B-40 is a new additional Medium Stone asked for by our World Cup technicians
New version uses a light-weight Composite backer wheel instead of the original aluminum backer. Less vibration, more torque and speed for cleaner cut. Single sided highest quality 75% cubic diamond stone.
- B-40 is still consider a Medium stone with a slightly finer finish than the B46 medium stone
- Used in GS on WC
- Also a good option as a everyday stone if looking for slightly finer finish then the B46 stone
Compatible for use on Af-WC, Af-C, Af-L and Af-1 Snowglide machines
