Makita GA4570 7.5 Amp 4-1/2 in. Corded X-LOCK Angle Grinder


The 4-1/2 in. X-LOCK Angle Grinder (GA4570) offers X-LOCK technology for quick tool-free wheel changes. A click-mount and pull release lever make changing wheels easy. The GA7060 weighs about 5 lbs. and is built with comfort and ergonomic features for extended use. It is ideal for efficiently grinding and cutting a wide range of materials including tile, concrete, pipe, conduit, and more.

The GA4570 is powered by a 7.5 Amp motor that delivers 11,000 RPM for the most demanding applications. The labyrinth construction seals and protects the motor and bearings from dust and debris for longer tool life. In addition, the armature is sealed by a protective zig-zag varnish which prevents contamination by creating a barrier under rotation. The ball bearing design and metal gear housing provide increased durability.

The GA4570 is a versatile and powerful grinder engineered for demanding applications including cutting, ferrous metal, paint and rust removal, shipyard maintenance, heavy machinery, metal polishing, general steel grinding, auto repair work, cutting brick and masonry, and restoration work. The grinder is built for welders, fabricators, plumbers, masons, electricians, automotive technicians, stone and tile workers, HVAC, and general contractors seeking a best-in-class industrial quality angle grinder.

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 Lithium‐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.
