Gardner Bender KOS-1000B Slug-Out Mechanical Knockout Set for 1 (2.54 cm) Conduit

The Gardner Bender KOS-1000B is a top - notch mechanical knockout set. Its four - point knockout punches and dies are engineered to create clean, circular holes in 10 - gauge mild steel, 12 - gauge stainless steel, or other soft metals up to 0.135 inches thick. These punches and dies are highly versatile, as they can be interchanged in any combination with most brands of knockouts. This kit comes with a punch, a die, and a drive screw, capable of punching a hole with a diameter suitable for 1 - inch diameter pipe or conduit (the actual hole diameter is 1.973 inches). There are also additional sizes available, which make it incredibly easy to install electrical conduit and pipe of nominal sizes from 1/2' to 4' in all common increments. Key features include a four - point punch design that allows the slug to drop freely from the die without the need for splitting, tapping, or prying. It's compatible with most tool brands, punches through 10 - gauge mild and 12 - gauge stainless steel, and is specifically designed for 1 - inch pipe or conduit. The set includes all the essential components: a punch, a die, and a drive screw.

Using the Gardner Bender KOS - 1000B is a breeze. First, select the right punch and die for the size of the conduit you're working with. Place the material you want to punch a hole in between the punch and the die. Then, use the drive screw to apply pressure gradually until the hole is punched. Make sure you're using the set on suitable materials like 10 - gauge mild steel or 12 - gauge stainless steel. Don't try to use it on materials that are too thick or too hard, as this could damage the set. After each use, clean the punch, die, and drive screw with a dry cloth to remove any debris. Store the set in a dry place to prevent rusting. If you notice any signs of wear, it's a good idea to replace the parts to keep the set working well.
