Fibre discs FS 964 ACT 4-1/2 x 7/8 (inch) 50 grit

The wide range of available grit sizes makes the FS 964 ACT fibre disc equally well suited for rough grinding and finish grinding on steel. The microcrystalline grain allows the disc to sharpen itself during the grinding process. This effect ensures that the disc will not lose the slightest bit of its aggressiveness while grinding the workpiece. ACT, or Advanced Coating Technology, is the characteristic that sets this fibre disc apart as a premium product because the red coating provides for exceedingly high grit adhesion of the ceramic aluminium oxide grains on the vulcanised fibre backing material.
