Snappy 43008 1/8 X 3/8 Gold Screw Countersink is a wood drilling accessory built to drill a pilot hole and cut a countersink or counterbore for standard screws in one operation. This is a countersink designed for clean screw seating in woodworking, trim work, and general fastening. Model 43008 uses a 1/8 inch high speed steel twist drill and a 3/8 inch countersink with an 82 degree angle.

What matters here is speed and consistency. Instead of drilling a pilot hole first and then swapping to a separate countersink bit, this setup handles both steps together. That saves time on repetitive fastening jobs and helps keep the screw head sitting at the right depth for a cleaner finished look.

The 1/4 inch hex power bit shank makes this countersink easy to use in impact drivers, drill drivers, and quick-change chucks. On the bench or on site, that hex shank is the practical choice because it cuts down on tool changes and holds securely during repeated drilling.

Snappy sizes this bit for common wood screw work. The recommended screw size is #8 in hardwood and #9 or #10 in softwood, which gives you a clear lane for matching the bit to the job. If you do a lot of cabinetry, furniture work, plugs, or visible wood fastening, that kind of sizing guidance helps avoid split material and sloppy screw seating.

Serviceability is another plus. The listed replacement twist drill is Snappy part 49208, so you are not tossing the whole assembly when the drill eventually wears out. It also works with Snappy's Premium Rotating Stop Collar if you need more repeatable countersink depth for production work or plug cutting.

This countersink is a good fit for woodworkers, finish carpenters, cabinet installers, and serious DIY users who want cleaner screw holes without overcomplicating the setup. If you are driving standard screws into hardwood or softwood and want the head to sit right the first time, this bit earns its spot in the case.
