The Evolution Series CNC router gantry height from the table is 3.3". The maximum height from the bottom of the DeWalt collet from the table is 4.5". Without a tool change, you would be able to cut 1.2" into a 3.3" thick stock or cut all the way thru a 2.25" (or less) thick stock. With tool changes, you would be able to cut thru a 3.3" thick stock.

Calculations for the answer.

4.5" -3.3" = 1.2" bit available to cut

4.5" = 2.25" of bit + 2.25" thick of stock
