The Styrofoam Cutter up to 450°C - Hot Groove Knife (SKU: G81210 or M51320) is a top-of-the-line thermal knife designed for fast and clean processing of various polymer materials. Forget about laborious manual cutting, which causes mountains of useless waste and annoying Styrofoam crumbs. With this powerful hot knife, you will get the job done much faster, extremely precisely and, above all, without unnecessary dirt on the job site.\u003cbr\u003e This versatile thermal cutter is an indispensable tool for facade designers, builders, installers, modelers and DIYers. It allows you to easily create grooves for cables, pipes and other installations and ensures perfectly smooth edges without fraying the material. Whether you are arranging the thermal insulation of a building or creating precise models, this hot knife will become your favorite tool.\u003cbr\u003e Why choose a professional thermal styrofoam cutter?\u003cbr\u003e Classic methods of cutting Styrofoam, such as ordinary hand saws, olfa knives or wire cutters without regulation, leave behind a huge amount of fine particles. These static particles stick to all surfaces, clothes and tools, and their cleaning is extremely time-consuming. The hot groove knife works according to the advanced principle of thermal cutting, which means that the material melts precisely at the cut point. The result is a perfectly straight, smooth and closed edge, which prevents the material from crumbling later. The device is ergonomically designed, easy to use and ready to work in just a few moments.\u003cbr\u003e The main advantages and benefits of using a hot knife\u003cbr\u003e\u003cbr\u003e Clean and precise cuts without mess: Since the hot blade melts the material at the cut point, there is no dust or annoying polystyrene chipping while working. Your working environment remains clean and tidy.\u003cbr\u003e Versatile use on various polymers: The tool is ideal for cutting, shaping and gouging polymers such as PP (polypropylene), PVC (polyvinyl chloride) and EPS (expanded polystyrene or styrofoam).\u003cbr\u003e Adjustable cutting depth for perfect grooves: The built-in slider allows for quick and easy adjustment of the blade's working length, which is crucial when creating grooves of uniform depth for installations.\u003cbr\u003e Precise 5-level heat control: Allows you to set the optimal temperature based on the thickness, density and type of material you are working on, preventing overheating or jamming.\u003cbr\u003e Extremely fast heat-up: The device reaches operating temperature in just a few seconds, saving you valuable time on the construction site or in the home workshop.\u003cbr\u003e\u003cbr\u003e Technical specifications and features of the device\u003cbr\u003e The 450°C Styrofoam cutter is designed with long-term durability, high performance and user safety in mind. Below are the key technical specifications of the device:\u003cbr\u003e\u003cbr\u003e Product code (SKU): G81210 or M51320\u003cbr\u003e Supply voltage: 230 V (standard mains)\u003cbr\u003e Temperature setting range: from 100°C to 450°C\u003cbr\u003e Blade working length adjustment: easily adjustable from 15 mm to 100 mm using the integrated slider\u003cbr\u003e Temperature control system: 5-level manual control for optimal cutting results\u003cbr\u003e Product color: Random (depending on current stock availability)\u003cbr\u003e\u003cbr\u003e Precise 5-level temperature setting for each material\u003cbr\u003e Different polymer materials require different temperature regimes for optimal cutting. Too low a temperature can cause the blade to bind and drag, while too high a temperature can cause excessive melting and edge deformation. That's why this hot knife is equipped with a convenient and precise 5-level heat regulator:\u003cbr\u003e\u003cbr\u003e Level 1 (100°C): Suitable for more delicate, thinner materials and precise fine corrections.\u003cbr\u003e Level 2 (160°C): Ideal temperature range for easier shaping of sensitive polymers.\u003cbr\u003e Level 3 (230°C): Optimal and most commonly used temperature for standard processing of EPS (Styrofoam).\u003cbr\u003e Level 4 (360°C): Fast and smooth cutting of denser insulation boards and harder materials.\u003cbr\u003e Level 5 (450°C): Maximum power and temperature for the most demanding projects and harder polymer mixtures.\u003cbr\u003e\u003cbr\u003e Using a hot knife in practice\u003cbr\u003e This hot groove knife is extremely popular when installing facade insulation and carrying out finishing work. With it, you can easily and in seconds cut grooves for electrical cables, drain pipes, underfloor heating or create unique decorative profiles on the facade. The adjustable blade (from 15 to 100 mm) gives you full control over the cutting depth, meaning you will never accidentally cut through the insulation board deeper than intended.\u003cbr\u003e Thanks to its lightweight design and ergonomic handle, the device does not tire your hands even during long work sessions. The blade glides smoothly through the material, allowing you to create perfect curves, straight lines and complex shapes without any effort.\u003cbr\u003e For a better idea of the device's operation, speed, and exceptional efficiency, watch the video below, which shows the practical use of this top-of-the-line thermal knife in real-world conditions:\u003cbr\u003e Video demonstration of operation:\u003cbr\u003e Watch a video demonstration of the Styrofoam cutter on YouTube\u003cbr\u003e Frequently Asked Questions (FAQ) about the product\u003cbr\u003e What materials can I cut with this thermal knife?\u003cbr\u003e The device is primarily intended for cutting and shaping elements from various types of polymers. It is most often used for EPS (expanded polystyrene or styrofoam), but it also performs exceptionally well in processing PP (polypropylene) and PVC (polyvinyl chloride).\u003cbr\u003e How does the groove blade length adjustment work?\u003cbr\u003e A practical and reliable slider is located on the body of the device. With it, you can easily determine how much of the blade will be exposed and will enter the material. The working length can be adjusted arbitrarily and precisely in the range from 15 mm to 100 mm, which allows you to make grooves of any depth.\u003cbr\u003e Does the device overheat during prolonged operation?\u003cbr\u003e The cutter is designed for safe and stable operation when used in accordance with the instructions for use. For optimal performance, we recommend that you select the appropriate temperature level (from 1 to 5) depending on the material you are cutting. During prolonged continuous operation, allow the device to take short breaks to cool down from time to time, which will significantly extend the life of the heater and the blade itself.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e Responsible persons:\u003cbr\u003e GEKO - GEKO SPÓŁKA Z OGRANICZNĄ ODPOWIEDZIALNOŚCIA SPÓŁKA KOMANDYTOWA, ul.
