Set of 7 different drill bits (3 mm/4 mm/5 mm/6 mm/7 mm/8 mm/10 mm) and comes with a hex key.

User-friendly design: Use the hex key to remove five-sided countersinks or adjust the countersinking and drilling depth for screws of different lengths.

Versatility: The countersink drill bit set contains 1 hex key and 7 countersink bits (7 different sizes) to meet all your drilling needs.

Ideal for wood, fiberboard, particleboard, plywood, plastic, PVC, rubber, and more. Suitable for bench drills, hand drills, and traditional electric drills.

Tip: Step 1: The drill bit must be completely vertical when drilling! Otherwise, it will break easily. 2: If the drill bit is damaged, simply replace it.

3: We recommend using an electric drill, which gives better results than a hand drill, which is not secured during operation and can bend and break.
