When to choose it

The 1801 makes a broader concave profile than the quarter-inch-radius 1800. Choose it for a trim detail that needs that larger inward curve without changing collet size.

The body reaches 1-1/4 inches at its widest point. Check clearance and the usable reference edge for the B3 bearing before choosing the larger profile.
