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.

I've bought 3 set. 2 sets broke all 3 bits. Last set is still intact. Store only sold this brand and package. Had no selection.

Pass

Would Not Recommend

The only good part is they are adjustable. Ended up getting a Dewalt set that performed much better. These just felt low quality in comparison.

great tool, makes life easier.

Would Recommend

First time buyer of this type of drill bit and am very pleased. Used them today to put 4 screws to hold a placement fence for guide I am building for my cut off saw. The bit was sharp, easily adjusted to the correct depth and the screws sat perfect in the counter sink.

Quite sharp, with lots of non-obvious uses.

Would Recommend

I bought this set for one particular job and have since found a dozen places where it works better than just a standard drill bit. The tapered drill is sharp, and I use it much like a step drill, but on a much tighter set of holes. It makes a breeze out of drilling starter holes in project boxes for electronics, for example.

junk countersink bits

Would Not Recommend

terrible design drill bit is part to the drive part of the bit. should be like other set I have where drive part is attached to the countersink part and takes a regular drill bit that is replicable if you break it!! had the bit 2 days and broke a bit off, now junk!!!

break easily, bad quality

Would Not Recommend

they broke within a couple days of using them. I have #9 screws, so I first used the #10 one. the drill part broke off the 2nd day after I bought these. so I thought okay I'll try the #8. that one shortly broke later in a different way! the stem for the hex separated. do not buy these!!

Value Pack

Would Recommend

The 3 pack is a much better value than buying these individually. I feel like they aren't the nicest bits, but they work well enough. There was a bit of friction burning happening when I used them, that wasn't happening with dewalt bits in the same wood.
