7.1 Set Hole Spacing
The Handy-Drill backgauge has been set to drill standard three-ring holes, plus one extra stop for
four-hole drilling. The stops are held in place with setscrews that run through the top of the stop. Use
the 3/32” hex wrench provided in the toolkit in order to loosen the setscrews. Slide the stop to the
required dimension as read from the scale on top of the backgauge. Tighten the setscrew until the
stop is held firmly in place.
7.2 Set Drilling Depth
Turning the adjustment knob on top of the machine sets the depth to which the machine will drill. To
drill deeper, turn the knob counter-clockwise. To drill shallower, turn the knob clockwise. The drill
depth should be set such that the bottom sheet is cut through without going excessively cutting into
the drilling block. Use scrap pieces of paper to set the drill depth.
Important: Always check and adjust the drill depth whenever changing drill bits. The adjustment
range will accommodate both 2” and 2-1/2” drill bits.
