Ratings may include incentivized customer reviews.
What Customers Are Saying
The product received mixed reviews. Many customers praised the quality and performance, noting the bits were sharp, made clean countersinks, and had a useful adjustable depth feature. However, some experienced issues with durability, reporting the bits broke or became dull after limited use, especially when drilling into harder woods. A few felt the pilot holes were not long enough for one-step drilling and countersinking. Overall, the consensus is this is a good quality, affordable set that works well for softer woods, but may not hold up as well for more demanding applications.

Countersinking Twist Drills
Would RecommendThese countersinking twist drills work fine for their intended purpose. It would be nice if the pilot drills were a bit longer, to allow you to drill and countersink in one step, for the screw length in which you are using. But it's no big deal. You can simply drill to correct depth with a twist drill, and then finish with the countersinking drill. Seems to work fine.

2nd Only to my Phillips Bit in frequency of use
Would RecommendI use a drill-drive set every single day in my work. Drilling and countersinking in one operation is quite convenient. These refills are of good quality and are plenty sharp.

Don't Buy - Only for softwood
Would Not RecommendI bought these to replace a broken countersink. They all broke on first use when drilling into Kitchen cabinet faces.

Nice bits
Would RecommendThey do exactly want I wanted, no issues. Would be nice if there was one smaller bit. I am using finishing screws which have a very small head.

Work as Designed
Would RecommendWorks great, I was originally a bit annoyed that I had to purchase 4 bits as I only wanted the one small bit but am now glad I have the set of bits, since I've already had occasion to use more than just the one I originally needed. I've use both of the smaller 2 and they work like a charm, no wood splitting and a good result.

Fence building
Would RecommendWe used the bits while building a fence. They made the job much faster and easier...and not one split board!
