Mini Carbon Steel Brush 12.7mm Cup 3.2mm Shank
Tip Diameter: Ø12.7mm
Shank Diameter: Ø3.2mm
Shape: Cup
Brush: Carbon Steel
Power through stubborn surface contaminants with the 12.7mm Mini Carbon Steel Cup Brush, a heavy-duty solution for intensive cleaning in recessed areas. The specialized cup shape allows the high-tensile steel bristles to focus their energy downward, making it the ideal tool for scouring flat bottoms, internal corners, and shallow depressions where a standard wheel cannot reach.
Featuring a precision-ground 3.2mm shank, this brush is fully compatible with most high-speed rotary tools. The 12.7mm tip diameter offers a compact footprint, allowing you to apply concentrated abrasive force to specific areas. This design is particularly effective at removing heavy rust, weld splatter, and thick oxidation from metal workpieces without the need for harsh chemicals.
The bristles are crafted from premium carbon steel, known for its exceptional hardness and aggressive cutting ability. This makes the cup brush perfect for prepping metal surfaces for paint or coatings, as the crimped wire fibers create a consistent "key" or texture on the material. The robust construction ensures the brush maintains its integrity under the heat and friction of high-RPM operation.
This tool is an essential for metalworkers, restorers, and DIY enthusiasts dealing with iron, steel, or other hard alloys. Whether you are cleaning out the head of a rusted bolt or restoring the internal surface of a metal casting, this carbon steel cup brush provides the industrial-strength cleaning power required for a professional-grade restoration.

The shank of the rotary cutter is securely locked in place by fitting it in the corresponding collet or making use of a keyless chuck.
Rotation speed:
Most rotary tools have the benefit to adjust the rotation speed. Many tool bits that fit in rotary tools have a maximum speed setting. This can normally be found on the packaging.
All materials react differently to speed and will need the tool bit to rotate slower. It is recommended to start using accessories on the slower speed first, before increasing the speed as needed.
The diameter of the tool bit fitted also determines the rotation speed. The larger the diameter, the slower the speed. If the speed is set too high, it could bend the shank/shaft resulting in injury.
