But in the battle of thickness, type 27 is the winner. 

Usage Angle

On the other hand, the type 27 wheel is made to be used at an angle. Since the wheel is meant to grind things. That is why you use the wheel at a 45-degree angle or lower. It can be dangerous to use the type 27 wheel at a 90-degree angle.
