Depends on the pitch:

Fine pitch:

m10 * 0.75 pitch , drill diameter = 9.25 mm

m10 * 1.0 pitch , drill diameter = 9.00 mm

m10 * 1.25pitch , drill diameter = 8.8 mm

Coarse pitch (most common use):

m10 * 1.5 pitch , drill diameter = 8.5 mm

4.50/bag cement, required for 1 cubic metre of concrete ( M10).

Small.

M10 is a globular cluster and thus has no real defining boundaries.

The M10 core is approximately 35 light years wide, whereas the spatial diameter is around 83 light year across.
