Mechanical Locking
image of products on page

These discs have plastic inserts attached to the back which screw into their respective holders. They are meant for very high RPMs which would normally cause a PSA or Hook & Loop disc to detach.

There are three main attachment systems:

image of products on page

A: ROLOC® initially introduced by 3M® has a male screw attached to each disc.
The ROLOC® holder is female.
B: METAL BUTTON has a female button attached to each disc.
The metal button holder is male.
C: POWER-LOCK® introduced by Merit® has six plastic sides which snap into a female holder of same design.
We stock all three types of discs and holders. The discs are either cloth backed abrasive or non-woven fiber similar to surface condition discs. Sale prices are listed in red.
