Mini Cut-off Wheel Extra Large 38.1mm X 1.2mm
Diameter: Ø38.1mm
Inside Diameter: Ø2.3mm
This Extra Large Mini Cut-Off Wheel is a robust abrasive solution designed for users who need maximum reach and cutting depth from their rotary tools. Featuring a substantial 38.1mm (1.5") diameter and a 1.2mm thickness, this wheel is significantly larger than standard hobby discs, making it the ideal choice for slicing through thicker workpieces. Its increased surface area not only allows for deeper cuts but also ensures a longer tool life, as there is more abrasive material to work with before the wheel needs replacing.
The wheel is engineered for high-efficiency material removal, providing the torque and stability required for demanding demolition or fabrication tasks. The 1.2mm profile offers a slightly sturdier build compared to ultra-thin discs, providing the structural rigidity needed to maintain a straight line when cutting through tougher substrates. This makes it an excellent "workhorse" for automotive repairs, plumbing adjustments, and large-scale model engineering where precision and power must go hand-in-hand.
Versatility is a core feature of this extra-large disc, as it is capable of slicing through a wide spectrum of materials including hardened steel, non-ferrous metals, plastics, and thick composites. Whether you are cutting off a protruding rusted bolt, trimming metal tubing, or creating long slots in a custom housing, the 38.1mm diameter provides a smoother, more stable cutting arc. This results in a cleaner finish with reduced vibration, allowing for better control throughout the entire duration of the cut.
Designed for use with standard heavy-duty mandrels, this cut-off wheel is optimized to perform at high RPMs without compromising safety or accuracy. Its oversized footprint is particularly useful for reaching into tight spaces where the body of the rotary tool might otherwise obstruct a smaller disc. For the craftsman who frequently tackles "big" small projects, this extra-large cut-off wheel provides the professional-grade capacity and durability needed to get the job done quickly and effectively.

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.
