A Trip to the Plier Factory

Sixth-generation family employee Ryan DeArment holds a billet of C1080 alloy steel where all Channellock tools get their start.

A massive die-forging machine used to form pliers parts out of a yellow-hot billet of steel.

The machine hammers out the parts with nine tons of pressure while bouncing the ground floor of the factory like a continuous earthquake.

Seconds after forging, the rough parts are separated from the scrap metal on a trim press.

The parts are diverted into bins by the lower conveyer belt while the scrap metal rides the upper belt into a large hopper to cool.

After forging, holes are created in the pliers parts by a large punch press.

Precise mating joint surfaces must be milled into the pliers.

The angled grooves in these tongue and groove pliers would be impossible to form with a forging process.

After milling the joint surfaces and shaping the cutting edges, the two halves of a tool are riveted together and the rivet is ground flush as shown on these diagonal cutters.

Pliers' thin cutting edges are laser-hardened (a process I wasn't allowed to photograph), but radio frequency hardening is used to harden the entire head of some tools like these nippers.

As part of the heat-treating process, large batches of pliers are run through a fiery furnace.

Skilled "filers"? inspect and adjust the cutting edges and joints of the tools and make fine adjustments by hand if needed.
