Makita Usa Inc 9557PB 4.5 Inch Angle Grinder Ac/dc

Product Description

The MAKITA USA INC 9557PB is a 4.5-inch angle grinder built for heavy professional grinding applications. It runs on a 7.5-amp motor and accepts both AC and DC power sources, making it a practical choice for job sites where power supply varies. The labyrinth construction seals the motor and bearings from dust, debris, and contamination, extending service life in demanding environments. The rotatable gear housing adjusts every 90 degrees, giving the operator flexibility when working in tight or awkward positions. Licensed electricians, general contractors, and metal fabricators are the primary installers and users of this tool.

The 9557PB is suited for residential and commercial job sites where grinding, cutting, and surface prep work require a compact, portable tool. The extra-large paddle switch allows easy on/off control even when wearing heavy work gloves. The small-circumference barrel grip reduces operator fatigue during extended use. The lock-on/off feature supports continuous operation without holding the trigger, which is useful for prolonged grinding runs. The AC/DC compatibility makes it adaptable for use with generators and alternative power sources commonly found on remote or active construction sites.
