Key benefits of using a 3-in-1 Styrofoam cutter

Clean, smooth cuts without mess: Thermal cutting melts the material exactly at the cut point, preventing the formation of annoying Styrofoam crumbs.
3-in-1 versatility: Three different dedicated attachments allow you to go from rough cutting of thick boards to extremely precise artistic engraving.
Short-term cordless operation: When the device is warmed up and the power cable is disconnected, it allows for short-term cordless operation. This is extremely convenient for working in hard-to-reach places or in the field where you do not have direct access to the power grid.
Fast heating and safe operation: The device reaches operating temperature in just a few minutes, and the included convenient stand ensures safe storage of the tool during work.

Three dedicated attachments for complete control over your work
The set contains three different tips that cover all stages of Styrofoam processing - from rough cutting to details:

Cutting bar tip (arc): Allows cutting polystyrene up to 15 cm (150 mm) thick to a depth of 9 cm. This attachment is particularly useful for fast and extremely precise processing and straightening of the sides of polystyrene sheets.
Long knife tip (10 cm): The working tip with a pointed end allows you to start cutting anywhere on the board (plunge cut). Since the tip heats up along the entire 10 cm length, it is ideal for working with sheets and boards up to 10 cm thick.
Short Engraving Knife Tip (3 cm): This ultra-precise tip with a pointed tip allows you to work anywhere on the surface of Styrofoam. It is designed for very precise cutting, creating grooves or engraving any shapes, inscriptions and patterns.

Useful tips for work:
When using hot filament, it is important to wear appropriate protective equipment, such as safety glasses and gloves. It is also important to check that all parts are properly installed and secured before using the hot filament, as improper installation can pose a risk of injury.
