You will streamline busbar work and electrical installations with the CH-70 hydraulic hole puncher, which delivers a consistent 35-ton punching force across multiple metal thicknesses.
- You handle iron up to 10 mm, aluminum and copper bars up to 12.7 mm, and stainless steel up to 8 mm without manual drilling delays.
- You switch between jobs quickly using the included four-pair tungsten steel die set, which cleanly cuts apertures from 3/8″ to 3/4″ in one stroke.
- You position wider stock easily thanks to the 4.3‑inch deep throat opening, keeping your hands clear while you align flat copper plates and busbars.
- You transport this 75‑lb tool confidently between projects because its reinforced alloy frame protects the hydraulic mechanism during repeated cutting cycles.
