Some time ago someone posted the need to produce dowel of varying length and I knew I had a set and they turned up today whilst rooting in workshop so posted a few pics they were from BJR and I've had em since the 90s still going strong
Theres 5 cutters in the set 3/8 1/2 5/8 3/4 and 1" all capable of cutting 3" long dowels or short screw plugs in any wood there for use in a pillar drill
