RE: RE: RE: Drilling question for anyone with drilNo you don't wedge off at surface, you start a hole with a large drill bit to a pre-determined depth to allow for easy wedging in the future (if you had it in mind ahead of time to do so) then continue your hole with a smaller bit to your target depth. Makes it easier to wedge off later in the larger bore hole.
At any rate the depth of the wedge off hole is irrelevant to figuring out the horizontal distance between the two holes in simple terms.
