In addition, the “tool-less” wheel guard adjustment provides easy clamping. 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 polishing applications.
For long grinds or cuts, I’d lock the switch into the “on” position and get to work. Angle Grinder has a powerful 15.0 AMP motor for high-demand applications. Active Feedback-sensing Technology (AFT®) turns the motor off if rotation of the wheel is suddenly forced to stop. The brake stops the wheel in 3 seconds or less for maximum productivity.
For increased versatility, the tool can also be powered by Makita 18V LXT Lithium-Ion Batteries with the star symbol on the battery indicating Star Protection inside. Setup is unfortunately one of the main downsides to the Makita angle grinder. Unlike some models, this grinder doesn’t come with the removable guard already attached; you’ll need to attach it yourself. While this is fairly simple with other angle grinders, I found the process to be a bit tricky with the Makita.
And in terms of setup, the guard was also a bit finicky to attach and remove. There is a spring-loaded metal clip on one side and, in my experience, it doesn’t operate like it should. It clips on while not being fully seated, which means that the plastic guard could potentially fall off while grinding. Then, with the plastic guard fully seated, it didn’t snap into place like I expected. I removed the plastic guard and proceeded using the tool with the metal one.
The gag01m1 is also equipped with makita’s extreme protection technology (xpt ™ ), a series of protective seals inside the tool. Xpt ™ is designed to improve a tool’s operation in harsh conditions by channeling water and dust from key internal components. Reinforced metal gear housing provides additional durability on the job site. Makita® 4-1/2 in angle grinder combines 7.5 a power with comfort and motor protection features for long lasting industrial performance. The 9557PB angle grinder delivers rpm with soft start for smooth start-ups.
Labyrinth construction prevents dust and contamination from entering the motor. This versatile, powerful grinder allows the user to adjust the RPM based on the material. The makita angle grinder also features variable speed control for polishing and grinding stones.
