The design and shape of cordless power tools makes then fit into areas where corded power tools will not. In many cases, this leads to a sacrifice of turning strength from the motor. Dewalt power tools makes larger voltage cordless power tools to deliver more power for your job. Dewalt cordless power tools are the ones most often selected by professionals. Their dependability and ability to perform heavier work than most of the other lines of cordless tools is the reason for this. When doing repetitive work like hanging sheet rock, drill bits for driving the screws holding the sheet rock in place, tend to wear out and need replacement often. The quick-change heads of Dewalt power tools make this an easy task to accomplish with minimum slowing of the work being performed. Dewalt power tools offers a nice line of cordless screwdrivers and variable speed drills. The power ratings range from 7.2-volt motors up to 24-volt motors delivering the type of power you need. A variable speed drill is used to make a variety of different size holes from very tiny ones used to enable nails and screws to be driven without splitting the wood to large ones used for installing door knob assemblies. When using a variable speed drill, start your drilling slowly to allow the bit time enough to get firmly seated in the hole. This will lessen the chance of the bit jumping when higher speeds are applied which might cause you to drill something you did not want to have drilled. Dewalt power tools offer a full range of both corded and cordless tools. Their durability and easy ability to change accessories makes them highly desired for professionals. Dewalt power tools deliver in work conditions where other power tools fail. The only drawback I can see to this magnificent line of cordless tools is their weight. Having larger voltages to deliver more power means larger battery packs and larger motors as well. If you have to use one of these heavy cordless power tools all day, you will feel like you have done an intensive workout. Because this is a superior product, you can expect to pay a superior price for it as well. While you will see sales for the combo packs available in store ads, you may notice that these are the lighter weight tools. They will perform the work desired in most situation, but for the really heavy duty applications the heavy duty power tools will command a heavy duty price tag. Enabling Technology Dr. Adnan Ahmed Qureshi f53 You know you are a PC addict when you can't tear yourself away from what you're doing to watch X-Files. On the plus side, you know you can cope with your addiction if you can manage to raise yourself out of the swivel chair for long enough to set the video. Millions of people watch X-Files and even there are fan clubs on the Net. Its members call themselves X-Philes the sort of word play that only works online. Of course, with huge viewers you hardly need to go online to contact a fellow fan, but it's an example of the way in which PC technology enables you to extend your enjoyment of almost every activity - if you're willing to stretch a point and call watching TV as active. More interesting, though, is the way a PC and modem enables you to enjoy this kind of social life with people who keep different hours from you. Go back ten years and you had to be on the same schedule as the people with whom you spent your leisure time. You can hardly go out to the coffee-shop, see a show, eat dinner or go on picnic with someone unless they're physically available at same time as you. You have to be synchronized. This was easy when almost everyone worked days, knocked off at five and had weekends free. These days, the trend is towards never having completely free time. All this activity can make it hard to organize a social life - enter the Net. It's been obvious for a long time that Net enables those with specialist or unusual interests to get together intellectually, even if it's impractical for them to do it physically. Only now is clear it can enable you to get a social life - asynchronously. If someone lives just around the corner but your free time hardly ever matches up the Net enables you both to put that time when it's most convenient. You might download your friend's contribution to the relationship at breakfast and upload yours - he or she can put their time in when it suits. It works and even better, it's socially acceptable. No wonder it is now common to see e-mail addresses on stationary or given along with a phone number. Well it makes sense because these days it can be difficult to contact people by phone because they are just too busy. When the first telephone connections were offered for sale it was thought it would be no more than another high tech business tool. Its arrival meant that you could be friends, and maintain contacts with people removed from your space. The Internet enables you to do exactly the same with people who are removed from you in context to time and space. One of the most favorite phrases among those who work in the IT industry is 'enabling technology'. A word that's rapidly becoming just as well used is 'compelling'. Of course a technology can't be compelling until it's been fully developed and there's no guarantee that an enabling technology will become compelling. All of sudden people who wouldn't have dreamed of owing a PC are rushing out and buying latest kit complete with gadgets you can possibly imagine. Having discovered the wonders of PC communications they're no doubt going to be compelled to find out what else this enabling technology can do for them. Yep, adding a net address to those other important possessions - your car and your camcorder means you can now sift your whole life through time and space. You can't get much enabled than that, can you? About the AuthorDr. Adnan Ahmed Qureshi holds a Ph.D. in IT with specialization in the induction of information technology in developing countries.
