Cutoff tool?

[Jim Nilsen]

Absolutely, 5amps of power, lots quieter when the compressor isn't running too, won't bog down as the air cycles at the low point, if you have the hand held cable drive it will get into harder to reach places, has adjustable rpms in 5,000 rpm increments to 30,000, has a light to see, can be used as a router,angle grinder,sander/polisher and more with the attachments, and most of all it will use 60% or less than the amount of electricity that your compressor will.

If your compressor draws 15 amps or more to start up and 10 amps when running you are using 2 to 3 times the electricity to operate a tool that doesn't care what spins it. The amount of time lost waiting for the compressor to come back up to pressure if you have a smaller one will even cost you more cause you are not working with the tool while you are using power. It cost 4 cent per cubic foot of air at 90 psi at 10cents per kilowatt hour. You can actually buy the Rototzip in a couple of months of hard use just from the savings alone from electricity savings.

I have worked in shops that have unlimited 100+psi air supplies and the die grinder still won't out do the electric tools you can buy that do the same.

Once you try it you will like it. Years ago when porting my heads I was using a friends compressor and die grainder to do the job to start, it was noisier ,I waited for it to come back up to power and it just kept bogging down. I went out and bought a Bosch electric die grinder for $125 and it was wonderful. The Bosch only had 3.5 amps of power and only one rpm of 25,000. The electric die grinder is also what you will see in most pictures of a pro porting heads. They will put the bigger die grinders on a tool balance because of the weight, with the remote cable for the Rotozip it weighs almost nothing and is easier to manuever and holds the same tools. It can also be turned into the most comfortable angle grinder/sander/polisher that you will ever hold, with variable speeds, try that with your die grinder!!

I could go on and on but I think that is enough to hopefully get the point across.

You can probably get a chance this xmas season to go to one of the box stores anf try one out on display.

One last thing to remember about Rotozips is how many different models and kits they have. I bought the Revolution with all of the stuff in the kit but th remote cable wich cost around 25$. The smaller models will not make you happy but the more powerful models will make you smile.

Air is used in most shops over electricity because of the safety factor of not having power cords that can shock the operators and the other hazards that happen when fork lifts and other machinery attck them and ruin them. Air is also sometimes more convienient to find an outlet in some shops.
