This grinder also has an AC/DC switch for use with alternative power sources. The 9557PB is a versatile and powerful grinder engineered for cutting grinding and makita circular saw polishing applications. Makita’s 4-1/2” Angle Grinder combines power with comfort and motor-protection features for longer-lasting industrial performance.
Boasting a 7.5 AMP motor that delivers up to 11,000 RPM, this angle grinder packs all the power you need for cutting through slabs up to ¼”. When testing the Makita, I compared it to several other angle grinders with the same grinding wheels and cutting discs attached. Not only did this give me a solid grasp of how the Makita performs, it also showed how it stacks up against other cordless models.
There wasn’t any noticeable jump or jolt, which made maintaining my desired grip and lining up cuts quite easy. To protect the user’s hands from the spinning disc and sparks, the Makita angle grinder comes with a two-piece handguard. It also has a thumb-activated switch that locks into the “on” position for extended use.
The BL Brushless Motor eliminates carbon brushes, enabling the motor to run cooler and more efficiently for longer life. The Active Feedback-sensing Technology (AFT) turns the motor off if rotation speed suddenly slows or the wheel is forced to a stop. The 9564PC is powered by a 13 AMP motor that delivers 10,500 RPM, with soft start for smooth start-ups.
Finally, DIYers who worry about a grinder being too much of a tool to handle are ideal candidates for the Makita angle grinder. Sure, it’s a powerful machine, but the slow-start and the vibration control features make wielding it a breeze. Compared to other models, the Makita’s ergonomics and handling are spot-on. To combat the kickback caused by a larger grinding wheel, it features built-in slow-start technology to ramp up the speed slowly. Grinding wheels are quite a bit heavier than cutting discs, so I expected some kickback when I started the grinder with a grinding wheel installed. Fortunately, the Makita’s slow-start technology made starting it up with a grinding wheel feel no different than a cutting wheel.
Their proprietary zig-zag varnish also seals the armature from dust and debris for to extend the life-span of your power tool. Grinders are portable power tools used for different metal manufacturing tasks, such as cutting, grinding, deburring, finishing, and polishing. Aside from this, users can also utilize grinders to remove paint and rust, cut ceramic tiles, clean metal, sharpen tools, carve wood, and many more. They are often powered by electricity, either corded or battery-operated. When you need equipment that can withstand harsh working conditions with a quality guarantee, Makita power tools will provide you with reliable, dependable performance on any jobsite.
