Gents,

A little off topic - but I am getting ready to use my new 4.5" Dewalt angle grinder for the first time on my upcoming rocker repair.

I have here some type 27 depressed center cut off wheels. I also see on the store shelf I can get Type 1 straight wheels.

Is there any application difference? The manual says to use type 1 wheels for cut off operations, but I dont understand what is wrong with type 27. I love Dewalt tools, but this manual is very sparse for such a dangerous tool.

Can someone shed some light on when to use a type 27 cut off wheel, and when to use a type 1 cut off wheel?

Many thanks,
dd
