Mini Cut-off Wheel Reinforced 31.8mm X 1.1mm
Diameter: Ø31.8mm
Inside Diameter: Ø2.3mm
This Reinforced Mini Cut-Off Wheel is a high-performance abrasive tool designed for heavy-duty cutting, trimming, and slotting tasks that require extra durability. Featuring a 31.8mm diameter and a thin 1.1mm profile, this wheel provides a balanced combination of rapid cutting speed and structural integrity. It is an essential accessory for DIY enthusiasts, automotive hobbyists, and metalworkers who need a reliable solution for slicing through tough materials where standard, non-reinforced discs might shatter.
The defining characteristic of this wheel is its fiberglass reinforcement, which runs through the center of the abrasive material. This internal mesh significantly increases the wheel's tensile strength, allowing it to withstand the high lateral pressures and centrifugal forces generated by high-speed rotary tools. This added safety feature makes it much more resilient against breakage if the tool tilts or binds during a cut, providing a safer and more confident user experience during demanding projects.
Engineered for versatility, the 1.1mm thickness ensures a narrow kerf, resulting in clean, precise cuts with minimal material wastage. It is exceptionally effective at slicing through a wide range of hardened materials, including stainless steel, iron, aluminum, and various plastics or composites. Whether you are shortening a rusted bolt, trimming a metal rod for a model, or cutting a custom slot in a plastic housing, this wheel delivers a smooth, burr-free finish that saves time on secondary sanding.
Designed to be mounted on a standard mandrel, this cut-off wheel is optimized for high-RPM performance, ensuring that the abrasive grains remain sharp throughout the life of the disc. Its larger 31.8mm diameter offers an extended reach and a longer service life compared to smaller discs, making it a cost-effective choice for frequent use. From precision repair work to creative metal fabrication, this reinforced wheel provides the rugged cutting power needed for high-definition results.

The shank of the rotary cutter is securely locked in place by fitting it in the corresponding collet or making use of a keyless chuck.
Rotation speed:
Most rotary tools have the benefit to adjust the rotation speed. Many tool bits that fit in rotary tools have a maximum speed setting. This can normally be found on the packaging.
All materials react differently to speed and will need the tool bit to rotate slower. It is recommended to start using accessories on the slower speed first, before increasing the speed as needed.
The diameter of the tool bit fitted also determines the rotation speed. The larger the diameter, the slower the speed. If the speed is set too high, it could bend the shank/shaft resulting in injury.
