The Sealey 20mm Hole Cutting Screw Punch is the compact option in the range, perfect for creating smaller holes in thin layered materials up to 4mm thick. This size is particularly useful for standard plug holes and smaller tap fittings in sinks and worktops. The tool delivers a smooth, clean circular hole cut into the surface material, providing burr-free results across sheet steel, stainless steel sheets, non-ferrous metals, light metals and plastics. Widely used in the plumbing industry, this 20mm cutter is also valuable for electrical and construction trades where precision holes are required. The high quality steel cutting and bracing edges ensure longevity, whilst the clever design evenly spreads pressure during cutting to eliminate burrs. Operation is straightforwardonce your pilot hole is drilled and the cutter is attached, simply use a spanner to turn the cutter and the thread will apply the required pressure for accurate, clean cutting with no extra finishing needed.
