Abrasive Spindle Brush 3M MN-AC for 6 mm Shaft, 150×12×25.4 mm

The Abrasive Spindle Brush 3M MN-AC for 6 mm Shaft, 150×12×25.4 mm is a cylindrical abrasive brush designed for mounting on compatible power tools and rotary shafts. It delivers consistent abrasive action for surface finishing, deburring and light material removal on metals, wood and composite materials. Its compact dimensions make it suitable for edge work, grooves and confined areas where controlled material removal and surface preparation are required.

Advantages

The brush provides uniform abrasive contact across the working surface and maintains stable concentric rotation on a 6 mm shaft. Its construction balances flexibility and abrasive aggressiveness to allow controlled deburring without excessive stock removal. The compact 150×12×25.4 mm size enables access to narrow or recessed areas, while the spindle format ensures quick mounting on compatible rotary equipment. The design supports repeatable results and reduces the need for manual finishing steps.

Suitable for

• Deburring edges and removing flash from metal and plastic castings
• Surface finishing and satin-ing of small metal parts
• Cleaning weld seams and preparing surfaces for painting or bonding
• Light material removal on wood and composite components
• Detail work in workshops, toolrooms and industrial maintenance

• Mounting: spindle format for direct fit on compatible rotary tools

How to use

Install the abrasive spindle brush on a rotary shaft or power tool collet compatible with a 6 mm shaft, ensuring the brush is securely seated and concentric before operation. Select an appropriate tool speed for the material and task—lower speeds for delicate finishes and higher speeds for more aggressive deburring—while following the tool manufacturer’s safety guidance. Apply light, even pressure and move the brush along the workpiece to achieve consistent finishing; avoid excessive force that could reduce brush life or damage the part. Inspect the brush periodically for wear and replace when abrasive action diminishes or if the hub is damaged.
