Product Description
The combination of a quality high-speed tapered drill with a countersink and stop collar, in conjunction with the correct plug cutter, is by far the best way to prepare fine work for wood screws. This 12-piece set, designed for cabinetmakers, includes drills and countersinks for #5, #6, #7, #8 and #9 screws, a 3/8" plug cutter, a stop collar and an Allen wrench, all in a foam lined plastic case. Tapered drills afford greater gripping power for screws than standard twist drills because they match the tapers of their corresponding screw sizes, allowing the screw to grip along its entire length. Our matching countersinks are made of high carbon steel and have four flutes for clean, accurate boring with minimum tear-out. They are adjustable along the length of the drill and can be tightened with two set screws. The stop collars are also adjustable for varying counterbore depths and can be set just behind the countersink cutters when a counterbore is not necessary.

Customer Reviews
This countersink may seem a bit expensive but they are worth the money. I purchased a set of these about 10 years ago and as a wood worker I use them a lot. The bits seem to have a double taper and with the adjustable countersink they can be adjusted to most any screw. They have worked flawlessly for me and the only reason I have purchased the recent replacement set is because I dropped my cordless drill a couple times and broke several of the drill bits. I tried replacing the broken bits with cheaper box store replacements and quickly realized you get what you pay for, thus the recent purchase. I have set thousands of screws in different projects and remodels over the years and these drill bits have worked well for me. I have not used the plug cutter in the set very much and have no opinion as to it's performance. If I had any complaint I guess it would be that I wished it came in a more durable storage box.
