The A15S Wire Grinding Stone Pencil is a specialized, pencil-shaped abrasive stone mounted on a heavy-duty steel shaft, engineered specifically for high-speed tire repair and industrial steel-wire trimming.
Designed to withstand rigorous use in retreading shops, this hardbound aluminum oxide stone quickly cuts, trims, and cleans away exposed, damaged steel belts and wire cords surrounding tire injuries. Its tapered pencil-point profile allows for precise control in tight recesses with minimal smoking or rubber scorching.
