Japanese manufacturer Nitto Kohki offers a range of high-performance industrial punches and machine tools distributed in Canada by Dobco Equipment Ltd. The company’s product lineup includes balancer reels, electric drivers, grinders, boring drills, and power-tool accessories, with a specialization in hydraulic and electric punches for metal fabrication.
HA and HS Series Hydraulic Punches
Nitto Kohki’s HA and HS series punches are designed for precision hole-making in metal materials, with key differences in operation and features.
HA Series: Features fully automatic punching, return, and reset functions, along with an emergency stop switch for instant shutdown. These tools operate at a maximum pressure of 10,000 psi and include a hose cord assembly, spanner, sub handle, tool box, and a pre-mounted 22-mm punch and die. Optional accessories include spring balancers, foot switches, and split lock nuts.
HS Series: Equipped with a double-acting hydraulic system for both automatic and manual operation. While maintaining the same 10,000 psi maximum pressure as the HA series, the HS models have longer punching and return cycles. Standard components include a hose cord kit, spanner, sub handle, chip guard, tool box, and a 22-mm punch and die, with optional accessories available.
Both series support punch and die sizes ranging from 8 to 25 mm in diameter.
Electric-Hydraulic Punch for Heavy-Duty Applications
For operations requiring electric power, Nitto Kohki’s E55-0619 self-contained electric-hydraulic punch delivers up to 17 tons of force, capable of creating round or elongated holes in flat bars, angle bars, and channel iron. Key specifications include:
Maximum punching diameter: 13/16 inch
Maximum material thickness: ¼ inch
Customizable punch and die shapes and sizes
The tool comes with a 10×12 mm spanner and a selection of Allen wrenches (3, 4, or 5 mm), with an optional foot switch assembly for hands-free operation.
