This hole cutter is easy to operate and carry, saves effort during use, which will not damage the processing surface and is not restricted by site or location.
First, open an 11.5mm guide hole, screw in the draw stud in the hole opener, put down the lower die, iron plate, and upper die in sequence, and finally press and open the hole.
It can only be used on metal plates below 4mm; please do not use it without load to avoid high pressure oil pipes bursting due to excessive pressure.
Hydraulic hole opener is perfect for drilling holes in a wide range of materials, such as stainless steel, iron, aluminum, etc., which can be used in metallurgy, petroleum, chemical industry, electrical appliances, shipbuilding, machinery and other industries.

The punch half of the punch/die set is not threaded to accommodate either the manual or hydraulic pull-through bolt/stud. This caused the alteration of the die spacer (thinner) and had to back up the punch with another punch that was threaded! The punch itself worked okay but what a task to get it set-up!
