Dremel 932 Grinding Stones - 9.5mm Pack of 3

These grinding stones are highly versatile and can be used on various materials, including stainless steel, general metals, castings, welded joints, rivets, and rust. They are not recommended for soft or brittle materials where a smoother finish is desired.

Yes, the Dremel 932 Grinding Stones are suitable for sharpening drill bits, chisels, lawnmower blades, and other cutting tools. It's crucial to maintain the correct angle and use light pressure to achieve a sharp and consistent edge.

To secure the stone, fully insert its shank into the Dremel tool's collet. Then, use the collet nut to tighten it firmly. A loose accessory can be dangerous and reduce performance, so always double-check the tightness before operating.

This feature highlights the stone's cylindrical shape and material composition, which are optimized for grinding and shaping angled or tapered surfaces. This allows for precise material removal and detailing in conical shapes or hard-to-reach angles.

The lifespan of a grinding stone varies depending on usage, material being worked on, and pressure applied. Replace the stone when it shows significant wear, chipping, or if it no longer performs effectively. Do not use damaged stones.

Always wear appropriate personal protective equipment, including safety glasses or a face shield, and gloves, to protect yourself from sparks, flying debris, and dust. Ensure good ventilation in your workspace.

Ensure the stone's shank is fully and securely inserted into the Dremel collet. Re-tighten the collet nut. If the issue persists, inspect the stone for damage or an unbalanced shape; replace if necessary.

Reduce the amount of pressure applied during grinding. Ensure you are using the appropriate RPM setting for the material and task. Excessive speed or pressure can accelerate wear. Clean the stone's surface to remove any glazed-over material that reduces its cutting ability.

Increase the Dremel tool's RPM setting, ensuring it is within a safe range for both the accessory and the material. Confirm the stone's surface is clean and not clogged with debris. Verify that the stone is appropriate for the hardness of the material you are working on.
