic plate slams into another; the Himalayas, where the Indian subcontinent plows into Central Asia, is one such place. Loose diamonds from deep underneath these mountains have been known to appear in the rivers that flow south and westward from the Himalayas: the Ganges, the Brahmaputra and the Irriwaddy have all been sources of these rough, octagonal crystals.

Before diamond jewelers had learned the art of precision cutting, diamond earrings were not particularly beautiful; rough and dull-looking, they were nonetheless prized for their hardness.

One early example of diamond jewelry in the West was actually a crown made for a Hungarian princess well over 1000 years ago. One of the first diamond wedding ring was the one given to Marie of Burgundy on the occasion of her wedding to Archduke Maximilian I of Austria in 1477. It was not until over fifty years later however during the reign of Henry VIII of England that diamond cutting had reached a level that was suitable for jewelry such as diamond earrings.

Dull and Lifeless

If you had been buying diamonds back then, you'd have been disappointed; those early cuts did not show the kind of brilliance that we see in fine diamond jewelry today. It was not until the 1800s that art of diamond cutting had reached a level of refinement that allowed the gem's real beauty to shine through the way it does in contemporary diamond jewelry.

Fiery and Brilliant

Today, there are many different cuts to choose from when buying diamonds . Round cuts and square cuts both have characteristics in their favor, but a reliably new cut, called the "princess," has been gaining in popularity over the past thirty years or so. This particular cut combines the best features of round and square cuts, and causes the least wastage of all cutting methods – so the gem retains much more of its original weight. All three cuts however will make for highly attractive and valuable diamond earrings .
