Paragon PKM-9D Heat Treating Furnace

Machine shops save time with a furnace at their disposal in their own shop. You will no longer send a die out for heat treating, wait for its return and then send it out again for additional heat treating. The PKM-9D, our smallest standard-order furnace, measures 8 1/2” wide, 4 1/2” high and 9” deep inside. The PKM-9D is small, but powerful. It will reach 1850° F. within 45 minutes. The PKM-9D fires on a 120 volt, 20 amp circuit.

Solid construction

The door swings open with one-handed operation. A counter-weight handle holds the door securely closed. The door has a vent hole, so you can see inside the furnace during firing. Metal covers seal the vent holes when not in use. (Always wear Paragon firing safety glasses when looking into a hot furnace.) The furnace is insulated with refractory firebrick. The elements are mounted in dropped, recessed grooves machined into the firebrick. Paragon invented this type of groove in 1952. This groove protects the element for long life and low maintenance. Elements are simple to replace because they’re exposed rather than embedded. You can thread new elements into place following clear instructions in the manual.

The firing chamber is protected by a steel case painted in high temperature blue. A built-in stand lifts the firing chamber safely off your work table, so no extra stand is needed. The door is mounted with a heavy duty hinge for smooth opening. A micro-switch shuts off the power to the elements when the door is opened. We use high temperature wire in the switch box for long life. A heat shield, mounted between the switch box and furnace, helps keep the switch box components cool even during extended operation. To further dissipate heat, the switch box is extra large and generously louvered. Each furnace comes with a cord and plug for immediate installation and a one year warranty.

Optional Knife Making Kit: Contains 1 pair hot gloves, 1 heat treating fork, 4 knifeholders, and 8 firebrick supports. 60.00
