3mm Shank Red Corundum “Fire Stone” Grinding Wheels are suitable for use with electric drills and grinders to grind metal, stone, wood carvings, plastic, and molds. Available in multiple shapes—T-shaped, cylindrical, conical, spherical, and funnel-shaped—these high-hardness, wear-resistant wheels provide a one-stop solution for rust removal, grinding, deburring, and polishing.
I. Product Overview
Fire Stone Red Corundum grinding heads, also known as small shank-mounted grinding wheels, are manufactured using high-quality red corundum abrasive and ceramic bonding agents through a precision sintering process. Featuring sharp abrasive grains, high bonding strength, and excellent concentricity, they are specifically designed for handheld rotary tools such as electric drills, angle grinders, and suspended grinders. Whether for metal rust removal and grinding, mold dressing, stone carving, wood carving polishing, or plastic part deburring, this grinding head is up to the task.
