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.

Would Not RecommendOn first use of the product, in hard wood, the drill broke off at the counter sink. Poor material used in making the product. Don't but unless you plan on using in pine or other softwood.

Hex screw doesn't grip tightly
Would Not RecommendMy No.10 hex screw got hot and allowed the drill bit to slide the first day i used it. I have not used other sizes as much to see if they loosen with multiple use. I may opt for a higher quality bit.

Not the fanciest, but they get the job done...
Would RecommendThese countersink/counter bores will get the job done. They don’t work as well in hardwoods as the tapered bits, but they work just fine in softer wood and plywood. The price difference is considerable, with the set of 4 sizes costing less than a single tapered bit. Definitely worth it to have these!

Not sharp!
Would Not RecommendI had Stanley like these decades ago - Kobalt was horrible and did not cut well at all, they burred the wood. Do not recommend. Misplaced the receipt, or would have returned them...
Wobbly countersink drill bits
Would Not RecommendThe countersink bits works alright, only the drill bit is not completely straight.

Good bit set
Would RecommendThe little bit makes a nice recessed pilot hole for my screws so my wood doesn’t split. Works well for me!
