How did our predecessors ever manage without cordless power tools? In the last few years, there is a rapid development in charging time, battery life, ergonomics, and motor technology. Taking into account these enhancements, maybe it’s a good opportunity to retire your old yellow tools. With the huge selection readily available cordless tools it could be difficult to decide the most useful tools for your budget and as per requirements. However, one must serious understand their project need, usage and the extent they are ready to invest because cordless tool offers great flexibility but are low on turning power/torque.
Just a thought of a cordless variety of tools gives rise to many possibilities of their uses. Cordless tools are not just handy but also highly durable with improved batteries to enhance work time per recharge. They now score over the corded tools which excelled due to the continuous power supply for uninterrupted operations. Lithium-ion technology currently powers almost all electronic devices and mobile power tools. Efforts are underway to achieve higher power efficiency, longer life cycle, improve safety & sustainability, and reliability. The energy density of a lithium-ion battery is typically more than nickel-cadmium based battery systems. A lithium-ion battery does not discharge like a nickel-cadmium battery towards the end of its cycle. The charging time of a lithium-ion battery, which earlier was in a couple of hours has been significantly reduced to 20 -30 minutes and is expected to come down further. Lithium-ion batteries marketed by many manufacturers are approximately been 20 per cent more powerful and deliver 40 per cent longer run time than those of lithium batteries sold four years ago.
Some other noteworthy improvements those have been affected by advancement in electronics to make cordless tools more popular among the workers, include more efficient brush less DC motors as there are no electrical and frictional losses. A DC brush less motor has a static armature with permanent magnets those rotate about and an electronic controller substitutes for the brushes. The design gives more torque to weight ratio, for higher output, reliability and long life. Electronics also protect power tools from overload and thermal burn-up faced by cordless tools of yesteryear. Cordless tools now have a battery gauge to know about the amount of battery power available to a user when he picks up a tool.
Cordless tools have brought a new-look to the work space. Earlier, many cords cluttering the workplace and pneumatic lines hanging from the ceiling in bunches above was a common sight. Much has changed now, with cordless tools line up by the recharging bay, you can see the workers performing their jobs without being tethered to anything. The workers are free to move about doing their work without any inference of cords or compressed air lines attached necessarily with a compressor running to feed those. The battery of cordless tools is encased in the handle in a highly compact design. Though it makes the handle a bit bulkier, a user of cordless tools enjoys cleaner and hazard free work atmosphere.
The metal fabrication jobs are more complex than it was a decade ago. Many manufacturing and fabrication operations can be achieved just because the cordless tools are there. The portability of such devices just opens a new arena in metal fabrication to face new emerging challenges. By cutting the cord, you are free to take your tools anywhere you desire. You get a large variety of sizes and power in cordless fasting tools, like drill drivers, impact wrenches, and hammer drills, that provide a great convenience to handle an outside installation job in just a few minutes. An array of cordless tools includes cutters, grinders polishers, paint sprayers for value-added field services.
Cordless tools are becoming more attractive to DIYers, as well as, assembly line workers as these devices are lightweight, compact, powerful, and have relatively better run-time. These cordless tools are now available in various sizes and capacities to perform according to needs of a job. These devices are becoming standard implements for different trades by replacing corded and pneumatic tools. With the technology of cordless tools still improving with the inclusion of newer technologies, it is possible that many new devices would be added to the existing
