You have the answer in the link from post number 3. It's about a drill with a countersink - it nicely makes a recess for the screw heads. Of course, the drilled hole must not be too large in diameter because the screw will not hold properly.
Use wood drill bits to drill holes in wood. They are specially profiled. Conversely, using countersink screws is fun, but it can sometimes take revenge when you screw the screws into a slat that tends to break.
You can drill in hard wood, e.g. oak. You can drill with an ordinary metal drill and nothing will happen. Another thing with drilling larger holes, e.g. fi 8 up, you need special wood drills which, by the way, look similar to metal drills but are sharpened differently.
I meant twist drills, but will the 3mm drill bit be good for all types of screws (the smallest ones for twisting slats, etc.)? I understand that they do not produce smaller ones?
To drill holes in wood for screws, wood drill bits are recommended due to their specialized profile. Countersink drill bits can create a recess for screw heads, ensuring a proper fit. The diameter of the drill bit should match the screw diameter for optimal results. While standard metal drill bits can be used for harder woods, larger holes require specific wood drills that are sharpened differently. For smaller screws, twist drills can be utilized, but the smallest sizes are typically found in modeling sets. Summary generated by the language model.
