Polystyrene Blade Cutter - Cordless DC

Foam Sales' Cordless Hand Held Polystyrene Blade Cutter is the most powerful in our range of small hand-held hobby cutters. The DC power supply can deliver 18W to produce a blade temperature of up to 350C. 

Our model-making customers will be pleased to know that this cutter is suitable for carving heavy density polystyrene, including XPS, as well as light weight foamed plastics too. 

The Blade Cutter is a handy and economical tool for model makers, and for hobby and craft room applications. The unit is more robust than wand-style models having a shorter, reinforced 60mm blade that is strong and easy to use, ensuring precise, clean cuts.

In twenty seconds the cutter heats to 110C and is then ready for use. The blade will heat to higher temperatures so long as the switch button continues to be depressed. Higher heat is recommended for effective, trouble-free  cutting. See video below.

A summary of the features of our popular DC Polystyrene Blade Cutter is here:
  • The fully charged battery can support 40 minutes of continuous use
  • Charging time is 3.5 hours
  • Battery indicator light turns from red to green when fully charged
  • The cutter features a LED light to illuminate the cutting area
  • The blade is 60mm long, is reinforced, and has a 5mm wide cutting path
  • Heats to usable temperature in 20 seconds and to a maximum of 350C in 40 seconds
  • Switch slides forward to ON position, then the button must be depressed to activate blade heat
  • USB charging cord is supplied with the cutter
  • Protection circuit is built in to protect against overcharging and discharging
  • One year warranty

Tips for use include giving the cutter a rest after prolonged periods of cutting, and not maintaining maximum temperature for long periods. Never tape down the switch into a permanent ON position.

Let the heat do the cutting - there is no benefit in forcing the blade through the polystyrene. Misuse like this resulting in a broken blade is not covered by warranty. See the video here for examples of how the cutter can be used.

Please note that when cutting polystyrene and foamed plastics that there will be a residue of material remaining on the blade or wand after use. This can be scraped or sanded off. This residue is less of an issue when cutting with a fine hot wire.

We use parcel post to ship anywhere in Australia for $10 freight. 

A full 12 month warranty applies to the Blade Cutter, as it does to all Foam Sales' polystyrene cutting tables and foam cutting kits.

this is great

Whilst I was a little concerned at the length of the blade, that concern proved to be unnecessary, this is the best hot knife I have used and works exactly as advertised.
Delivery was earlier than I expected plus I have forwarded my recommendation to a friend and fellow railway modeler in NZ
Many thanks
Robin Smith.
