These are great for drilling counterboring and countersinking screw holes in one procedure I have used many types of these over the years, some have been excellent some have been woeful these are somewhere in the middle, however for the price and for diy they are good value

Used two sizes of the drill bits, and in both cases after several uses the drill bit came out of the main countersink shaft. Whatever is used by the manufacturer to join the two parts is not good enough for the job. Next time I will go for a better quality and more expensive brand.
