This Mini Grinding Stone is a high-precision abrasive tool designed for intricate detailing, finishing, and surface refinement. Featuring a 7.1mm round point head, this stone offers a compact spherical profile that provides exceptional control when working on small-scale projects. Its rounded geometry is specifically engineered for smoothing concave surfaces, cleaning out circular indents, and blending contours where larger or flat-faced tools cannot reach.
Constructed from premium abrasive materials, the stone is built to maintain its shape while delivering consistent material removal. It is highly effective for deburring and polishing a wide range of hard surfaces, including metals, glass, ceramics, and stone. The smaller 7.1mm diameter makes it a favorite for jewelers, model makers, and technicians who require a delicate touch for fine-tuning intricate workpieces without removing excess material.
The stone is mounted on a standard 3.2mm shank, ensuring a universal fit with most high-speed rotary tools and Dremel handpieces. This precision-engineered shank provides a secure, centered connection, allowing for vibration-free operation at high RPMs. This stability is crucial when performing high-accuracy tasks, such as etching fine details or refining the internal edges of a delicate casting.
Whether you are smoothing the inside of a ring, cleaning up a small weld, or carving detail into a stone sculpture, this 7.1mm round point stone provides a professional-grade finish. Its durable bond is designed to resist heat buildup, extending the life of the tool and ensuring it remains a reliable part of your workshop arsenal for countless projects.

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.
