What Customers Are Saying

Customers praise the product for creating clean, precise countersinks and pilot holes with adjustable depth control, and many report professional results on woodworking projects like decks and cabinetry. The three-piece set covers multiple sizes effectively. However, a substantial portion report premature failures, particularly at the hex shank connection, with bits snapping or coming loose after just a few uses even in soft wood. Reviewers describe the metal as feeling cheap and fragile. While functionality impresses initially, durability concerns and structural design flaws leave many questioning long-term value.

Love them!

Would Recommend

Can't say how many sets I've bought from other brands - but they nearly ALL broken a point within the first few uses. Not Kobolt's - DURABLE! I also love the adjustable pilot hole feature so I dont get any holes where I DON'T want them!!!

Drill bits

Would Recommend

These 3 bits are exactly what I needed. The three pack was cheaper then buying individually. They worked great in hardwood and softwood. Will buy again

Cheaply Made

Would Not Recommend

Like others have said, the hexagonal portion that goes into your drill chuck is press fit onto the countersink portion instead of being one piece. This seems to fail regularly.

This drill set was just as I was looking for. The price was good, and the quality was real good. I was having trouble locating a single bit, a nice young man (employee) came and found this set for me, as I was about to give up. Thanks to Him and to Lowes' I can now finish my project.

So much easier

Would Recommend

I guess these have been around for a while, but what improvement over drilling the hold, changing bits and doing the countersink. Three sizes is very convenient too. Using the dickins out of them

Don’t waste you’re money.

Would Not Recommend

I bought these to complete a headboard and bed frame that I’ve been working on. The first hole I drilled the bit broke off in the wood and I had to take apart everything I was working on to hammer the bit back out.

Counter Sink Drill Bits

Would Recommend

Purchased these counter drill bits to install bathroom cabinets. They worked great and were easy to use. I would recommend when you need to counter sink a screw.

Good Quality and Good Adjustability

Would Recommend

I bought this set for a project in which I needed to drive about 200 #8 screws into 3/4" MDF. I had to adjust the countersink depth twice based on the screws I was driving. I didn't notice that there were two set screws with the first adjustment, but the countersink held very well with only one screw tightened. The bit held up perfectly throughout the project. I'm quite pleased with how these work.
