How to Use
Install the correct punch mandrel on the hydraulic cylinder along with the female portion of the punch die.
Drill a pilot hole large enough to clear your selected punch mandrel.
Insert the punch mandrel through your drilled hole in the panel. Install the male portion of the punch die by threading it down to the point where it is snug against the metal to be punched.
Close pump valve and pump the handle until the punch is drawn through the metal. Release the pump valve and remove the punch dies.

4 Inch hole punch kit
ABSOLUTELY a super product. You guys ROCK!!! With free shipping and a warranty that exceeds what I expected, you could NOT ask for more. MANY thanks for a tool that performs BEYOND my expectations!!!! Thanks a million!!!! Better than 5 stars!! Terry.
Worked great so far. Very pleased with product and price. Would buy again from this company. Thanks.
Good product for the money
Works great. A real time saver especially the 4" punch. Used to have to do it by hand with a wrench and manual punch. Took 15 or 20 minutes or so with a lot of effort. Now it takes less than a minute and very little effort. Definitely worth the money!
