Lee Valley pocket drilling guide, a simple guide block that lets you drill holes both precisely placed and accurately at 90° without a drill press. Line up the bit with your mark and butt the guide against the bit, flanking it from two sides with one of the V-notches.

Line up the bit with your mark and butt the guide against the bit, flanking it from two sides with one of the V-notches. As you start drilling, the notch keeps the bit from skating so it stays on your mark, and holds it at 90° far better than even the steadiest hand.
Made of case-hardened O1 tool steel to resist wear from spinning bits, the 1 3/4" diameter guide has knurled edges for grip and two notches, one 7/8" tall and one 1/2" tall for shorter bits.
