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 halogen 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.



RX-80-SBL This standard stainless steel hot knife is durable and ideal for many light-duty cutting applications. One of our most popular (and most copied) models!

Use for cutting lightweight nylon, polypropylene, ribbon and cord as used on packs, bags and hairbows.

RX-80-BDL   The "original" RX-80 model first manufactured in 1998. A special-purpose, standard-duty brass knife for knife for many hot knife applications. The smaller angle on this knife edge, compared to the other models, slightly reduces the meltback, or "burr", typically formed when heat cutting.
