RX-84 Long Arm & Wide Hot Knives
The RX-84 series are general and special purpose hot knives mounted on a 'long-arm' frame for providing extra working area under the knife. The RX-84 models can be fitted with almost any of our hot knife tooling, such as a straight knife, shaped knife, or hole punch, for example. These are ideal for cutting large panels, punching holes in finished goods, cutting sling webbing, or other types of synthetic fabrics.

Brass knives vs. Stainless knives
What's the difference?
Knives that cut using heat must be able to efficiently transfer the thermal energy from the heater core to the knife edge. Brass is the most economical & efficient alloy for this purpose. However, being a relatively soft metal, brass will wear faster than a harder metal such as stainless steel. Stainless steel does not conduct heat as well and must therefore be operated at a higher temperature to do the same work as a brass knife. This uses more energy and may shorten heater life.
MATERIALS NOTICE: Most of these machines use thermal tooling made of brass alloy and cannot be used with materials that contain any chloride compounds, such as PVC. Please contact us for alternate tooling options. Materials that contain any fluoride compounds should not be cut thermally on any models.
