Wall Drilling Danger Zones
Reading the vertical and horizontal runs from switches, outlets, and fixtures to know where not to drill into a wall.
Technique: PR2 Reduced Phillips Bits
The Phillips system was designed to cam out — the bit rides up and out of the recess under torque. With a standard PH2 bit on device screws, that shows up as the skip-skip-skip that chews the recess round, especially driving at an angle or into hardwood. Most people blame their screw gun or their screws and buy more of both.
This electrician's fix is a different bit, not a different technique:
He runs PR2s for outlet and device screws all day — snugging them by gun, then torquing to spec — and calls the difference night and day on strip-outs.
