Making A Large Hole The Easy Way

I wanted to remove the perforated fan grill on an old ATX case I’m rehabilitating. DSCF0003

First I drilled a 3/4” hole with a step bit.


Then I got out the largest Greenlee punch I have.


And my hydraulic driver. One of the best tool scores of my life, I paid $7.00 at a yard sale. Look at the price of a kit on Amazon.


Assembled through the 3/4” hole. A little easy pumping…and the punch makes the hole.


Releasing the hydraulic pump.


The hole and slug. This is a lot easier than using a hole saw.
