9557NBR 115mm 840W angle grinder

The 9557NBR is a corded angle grinder manufactured by Makita. It is the successor of the 9557NB to which a soft start and anti restart protection feature has been added.

The machine is powered by a 840 watt brushed electric motor.

Exterior

The body is barrel shaped with black rubber on the back and ventilation inlets on the sides.

The middle part is Makita teal colored plastic with a black slide switch that is used to activate the machine.

The front of the machine is the gear housing and is made out of aluminium. It has ventilation outlets on top and a black spindle lock button.

There is also an indented arrow that indicates the turning direction. There are threaded holes on each side to attach the side handle.

The gear housing can be unscrewed from the body and attached in four different positions. This is mostly useful for turning the body upside down to put the slide switch on the other side.

On the bottom of the gear housing is a 14 mm spindle or 5/8" in countries where that is more common. The disc is held in place with a lock nut for which a wrench is needed to loosen and tighten it.

Safety

The 9557NBR adds a soft start and restart protection to the 9557NB. This prevents kickback when turning the machine on and prevents it from activating when the switch was is in the "on" position when the power is connected.

The body is double insulated against electric shocks and the machine comes with a wheel guard. However these safety features are found on every Makita angle grinder.
