What is the Difference Between Socatt & Roloc Quick Change Sanding Discs?
The history of quick change discs goes back quite a long way. The Socatt quick change system was developed over 40 years ago by Standard Abrasives in California. The Socatt system was the only quick change disc system for quite a number of years before 3M decided to develop a competitor system called RolocTM.
Socatt Discs
Socatt discs have a metal to metal fixing on the back of the abrasive disc locking into a metal holder on the back up pad. It creates a stronger fixing than the Roloc but it is a little less flexible.
Each Socatt button is unique to the particular diameter.
Cibo Abrasives manufacture their own Socatt discs using the same metal fixing.
All part numbers for the Socatt abrasive discs in the Cibo range begin with QS (quick change – Socatt). For example QSMA/5/75 are the unitised density 5 finishing discs (pictured).

Roloc Discs
Roloc quick change discs use a plastic button on the back of the abrasive disc which screws into a female thread on the back up pad.
The RolocTM button is the same size regardless of the disc diameter which allows more flexibility to change between disc diameters. For example, a 75mm Roloc disc can be used on a 50mm back up pad. Thus increasing the options for how RolocTM discs can be used.
Cibo make their own Lockit / RolocTM system using the same button fixing as 3M.
All part numbers for the Roloc abrasive discs in the Cibo range begin with QL (quick change – Lockit). For example QLPP/80/75 are the 80 grit ceramic sanding discs (pictured).

Why Choose Quick Change Sanding Discs?
Cibo Roloc and Socatt coated abrasive discs are normally manufactured with a 2-ply backing structure to increase the strength and performance of the abrasive discs.
