Compared with bristles made of metal or hard materials, flexible bristles require less pressure and are less likely to scratch the surface. The bristles remain corrosion-resistant for a long time and can be used for a long time without frequent replacement. Our abrasive bristle discs can be used with most multi-purpose tools including drills, rotary tools and small grinders. Applications include general industrial, aerospace, automotive, diesel, metalworking, transportation and heavy equipment and other materials requiring fine detail. Please adjust the speed and pressure of the grinding disc according to the work requirements, too high speed and too much pressure may cause the bristles to fall off, material damage or other safety problems. To extend the service life, it is necessary to regularly remove the material debris and dirt attached to the bristles after use.
