What is a 1A1 resin-bond diamond wheel?
1A1 is a wheel shape/type designation (from common abrasive wheel nomenclature). It generally refers to a flat disc / straight wheel profile (i.e., a simple, face-type wheel rather than a cup or dish shape).
A resin-bond diamond wheel means the diamond grains are bonded in a resin (polymer) matrix, which tends to be more flexible/cushioned than many metal bonds.
In short: a 1A1 resin-bond diamond wheel is a flat/straight diamond wheel (disc type) with diamond held by a resin bond.

Advantages of resin bond for diamond grinding (why it’s used)
Better surface finish: resin bonds often produce a smoother ground surface.
Less chipping: the bond is less brittle, so it can reduce edge/grain-out chipping on brittle workpieces.
Good control in finishing passes: helpful when you need consistent geometry.
Damping effect: resin can reduce harsh vibration compared with very stiff bonds.
