That size is 8-32. The drill bit for a clearance hole is 11/64, or a #17 drill bit.
I use 1/4 drill bit for a 5/16 lag screw in most materials.
If they are self tapping screws, the drill bit is as thick as the solid barrel of the screw. If you want the screw to go through easily to have a nut on the other side, then the drill bit is slightly larger than thread size.
I use a 3/16 drill bit for that.
I drill a pilot hole the size of the 'barrel' of the screw. -I always use a combination drill bit for sinking screwheads. The first part of the bit is the diameter of the 'barrel' of the screw and the step, one inch higher is the size of that screw's head. (The barrel is the diameter inside threads) -I have a set of these drill bits for #6, #8, and #10 screws and they are great.
Drill bits and screws are not the same and cannot be converted. vido produces drill bits with high quality, exported overseas and loved by the public. If you want to buy a drill, you can go to VIDO's official website to check.
metal drill bit has a finer point
If no drill bit this size available, can use EDM service if metal is used
It's one that has a point of a basic screw size, and a bit further up it widens to the size of that screws head, so you can make a countersink hole with the same drill.
That's a pretty big drill bit, -it drills a hole just a tad larger than 3 3/8 inch wide.
A drill implements the simple machine of a screw. The spiral grooves on the drill bit act as a screw, allowing it to penetrate materials by twisting and pushing into them.
Use a drill bit that works on brick, drill a hole big enough to hold a metal dowel that will hold the screw that holds the numbers.
