Useful for the hobbyist
Would RecommendThe countersink collar is locked in position by two set screws. It would loosen during use due to vibration. It is still a useful tool if you only need to countersink different sizes occasionally.

Counter sink and bore that is a pleasure to use
Would RecommendI have used a bunch of these over the years and for the money, this one is the best value - stay's sharp, hole and after hole - clean edges on the bore and screws fit snuggly.

Kobalt 9/64-in Standard High-Speed Steel Twist Bit
Would RecommendWorks like it should. What else can I say
From 9_SLASH_64-in 3.55mm #6 Standard High-speed steel Countersink Twist Drill Bit Verified PurchaserSweepstakes
Poor design
Would Not RecommendAfter drilling a total of 6 holes the quick release end broke off causing the drill bit to bind and bend. I could not used it after that due to the bit made to big of a hole in the project due to the bend. Price was a bit high but I needed this for a specific project. Don’t waste your money

Pilot Drill
Would RecommendThis drill is great for drilling pilot holes for hinges , it keeps them centered so no movement when putting screws in because of out of centered screws.
