The Festool 576947 RSC 18 EB 18V Brushless Reciprocating Saw is an impressive addition to your tool kit. Incredibly robust, and featuring a switch activated pendulum stroke with low level of vibrations. This powerfully fast recip saw offers a smooth start-up, expert control of the stroke rate along with dust extraction device. Lets start with some numbers 0-3000rpm no load speed, 32mm stroke length with 3mm max pendulum stroke with up to 230mm cutting depth in wood. The two-stage stroke rate limitation enables the cutting speed to be adjusted optimally to the material being sawn. A large trigger lets you control a smooth stat-up as well as speed control. For changing the blade, it is automatically ejected when the chuck is opened, so it can be replaced without the need for extra tools.. The saw blade can immediately be changed quickly and easily, without any risk from the sharp edges. The locking switch prevents the machine from being switched on unintentionally. Fastened to the scaffold hook, the reciprocating saw is optimally protected against falling, even at airy heights. The saw blade can be installed rotated by 180, enabling cuts up to the ceiling, wall or floor. If flush sawing is required, flexible saw blades are the best option. A dust extraction device included with the saw and is attached to the saw table without tools. Unpleasant fine dust and sawing chips are extracted directly at the point of origin when the extractor is connected. At the heart of this saw is the EC-TEC brushless motor that allows you to use the tool efficiently. As part of the design, the tool utilizes every bit of battery power when you need, all while reducing the need for ongoing maintenance by reducing the amount of heat generated and working more efficiently. The technology in creating a brushless motor system allows for perfect symmetry between battery power and usage ensuring you get all the power you need, when you need it.
