Reach the most inaccessible details with the 3.2mm Mini Brass End Brush, a precision instrument designed for surgical cleaning and polishing in exceptionally tight spaces. The slender end-shape profile directs the bristles forward, allowing you to penetrate deep into blind holes, narrow grooves, and fine engravings where wider brushes simply cannot reach. Because brass is a softer filament, it effectively lifts away tarnish and debris without damaging the delicate base metal or the sharp edges of your workpiece.
This specialized detailing tool is fitted with a 2.4mm shank, making it perfectly compatible with precision rotary tools, micro-motors, and high-speed handpieces commonly used in the jewelry and watchmaking industries. The compact 3.2mm tip diameter offers a pencil-like accuracy, giving you total control to remove oxidation or carbon buildup from a localized area without scuffing the surrounding finish.
Crafted from premium, non-sparking brass, the bristles are ideal for work on sensitive materials such as gold, silver, copper, and thin-walled tubing. Unlike steel wire, these brass fibers provide a gentle scrubbing action that results in a bright, satin-like luster rather than heavy scratches. The high-density bristle arrangement ensures that the tool maintains its shape and stiffness even under high-speed rotation, providing consistent cleaning power in every crevice.
Whether you are a master jeweler cleaning a complex stone setting, an instrument technician removing corrosion from small electrical contacts, or a hobbyist restoring a vintage model, this mini end brush is a critical addition to your bench. It offers the rare combination of industrial cleaning capability and fine-motor precision, ensuring that even the smallest hidden surfaces receive a professional-grade finish.

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.
