What Customers Are Saying

The adjustable countersink drill bit offers versatility with 3 different bit sizes to accommodate a range of screw sizes. The adjustable collar allows for easy control of the countersink depth, creating a professional-looking finish. Many users found it to be a time-saver, allowing them to drill and countersink in a single step. However, the drill bit can be prone to breaking or wearing out prematurely, especially on harder materials. Some users also experienced issues with the bit becoming loose or wobbly during use, affecting accuracy. Careful use and consideration of the bit's limitations are advised.

I’ve used this countersink bit for hundreds of screws For my new project! It’s been huge to be able to fill in holes and make it look furniture-grade. Thankful for Lowe’s and their military discount!

Is it a Useful Tool?

Would Recommend

Have not had a chance to use it yet. I think if you are not careful in how you hold it, it is still possible to miss centering your hole. But it should help

Its fine. Works well, but a bit overpriced. Can find similar suitable bits online. Not fancy brands, but they will do the trick.
