7.5A 4.5in, Slide Switch Angle Grinder
This the perfect, general-purpose, go-to angle grinder. I've had more than one millwright tell me this model number ranks in their top three favorites. I've only used it for simple jobs like smoothing concrete, cutting rebar & threaded rod, taking off rust, and etc. The price is hard to beat considering the quality that came with this tool.

9557NB-R
This comment is a little premature. I have only used this grinder for some small concrete finishing jobs and cutting threaded rod. However, I am very pleased with the precision of the moving parts. Judging by the vibration, noise, and how quickly the motor accelerates, I'd say this unit is up there with Milwaukee's and Metabo's similar offerings. Again, I haven't ran it under hard load for months - time will tell. My other Makita tools have taken much abuse and keep going. I'm confident this angle grinder will serve me as well.

Makita... A clear example of quality
My power tool provider of choice is Makita. I have owned Makita tools for over thirty years. My very first Makita tool was a reciprocating saw that I bought used. I still have it and it's going strong!

The recondition guys did a great job on this grinder. It looks brand new and runs perfectly. Thanks

Great general use grinder at a good price
This grinder isn't significantly more expensive than the cheaper ones available elsewhere, but the quality is significantly higher. Highly recommended for general purpose cutting and grinding.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.

Warranty Information

Makita Standard Warranty

The Makita Standard Warranty applies to both new and factory-reconditioned Makita tools. Every Makita tool is thoroughly inspected and tested before leaving the factory. If you are not satisfied with any Makita tool within 30 days of purchase, return it and Makita will provide a replacement or refund. Each Makita tool is warranted to be free of defects from workmanship and materials for the period of ONE YEAR from the date of original purchase. Should any trouble develop during this one-year period, return the COMPLETE tool, freight prepaid, to one of Makita's Factory or Authorized Service Centers.

Each NEW Makita Lithiumā€Ion Power Tool, Battery and Charger is warranted to be free of defects from workmanship and materials for the period of THREE YEARS from the date of original purchase

If inspection shows the trouble is caused by defective workmanship or material, Makita will repair (or at its option, replace without charge).

This Warranty does not apply where:
  • Repairs have been made or attempted by others
  • Repairs are required because of normal wear and tear
  • The tool has been abused, misused or improperly maintained
  • Alterations have been made to the tool
In no event shall Makita be liable for any indirect, incidental or consequential damages from the sale or use of the product. This disclaimer applies to both during and after the term of this warranty. Makita disclaims liability for any implied warranties, including implied warranties of "merchantability" and "fitness" for a specific purpose, after the one-year term of this warranty. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.
