To convert to mandrel for blind hole use.
When honing any blind hole the stone must be flush with the end of the mandrel.

The range of mandrels listed above can be converted for blind hole use simply by changing the expansion wedge and stoneholder type and front and rear stops.
 
Use F2 type stoneholders mounted with the appropriate stone grade. Move the front stop from the first hole at the front the mandrel to the second hole in the mandrel hole.
 
Move the rear stop to the last hole in the mandrel body.
