Material Thickness Limitation

Do not exceed the maximum material cutting capacities (up to 18-gauge for stainless steel and 16-gauge for mild steel). Attempting to punch thicker materials may damage the dies, punches, or driver, and could result in tool failure or personal injury.

Eye and Personal Protection|Always wear appropriate personal protective equipment, including safety goggles and protective gloves, when operating this knockout punch set. Metal shards, sharp burrs, or flying debris can cause severe injury during the cutting process.

Proper Tool Operation|Ensure all components—including the impact bearing driver, adapter, and set nuts—are properly aligned, fully threaded, and securely tightened before applying force with an impact driver. Misalignment or improper setup can cause tool breakage.
