Product catalog summary
Overview: This document provides specifications and guidelines for using WO round hole punches, which are tools designed for creating holes in sheet metal used in switchgears, desktops, and for installing signal lamps, glands, and buttons.
Specifications:
  • Applicable for sheet metal with a maximum thickness of 2 mm (at Rm<450MPa, e.g., type St3S). When using GW or GW_2 heads, the maximum thickness increases to 3 mm.
  • Constructed from high-strength steel to ensure durability of the punching elements and bolt/pin.
  • For diameters up to ø 38.5 mm, waste is cut into two parts for easier removal. For larger diameters, waste is deformed for easy removal.
Compatibility:
  • Compatible with hand sets, GW, GW 2 hydraulic, and battery-powered punches such as EWHE 80, WHE 80, WH 100, and WHP 1.
  • Note: Bolts and pins must be ordered separately.
  • For toothed punches, a hydraulic drive is recommended.
