Cordless Screwdriver A cordless screwdriver is one that uses an electric motor to turn a screw-bit. Its most significant benefit is that it provides greater torque than standard screwdrivers. Since a screw must penetrate many layers of hard material to anchor properly, such torque assumes great importance. It also proves invaluable to pull out rusted or damaged screws during deconstruction. Since a cordless screwdriver is motor-driven, it requires minimal effort on the part of the user. Even in the most confined spaces, it drives the screw in safely without causing undue hand stress. The motor of the cordless screwdriver sources power from either NiCd or rechargeable Li-Ion batteries. Both batteries are powerful, sturdy and reliable. Newer batteries in the market charge very quickly and hold out for much longer than their predecessors. Advancement in technology has ensured that both motors and batteries of cordless screwdrivers are compact and lightweight without compromising on efficiency. Cordless screwdrivers are available in a range of shapes and sizes to suit particular needs. While smaller ones resemble pneumatic screwdrivers, heavy-duty ones look like power drills and allow customization of torque, speed and direction settings. Some even comprise laser lights or LED screens to view the task better. Cordless screwdrivers save both time and labor and are ideal for woodworkers, craftsmen and do-it-yourselfers. Torx Screwdriver As its name suggests, a Torx screwdriver is used to drive in Torx screw heads. Its greatest benefit is that it increases manufacturing efficiency by preventing cam-out. Until a particular torque is reached, the screw does not slip out of the fastener. This reduces chances of damage to the screw head, the driver tip as well as the Torx screwdriver. Also, only the correct driver fits into a corresponding screw head. Both these features increase the longevity of the tool. In addition, a Torx screwdriver reduces time, effort and cost spent in tooling, resulting in cheaper products for the end consumer. Torx screwdrivers are commonly used in the manufacture of automobiles, computer systems and consumer electronics. Hex Bit A hex bit socket is a special tool that fits into a pneumatic or electronic screwdriver or drill. It is usually two-sided, with a driver on one side and a socket on the other. Both these ends work with six-sided fasteners. The driver of a hex bit socket is used to easily drive screws with hexagonal holes in or out of resistant material. The socket side is designed to receive a nut or other similar six-sided hardware. Since the socket makes contact on all six sides, the nut loosens or tightens according to the direction of torque applied. Hex bit sockets are available in a range of sizes corresponding to standard sizes of the particular hardware they are meant for. They are also sold in kits of three to twenty pieces in differing sizes.
