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.

Clogs easy
Would Not RecommendThe tapered bit wirks great but the cutters on the counter-sink portion clog easily and dont prevent splintering. Would be better if it were like a forstner bit and cut the circle screw head sized and then the counter-sink.
