Avenger 550 Floor Grinder

Avenger 550 Concrete Surface Grinder is designed for the highest production rate

The Avenger 550 is the perfect mid size machine with huge 7.5 Hp capacity. The Avenger 550 is single phase power input but a Three Phase machine on board for better reliablity, but you can power it with Single Phase 110 or 220 volt power input, so you can use it at a home or small business location. Just plug it into a stove or dryer outlet. We also have any other 3 phase voltage you might need or International Voltages are available.

All Gear Design
The 550 is all gear design with drive to each of the three flex heads as well as power to the drum for the highest production rate in its size.

Magnetic Instant-Change Tool System.
The Avenger 550 comes with the Magnetic Instant-change tool mounting system. All you will need to purchase is the diamond tools you will need for your particular project. The system can mount scrapper tools ,regular metal trapezoid tools, and velcro mount tools. 

Water and Dust Resistant Electronics 
The Motor controller on all Avenger machines are indoor and outdoor rated for harsh environments with water and dust protection. You get maximum cooling when it is hot because the cooling fins are always open to the air not sealed in a cabinet, and no entry of dust into the electronics cavity. USA MADE  

Control Head
The Avenger 550 has all the features of much larger machines, such as forward and reverse directions on the grinding heads. This allows you to run directional tools such as scrapper tools to remove epoxy and glue. Most diamond tools do not have a direction so you can run those either way. The 460 also has variable speed to grind rough floors by slowing down the grinding heads to keep them from bouncing which will stop them from cutting. By speeding up the grinding heads you can polish and burnish the floor with the proper tooling. Variable speed also allows you to work on marble and granite floors.

Ratcheting Handle
You can instantly adjust the handle to be more comfortable, or to tip the machine over or to store the handle outr of the way. 
One squeeze of the lever and move is to position.
