There is one small area, or drill point, on S&G locks that is outside of the dial, where if we drill a hole and insert a scope with a 90 degree view, the wheels are visible.  This small area covers only ¼ inch.  Drilling for and hitting this area is no problem if you are using a Little Giant and a drill rig.  The Little Giant locates the area and guides the drill bit.  The drill rig drills the hole straight in without angling off.

When drilling a spy proof dial, start by setting the dial on " 82 ".   Mark the face of dial at " 82 "using a Marks-A-Lot.  Now, set dial at " 0 " and transfer the mark to the dial ring.  Mount the Little Giant onto the dial ring, centering jig on the dial ring mark, and tighten the chain securely Drill at 1,000 – 2,000 rpm.  Keep drilling until the drill bit touches the back of the lock case.  Remove equipment, and scope lock open.

Do not attempt to drill this hole by hand. The drill bit will jump in and jam. The screw feed allows the drill to machine a hole without jumping in and jamming.

There are four secret drill points.
For locks mounted R.H. 1 11/16 x 82.
For locks mounted V.D. 1 11/16 x 57.
For locks mounted L.H. 1 11/16 x 32.
For locks mounted V.U. 1 11/16 x 07.

When drilling locks mounted V.U. a Little Giant is not used.  Start hole by hand, and finish using a drill rig.  When drilling S&G Locks with a flat dial, start hole by hand, and finish using a drill rig.

Tips on scooping S&G locks using this drill point.  Turning left, park the first wheel where you can clearly see one side of the gate.  Note and mark down the number. Turning right, park wheel number two with its gate lined up with the number one gate.  Note this number and mark it down. Turning left, park wheel number three with its gate lined up with one and two.  Note this number and mark it down.  You now have a combination. Work this combination, and make sure the gates line up.   If they do you are now ready to transfer to the drop in at 97.  Drop in will be about 12 numbers away.   Subtract 10 numbers from each and work combination.  Next subtract 11 numbers, etc. until lock opens.
