6mm 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.
Uniform and fine grit | Sharp and wear-resistant | High hardness | High toughness | Resistant to grit loss

IV. Scope of Application
Materials: Specific Applications
Metals: Rust removal, deburring, weld seam grinding, chamfering, and polishing of stainless steel, aluminum alloy, copper, iron parts, and die steel
Stone: Carving and finishing of marble and granite; edge grinding
Wood Carving: Detailed carving and finishing of hardwood and rosewood; polishing of curved surfaces
Plastic: Deburring of plastic parts; surface finishing
Molds: Precision grinding of mold cavities, deep holes, irregular surfaces, internal circles, fillets, grooves, and tapered surfaces
V. Usage Recommendations
Installation: Insert the grinding head shank into the chuck of an electric drill or angle grinder, ensuring it is securely locked in place
Speed: Recommended speed range is 10,000–30,000 RPM; adjust appropriately based on the hardness of the material
Pressure: Apply light pressure while grinding; avoid excessive force to prevent excessive wear on the grinding head or overheating of the workpiece
Safety: We recommend wearing safety goggles and a dust mask to prevent inhaling dust.
Storage: Store in a dry place to prevent moisture from affecting the abrasive’s performance.
VI. Important Notes
This product is mass-produced; reasonable dimensional tolerances may apply. Please refer to the actual item upon receipt.
The color of grinding heads may vary slightly between batches, but this does not affect performance.
Customers concerned about dimensional tolerances should exercise caution before purchasing.
