A micro grinding stone shank refers to a small, precision grinding tool used in rotary tools (like Dremel) or die grinders for detailed work such as engraving, deburring, polishing, or shaping hard materials (metal, glass, ceramics, etc.). These stones are mounted on a shank (a straight or tapered shaft) that fits into the tool’s collet or chuck.
Key Features:
1. Material:
– Made from abrasive compounds like aluminum oxide, silicon carbide, or diamond grit.
– Some are reinforced with rubber for flexibility.
2. Shank Size:
– Common shank diameters: 1/8″ (3.175mm), 3mm, or 1/4″ (6mm).
– Smaller shanks (e.g., 1.5mm) are used for ultra-fine work.
3. Shape & Grit:
– Shapes: Cylindrical, conical, spherical, tapered, or wheel-shaped.
– Grit ranges from coarse (#60–#120) to fine (#200–#600+).
4. Applications:
– Metalworking (deburring, weld cleaning).
– Jewelry making (detail grinding).
– Dental/medical tool sharpening.
– DIY crafts and model-making.

Usage Tips:
– Use at medium-to-high RPM (~10,000–30,000 RPM) depending on material hardness.
– Apply light pressure to avoid overheating or breaking the stone.
– Use coolant/lubricant for metals to extend stone life.
