Pretty good. Better than drilling. Wont punch
So far everything works fine. I hooked it up to the hydraulic pump that i already have on my tubing bender. I was hoping it would punch through thicker material, but maybe my hydraulic pump doesn't have enough balls to make the punch work to its full capacity. it still works fine for most everything that i do. Max thickness mine will punch a 3/4" hole through is 3/16" mild steel. Will punch a 1/2" hole in 1/4" mild steel. Overall it still saves alot of time over drilling holes.
