A two-cone set for the Robust Live Center.  Sold only as a set of two.  One is a pointed cone  (max. diameter is 1 1/4", length is 1 1/2") while the other is a large bullnose type cone (max. diameter 4", 1 1/2" length) that can be mounted in two different orientations.  Cones are great to go into a drilled hole when making handles, pepper mills or any project with a drilled or turned hole.  The larger cone is helpful for support when making goblets, vessels or boxes where the extra support on the tailstock side is a benefit.
