Each item number is one diameter and grit combination. Optimum speed depends on the disc diameter, so each item lists its own.
Selecting the right option
A higher grit number is a finer abrasive. The catalogue gives a maximum permitted peripheral speed of 50 m/s and says the maximum rotational speed indicated must never be exceeded. It also says to wear gloves, a dust mask and eye and hearing protection, and to follow the safety instructions (manufacturer-stated). Use a holder that matches the clamping system: SBHR holders are listed under the CDR system (manufacturer-stated).
