The unique construction of the Scotch-Brite™ disc is made up of non-woven fibres and aluminium oxide abrasive making it tough and durable. Compared to traditional abrasives that quickly wear down when used, this discs high cut-rate, hardness, strength and low heat retention make aluminium oxide a popular choice.

The plastic threaded button or screw is designed to easily and quickly screw on a Roloc TR disc pad (75 mm backing pad - 456-2502).

Tough non-woven disc aggressively deburrs and finishes

The bristle disc is capable of:

Non-woven discs provide a uniformed and consistent performance throughout its lifetime. They are flexible to allow the material to adapt and conform to irregular surfaces. the open construction allows for air curculation for cool operation and reduces the potential for burning.
