Mini Abrasive Wheel 25.4mm X 3.2mm Shank
Shank Diameter: Ø3.2mm
Stone Diameter: Ø20mm
Shape: Wheel
This Mini Abrasive Wheel is a high-performance rotary accessory designed for efficient surface preparation, blending, and smoothing. Featuring a 20mm stone diameter with a 25.4mm overall wheel width, this tool provides a generous contact area that makes it an excellent choice for treating larger surface sections quickly while maintaining the precision of a handheld rotary tool.
The wheel-shaped profile is specifically engineered for side-grinding and surface leveling. It excels at removing rust, oxidation, and stubborn burrs from flat metal faces and rounded edges. Unlike pointed or cylindrical stones, the disc geometry of this abrasive wheel allows for a consistent, sweeping motion, ensuring an even finish and preventing the "gouging" that can occur with smaller bits. Its robust abrasive structure is designed to stay cool during operation, reducing the risk of heat damage to delicate workpieces.
Equipped with a standard 3.2mm shank, this wheel is universally compatible with Dremel and other high-speed rotary tools. The balance between the 20mm diameter and the 3.2mm shank provides high peripheral speed for rapid material removal while ensuring the tool remains stable and vibration-free. This stability is critical for achieving a professional-grade finish on metals, alloys, and composite materials.
Whether you are restoring antique hardware, prepping a surface for paint, or smoothing out weld seams, this 25.4mm abrasive wheel delivers reliable results. Its durable construction ensures it maintains its shape even under heavy use, making it a staple for any workshop focused on metalworking, automotive repair, or heavy-duty hobbyist projects.

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.
