Accessories for thermal knives
Blades for the Minova hot knife – for cutting EPS and XPS polystyrene
Blades for the Minova thermal knife are available in the following lengths 15 cm i 20 cm and are used for precise cutting of polystyrene (EPS) and expanded polystyrene (XPS). Made of a durable high-strength alloy, they do not bend when working with hard materials. They fit Minova knives and most thermal knives from other manufacturers. Prices starting at 49 zł.
Comparison of Minova Blades
| Model | Length | Knife Type | Application | Material | Price |
|---|---|---|---|---|---|
| 15 cm Minova Blade | 15 cm (150 mm) | Thermal | Precision machining of parts, rustication, grooves, and EPS/XPS profiling | Metal alloys (rigid) | 49 zł |
| 20 cm Minova Blade | 20 cm (200 mm) | Thermal | Cutting thick EPS/XPS facade panels in a single pass | Stop (rigid) | 55 zł |
| 30 cm Blade W01 | 30 cm (300 mm) | Mechanical W01 | Cutting thick insulation: mineral wool, thick foam | Metal alloys (rigid) | 49 zł |
How do you choose the right blade length for the job?
The length of the blade determines the cutting depth and how comfortable it is to use. The blade 15 cm It works well for tasks requiring precision: cutting grooves, making channels for utilities, and profiling the edges of panels. The blade 20 cm It is designed for effortlessly cutting through thick facade panels—it allows you to cut through polystyrene or XPS in a single stroke without having to rotate the panel. The blade 30 cm It is compatible only with the Minova W01 mechanical knife and is designed for cutting mineral wool and very thick insulation materials.
Compatibility and Installation
The 15 cm and 20 cm thermal blades feature a universal mounting system—they fit Minova thermal knives (30Y, 30D) as well as most thermal knives from other manufacturers available on the market. The 30 cm mechanical blade is designed exclusively for the Minova W01 knife. To replace the blade in a thermal knife, disconnect the device from the power source, loosen the mounting screw, remove the old blade, and install the new one. Before reconnecting the device, make sure the blade is securely seated in the holder.
Blade Material and Durability
Minova blades are made of a durable metal alloy (resistance alloy), which ensures adequate rigidity along their entire length and prevents them from bending when cutting hard XPS. The material does not exhibit plastic deformation when repeatedly heated to the operating temperatures of a thermal knife. The manufacturer’s warranty is 12 months.
Types of Blades for a Thermal Knife
This category includes two types of thermal blades—which differ in length and intended use—and one blade for a mechanical knife:
- 15 cm thermal blade – Short, rigid, for precise machining of workpieces. Ideal for cutting facade rustication, grooves for electrical wiring, and profiling the edges of polystyrene (EPS) and expanded polystyrene (XPS).
- 20 cm thermal blade – for easy cutting of thicker panels. Designed for use on facades and thermal insulation where cuts must be made immediately to the full depth of the panel.
- 30 cm Mechanical Blade (W01) – A long, rigid blade for the W01 power knife. Designed for cutting thick layers of mineral wool and heavy insulation where a heat knife is not suitable.
FAQ – Frequently Asked Questions About Thermal Knife Blades
What blade lengths are available for thermal knives?
The Pro-Cut product line includes thermal blades in the following lengths: 15 cm i 20 cm. The 30-cm blade is designed for the W01 mechanical knife, not for thermal knives.
Do the blades fit knives from brands other than Minova?
Yes—the 15-cm and 20-cm thermal blades have a universal mounting system and fit most thermal knives available on the market without any problems. The 30-cm mechanical blade is designed exclusively for the Minova W01 knife.
What materials can be cut with thermal knife blades?
Minova thermal blades are designed for cutting expanded polystyrene (EPS) and extruded polystyrene (XPS). A thermal knife with a 15-cm blade allows you to cut grooves and ridges, while a 20-cm blade enables you to completely cut through thick facade panels. For mineral wool and PIR/PUR foams, use separate mechanical knives or dedicated blades.
How do you install a blade on a heat knife?
Unplug the knife. Loosen the screw that secures the blade. Remove the old blade and insert the new one. Tighten the screw and check that the blade is securely fastened before plugging the device back in.
How much do the blades for the Minova thermal knife cost?
A 15-cm blade costs 49 zł, 20 cm blade – 55 zł. 30-cm mechanical blade (W01) – 49 zł. Free GLS shipping on orders over 500 zł.
Are the blades for a thermal knife universal?
The 15-cm and 20-cm thermal blades feature a universal mounting system and are compatible with Minova knives as well as most thermal knives from other manufacturers. The 30-cm mechanical blade is designed exclusively for the Minova W01 knife—it is not compatible with thermal knives.
