I really don't know! I use the oregon height gauge I think its .23 thousands.
Oregon raker depth setting tools come in 25, 30, 25, 40 thousands up to about 70 thousands.
If you use this type of tool you should change the tool as the cutters wear and get shorter.
25 thou suits new cutters which typically have a gullet width of 0.25"
When the gullets reach 0.30" a 30 thou raker depth setting tool should be used.
When the gullets reach 0.35" a 35 thou raker depth setting tool should be used.
When the gullets reach 0.40" a 40 thou raker depth setting tool should be used.
etc
An easier way is to set the gullets using a digital angle finder like this.
Of course you don't need to do this every time you touch the rakers. After setting the rakers like this in my shop, in the filed I give the rakers a couple of swipes every 3-4 tanks of fuel. And I give the cutters a couple of swipes after every tank.
