This aluminum jig can be used on a benchtop, or remove the drill guide blocks for use clamped directly to the workpiece. It works great both ways.…
It comes with two guide blocks, one for 3/4"-thick wood with the guide holes set 5/8" apart; and the other for 1-1/2"-thick wood with the guide holes 1" apart. Each guide block has a magnet built in so the included locking pliers will hold fast to them during portable use, a handy feature. The toggle clamp worked well at holding workpieces in the jig, but adjusting it took trial-and-error tinkering to get the right tension. The drill bit cut clean, precise holes longer than most jigs.
