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.

Would RecommendI've used 2 of the 3. They cut red oak like a hot knife through butter.

junk
Would Not RecommendBroke off in the wood the 2nd time we used them
Very fragile
Would Not RecommendThey break under moderate load. I’m not a pro but I’m the son of a pro. I appreciate having the right tool for the job, even if it’s just around the house. I also take care of my tools. So, I bought these bits to help create a clean look on some deck repairs. However, I had multiple bits snap in composite decking. I also had the hex shank come loose from the bit.
3 Piece Drill Bit Set
Would RecommendVery well made. Collars hold in place and bits are very sharp. Bores through quickly and cleanly.

Great countersinks
Would RecommendThese make great countersinks for using countersink screws. The three sizes are perfect for most screws. They work great!

Pleasantly surprised
Would RecommendRebuilding an old wooden boat with hundreds of holes to drill and countersink using a cordless drill. Drilling Plywood skin and white oak frames underneath. Been surprised at how well they have worked. Drilled proabaly 200+ holes so far and no issues at all. Just broke my #8 but I have used it a lot by hand and never expected it to last this long. Going to pick up another set shortly. Good deal for the money!
Love the drill. But...,...
Would RecommendThe long drill is great but once you break them you have to buy the whole thing. There are no replacement bits for this item. Keep them and don't break them, then your in luck. Break your favorite one and then your in trouble. There is no replacement and your spending another $20 on them.
Counter sink drill bits
Would RecommendThis is something I have been without for far too long. I am glad I invested in these bits because it eliminates one extra step which on big projects is now less time consuming. Well made and a great addition to your tool box.

Works as expected.
Would RecommendI didn't have any doubts, but these work just as you would expect them to. Also, the price is pretty reasonable for a set of 3.
