Ogura HPC-NF188W Electro-Hydraulic Hole Punchers

Product Made in Japan
Manufacturer: Ogura
Model: HPC-NF188W

Features of HPC-NF188W

The new “N” series punchers are double-acting and have a newly designed punch holder for longer life. The punch is also redesigned so that only one “N” series punch is required to punch the range of materials: mild steel, stainless steel, angle iron, and channel steel. The center of the punch has been made wider for easier positioning.

  • Both punching and retracting are completed by hydraulic power. This solves the “punch jammed” problem and allows faster work at the site.
  • As a result of reviewing the basic structure of the tool from the user’s point of view, we changed the design of the die, punch & punch holder to make them more durable and to make the setting of the punch & die easier.
  • Only one die for flat bar, angle steel and channel flange. It is not necessary to change the die when punching different materials or thicknesses.
    ∗Thinner material (t2-3.2mm) may have some burrs or deformation.

  • “Double acting” hydraulic return for jam free operation.
  • New punch design makes it easier to confirm the hole position.
  • Hole puncher is specifically designed to provide high quality holes quickly and efficiently.
  • MAX. HOLE SIZE: φ18 ⁄ t8mm(MILD STEEL)
