Proper hole preparation for wood screws usually takes three steps—drilling a pilot hole, a clearance hole, and a countersink—followed by installing the screw. It’s time-consuming, which is why many woodworkers skip it, often leading to weak joints or split wood.

The Sawinery Countersink Drill Bit Set simplifies all of this into one step by combining a tapered bit with a built-in countersink. Matched to the three most common wood screw sizes, it speeds up assembly without sacrificing strength or risking damage.

Includes countersink drill bits for #6, #8, and #10 screws, covering the most commonly used wood screw sizes.
Tapered Drill Bit Design:
Ensures a wide clearance for the non-threaded part of the screw while creating a pilot hole for the threaded section, reducing wood stress.
Depth Control:
The adjustable stop collar allows precise countersink depth, ensuring screw heads sit flush with or below the wood surface.
Counterbore Option:
By removing the stop collar, the countersink functions as a counterbore, creating space for wood plugs to conceal screws.
¼-Inch Hex Shank:
Provides a secure grip with drill chucks and is compatible with impact drivers, ensuring reliable performance across tools.

I usually don’t leave reviews, but I had to for these. I bought them while working on a farmhouse-style coffee table, and they made the assembly so much easier. No splitting, no misaligned screws, just perfect countersinks every time. The ability to remove the collar for counterboring was great when I wanted to hide screws with wood plugs. A must-have if you do a lot of woodworking.

These countersink bits are a huge upgrade from my old ones. I used them to install trim and shelving, and the difference in quality is noticeable. The tapered bit helps seat screws smoothly without cracking the wood. Every screw head sits flush, which gives the project a much cleaner finish. I should have bought these years ago.

I bought this set while working on a set of bookshelves, and I wish I had picked them up sooner. No more guessing with pilot hole sizes or fumbling with multiple drill bits. The three included sizes cover everything I need, and the countersinks leave a clean, professional-looking finish. I tested them in both softwood and hardwood, and they performed equally well. Great tool if you want to get consistent screw placements with minimal effort.

These bits are pretty handy to have around. I used them on a couple of small DIY projects, and the results were really clean. Adjusting the depth collar took a little trial and error, but nothing too frustrating. Overall, a good buy.

This set works exactly as advertised. The tapered bits are awesome for keeping screws snug, and the countersinks leave a clean finish. I’ve been using these for some furniture repairs, and they’ve held up great. The hex shank fits nicely in my drill, and swapping sizes is quick.
