Polax cutting disk 400×21×11 mm 36-005 for metal and stone is a large-diameter abrasive wheel intended for use with angle grinders and cutting machines. The disk has a 400 mm diameter, 21 mm bore and 11 mm thickness, designed to deliver stable straight cuts in a range of construction and fabrication applications. It is manufactured to handle both metal and masonry materials, combining a robust cutting edge with a reinforced body to resist deformation during heavy-duty operation.
Advantages
The cutting disk offers a balance of cutting performance and wheel stability for large-scale tasks. Its wide 11 mm thickness reduces vibration and provides a consistent kerf for straight cuts, while the reinforced construction helps maintain wheel integrity under high load. The disk is suitable for continuous cutting of mixed materials without frequent wheel changes, which can improve jobsite efficiency.
Suitable for
- Casting and structural steel cutting
- Concrete, brick and stone cutting
- On-site renovation and demolition tasks
- Fabrication workshops requiring large-diameter cuts
Key specifications
- Diameter: 400 mm
- Bore (inner hole) diameter: 21 mm
- Thickness: 11 mm
- Material compatibility: metal and stone (masonry)
- Intended tool type: angle grinders and cutting machines
How to use
Fit the disk to a compatible angle grinder or cutting machine with a 21 mm arbor, ensuring the machine is powered off and unplugged or the battery removed. Mount the disk according to the tool manufacturer’s instructions, securing it with the correct flange and nut. Before cutting, check the disk for visible damage or cracks and wear appropriate personal protective equipment such as eye protection, hearing protection and gloves. Allow the machine to reach operating speed before engaging the material and use steady, controlled feed pressure to maintain a straight cut. After use, allow the disk to stop completely before removing guards or handling the wheel.
Usage recommendations
Use the disk within the speed limits and mounting specifications of your grinder. Avoid side pressure or bending forces that the disk is not designed to withstand. For cutting different materials, adjust cutting speed and feed pressure to match material hardness and thickness. Replace the disk if it shows significant wear, crack formation or any deformation.
