Ultra-high performance abrasives featuring advanced patented technology for flawless finishing results every time. Exclusive 'Snak-Track' porthole technology draws out the dust at edges and over entire disc surface, eliminating build-up and clogging which provides ultra-long abrasive life. The patented cushioning system allows even dust extraction, reduces heat and allows sanding head to float over the surface; absorbing unevenness, resisting swirl marks and gouging. Assists in reducing fatigue as a result of less required pressure. Aluminium oxide grit and malleable paper covered in a unique abrasive coating ensure uniform wearing.
