Mini Grinding Stone 15.9mm Disc 3.2mm Shank
Shank Diameter: Ø3.2mm
Stone Diameter: Ø15.9mm
Shape: Disc
This Mini Grinding Stone is a versatile and efficient abrasive tool designed for surface leveling, edge smoothing, and material blending. Featuring a 15.9mm disc-shaped head, this bit provides a flat, wide grinding surface that is far more effective for treating larger areas than pointed or cylindrical stones. The disc profile allows you to apply consistent pressure across a broader plane, making it the ideal choice for removing rust, smoothing out weld seams, or leveling high spots on metal, glass, and stone workpieces.
The 15.9mm stone diameter offers a high peripheral speed, which translates to faster material removal and a cleaner finish. Unlike thicker wheels, this slim disc geometry allows you to reach into narrow slots or perform precise side-grinding with better visibility of the contact point. The stone is crafted from premium-grade abrasive material that is engineered to stay sharp and resist loading, ensuring that the disc maintains its flat geometry even during extended use on hardened alloys or ceramics.
Equipped with a standard 3.2mm shank, this disc stone is fully compatible with Dremel and other high-speed rotary tools. The precision-bonded construction ensures the disc remains perfectly centered and balanced at high RPMs, which is critical for preventing vibration and "chatter" marks on your finished surface. This stability gives the user exceptional control, whether you are performing heavy-duty stock removal or light surface preparation before a final polish.
Whether you are a metal fabricator cleaning up a workpiece, a restoration specialist removing oxidation from antique hardware, or a hobbyist refining a DIY project, this 15.9mm disc grinding stone is a must-have accessory. Its combination of surface area and precision maneuverability makes it an indispensable tool for achieving professional-grade, flat finishes in any workshop environment.

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 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.
