The drill size to be used for creating a hole before threading for M6x0.5 tapping is 5.0mm.

• The recommended drill size for M6x0.5 tapping is 5.0mm.

• The drill size is determined by subtracting the pitch (0.5mm) from the major diameter (6mm) of the tap size.

• In this case, 6mm - 0.5mm = 5.0mm drill size.

• Using the correct drill size ensures proper thread engagement and a secure fit for the M6x0.5 tap.
