Shank Diameter: 3.2mm

Shape: Cone
This Mini Grinding Stone is a precision-engineered abrasive accessory designed for detailed carving, internaldeburring, and refining tight geometries. Featuring a 6.4mm cone-shaped head, this tool provides a slim, taperedprofile that strikes the perfect balance between the ultra-fine reach of a micro-bit and the material-removal powerof larger stones. It is particularly effective for smoothing out internal radii, cleaning up small castings, andtapering the edges of holes in hard materials.
The 6.4mm stone diameter allows the tool to fit into narrow channels and acute angles that larger bits cannotaccess, while the pointed tip offers pinpoint accuracy for localized grinding. This conical shape is ideal for’v-grooving’ or creating precise countersinks in metals, glass, and ceramics. The high-quali
