This Mini Grinding Stone is a specialized abrasive tool designed for intricate contouring, hollow-grinding, and internal radius smoothing. Featuring a 9.5mm ball-shaped head (spherical profile), this bit is the ultimate choice for creating uniform concave depressions and cleaning up rounded indentations where flat or pointed stones would leave unwanted gouges. Its perfectly round geometry allows for multi-directional grinding, making it exceptionally easy to blend transitions on irregular surfaces.
The 9.5mm stone diameter provides a substantial contact area for a spherical bit, allowing for efficient material removal while still maintaining the delicate touch required for precision work. Whether you are deburring the inside of a pipe exit, carving smooth channels in wood or stone, or refining the cast lines on metal components, the rounded profile ensures a consistent finish from any angle. The high-grade abrasive composition is engineered to stay cool and resist loading, ensuring the ball maintains its spherical accuracy throughout its life.
Equipped with a standard 3.2mm shank, this ball stone is fully compatible with Dremel and other high-speed rotary tools. The precision-bonded construction ensures the 9.5mm head remains perfectly balanced at high RPMs, providing a smooth, chatter-free experience. This stability is vital when performing detailed 'free-hand' work, as it gives the user the steady control needed to follow complex curves and interior contours without the tool skipping or jumping.
Ideal for jewelers, woodcarvers, and metal fabricators alike, this 9.5mm ball grinding stone is a must-have for any project involving curved geometries. Its ability to create smooth, rounded finishes and reach into spherical recesses makes it one of the most versatile shapes for artistic refinement and mechanical deburring.

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.
