DRILLING DEPTH GUIDELINES
The figures in these tables have been calculated, based on
field experiences, and may be reasonably expected. Ratings
are based on a vertical, straight, clean down hole using a
18 258 kg (40,000 lb) hoist (single line pull). Actual drilling
capacity will depend on in-hole tools, conditions, drilling
techniques and equipment used.
