|This 3M™ Roloc™ Bristle Disc Kit contains 2" bristle discs in three grades: 50, 80, 120. Finer grades are recommended for light-duty applications, like finishing and polishing, and coarser grades are recommended for heavy-duty applications like grinding and deburring. A 2" Roloc TR Disc Pad Holder is also included in the pack. The disc pad optimizes performance of the bristle disc by providing a secure attachment for all applications. Plus, it saves time by eliminating the need to align edges of the disc with the disc pad — the screw aligns the disc, making disc changes quick and easy. The versatile system works with drills, disc sanders, right angle grinders and rotary sanders.|
09-03014 has two units of each grade, and a pad holder.
