Ratings & Reviews for Kobalt 3 -Piece Assorted High-speed steel Countersink Twist Drill Bit Set
Ratings may include incentivized customer reviews.
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.

Like all the other reviews here, the drill bits themselves broke after 2-3 uses. Couldn't even get it to bore the counter sunk hole in the first place, either.
Broke on first use - zero stars
Would Not RecommendThis is garbage. Bought single 9/64" for $13.88 because they do not stock DeWalt countersinks. It broke on the first hole drilled. It's a bad design and poorly made.

Cheap
Would Not RecommendThe bits were not very durable, I broke two of them within an hour. Find a better product, unfortunately it won't be at Lowes because they don't carry any other brand.

Failed on first use.
One of the drill bits failed and spun in the base on its first use. Exchanged them for a new set

They work as intended.
Would RecommendThey drill the perfect sized counter sinked hole for the intended size screws. The pilot bit is adjustable.
Verified Purchaser
Fast and convenient.
Would RecommendI needed to drill pilot holes so I could put a project together and wanted the screws to be countersunk. These fit the bill.

They are Okay.

very poor quality
Would Not RecommendDrill bit breaks or comes loose in the shank. Drill bit stops in the wood while shank and countersink keep spinning. No repair just trash it.
Just awful
Would Not RecommendThese bits are total crap. All 3 broke with just a couple of minimal uses... And my local Lowe's is refusing to take them back. The bits detached from the hex shank.
