Punch down tool, also known as punchdown tool or Krone punch down tool(named after the KRONE LSA-PLUS connector), is a small hand tool used in telecommunication and network. It usually used for inserting wire into insulation displacement connectors on punch down blocks, patch panels, keystone modules, and surface mount boxes.

                        Use krone punch down tool to punch down the wires like this

Most punch down tools are of the impact type, consisting of a handle, an internal spring mechanism, and a removable slotted blade. To use the punch down tool, a wire is pre-positioned into a slotted post, and then the punch down tool is pressed down on top of the wire, over the post. Once the required pressure is reached, the internal spring is triggered, and the blade pushes the wire into the slot, cutting the insulation, and securing the wire. For light-duty use, there are also less expensive punch down tools with fixed blades and no impact mechanism.

When terminating a cable, a special punchdown tool is used to press each piece of cable into the fiber connector and cut off the excess. Using the wrong tool or a screwdriver to do this can ruin the connection. Krone punch down Tool, enables installers to make faster, more uniform connections in Krone wiring blocks with far less effort. Punches down and cuts the wire in a single motion. With a single push, the spring loaded mechanism will trigger the blade at just the right point to seat and cut the wire to size. On/Off selector turns on and off the cutting function. Tool also includes a fold-out wire hook and spudger tip in the handle. The Krone punch down tool is small and compact, for easy storage and transportation.

To accommodate different fiber connectors types, 66, 110, BIX and krone require different blades. Removable blades for 66 or 110 are often double-ended, with one end that only inserts the wire for daisy-chain wiring from post to post, and another end that inserts wire and trims the excess length for termination at a post. Krone blades require a separate scissor-like mechanism for trimming the wire. The trimming blade cutting edge works against the plastic insulating post.
