As with their predecessors, new cordless power tools will feature a host of improved features and functions. Blowers feature a three-speed switch and a variable-speed trigger for greater clearing power, along with extended nozzle reach for greater range. Hammer drill/drivers, rotary hammers, and right-angle drills feature better shock and impact durability, overload protection. They also let users choose impact and rotation or rotation only in the same tool, have built-in work lights for dark work spaces, and use electronic-clutch technology that improves control of fasteners. Reciprocating saws have improved clutch design that extends tool life, a variable-speed trigger, a quick lever-action blade clamp, and remaining run time display. Cordless multi-tools feature blades and sanding pads with up to 18,000 oscillations per minute and offer tool-free blade change and a built-in work light. Band saws offer much lighter design for cutting overhead and in tight places, and they feature an adjustable shoe that allows flush cuts, an LED work light, and quick blade change with a blade-ejection button. Among the improved circular-saw features are: lighter weight; an ergonomic design for easier handling; a soft handle grip for better, easier control; and a quick-stop electronic brake. Metal saws are one-third more powerful, and they feature a compact design for better handling, an LED light on board, a reduced weight for working overhead or in tight spaces, and an improved carbide-tipped blade for burr-free cutting in many shapes. Cordless jig saws come with a blade clamp that provides faster and easier blade changes, a tool-free shoe bevel with positive stops, and a maximum 45-degree bevel with 15-degree increments. They also offer five-position orbital cutting, a molded grip, variable-speed cutting for a range of materials, and a non-marring shoe for work protection. Hex-impact drivers, impact wrenches, and high-impact wrenches offer improved features that include: a brushless four-pole frameless motor for longer life; more power and longer runtime; an impact mechanism designed for more speed and power; optimized performance through electronic communication between the tool,the battery, and the charger; and a hex quick-connect chuck.
