Nitto Kohki industrial power tools are available to the Canadian market through Dobco Equipment Ltd.

The Model HA11-1624 punch offers a maximum punching thickness of 16 millimetres (mm) and maximum punching diameter of 24 mm.

As the rest of the HA series does, the Model HA11-1624 provides fully automatic punch, return, and reset operations, while its emergency switch returns the punch at any time.

With several useful accessories included

The Model HA11-1624 portable hydraulic puncher by Nitto Kohki is designed to punch both round and oblong holes, depending on the specific application. Measuring 545.6 by 436 mm, the tool has a maximum throat depth of 110 mm. Among the other technical specifications: a hole-making time of 16½ seconds; a return time of only one second; an allowable maximum pressure of 700 kilograms-force per square centimetre; maximum output of 431 kilonewtons; ram stroke of 25 mm; and a mass of 35½ kilograms. In the case of mild steel, the user must determine the maximum punching thickness based on the equation of 0.8 times the punching diameter.
