Mini Grinding Stone 3.2mm Bullet 3.2mm Shank
Shank Diameter: Ø3.2mm
Stone Diameter: Ø3.2mm
Shape: Bullet
This Mini Grinding Stone is an elite precision tool specifically engineered for high-detail work and micro-finishing. Featuring a slender 3.2mm bullet-shaped head, it provides a unique tapered geometry that allows for surgical accuracy in the tightest workspaces. The pointed tip is ideal for pinpoint material removal, while the rounded body enables smooth transitions and blending in narrow channels.
This stone's specialized profile makes it an essential asset for intricate tasks such as cleaning up small castings, engraving fine details, or deburring the interior of tiny orifices. Its high-grade abrasive composition ensures it can tackle a variety of tough materials, including hardened steel, precious metals, and ceramics, without losing its sharp point prematurely.
Built for versatility, the stone is mounted on a standard 3.2mm shank, making it fully compatible with Dremel and other high-speed rotary tools. Because the head and shank share the same diameter, this tool offers a streamlined, "needle-point" design that can reach deep into recessed areas or thin tubing where larger bullet stones would be obstructed.
Whether you are a professional jeweler, a dental technician, or a hobbyist working on micro-models, this 3.2mm bullet stone provides the delicate touch required for expert-level results. Its durable construction minimizes vibration at high RPMs, giving you the steady control needed to execute fine repairs and artistic refinements with total confidence.

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.
