What Customers Are Saying
This adjustable countersink drill bit offers versatility with its 3 interchangeable bits to accommodate a range of screw sizes. The adjustable collar allows users to easily control the depth of the countersink, and the self-centering design helps produce accurate, professional-looking results. However, some users have reported issues with the drill bits breaking or wearing out quickly, especially on harder materials, and the set screws may loosen during use, causing instability. Replacement bits can also be difficult to find. With proper care and maintenance, this tool can be a useful addition for DIY projects and light-duty work.

Would RecommendI should have had a smaller dia bit for the drawer glides screws. Bit depth a little short. Fair price
From 7_SLASH_64-in 6-in High-speed steel Self-Centering Hinge Bit Verified Purchaser
It works but...
Would Not RecommendThe spring in this is so strong that it's difficult to push down while holding the bit and part in position. It wants to move the piece you are drilling the hole for and that defeats the purpose of a self-centering bit.
From 5_SLASH_64-in x 6-in High-speed steel Self-Centering Hinge Bit Verified Purchaser
Works with some modifications…
Would Not RecommendFirst the hex Chuck adapter came off; fortunately it still works without it. Then the tip of the bit broke off. I was able to grind the point down so it still works. Only saving grace is that you can swap the countersink part over to another bit.
From 9_SLASH_64-in 3.55mm #6 Standard High-speed steel Countersink Twist Drill Bit Verified Pro
Nice set for almost any size screw
Would RecommendWhat I like: 3 bits to accommodate most typical screw sizes, Adjustable collar to adjust depth of plunge, Replaceable bits, Affordable price. What I don't like: Countersink heads do wear out, and work best on softer woods and composites.

Adjustable drill bit length is easy to change.
Would RecommendAdjustable drill bit is easy to change the length of the hole it drills. I have had some that the set screw was hard to adjust and would not hold drill bit in place.
