Dobco Equipment supplies industrial power tools by many major manufacturers, such as Nitto Kohki. Headquartered in Tokyo, this company makes a wide range of machine tools, including balancer reels, electric drivers, grinders, boring drills, and power-tool accessories. Another specialty of Nitto Kohki is its punching tools, for making holes in metal.
There are two primary designs available for Nitto Kohki punches – the HA and HS series – as well as an electric option and punches and dies.
Manual and automatic operations
The HA series of punching tools offers such features as fully automatic punches, return and reset operations, emergency switches that can stop operations instantly at any time, and an allowable maximum pressure of 10,000 pounds per square inch (psi). Each tool comes with a hose cord assembly, spanner, sub handle assembly, tool box, 22-millimetre (mm) punch and die mounted on machines, and four-mm Allen wrench. Dobco can supply spring balancers, foot switch assemblies, split lock nuts, and other optional accessories.
Every punch in the SH series has a double-acting hydraulic system that enables both manual and automatic operations. This series offers longer punching and returning times than the HA series has, with an allowable maximum pressure of 10,000 psi, but the same optional accessories. Each of these SH punching tools comes with a hose cord and hose kit assembly, spanner, sub handle assembly, chip guard assembly, tool box, 22-mm punch and die mounted on machines, and four- or five-mm Allen wrench. Punch and dies for both series have size diameters from eight to 25 mm.
Nitto Kohki also manufactures the E55-0619, a self-contained electric and hydraulic punch that can produce round or elongated holes in flat bars, angle bars, and channel iron. This tool has a maximum punching diameter of 13/16 of an inch, a maximum punching thickness of ¼ of an inch, and a maximum output of 17 tons.
Punches and dies for the E55-0619 are available in custom sizes and shapes. It comes with a 10×12 spanner and a three-, four-, or five-mm Allen wrench; a foot switch assembly is optional.
