The bit seems to break too easily in plywood. They are replaceable with regular drill bits, however. Other than the brittle bits, this works well.

I picked up this WildBossy 4-piece countersink set because I was tired of guessing my screw depths and dealing with ugly wood tear-out on my DIY projects. As a woman who loves tackling home building projects, I need tools that are precise, reliable, and work flawlessly to get the job done right. I recently used this set to build a custom entryway bench, and it made the entire process so much smoother. The adjustable depth stop is incredible because it spins freely, meaning it didn't mar or burn the finish on my wood when it bottomed out. Every single screw head sits perfectly flush, giving the final piece a beautiful, professional look. The HCS four-blade design cuts incredibly clean holes through wood without any of the frustrating chatter or rough edges you get with cheaper bits. It also came with the exact wrench needed for quick adjustments and a high-quality screwdriver bit, so I didn't have to go hunting through old toolboxes to get started. It saves a massive amount of time, feels premium, and gave me the confidence to take on even bigger building projects next. Highly recommended!

First of all, it does not have any instructions at all, but you can figure it out. However, by watching some of the videos and reading reviews I doubt everyone knows when setting the screw for the desired bit, you should ensure the flat side of the bit is shown in the hole before inserting it and then make sure you keep it that way when tightening the screw. The description states it has an "Adjustable Depth Magnetic Screwdriver Bit…allowing depth adjustment during screw driving". This has no type of depth adjustment other than sliding the tube over the screw head. It has no feature that reduces over-driving as stated. As far as the part used for drilling the countersink, having a spring on it so it ejects out of your drill is just a waste and totally not needed. However, the worst part of this product and why I am returning it is the "Scratch-guard stop ring" which is what controls the depth of your countersink, just falls off when pointing the drill down which is the position most likely used. Being brand new, I can get it to stay on if I am very gentle and don't shake it or touch the board too hard. After time, I am sure it would become even more loose creating headaches. This should have been designed so the guard does not fall off.
