Mini Grinding Stone 19.8mm Wheel 3.2mm Shank
Shank Diameter: Ø3.2mm
Stone Diameter: Ø19.8mm
Shape: Wheel
This Mini Grinding Stone is a versatile and efficient abrasive wheel, meticulously designed for surface leveling, edge cleanup, and precision slotting. The wheel geometry provides a generous horizontal contact area, making it significantly more effective than pointed stones for tasks that require a uniform, flat finish across a broader section of your workpiece.
The tool features a 19.8mm wheel-shaped head, offering a mid-sized diameter that balances impressive surface coverage with nimble maneuverability. This disc-like profile is the perfect choice for side-grinding, allowing you to easily smooth down sharp metal edges, remove surface oxidation, or sharpen flat blades. Its high-quality abrasive composition is engineered to maintain a consistent cut on various hard materials, including stainless steel, cast iron, and non-ferrous metals.
Mounted on a precision-engineered 3.2mm shank, this stone is fully compatible with most high-speed rotary tools, including Dremel models. The 19.8mm diameter is specifically chosen to provide a high peripheral speed for faster material removal while remaining compact enough to operate within the guards and attachments of standard rotary tool kits. This ensure a stable, centered rotation that minimizes vibration and hand fatigue during extended use.
Whether you are smoothing out a weld bead, restoring vintage hardware, or deburring a long cut in sheet metal, this wheel-shaped grinding stone provides the durability and professional performance required for a clean finish. Its robust construction resists clogging and uneven wear, ensuring the wheel stays true and effective throughout its service life.

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.
