This countersink set contains five countersinks for the most popular wood screw sizes, No 6 thru No. 14 with 3/8-in and 1/2-in cutting diameters. It also includes matching taper point drill bits, plug cutters and stop collars.
To drill for the shank and thread of screws, countersink for heads and, if necessary, counterbore so that wood plug can be inserted over the head.
We stock all countersinks, drill bits, plug cutters, stop collars, screws and hex keys for individual replacement and we have many other sizes of all in stock.
