Fitting the FEIN MultiMaster, this 115mm backing pad has the hook and loop system to attach the discs. Supplied with six discs: 2 x 60g, 2 x 80g and 2 x 180g. The FEIN Starlock (patented) oscillating multi-tool mounting system overcomes the disadvantages found with previous designs. Starlock sets the new standard in the oscillating multi-tool market. The design greatly improves the transmission of torque from the motor to the tip of the blade. No more wasted power, means faster working, minimised vibration, the potential for longer blades and better results. Looking rather like a crown bottle top, the raised portion of the Starlock snaps into the next generation of multi-tools, making the system truly tool-less.
