The right choice of the backing pad
Backing pads for quick change discs are available in grades according to the required application. The firmer the backing pad the higher the stock removal rate. Softer backing plates are suite to working on contoured surfaces and finish sanding.
The QCA 555 (cat. no. 308693) allows use on a regular angle grinder.
Please observe the max. RPM for the backing pads in the product chart.
Two fastening systems have prevailed on the market for the product group ‘Quick Change Discs’. Klingspor can offer you both, Quick Metal Connect and Quick Roll Connect, for all available types.
The system QMC (Quick Metal Connect)
The Quick Change Discs with metal locking are fixed on the backing pad by means of an internal thread.
The system QRC (Quick Roll Connect)
Fix the Quick Change Disc to the backing plate using the plastic threaded bushing and secure by turning 180° clockwise.
