Surface Conditioning: Grip Discs FAQs
What is a surface conditioning disc?
Surface conditioning grip discs are a non woven disc which is impregnated throughout the disc to give a great finish and a long life when used for surface preparation and finishing.
Although they can be used for light grinding operations they work best when used for scratch removal, refining and finishing metals.
What speed should I run surface conditioning discs at?
Most people break this rule but for optimum performance scm discs are best run at half the speed of a sanding disc so on a traditional grinder they are best run at between 4 – 6,000rpm.
Why do a lot of your discs have a 10mm hole in the middle?
SCM discs are heavier than traditional velcro discs which makes them more vulnerable to flying off the back up pad. When Cibo introduced the VTMA back up pad with an aluminium nipple in the centre it removed those problems over night.
The VTMA back up pad is available for discs in 100mm, 115mm & 125mm diameters.
