Description of Fuller 10393010C 5 Piece Taper Drill
For wood screw sizes #5, #6, #7, #8, and #9. Countersinks combine pre-drilling for screw threads and clearance drilling for screw shank. Countersinks combine counterboring for wood plugs (if needed) and countersinking for the screw head. Plug cutters produce wood plugs to match their counterbores. Made in USA.
Hard to believe this set is still available. I bought a set over 2 decades ago and broke the last one. The high price has long been forgotten due to the high quality of this product. Many Thanks.
