How do you determine the drill size of tapped holes?
To determine the drill size for tapped holes, you typically refer to a tap drill size chart, which provides the recommended drill bit diameter based on the size and thread pitch of the tap. The general formula used is to take the nominal screw size and subtract the thread pitch to find the appropriate drill size. For example, for a 1/4"-20 tap, you would use a 7/32" drill bit. Always ensure to consider the material being tapped, as it may affect the final drill size choice.
How is a masonry bit used?

What is a grab it drill bit?

Drill bit used for a 20 millimeter tap?
I would use an 18mm or 23/32 drill bit, in general, although it does partly depend on the thread type ( UNF, UNC etc) and the material .

What size drill bit should I use for a 1/4 bolt?
For a 1/4 bolt, you should use a drill bit that is slightly smaller in diameter than the bolt itself. In this case, a 7/32 drill bit would be a good choice for drilling a hole for a 1/4 bolt.

What size drill to you use for a quarter twenty tap?
Depending on the material, I would work with a 3/8 or 11/32 bit for a pilot hole.( If the material is quite soft (aluminium for instance) then I go smaller with the pilot.)
