Shank Diameter: Ø3.2mm
Shape: Cup
Brush: Brass
Deep-clean recessed areas and curved surfaces with the 12.7mm Mini Brass Cup Brush, a specialized tool designed for gentle yet effective scrubbing. The cup shape allows the bristles to flare outward slightly when in use, making it the perfect geometry for cleaning flat-bottomed depressions, internal corners, and shallow pits. Because brass is naturally softer than steel, this brush is ideal for removing tarnish, light corrosion, and dirt from delicate workpieces without gouging or marring the underlying material.
Built for precision, this brush features a standard 3.2mm shank, ensuring universal compatibility with most high-speed rotary tools and grinders. The 12.7mm tip diameter provides a concentrated cleaning footprint, giving you the control needed to target specific areas of oxidation on jewelry, antique hardware, or small engine components. Its balanced design minimizes vibration at high speeds, allowing for a smooth and predictable cleaning experience.
The high-quality brass bristles are non-sparking and exceptionally resilient, making them a safer choice for work environments involving flammable vapors or sensitive electronic components. This brush excels at bringing a bright, satin finish to soft metals such as copper, gold, and silver, as well as cleaning up threaded parts where maintaining the integrity of the metal is vital.
This mini cup brush is an essential asset for restorers, jewelers, and hobbyists who require industrial cleaning power with a soft touch. Whether you are prepping a vintage brass setting or removing carbon buildup from a delicate valve, this tool provides a uniform, clean surface while preserving the fine details of your craftsmanship.

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.
