This high capacity battery hydraulic knockout punch tool can punch up to 4 inch holes in 12-gauge stainless steel.

Hand operated hydraulic hole punching tool 120kN. 

It's suitable for punching round, square and rectangular holes up to max. 3.5 mm material thickness

1. Technical Parameter of Battery Hydraulic Knockout Punch Tools

2. Feature for Battery Hydraulic Knockout Punch Tools

1. Microcomputer control system automatically detects the pressure when it is crimping, with double safety protection.

2. Pressure is released automatically The tool stops forcing the pressing and releases 90% pressure when the pressure reaches maximum.

3. The tool is equipped with a double piston pump which is characterized by a fast approach towards the connecting material and 

transfer to high pressure automatically by slow crimping

4. The crimping head can be smoothly turned 350° Around the longitudinal axis to gain better access to tight corners and other difficult working areas.

5. An acoustic signal sounds and a red display flashes if a deviation from the set operation pressure or low battery charges is identified.

6. One key controls the trigger to start working, half loosing the trigger means stopping forcing pressure, and losing fully means the piston returns to the original position.

Li-ion batteries do neither have a memory effect nor self-discharge. Even after long periods of non-operation, the tool is always ready to operate. 

In addition, we see a power-weight ratio of 50% more

Capacity and shorter charging cycles compared to NiMH batteries.

7. A temperature sensor makes the tools stop working automatically when the temperature is over 60º C 

After a long time of working, the fault signal sounds, which means the tool can't continue work until the temperature is reduced to normal.
